The +runner mirrors that contract: pi-ai resolves `spec.model` to a Model +with the correct api shape per provider (`openai-completions` / +`openai-responses` / `anthropic-messages`), and +[`posthogAiGatewayModel`](../../../products/agent_platform/services/agent-runner/src/models/ai-gateway-model.ts) +overrides only `baseUrl` (with the shape-appropriate suffix) and the +`provider` tag. OpenAI agents hit `/v1/chat/completions` or +`/v1/responses`; Anthropic agents hit `/v1/messages` — all on the +same gateway. + +If the gateway returns `unknown model` for a model that works direct, +the gateway's `modelTable` (`ai-gateway/internal/router/chain.go`) +needs a SKU alias for pi-ai's name (e.g. pi-ai says +`claude-sonnet-4-6`, the gateway's primary SKU for the same model +is `claude-sonnet-4-5`). Ping the ai-gateway team — it's a one-line +addition. + +## Driving the stack: three paths + +### 1. `bin/run-agent` — the smoke test + +Fires a chat trigger against the canned dev revision and tails SSE: + +```bash +bin/run-agent # default app (slug=demo) +bin/run-agent --input='{"foo":"bar"}' +bin/run-agent --no-listen # skip SSE tail +``` + +Validates the full ingress → queue → runner → bus → SSE path with one +command. Reach for this first when anything changes in any of the three +services. + +### 2. Local MCP — end-to-end via an MCP client + +The `agent_platform` Django endpoints (`/api/projects//agent_applications/...`) +are exposed as MCP tools, generated from the OpenAPI schema into +[services/mcp/src/tools/generated/agent_platform.ts](../../../services/mcp/src/tools/generated/agent_platform.ts). +That means once the local MCP server is running, an MCP client (Claude +Desktop, MCP Inspector, claude.ai) can: + +- create + list agent applications +- create draft revisions, write bundle files via the janitor proxy +- freeze + promote +- (downstream) trigger them via ingress + +Bring up the MCP server alongside the agent stack: + +```bash +# Already wired into hogli — select the mcp_server capability. +# Or standalone: +cd services/mcp && pnpm run dev # → http://localhost:8787/mcp +cd services/mcp && pnpm run inspector # web UI to call tools by hand +``` + +Wire Claude Desktop or Claude Code (see [services/mcp/CONTRIBUTING.md](../../../services/mcp/CONTRIBUTING.md#testing-with-claude-desktop-macos)). +The same config shape works for Claude Code — add the server to +`~/.claude/settings.json` or a project-level `.mcp.json`: + +```json +{ + "mcpServers": { + "posthog-dev": { + "command": "npx", + "args": [ + "mcp-remote", + "http://localhost:8787/mcp", + "--header", + "Authorization: Bearer " + ] + } + } +} +``` + +Then in the MCP client you can issue real authoring tool +calls against your local Django + janitor. This is the path +to use when reproducing what an authoring AI would see, or when +validating that a Django serializer change flowed through to the MCP +tool surface (`hogli build:openapi` regenerates [services/mcp/src/generated/agent_platform/api.ts](../../../services/mcp/src/generated/agent_platform/api.ts)). + +When you change a serializer or viewset under `products/agent_platform/backend/`, +**always rerun `hogli build:openapi`** before testing via MCP — the MCP +tool schemas come from the generated OpenAPI and silently drift otherwise. + +### Gap: no MCP tools for invoking a created agent + +The `agent_platform` MCP surface today is **authoring-only** — `agent-applications-*` +and `agent-applications-revisions-*` cover create / edit bundle / freeze / +promote, but there is no MCP tool that wraps the ingress runtime endpoints +(`/agents//run`, `/send`, `/listen`). After an authoring harness like +Claude Code creates and promotes an agent via MCP, it has no in-band way to +then talk to it — the next step ("invoke the thing I just built") is not +discoverable from the tool list. + +Workarounds until invocation tools land: + +- `bin/run-agent --slug=` from a terminal pane. +- `curl -XPOST localhost:3030/agents//run -d '{"message":"hi"}'` plus + `curl -N localhost:3030/agents//listen?session_id=...` for SSE. +- The [`agent-authoring-flow.md`](../plans/agent-authoring-flow.md) plan + covers the proper fix: dedicated `agent-invoke` / `agent-send` / + `agent-listen` MCP tools (and a scripted test-run surface) so the + authoring AI can iterate end-to-end without leaving MCP. + +## E2E tests — `products/agent_platform/services/agent-tests` + +Every vital platform feature has a case in +[products/agent_platform/services/agent-tests/src/cases/](../../../products/agent_platform/services/agent-tests/src/cases/). +The harness ([src/harness/cluster.ts](../../../products/agent_platform/services/agent-tests/src/harness/cluster.ts)) +boots ingress + runner + janitor in-process against a real test DB, +real filesystem, real express, real Worker, real PiAiClient — mocked +**only** at the model layer via pi-ai's `faux` provider. You arm the +script per test: + +```ts +c.setScript([fauxText('hello world')]) +await c.deployAgent({ slug: 'echo' }) +const res = await request(c.ingress).post('/agents/echo/run').send({ message: 'hi' }) +await c.drain() +``` + +Run them: + +```bash +pnpm --filter @posthog/agent-tests test # full suite (faux) +pnpm --filter @posthog/agent-tests test cases/chat # one case file +``` + +Requires `agent_runtime_queue_test` to exist locally (`bin/migrate +--scope=agent_runtime` creates `agent_runtime_queue`; the test DB is a +sibling). The harness drops + reapplies schema per test, so DB state +is never shared between tests. + +### Vital-feature coverage rule + +If a feature is user-visible and could regress (a new trigger type, a +new lifecycle state, a new tool category, a routing edge), it needs a +case in `src/cases/`. The naming is one-file-per-concern — see existing +files: `chat-trigger`, `slack-trigger`, `worker-resume`, `strict-principal`, +`approval-gated` (when it lands), etc. Add yours next to them. + +### Real-inference variant + +[src/cases/real-inference.test.ts](../../../products/agent_platform/services/agent-tests/src/cases/real-inference.test.ts) +runs the same harness against a real provider model. **It runs by +default and fails if no provider key is found** — that's the only way +to know v2 talks to a real model end-to-end. Key discovery order: + +1. `POSTHOG_AI_GATEWAY_KEY` + `POSTHOG_AI_GATEWAY_URL` → ai-gateway +2. `ANTHROPIC_API_KEY` → Anthropic (default `claude-sonnet-4-6`) +3. `OPENAI_API_KEY` → OpenAI (default `gpt-4o-mini`) + +`.env` at the repo root is loaded automatically. + +Opt out in CI without provider creds: `AGENT_SKIP_REAL_INFERENCE=1`. +**Do not opt out by default in local runs** — losing real-inference +coverage is how silent drift in pi-ai integration sneaks in. + +### Per-service unit tests + +The harness covers the platform integration story.

Anything that crosses two services belongs in +`agent-tests`, not in a per-service test. + +## Debugging recipes + +- **Session stuck in `available`** — runner not picking it up. Check + the runner pane for errors, and verify `AGENT_DB_URL` matches the + DB the ingress wrote to. +- **`session.revision_missing` in runner logs** — `POSTHOG_DB_URL` + is wrong, or you enqueued against a revision that isn't `live`. +- **Janitor 401 on `/native_tools`** — `AGENT_INTERNAL_SIGNING_KEY` + (Django) doesn't match the same env var in the janitor.

Per-caller + isolation belongs in `jwt`. We tried this twice (PR 63930 added a + spec-level `caller_id_header`; the followup refactored it to the + conventional `x-posthog-caller-id` header) and reverted both — + re-introducing it should require a threat-model write-up, not a + review nit. + + This means the original threat-model finding F5 ("any holder of the + agent's shared secret can resume any session keyed under it") is now + the **documented model**, not a latent bug. The platform-level + mitigation is to scope each `secret_ref` to a single upstream + integration; multi-tenant isolation is `jwt`'s job. If a future use + case genuinely needs continuity _with_ per-caller isolation under + `shared_secret` (today it doesn't), the design path is + **server-issued unguessable resume tokens** (random token returned + on session create, required on resume), NOT a self-asserted caller + header.

If you're tempted to add `express` or `startServer`, + you're in the wrong package. + +2. **Interfaces first, then one real impl.** Every cross-process + boundary (queue, bundle, sandbox, bus, log sink, identity, secret) + is an interface here, but there is only one concrete impl per + boundary and it's the one prod runs (`PgX` for persistence, + `S3X` for storage, `RedisSessionEventBus` for the bus, + `KafkaLogSink` for logs, …). The test harness wires the same + classes against real local services (Postgres, Redis, Kafka, + SeaweedFS) — no fakes, no in-memory shortcuts. The rule is + "if it's stateful and it diverges silently from prod, delete it" + — that's exactly what bit us before this refactor. + +3. **`AgentSpecSchema` is the contract — change it carefully.** + Tightening a field can reject revisions Django happily wrote. + Loosening can let the runner accept specs that downstream code + can't handle. Mirror janitor `validate-spec.ts` whenever you + touch this. + +4. **Schema lives in `@posthog/agent-migrations`.** This package no + longer carries inline SQL constants. New tables or columns go in a + new migration file there. Test harness pulls `reset()` from the + migrations package; production runs `bin/migrate --scope=agent_runtime` + before service boot. **Never** ship a feature that runs `CREATE +TABLE IF NOT EXISTS` at runner / janitor / ingress boot — schema + drift then becomes silent (column adds no-op) and prod tooling + that depends on `pgmigrations` is bypassed. + +5. **Cross-process services are constructor-injected, not module + singletons.** Wire each impl at the entrypoint and pass it through + `WorkerDeps` → `runSession` → dispatcher into `ToolContext` (see + `memoryStore` for the worked example). Tests inject the same real + impls; they don't construct fakes. No `setX()` / `getX()` global. + The pre-existing `posthog-client.ts` / `memory-broker.ts` + (deleted) pattern is the antipattern we're moving away from. + +6. **Prefer well-tested libraries over hand-rolled rankers / + parsers.** MiniSearch (`@posthog/agent-shared`'s `search.ts`) is + the precedent: a ~7KB dep that gives BM25 + field weighting + IDF + without us having to get it right. The same logic applies to YAML, + markdown, regex-glob, etc. — if it's load-bearing in prod, swap + in the off-the-shelf option even when the hand-rolled version "works." + +7. **No `process.env` reads outside the typed config loader.** Every + env var the agent services depend on goes through + `PlatformConfigSchema` (here) or the service's + `extend(...)` schema (in each service's `src/config.ts`), with an + entry in `PLATFORM_ENV_KEY_MAP` / the service's `ENV_KEY_MAP`. + Service `index.ts` reads `loadConfigFromEnv(...)` once at boot and + passes the typed object onwards. Don't reach for `process.env.X` + inline — it bypasses the schema (no default, no validation, no + prod fail-fast). The platform-shared fields (DB URLs, REDIS_URL, + ENCRYPTION_SALT_KEYS, HTTPS_PROXY, …) belong here so every service + gets them for free; service-specific knobs go on the service's own + schema. Also forbidden in tests: pass an explicit `env` object to + `loadConfigFromEnv` instead of mutating `process.env`. + +8. **Two HTTP clients, deliberately separate.** Every outbound fetch + goes through one of two classes in + `agent-shared/src/runtime/http-client.ts`: + - **`HttpClient`** (proxy-bound) — default. Wraps `undici.fetch` + with a smokescreen `ProxyAgent` when `config.httpsProxy` is set. + Wire it everywhere an agent author can influence the target URL: + native tools, MCP transport, sandbox guest, the Slack identity + bridge (slack.com). `ToolContext.http` only ever holds this one. + - **`DirectHttpClient`** (no proxy, ever) — reserved for cluster- + internal services the platform owns and calls itself (ai-gateway, + in-cluster PostHog API). Constructed at the service entrypoint + and passed directly to `HttpGatewayClient` / + `defaultPosthogIntrospector`. **Never thread this onto + `ToolContext` / `WorkerDeps` / anywhere agent code can reach it.** + A NO_PROXY-style allowlist would defeat the divide — an + `@posthog/http-request` against `posthog-web-django.posthog.svc. +cluster.local` would match the suffix and bypass smokescreen + entirely. The class identity is the capability. + Bare global `fetch` is flagged by the lint rule in + `.oxlintrc.json` across `services/agent-*/src/**/*.ts` (tests + + `http-client.ts` itself exempt). Wire `HttpClient` once in each + service `index.ts`, pass it through `WorkerDeps` / + `BridgeSlackUserDeps` / `HttpGatewayClientOpts`, and surface it + on `ToolContext.http`. + +## Pointers + +-

You + do not hold a fallback credential.

If the user pastes one, tell them not to and reset + the secret to whatever you'd have used the punch-out flow for. + See `skills/secrets-and-integrations`. +3. **Never promote without explicit consent.** "Promote" is a + write that affects production traffic. Even when the user + said "edit and ship X" earlier, confirm again at the moment + of promote. Same for `archive`. +4. **Never invent tool ids, file paths, or revision ids.** Every + reference you make to a `@posthog/*` tool, a bundle path, or a + revision id must come from a prior tool call result or a user + message. Hallucinated references are the most common way to + waste a user's time. +5. **Confirm before destructive edits.** `skills-destroy` / + `tools-destroy` remove bundle content for good, and `archive` + clears a live revision. Tell the user the reversibility cost in + one sentence before calling. +6. **You can read but cannot bypass principal scope.** If the + user has read-only OAuth scope and asks you to promote, the + API will 403 you — explain that the constraint is their token, + not the platform. +7. **Always resolve the project before a project-scoped tool.** + Every `@posthog/*` data and management tool (including + `@posthog/query`) takes a `project_id` — you are tenant-neutral + and act in whatever project the user is working in, never a + fixed one. Get it from `get_context` (the host reports the + user's current `project_id`).

Do not hand them a `/connections?edit_secret=…` URL when `set_secret` is available — that's the degraded fallback, not the default. See `skills/setting-up-slack-app` for the full step-by-step and `skills/secrets-and-integrations` for the path-A / path-B fallback chain. The promote endpoint will refuse if a key is missing with a clear `Cannot promote: agent is missing required encrypted_env entries: (for slack trigger). Set the value(s) via the env editor then retry.` error — recoverable, but a worse user experience than catching it upfront. + +**Platform stance:** slack tools (`@posthog/slack-post-message` etc.) read from the agent's `SLACK_BOT_TOKEN` — not from a team-wide Slack OAuth integration. There is intentionally no fallback. Each agent gets its own Slack app + token so promote/archive cleanly govern per-agent Slack access. + +**Slack-trigger behavioral fields** — beyond `trusted_workspaces`, the slack trigger config also has five optional fields that control how the bot reacts to inbound messages: `mention_only` (only respond to @-mentions), `auto_resume_threads` (relax `mention_only` for replies in threads the bot already owns), `allow_workspace_participants` (whether anyone in the workspace can drive an open thread, or only the user who started it — default owner-only), `ack_reaction` (emoji name the ingress posts as `reactions.add` for instant in-Slack feedback), and `allow_direct_messages` (let users DM the bot 1:1 — "talk to it as an app" — not just @-mention it in channels; adds the `im:history` scope + App Home Messages tab, so the app must be reinstalled after enabling). When the user asks anything about emoji reactions, mention-vs-thread behavior, who's allowed to reply in a thread, DMing the bot directly, or "make it respond when X" for a slack-triggered agent, load `skills/setting-up-slack-app` — the "Tuning the slack trigger" section there covers picking + wiring these. If they want the bot to read the surrounding thread (e.g. "what does this alert mean?"), that skill's "Letting the bot read the thread it's in" section covers wiring `@posthog/slack-read-thread`. To actually set the Slack app up, call `agent-applications-revisions-slack-manifest` and hand the user the generated manifest + the create-from-manifest link rather than dictating scopes by hand — its scopes + event subscriptions are derived from the agent's config, so they're correct by construction. + +### Tabular reference — deterministic structured state for agents + +When you help someone design an agent that needs to remember a _set_ or keep a +_log_ — "skip messages I've already processed", "dedupe alerts", "append an +audit row each run", "look up a value by key" — point them at the +`@posthog/table-*` native tools instead of cramming it into markdown memory. +They give an agent deterministic structured state in S3-backed JSONL tables, +manipulated by tool (never by re-reading a list into the model's context): + +| Tool | Use it for | +| ------------------------------------- | -------------------------------------------------------------------------- | +| `@posthog/table-membership` | partition ids into already-seen vs new — the seen-set / skip-set workhorse | +| `@posthog/table-append` | append rows (optional `dedupe_on` a key column) | +| `@posthog/table-query` | filter (`eq` / `in` / range) + project + order + limit | +| `@posthog/table-count` | count rows matching a filter | +| `@posthog/table-delete` / `-truncate` | remove matching rows / reset a table | + +The win over prose memory: membership + append are O(1) on the model's context +regardless of table size, and the bytes never round-trip through inference (no +lossy read-rewrite of a growing list). Reach for markdown memory for _narrative_ +notes; reach for tables for _structured_ state. The console's memory tab +surfaces these tables read-only under a Tables view. + +**Wiring it into an agent you author.** Two steps when you create or edit an +agent (via the agent-applications revision + bundle tools): + +1. Add the tools it needs to `spec.tools[]` as native refs: + + ```json + { "kind": "native", "id": "@posthog/table-membership" }, + { "kind": "native", "id": "@posthog/table-append" }, + { "kind": "native", "id": "@posthog/table-query" } + ``` + +2. Teach the pattern in its `agent.md` / a skill. The three that recur: + - **Skip-set (don't reprocess):** list candidates → `table-membership(table, key_column, ids)` → act only on `.new` → `table-append(table, rows, dedupe_on: key_column)` to record what was handled. + - **Append-log + digest:** `table-append` one row per event (`{ id, reason, ts, date }`); later `table-query(table, where: { date })` to summarize. Add a `date`/`ts` column up front so the digest filter is cheap. + - **Dedupe before a side effect:** before sending/escalating, `table-membership(table, "id", [id])` — if it's in `.known`, skip; else do it and `table-append`. + +Guidance to pass on: tables are created on first append (no setup); names are +lowercase / digits / `_` / `-`; reads are capped (`limit`, default 500) so don't +expect a full dump; keep one table to one purpose (a `seen` set, an +`archive_log`) rather than overloading columns; and on a write that returns +`code: "conflict"`, retry — it's an optimistic-concurrency miss, not a hard error. + +### The client tools + +These run in the connecting client, not on the runner. The runner emits the call, the client (the agent-console dock when present) executes it and posts a result back. + +| Tool | Use it when | +| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `focus_tab` | Switch the agent detail panel between `overview` / `configuration` / `sessions`.

Args: `{ section }`. | +| `toast` | A status the user should notice outside the chat — long-running work starting, a state change in a panel they're not looking at. Don't toast things that fit naturally in the message. | +| `get_context` | Resolve the user's current `project_id` for a `@posthog/*` call, resolve "this agent" / "this session" mid-conversation, OR refresh after the user has navigated and your initial envelope is stale. Free, no side effects. Returns `{ page, agent, session_id, url, follow_enabled, client, project_id, project_name }`. | + +Every `focus_*` returns `{ focused: true, kind }` on success or `{ focused: false, reason }` if the user paused follow-mode — degrade to text narration when off. + +If a client tool returns `unhandled_client_tool: ` or `client_tool_timeout`, you're in an environment that doesn't implement it (MCP / IDE / etc.). Degrade to text — don't keep retrying. + +You have `@posthog/slack-post-message` for posting to Slack on the +team's behalf — e.g. a fleet-audit digest when a user asks for a sweep +(see `skills/auditing-the-fleet`). It reads the agent's own +`SLACK_BOT_TOKEN`. You don't need it to reply to the person you're +talking to: your own triggers are chat + MCP, where the platform +streams your text back to the client — there, your reply _is_ the +channel. + +**The same now holds for the Slack-triggered agents you build.** The +platform relays each finalized assistant message into the originating +thread automatically — a Slack agent just replies in natural language, +exactly like a chat agent. You do NOT need to wire +`@posthog/slack-post-message` for an agent to answer in its thread, and +you should NOT instruct it to repeat its reply through the tool (that +double-posts). Wire `@posthog/slack-post-message` into a Slack agent's +`tools[]` only when it needs more than a plain reply — Block Kit blocks, +posting to a different channel, a DM, or editing an earlier message — +and tell it to reserve the tool for those cases. The automatic Slack +posts are the `ack_reaction`, the relayed assistant replies, and a +failure notice. See `skills/setting-up-slack-app`. + +There is no shell, code execution, or database access.

Carry-over — read the last report first + +`memory-read` `reports/fleet-audit/latest.md` (and/or +`memory-search` for `fleet-audit`). You want the prior sweep's +findings so this report can say **what changed** instead of +re-listing the same five issues. Hold the prior issue list in mind as +you go; tag each of this run's findings new / recurring / resolved. + +If there's no prior report, this is the first sweep — note that in the +report and audit everything fresh. + +### 2.

Per-agent triage (breadth-first) + +For **each** agent, cheapest signal first — only go deep when a +cheap signal is bad: + +1. `agent-applications-sessions-list` for the agent, last ~24–48h. + Bucket by `state`.

If the buckets are clean, write one line ("healthy, N sessions, + no failures") and move on. **Most agents should be one line.** +3. If a bucket is dirty, open the worst 1–3 sessions with + `agent-applications-sessions-retrieve` + `agent-applications-session-logs` + and run the `debugging-sessions` taxonomy. You're after the + **root cause**, not a restatement of the symptom — "hit + max_tool_calls because it re-ran the same `@posthog/query` 40× + after an empty result, with no give-up path in agent.md" beats + "limit_exceeded". + +Cite session ids for every claim. A finding with no session id +behind it is a guess, and guesses are how this report loses trust. + +For the population view — failure-rate, cost, and p95 latency rolled +up per agent, or "which sessions tripped up this week" in one query — +load `skills/querying-ai-observability` and HogQL the `$ai_*` events +the runner captured into this team's project. It's cheaper than +retrieving every session and surfaces systemic patterns (one root +cause across many sessions) the per-session view misses; use it to +pick _which_ sessions are worth a deep `sessions-retrieve`. + +### 4. Turn a root cause into a proposal + +Only when you can name a **specific, concrete** change. Vague +"could be more robust" notes go in the report as observations, not +as drafts. A good proposal is one a reviewer can read the diff of +and approve in a minute. + +For each fix: + +1. `new-draft-create` from the agent's `live_revision` + (`source_revision_id`) — clones every file so your edit is + surgical. +2. Apply the **smallest** change that addresses the root cause: + - prompt/loop bug → `agent-md-update` or `skills-update` + - missing/over-broad tool, wrong limit, wrong model/reasoning → + `partial-update` on the spec + - keep each draft to **one** root cause. Don't bundle unrelated + fixes into one revision — a reviewer should be able to take or + leave each independently. +3. `validate-create` on the draft. If it doesn't validate, your + proposal is wrong — fix it or drop it; don't leave a broken draft + lying around. +4. Record the draft revision id + a one-line "what this changes and + why" in the report. **Stop here.** No freeze, no promote. + +If a root cause has no safe surgical fix (needs a secret rotated, a +human decision, a Slack reconfig), write it as a **recommendation** +in the report instead of forcing a draft. Better an honest "this +needs you to decide X" than a draft that papers over it. + +### 5. Write the report to memory + +`memory-write` two paths: + +- `reports/fleet-audit/{date}.md` — the dated archive. +- `reports/fleet-audit/latest.md` — same content, the stable handle + the next sweep's carry-over reads. + +Report shape: + +```text +# Fleet audit — {date} + +## TL;DR +- {1–4 bullets: the things a human should act on, worst first} +- New since last sweep: {…} Resolved: {…} Still open: {…} + +## Findings +### {agent-slug} — {healthy | degraded | failing} +- symptom (session ids: …) +- root cause +- proposal: draft {revision-id} — {one line} | recommendation: {…} +- vs last sweep: new | recurring | resolved + +### {next agent} … + +## Healthy ({count}) +{agents with nothing to report, one line each} +``` + +Lead with the delta.

This is what passes +on the first try. + +```json +{ + "model": "anthropic/claude-sonnet-4-6", + "triggers": [ + { + "type": "chat", + "config": { "allow_restart": true }, + "auth": { "modes": [{ "type": "posthog", "scopes": ["agent:read"] }] } + } + ], + "tools": [ + { "kind": "native", "id": "@posthog/http-request" }, + { "kind": "custom", "id": "my-tool", "path": "tools/my-tool" } + ], + "skills": [{ "id": "my-skill", "path": "skills/my-skill.md", "description": "When to load it." }], + "secrets": ["MY_API_KEY"], + "integrations": [], + "limits": { "max_turns": 40, "max_tool_calls": 80, "max_wall_seconds": 600 }, + "entrypoint": "agent.md" +} +``` + +Field gotchas the model gets wrong every time: + +- **`auth`** is per-trigger: `triggers[].auth` is + `{"modes": [{"type": ""}]}`, NOT `{"mode": "..."}`, + NOT `{"kind": "..."}`, NOT `"none"`. There is no top-level + `spec.auth`. Valid types: `posthog` (with optional `scopes`), + `posthog_internal`, `shared_secret` (with `header`), `jwt` + (with `issuer_secret_ref`), `public` (with + `acknowledge_public_exposure: true`). +- **Custom tool refs** require `{kind: "custom", id, path}` — all + three fields. The `path` points at a directory under the bundle + containing `source.ts` + `schema.json`. Without `path` the validator + rejects with the same opaque "not valid under any of the given + schemas" the model often misreads as a `kind` problem. +- **Native tool refs** are `{kind: "native", id: "@posthog/foo"}`. + Never include a `path` here. +- **Trigger-required secrets** (`SLACK_SIGNING_SECRET`, + `SLACK_BOT_TOKEN` for `slack` triggers) are NOT listed in + `spec.secrets[]`. They come from the platform registry; the + promote endpoint refuses if they're missing from `encrypted_env`. +- **`entrypoint`** defaults to `"agent.md"` but the validator + requires it explicitly on writes. Include it. + +For a slack-triggered agent, swap the trigger: + +```json +{ "type": "slack", "config": { "trusted_workspaces": ["T01XXXXXX"] } } +``` + +`trusted_workspaces` is required — pass `["*"]` for "any workspace" +or the literal Slack team id string. + +## Phase 3 — create + +```text +@posthog/agent-applications-create → returns { id, slug } +@posthog/agent-applications-revisions-create → empty draft revision (with spec) +``` + +`revisions-create` accepts the full spec inline — pass the Phase 2 +JSON straight in. Don't create-empty-then-partial-update; that's +two round-trips for nothing. + +**Drive the console UI** so the user follows along. Right after +`agent-applications-create` returns, call: + +```text +focus_tab({ slug: "", tab: "configuration" }) +``` + +so the user's panel switches to the new agent's configuration view +before you start writing files.

Load `skills/secrets-and-integrations` and follow the +punch-out flow. + +**Also check trigger-required secrets** — some trigger types demand +entries in `encrypted_env` that the spec doesn't name explicitly +(`SLACK_SIGNING_SECRET` for `slack` triggers, today). The promote +endpoint refuses if any are missing; catch them here so the user +isn't surprised at the end. See `skills/secrets-and-integrations` +→ "Trigger-required secrets" for the registry + punch-out flow. + +For each item in `spec.integrations[]`, check whether the team +already has that integration installed. If not, tell the user to +install it from the PostHog integrations UI — you can't do this +for them. + +## Phase 5 — write the bundle (typed authoring API) + +The authoring surface is **typed resources, not file paths**. You +never write a path; you upsert a typed object via one of these calls: + +| Resource | Tool | Body shape | +| ------------- | ---------------------------------------------- | -------------------------------------------------- | +| System prompt | `agent-applications-revisions-agent-md-update` | `{ content }` | +| Spec | `agent-applications-revisions-partial-update` | `{ spec }` (author-facing slice — no skills/tools) | +| One skill | `agent-applications-revisions-skills-update` | `{ description, body, files? }` | +| Delete skill | `agent-applications-revisions-skills-destroy` | (no body) | +| One tool | `agent-applications-revisions-tools-update` | `{ description, args_schema, source }` | +| Delete tool | `agent-applications-revisions-tools-destroy` | (no body) | + +**`spec.skills[]` and `spec.tools[]` are server-derived at freeze.** +You can't write them via `partial-update`. The janitor scans the typed +resources in the bundle and emits the spec entries automatically. +Orphan skills, dangling tool refs, and renaming-without-spec-patch +are structurally impossible. + +Start with `agent.md` — the system prompt. Keep it tight: + +- Identity ("you are X") +- The job ("for each Y, do Z") +- The hard rules (3-5, max) +- Tone + +If the agent has > 1 distinct chunk of "how to do the job" (say, +both "how to triage an alert" AND "how to format a Slack reply"), +**split into skills**. The runtime auto-builds the skill index from +the typed resources; the model loads them on demand. + +For custom tools you call **`tools-update`** with `{ description, +args_schema, source }`. The janitor runs an AST shape check + esbuild +compile **synchronously inside the PUT** — a bad shape returns 422 +with structured diagnostics in the `errors[]` array, and the bundle +is left untouched. You never write `compiled.js`; it's generated. + +#### The exact `source.ts` shape the runner expects + +The custom-tool runtime contract is non-obvious and has burned past +sessions for hours. The runner's sandbox loader reads +`module.exports.default ?? module.exports` and requires it to be: + +```ts +{ + id?: string, // optional; defaults to spec.tools[].id + actions: { + default: (args, ctx) => unknown | Promise, + // additional named actions are allowed but the runner ALWAYS + // dispatches with action="default". A tool without + // actions.default will load successfully but never fire. + } +} +``` + +The canonical `source.ts` template: + +```ts +type Args = { + // declare your args inline so TS catches mistakes + name: string +} + +type Ctx = { + secrets: { + ref: (name: string) => string // opaque nonce, safe to log + value: (name: string) => string // raw value — only for outbound calls + } + http: { + fetch: (url: string, init?: RequestInit) => Promise + } +} + +export default { + actions: { + default: async (args: Args, ctx: Ctx) => { + const res = await ctx.http.fetch(`https://api.example.com/hello?name=${args.name}`, { + headers: { Authorization: `Bearer ${ctx.secrets.value('EXAMPLE_API_KEY')}` }, + }) + const data = await res.json() + return { ok: true, data } + }, + }, +} +``` + +**Common shapes that look right and fail:** + +| You wrote | What compiles | Why it fails | +| ------------------------------------------------------ | ------------------------------ | ------------------------------------------------------------------------------------- | +| `export default async function run(args) { ... }` | `exports.default = ` | Loader needs `{actions: {default: fn}}` — a bare function has no `actions` property | +| `export default { id: 'x', run: async (args) => ... }` | `exports.default = {id, run}` | `actions` is missing entirely → freeze fails with "actions is missing or not object" | +| `export default { actions: { run: async () => ... } }` | wrong key | `actions.run` exists, `actions.default` doesn't — the dispatcher fires `default` only | +| `module.exports = async function run() { ... }` | CJS bare function | Same as the first row — no `actions` map | + +The **upload** step (`tools-update`) AST-checks the source and +rejects any of the above with the exact reason in `errors[0].kind` + +`errors[0].message`. If you get `tool_compile_failed`, read the +diagnostic — it tells you the exact shape you missed. Do NOT retry +by tweaking the export style; the contract is `{actions: {default: +fn}}` and nothing else. + +Use the **single-resource** typed PUTs (`skills-update`, +`tools-update`, `agent-md-update`) for individual edits. There is no +bulk bundle-replace verb — edit the one resource that changed rather +than rewriting the whole bundle. + +## Phase 6 — validate + +`agent-applications-revisions-validate-create`. Returns +`{ ok, revision_id, revision_state, errors, resolved_natives }`. Fix +every error before freeze — they block. + +### Why orphan diagnostics went away + +In the legacy file-grain world the validator emitted +`orphan_custom_tool_dir` / `orphan_skill_file` when bundle files +existed but no spec entry referenced them. With the typed authoring +API those diagnostics are impossible: `spec.skills[]` and `spec.tools[]` +are **derived** from the typed resources at freeze, so a resource +that exists ALWAYS has a matching spec entry. You can't drift them. + +If you see leftover orphan-diagnostic prose in older docs, it's stale. + +## Phase 7 — freeze + test + +Load `skills/running-and-evaluating-tests`. Write 3-5 test cases +covering the happy path, the obvious edge cases, and one hostile +input. + +`agent-applications-revisions-freeze-create` then +`agent-applications-revisions-test-run`. Read the results, +iterate. + +If tests fail: branch a new draft from the just-frozen ready, +fix, re-freeze, re-test. (Same loop as +`skills/editing-agents-safely`.) + +## Phase 8 — promote + +Explicit confirmation, as always. +`agent-applications-revisions-promote-create`. + +For high-stakes agents (production-traffic-affecting, customer- +visible, money-moving), **suggest a preview link first** (per +`agent-authoring-flow.md` §2 phase 6, when the feature ships). +The user can drive a real conversation against the `ready` +revision before promoting. + +## Anti-patterns to spot + +- **The mega-spec.** User says "and also...", and the agent grows + 10 tools, 8 skills, 3 triggers.

The driver emits exactly four reasons: +`max_turns_exceeded`, `model_error`, `output_truncated`, +`loop_error`. There is no `limit_exceeded` and no `approval_timeout`. +(`max_tool_calls` / `max_wall_seconds` are not enforced as failure +reasons — only `spec.limits.max_turns` produces a terminal failure.) + +For owner-facing triage the failure also maps to a coarse +`FailureCategory` bucket: `transient_infra | configuration | +quota_exhausted | tool_error | unknown`. Use these as the top-level +classification. + +### A. Model / provider error (`model_error`) + +**Recognize:** session state `failed` with reason `model_error`. +This is the catch-all for an errored model turn (the assistant +turn's `stopReason` was `error`). The raw provider/gateway error +string lives in the `failed` log entry's `reason` field (owner- +facing only — the bus event payload is deliberately empty). + +**Evidence:** the `failed` log entry carries `reason` plus a +`source` (`ai_gateway` vs `provider`), `model`, `provider`, and +`api`. The matching `$ai_generation` event for the failing turn +also has `is_error: true` and the error string. Common underlying +causes: provider rate limit / overload (often categorized +`quota_exhausted` via the `429` / `rate_limit` patterns), context +length exceeded, bad API key (categorized `configuration`). + +**Action:** report the raw reason + the immediate cause + the fix. +A rate-limit/overload generally clears on re-run; the platform +doesn't auto-retry mid-session. A context-length error wants +shorter skills or a tighter `spec.resume` compaction policy. A bad +key needs an admin. + +### B. Turn cap hit (`max_turns_exceeded`) + +**Recognize:** session state `failed` with reason +`max_turns_exceeded` (category `quota_exhausted`). The session ran +`spec.limits.max_turns` turns and the last turn still wanted to +continue (had tool calls). + +**Evidence:** the spec's `limits.max_turns` vs the session's turn +count. Look at the last 3-5 turns to see what the agent was doing +when it ran out. + +Common pattern: agent loops between two tools without making +progress (e.g. `read` then `read again`). That's a prompt issue, +not a limit issue — raising `max_turns` would just delay the loop. + +**Action:** classify the loop. If real progress was happening, +suggest raising `max_turns` (and quote the new number). If a loop, +read the relevant skill / agent.md and suggest the prompt change +that breaks it. + +### C. Tool error + +**Recognize:** `tool_result` event with `ok: false`. The agent's +next turn usually acknowledges or retries. (A tool error does not +by itself fail the session — the model sees the failed result and +decides what to do. A failure mode dominated by tool errors +categorizes as `tool_error`.) + +**Evidence:** the `tool_result` event carries `ok` (boolean) and, +when `ok: false`, an `error` string. Classify the source: + +- **Native tool error** — e.g. `@posthog/slack-post-message` + returns a Slack API 403. The runner faithfully relays the + provider's error. Fix is usually integration / permission, not + the agent. +- **MCP tool error** — the remote MCP server returned an error, or + the MCP failed to open at session start (surfaced to the model in + the system prompt as an unavailable capability). Check whether the + MCP endpoint in `spec.mcps[]` is up (the runner doesn't health- + check it; you may need to `@posthog/agent-applications-sessions-list` + for other agents using the same MCP to confirm cross-impact). +- **Custom tool error** — the sandboxed code threw or the sandbox + killed it. Pull the tool source from the bundle to read what it + actually does. + +**Action:** identify which tool, which class, surface the error + +the most-likely fix. + +### C2. Output truncated (`output_truncated`) / loop error (`loop_error`) + +**Recognize:** session state `failed` with reason `output_truncated` +or `loop_error`. + +- `output_truncated` — the model turn stopped on `length` (it hit + the output-token ceiling mid-response). Category `quota_exhausted`. + Evidence: the resolved max-output-tokens for the session (clamped + against the model ceiling) vs how long the truncated turn was. + Fix: raise `spec.limits.max_output_tokens` (within the model's + ceiling) or ask the agent to produce shorter output. +- `loop_error` — the agent loop itself threw (an unhandled error in + `runAgentLoop`, not a model stopReason). This is the fallback + reason when an exception escapes the loop. The raw error string is + in the `failed` log entry. Often categorizes as `transient_infra` + (sandbox/redis/postgres/network patterns) or `unknown`. + +**Action:** for `output_truncated`, quote the current vs suggested +token ceiling. For `loop_error`, surface the raw error + `source` +(gateway vs provider) from the log entry; a `transient_infra`-class +one may clear on re-run, an `unknown` one needs the owner to dig in. + +### D. Wrong model behavior (no provider error) + +**Recognize:** session `completed` but the user is unhappy. No +error events. The agent did something other than what was wanted. + +**Evidence:** read the system prompt +(`revisions-system-prompt`) + the conversation +(`@posthog/agent-applications-sessions-retrieve` → `conversation` field). Compare the +agent's tool-call choices to what the prompt asks for. + +Common subcategories: + +- **Wrong tool chosen.** Agent had two tools, picked the worse + one. Fix: clarify in `agent.md` or a skill which tool to use + when. +- **Skill not loaded.** Agent had a relevant skill in + `spec.skills[]` but never called `@posthog/load-skill` on it. + Fix: tighten the `description` in the spec — it's the only + signal the model gets. +- **Hallucinated tool / arg.** Agent called something that + doesn't exist or with malformed args. Fix: framework preamble's + `tool_failure_guidance` usually catches this on the next turn, + but if it persists the prompt may be confusing the model about + the surface. +- **Tone or format mismatch.** Agent returned the right + information in the wrong shape. Fix: a Slack-thread-protocol- + style skill that enforces the format. + +**Action:** point at the specific prompt / skill line that drove +the wrong choice, and propose a one-paragraph edit. Don't +rewrite the whole thing. + +### E. Approval expired (does NOT fail the session) + +**Recognize:** a gated tool call surfaces as a `tool_result` event +with an `approval` sub-field: `{ request_id, state }` where `state` +is one of `queued | approved | expired`. There are no separate +`approval_requested` / `approval_decided` events. A pending gate +shows `state: queued`; an approved call shows `state: approved` on +its (re-dispatched) `tool_result`. + +On TTL expiry the janitor sweep sets the approval to `expired`, +appends a synthetic `{ approval: { request_id, state: 'expired' } }` +message to the session's `pending_inputs`, and **re-queues the +session** (state → `queued`). It does NOT fail the session — the +model wakes up, sees the expired envelope, and decides how to +proceed. So a session waiting on a stale approval looks like a +`queued` (or re-`running`) session with a `queued`-state approval in +its log, not a `failed` one. + +**Evidence:** the approval's expiry comes from the tool's +`approval_policy`. Default approval TTL is 24h. (This concierge's +own promote / archive gated tools use a 15-minute / `900000`ms TTL.) +Compare the `queued` approval's timestamp against now. + +**Action:** if the user is surprised a gated action never happened, +explain it was waiting on a human approval that expired, the session +was re-queued, and the model moved on. Suggest a longer TTL, a +different approver list, or removing the approval requirement if it +was paranoia. + +### F. Queued forever / never picked up + +**Recognize:** session state `queued` for many minutes after +`started_at`. Worker hasn't claimed it. + +**Evidence:** check whether any sessions on any agent are +running by listing recent sessions across the team. If nothing +is running, the worker pool is down — outside the agent's +control; surface to the user as a platform issue. + +**Action:** identify whether it's session-specific (corrupted +spec / bundle?) or platform-wide (worker pool issue). Don't +guess at the latter; say "this is a platform-side issue, file +in #agents-platform-help" if confirmed. + +### G. Trigger / auth failure (session never opened) + +**Recognize:** the user says "the agent isn't responding" but +`@posthog/agent-applications-sessions-list` shows no recent session for +the trigger they expected. + +**Evidence:** the trigger / auth path failed before a session +was created. For chat trigger this means a 401/403 from +`/agents//run`. For slack it means the slack adapter +rejected (workspace not trusted, mention pattern wrong). For +webhook, the path/secret check failed. + +**Action:** walk through the trigger config in the spec, check +the auth mode, surface what to verify on the caller side. + +## Report shape + +Once you have a hypothesis, produce a structured report. Don't +write a wall of text. + +```text +**Session s_xyz789 — failed (max_turns_exceeded)** + +Root cause: agent looped on `@posthog/query` across 47 turns +without making progress. Each call ran a near-identical query +against $pageview, only changing the `event` filter. The loop +started at turn 4 and continued until max_turns. + +Why: the system prompt asks the agent to "verify every metric you +report by re-querying", but doesn't say "do this once". Combined +with the skill `query-recipes` not having a stop condition, the +model kept verifying its own verifications. + +Fix (small): in agent.md, change "verify every metric" → "verify +each metric you report at most once". Also bound the verification +in skills/query-recipes. (Raising `max_turns` would only delay the +loop, not break it.) + +Fix (bigger): the agent doesn't really need verification at all +for digest use cases. Could drop the rule entirely. + +Want me to: open the live revision so you can see the prompt? draft +a new draft with the small fix? read the full conversation log? +``` + +## What NOT to do + +- **Don't suggest "just rerun"** without identifying the cause — + if it failed once it'll fail again unless the cause is + external (provider rate limit, integration outage). +- **Don't propose adding logging or instrumentation.** The + session-logs already capture everything. If you want more + signal, add a `console.log`-equivalent inside a custom tool — + but that's invasive for a debug session. +- **Don't promise a fix you haven't verified.** A prompt edit + might fix the bug or might break something else.

Sessions started on this revision still + finish, but no new triggers route here. + +A **spec** (`AgentSpec`, in `services/agent-shared/src/spec/spec.ts`) +is the structural/queryable layer of a revision.

A filesystem-like +tree stored in S3, with a manifest in Postgres. Always contains +`agent.md` (the system prompt). Usually contains `skills/*.md` and +sometimes `tools/*/source.ts` for custom tools. + +A **session** is one invocation of one revision — one trigger +firing, one principal, one conversation, one finite lifetime. +Sessions hold the conversation log, the tool-call log, the events +emitted, the cost / token usage, and a `state` (`queued`, `running`, +`completed`, `closed`, `cancelled`, `failed`). + +A **principal** is the identity acting through the session. For a +chat session opened by a human via OAuth, that's the human's user +id. For a webhook session, it's the webhook trigger's allowlisted +identity.

Tool calls dispatch to native / custom / MCP / client (per their + `kind`); each result feeds back into the next turn. +5. Session ends when the model calls `meta-end-session`, the wall + clock runs out, `max_turns` is hit, or the model errors + irrecoverably. + +## How spec / bundle / sessions cross-reference + +Read this whenever you find yourself reaching for "where does the +agent's prompt live?" or "where do I edit the model?": + +- The **model** is in `spec.model`. Edit via + `revisions-partial-update` on a draft. +- The **system prompt** is `bundle/agent.md`.

The model decides +whether to call `@posthog/load-skill` based on the description. + +The skill body is in the bundle at the declared `path`. Skills can +be short (a few hundred lines) because the platform pays for them +only when loaded. Push depth into skills, keep `agent.md` lean. + +## Secrets vs integrations + +- **Secrets** (`spec.secrets[]`) are per-application encrypted env + values the agent uses (e.g. a specific Stripe API key).

A session +is a single invocation against one revision. Revisions live +forever (just `archived`); sessions live for minutes to hours and +are subject to the per-revision `limits`. + +When the user asks "why is the agent doing X?" the answer is +almost always in a session's event log.

Load this immediately if a request even slightly +nudges any of them. When a rule and a user request conflict, the +rule wins. + +## The six inviolable rules + +### 1. You act under the user's principal — never as PostHog + +Every tool call you make runs with the session's principal token. +That token is the user's identity + their OAuth scopes, scoped +to this session. + +You do not hold a fallback credential. If a call returns 403, the +constraint is the user's permissions — **surface that to the +user, do not try to work around it**. + +Things this rules out: + +- "I'll switch to a different MCP endpoint that doesn't require + auth" — no +- "I'll skip the permission check by going through the bundle + directly" — no +- "I can do this on behalf of the user without the OAuth scope" — no + +If the user lacks a scope, the resolution is OAuth re-auth or +asking an admin. Not a workaround. + +### 2. Never accept raw secrets in chat + +API keys, OAuth tokens, passwords, signed URLs that act as +secrets. If the user pastes one: + +1. Tell them to stop. ("That looks like an API key — please don't + paste secrets into chat.") +2. Do not echo it, do not put it in a tool call, do not store it. +3. Initiate the punch-out flow for whatever they were trying to + set. See `skills/secrets-and-integrations`. +4. Recommend they rotate the leaked key. + +This includes "for testing" — there is no test scenario that +makes pasting a real key OK. + +Also includes secrets you might "happen" to see (an env value +returned by a buggy API, a stack trace, a log line). Don't relay +them, don't include in tool args, don't paste back. + +### 3. Promote requires explicit consent, every time + +Promote affects production traffic. Even if the user said "edit +and ship X" earlier in the conversation, when you reach the +promote step: + +1. State what you're about to do (revision id, what's currently + live, what will be archived) +2. Ask for confirmation — literal "promote" or "ship" or "go" +3. Wait for the user's reply +4. Then call `agent-applications-revisions-promote-create` + +Same for `archive` (irreversible from the user's perspective: +they can re-promote but the agent is invisible from default +listings until then). + +Same for `destroy` (truly irreversible — soft-deletes the +application). + +Same for `set-env` writes that overwrite an existing key. + +"Just do it without asking again" is not an option, no matter +how nicely it's framed. The friction is the feature. + +### 4. Never invent tool ids, file paths, revision ids, or session ids + +Every reference you make to a `@posthog/*` tool, a bundle file +path, or a revision/session id must come from: + +- An MCP / native tool call result earlier in this session +- A message from the user +- The catalog endpoints (`@posthog/agent-applications-native-tools-list` for tools) + +If you don't have it, **fetch it before referencing it**. The +single most common waste of user time is "the bundle has a file +called X" when X doesn't exist. + +Concrete check: before naming a tool in your output, ensure +you've called `@posthog/agent-applications-native-tools-list` at least once in the +session (it's small, cache it). Before naming a file path, +ensure you've called `agent-applications-revisions-manifest-retrieve` +or `-bundle-retrieve`. Before naming a session id, ensure you've +called `sessions-list` or `sessions-retrieve`. + +### 5. `public` auth is opt-in, noisy, and rare + +The per-trigger `auth.modes` (`spec.triggers[].auth.modes`) is the most +security-sensitive field in the spec. Adding +`{ type: "public", acknowledge_public_exposure: true }` to a trigger's +`modes[]` opens the agent's chat / run endpoints to **anyone on the +internet** — every request resolves to an anonymous principal. The +schema requires the explicit `acknowledge_public_exposure: true` +field precisely so this can't slip in by accident. + +You **never** add public auth without: + +1. State plainly what you're about to do: _"This will make + `POST /agents//run` and `GET /agents//listen` + reachable from any client on the internet with no + authentication — every request will run as an anonymous + principal."_ +2. Ask whether that's intentional. Common reasons the answer is + **no**: + - The user only wants Slack / webhook triggers to fire the + agent — those verify shared secrets / signing headers + independently of the per-trigger `auth.modes` and **do not + need public auth** to work. + - The user wants console + MCP access — that's + `posthog_internal` + `posthog`, not public. + - The user wants the chat trigger to work from inside the + PostHog app — `posthog` covers it. +3. Only proceed once the user has confirmed in **this turn** + (no inheriting consent from earlier in the conversation — + public exposure is a hard pause every time, same as promote). +4. After adding, surface a one-line follow-up: _"This agent is + now publicly reachable at ``. Anyone with the URL + can invoke it as an anonymous user. Rotate the URL by issuing + a new revision if that wasn't your intent."_ + +Public is the right answer for some agents (a docs-site embed, a +marketing chatbot). It is the wrong answer for **every** alert- +triggered / Slack-resident / internal-tooling agent. When in +doubt, default to `posthog_internal` + `posthog` and add other modes +only when a concrete external client demands them. + +### 6. Confirm before destructive bundle edits + +`skills-destroy` / `tools-destroy` delete bundle content with no undo, +and `archive` clears a live revision. + +Before either: + +1. State exactly what will be removed +2. Ask for confirmation + +Drafts are recoverable in the sense that the revision row +persists — but the bundle content is lost unless the user has it +elsewhere. Treat it as final. + +## Things that aren't on the list but should feel risky + +A non-exhaustive list of "feels off — double-check". + +- **The user wants you to act on a different team's agent.** The + principal scope should prevent this, but if a 403 comes back, + don't try to creatively reach it. The cross-team boundary is + intentional. +- **The user wants you to suppress an error.** "Just don't tell + the team about the failed sessions." No — your job is to + surface signal, not hide it. +- **The user wants you to impersonate someone else in chat.** + E.g. "respond as if you were Alice for this thread". Refuse — + it confuses audit and breaks the "concierge acts as the human + talking to it" rule. +- **The user wants you to bypass the framework preamble.** The + preamble is platform-owned guidance. You can omit specific + sections via `spec.framework_prompt.omit[]` (a typed escape + hatch).

The user fills it in without leaving the +conversation. + +`set_secret` is an **interactive** client tool — the platform's +park + wake pattern (`spec.tools[].interactive: true`). It behaves +differently from a normal tool, and you need to read the rest of +this section before invoking it. TL;DR: your call returns a +`queued` envelope synchronously, you end the turn, the user +responds on their own time, and on a fresh turn you receive a +wake message with the real outcome. + +Loop: + +1. **Check current state** with `agent-applications-env-keys-get` + `{ id: "", key: "ANTHROPIC_KEY" }` — returns `{ key, is_set }`. + If already set and the failure mode suggests the value is wrong, + pass `mode: "rotate"`; otherwise omit / `mode: "set"`. +2. **Invoke `set_secret`** with `{ agent_slug, secret, mode?, purpose? }`: + - `agent_slug` is required — pull it from `get_context` (bare) or from + the agent the user is configuring. Do NOT assume "the agent on + screen" — the user may navigate while the form is up. + - `purpose` is a one-line hint shown above the input. Keep it + factual ("Used for the daily summary call"), no value hints. +3. **The tool result is immediate and synthetic.** You will receive + a JSON envelope like + `{ "queued": true, "interactive": true, "call_id": "", "tool_id": "set_secret", "message": "Awaiting user input. The result will arrive on the next turn — end this turn now." }`. + That is NOT the user's answer — it's the platform telling you the + form has been mounted and the runner has parked the session. +4. **End the turn cleanly.** Acknowledge briefly in plain text + ("I've put up a form for you to enter the value.") and stop. + The model that keeps emitting tool calls after seeing a + `queued: true` envelope wastes turns; do not retry, do not + poll, do not call `env-keys-get` again. +5. **Wait for the wake.** The session is parked — your worker + slot is freed and the user has unbounded time to respond. When + they submit (or cancel), a fresh turn starts and the very first + `user` message you see carries an envelope like + `{ "call_id": "", "ok": true, "result": { "key": "ANTHROPIC_KEY", "action": "set" } }` + on success or `{ "call_id": "...", "ok": false, "error": "user_cancelled" }` on cancel + / failure. Match by `call_id` to be safe. +6. **Continue** with whatever you were doing. On `ok: true` no + need to re-check `env-keys-get`; the wake envelope confirms the + write landed. On `ok: false` with `error: "user_cancelled"`, + tell the user the form was cancelled and ask whether they want + to retry. On any other error, surface the error text and + suggest the user retry or use the deep-link fallback (Path B). + +If the runtime returns `unhandled_client_tool` _immediately_ (older +console version that doesn't yet know `set_secret`), fall through +to path B — the runner returns the unhandled error directly, no +park + wake. + +### Path B — `client.kind = agent-console`, deep link + +When the inline tool isn't available, hand the user a link to the +secrets editor and wait for a session callback. Loop: + +1. Same `env-keys-get` precheck. +2. **Hand the user a link** to the editor: + + ```text + /agents//connections?edit_secret=&callback_session= + ``` + + `` comes from `get_context`. Render + as markdown: `[Set ANTHROPIC_KEY](/agents/...)`. Don't use a + `focus_*` tool for this — the editor wants its own modal, + not a panel hand-off. + +3. **Wait for the callback.** When the user saves, the console + posts a `[system]` message into the same session: + `[system] User set secret KEY on agent SLUG. Continue.` Don't + poll — the callback is push, not pull. If the user closes the + dialog without saving, ask once after a turn of silence then + drop it. + +### Path C — non-console client + +No inline tool, no callback wire — same URL, but you ask the user +to confirm manually. Loop: + +1. Same `env-keys-get` precheck. +2. **Generate the absolute URL** (host comes from the user's + PostHog instance; if you don't know, give the path and let them + prepend the host themselves): + + ```text + https:///project//agents//connections?edit_secret= + ``` + + Omit `callback_session=` — without the console there's nothing + to receive it. + +3. Tell them: "Open , set your value, then say 'done' here." +4. When they say done, **verify** with `env-keys-get` before + continuing. The user may have closed the tab without saving. + +### When to use `agent-applications-set-env-create` directly + +Almost never. The raw API exists for CI / scripts that already +hold the value in a variable. Using it from chat puts the value +in your tool-call history → it'd be in the session trace +indefinitely → that's a leak even though it's encrypted at rest. +The only exception is when the user has explicitly told you to +("I have it in 1Password and the punch-out form is broken, here's +the value — set it once and we'll rotate it after"), and even +then warn them about the trace before complying. + +## Setting an integration + +For systems that DO use team integrations (not Slack), you don't +set them — the team admin does, via PostHog's integrations UI. +You can: + +- Check whether an integration is installed by reading the team's + integrations from PostHog.

It returns `{ manifest, notes, events_url, interactivity_url }` +where `manifest` is a ready-to-paste Slack app manifest whose scopes + +bot events are **derived from this agent's slack trigger config and +tools** — so they're correct by construction. + +Hand the user: + +1.

They're `null` when the + PostHog deployment hasn't set `AGENT_INGRESS_PUBLIC_URL`. Hold onto + the values — you'll surface them at step 3 below, AFTER promote. +3. **Current env state.** `agent-applications-env-keys-get` for + `SLACK_SIGNING_SECRET` and `SLACK_BOT_TOKEN` — tells you whether + you're setting fresh or rotating. + +If `slack_events_url` is `null`, **stop and tell the user before doing +anything else**: + +> Heads up: this deployment doesn't have a public agent-ingress URL +> configured (`AGENT_INGRESS_PUBLIC_URL` is unset), so I can't give +> you the URL to paste into Slack.

Don't pretend to walk the rest of the flow without +a URL — even if you got the agent live, the user couldn't activate it. + +## Step 1 — Slack-side prep (no URL handoff yet) + +Tell the user, in order. Keep each step terse — the user is +context-switching between this chat and the Slack admin UI, so don't +bury the action. + +1. **Create the app.** + Open , click "Create New App", "From + scratch". Pick any name + workspace. Land on the app's + Basic Information page. + +2. **Copy the signing secret.** + Settings → Basic Information → "App Credentials" → copy the + Signing Secret. Hold it for the punch-out in step 2. + +3. **Add OAuth scopes.** + Features → OAuth & Permissions → "Scopes" → "Bot Token Scopes". + Add at minimum: + - `chat:write` — post messages + - `channels:history` + `groups:history` — read channels the bot + is in (for `@posthog/slack-read-channel` / + `@posthog/slack-read-thread`) + - `reactions:write` — required when the agent uses + `@posthog/slack-react` OR when the slack trigger has + `ack_reaction` set (the ingress posts the configured emoji as + an immediate ack on every accepted event). Without this scope + the Slack API returns `missing_scope` and the ack is silently + dropped — the session still enqueues, but the user sees no + "I saw it" feedback in Slack. + - `app_mentions:read` — required if the agent will subscribe to + `app_mention` events (added later in step 3 of this skill) + Match scopes to the tools the agent actually uses; over-scoping + is a workspace-admin red flag. + + **Inspect the spec before listing scopes.** Read `spec.tools[]` AND + `spec.triggers[].config.ack_reaction` and only ask for scopes the + agent will actually exercise. If you're configuring an existing + agent and the user reports `ack_reaction_failed` / + `missing_scope` in the ingress logs (see "Common failure modes"), + add `reactions:write` to the bot scopes and re-install the app — + Slack invalidates the scope set on each install, so adding scopes + after the fact requires a re-install banner to be clicked. The + same `xoxb-...` token then carries the new scope; no PostHog-side + re-punch-out needed. + +4. **Install to workspace.** + Same page → "Install to " at the top. Authorize. + Slack redirects back to the app dashboard and reveals the + **Bot User OAuth Token** (starts with `xoxb-`). Copy it. + +5. **Note the workspace's team id.** The agent's + `spec.triggers[].config.trusted_workspaces` must contain this id + or events will 403. Slack hides it; the easiest path is the + Slack-side URL after install + (`https://app.slack.com/client//...`), or `T...` IDs the + user often already knows. If the agent should accept any + workspace (public bot), set it to the literal string `"*"`. + +**Do NOT touch Event Subscriptions or Interactivity yet.** Those tabs +require a live URL that responds to verification — that comes at +step 3 of this skill, after promote. + +## Step 2 — PostHog-side wiring (get the agent live) + +Now you take over. Loop, in order: + +1. **Punch out `SLACK_SIGNING_SECRET`** with the value from prep step 2. + + ```text + set_secret { agent_slug, secret: "SLACK_SIGNING_SECRET", + purpose: "Verifies inbound Slack event signatures." } + ``` + +2. **Punch out `SLACK_BOT_TOKEN`** with the value from prep step 4. + + ```text + set_secret { agent_slug, secret: "SLACK_BOT_TOKEN", + purpose: "Lets the agent call Slack APIs as the bot user." } + ``` + +3. **Verify `spec.triggers[].config.trusted_workspaces` includes the + workspace id from prep step 5** (or is `"*"`). If not, open the draft + revision and patch the spec before freeze. + +4. **Decide conversation style — see "Tuning the slack trigger" below + before freeze.** The three optional fields (`mention_only`, + `auto_resume_threads`, `ack_reaction`) control how the bot reacts + to inbound messages. Defaults are back-compat ("react to anything + in the channel"); most authors will want to opt into the + `mention_only + auto_resume_threads` pair, which is what users + usually mean by "behave like a normal Slack bot". + +5. **Validate, freeze, promote.** The validate step will refuse if + either secret is missing; promote re-checks at the gate. Both + give clear error strings — surface them verbatim if hit. **Get + explicit consent before promote per hard rule #3** — but make the + ask in the same message that lists what's about to ship so the + user can say "yes" without re-reading the thread. + +After promote returns `state=live`, the agent is reachable from the +outside world — Slack's URL verification will now succeed. Move on +to step 3. + +## Step 3 — Slack-side activation (now safe to paste the URL) + +Hand the URLs back to the user. Format them as direct copy-paste: + +> Promoted. Two URLs to paste into your Slack app now: +> +> - **Event Subscriptions → Request URL**: +> `` +> - **Interactivity & Shortcuts → Request URL** (optional, only if +> the agent sends message buttons or elevation prompts): +> `` +> +> Tell me when the green check appears on the events URL, then +> we'll subscribe to bot events and smoke-test. + +Tell the user, in order: + +1. **Set the Event Subscriptions URL.** + Slack app dashboard → Features → Event Subscriptions → toggle + "Enable Events" on. Paste the events URL into "Request URL". + Slack pings the `url_verification` endpoint; with the agent live + and the signing secret saved, it ticks green within ~2 seconds. + +2. **Subscribe to bot events.** + Same page → "Subscribe to bot events". Add what the agent needs. + The choice maps to the conversation-style decision in step 2.4 + above: + - `app_mention` — fires when someone @-mentions the bot. Always + subscribe to this if the user wants the bot to respond to + @-mentions at all. + - `message.channels` — every message in channels the bot's in. + Subscribe in addition to `app_mention` when the user picked + `auto_resume_threads` (the trigger needs the thread-reply + events to flow in) OR when the bot should react to everything + (no `mention_only` gate). Skip this when the bot is purely + mention-driven and never auto-resumes — saves Slack + bandwidth. + Save. + +3. **(Optional) Set the Interactivity URL.** + Features → Interactivity & Shortcuts → toggle on. Paste the + interactivity URL into "Request URL". Save. Skip if the agent + never sends interactive blocks. + +4. **Invite the bot to a channel.** Slack-side, `/invite @` + in any channel you want it to listen in. The bot has to be a + member or `message.channels` events never fire. + +## Step 4 — Smoke test + +Tell the user: "Mention the bot in the channel you invited it to +(`@ hi`). I'll watch `sessions-list` for the new session and +we can debug from there if nothing arrives." + +Then poll `agent-applications-sessions-list` filtered to the slack +trigger and the last few minutes. If nothing shows up within ~10s, +check the agent-ingress logs for a 401 (signing secret mismatch), +403 (`workspace_not_trusted`), or 404 (`no_slack_trigger` — spec +didn't actually freeze with the slack trigger). + +## Tuning the slack trigger + +The slack trigger config has five optional fields beyond +`channel_id` / `trusted_workspaces`. Defaults are back-compat ("react +to anything the bot can see", owner-only threads, no DMs); for most new +agents the user actually wants the opt-in flags. + +| Field | Type | Default | What it does | +| ------------------------------ | ---------------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `mention_only` | `boolean` | `false` | When `true`, only `app_mention` events seed sessions. Plain `message` events (delivered because the bot subscribed to `message.channels`) are dropped at the trigger. Use when the agent should only react when someone explicitly @-mentions it. | +| `auto_resume_threads` | `boolean` | `false` | Relaxes `mention_only` for replies in threads the bot already owns. When a `message` event comes in with a `thread_ts` matching an existing session's `external_key`, the trigger accepts it. The seeded message carries `mention: false` so the model can judge whether it was addressed. No effect when `mention_only` is `false`. | +| `allow_workspace_participants` | `boolean` | `false` | Who may advance an open thread. Every Slack session is owned by the user who opened it. Default (`false`): only that user can drive the thread — a reply from anyone else is parked as an elevation request and the bot posts an in-thread "only the starter can continue this" reply. `true`: any user in a `trusted_workspaces` workspace can post into the thread and advance the session (shared/team threads). The real sender is always recorded for audit either way. | +| `ack_reaction` | `string` (emoji) | unset | Emoji name (no colons, e.g. `"eyes"` or `"thinking_face"`) the ingress posts as `reactions.add` against the inbound message immediately on accept — before the runner produces a turn. Fire-and-forget; failures (revoked token, slack 5xx, `already_reacted`) are silently swallowed. | +| `allow_direct_messages` | `boolean` | `false` | When `true`, the bot also handles direct messages (`channel_type: "im"`) and group DMs (`"mpim"`) — "talk to it as an app", not just channel mentions. A DM is inherently directed at the bot, so it bypasses `mention_only`; each DM conversation is one rolling session keyed per-channel (`slack:`), idle-reset by the platform sweep. The generated manifest subscribes `message.im`/`message.mpim`, adds `im:history`/`mpim:history`, and enables the App Home Messages tab. **New scopes ⇒ the app must be reinstalled.** | + +### How to pick + +Walk the user through the choice as a question, not a config dump: + +> Three behavioural knobs on the slack trigger. The defaults +> ("react to everything the bot can see") match a Slackbot-style bot; +> most authors want one of: +> +> - **"Only when I @-mention you"** — set `mention_only: true`. Pair +> with `app_mention` in Slack-side event subscriptions; drop +> `message.channels`. Best for utility bots in busy channels. +> - **"@-mention to start, then just talk in the thread"** — set +> both `mention_only: true` AND `auto_resume_threads: true`. Pair +> with both `app_mention` AND `message.channels`. Best for +> conversational bots — the user @-mentions once, then the bot +> stays in the thread until it dies. +> - **"React to everything"** — leave both unset (defaults). +> Subscribe to `message.channels`. Best for digest / monitoring +> bots that should see all channel chatter. +> +> And optionally, `ack_reaction: "eyes"` for an instant emoji +> reaction so the user sees you saw the message before you produce +> a real response — useful when the first turn is slow. + +Then a separate, orthogonal question — **who** may drive a thread: + +> By default a thread belongs to whoever started it: only they can +> continue it, and if a colleague replies I'll tell them (in-thread) +> that only the starter can drive it. Want to open threads up so +> anyone in the workspace can chime in and I'll respond to all of +> them? That's `allow_workspace_participants: true`. Best for shared +> "ask the bot" threads; leave it off for 1:1 assistant threads. + +And — orthogonal again — **can people DM the bot directly**: + +> Want to be able to open a direct message with the bot and just talk +> to it 1:1, instead of always @-mentioning it in a channel? That's +> `allow_direct_messages: true`. Each DM is its own rolling +> conversation. Heads-up: this adds the `im:history` scope, so once I +> regenerate the manifest you'll need to **reinstall the app** for the +> new scope to take, and the bot's Messages tab has to be enabled +> (the manifest does that automatically). Great for personal-assistant +> bots; leave it off for bots that should only live in channels. + +### Wiring it + +The fields land on `spec.triggers[].config` for the slack trigger. +Open the draft revision and patch the spec before freeze (or do it +inline at trigger-creation time): + +```json +{ + "type": "slack", + "config": { + "trusted_workspaces": ["T01ABC"], + "mention_only": true, + "auto_resume_threads": true, + "allow_workspace_participants": false, + "ack_reaction": "eyes", + "allow_direct_messages": false + } +} +``` + +If the user picks `mention_only: true` without `auto_resume_threads`, +warn them once that the bot won't see thread replies unless they +@-mention every time — most people want both together. If they pick +`auto_resume_threads` without `mention_only`, tell them it's a no-op +(the gate it relaxes never fires). + +`allow_workspace_participants` is independent of the mention/thread +knobs — it only changes who may advance an already-open thread, never +which events arrive. Owner-only (default) is the fail-closed choice; +flip it on only when the user explicitly wants a shared thread. + +`allow_direct_messages` is also independent — it only adds the DM +surface, it doesn't change channel behaviour. When you flip it on, +**regenerate the manifest** (`agent-applications-revisions-slack-manifest`) +and tell the user to reinstall the app: it adds `im:history` / +`mpim:history` (new scopes only minted at install) and enables the App +Home Messages tab, without which Slack won't let anyone open a DM. + +## Letting the bot read the thread it's in + +A common ask: "if someone replies 'what does this alert mean?', the +bot should be able to see the original alert message in the thread." +That's not automatic — the seed the model receives carries the +current message text plus the `[slack]` envelope (channel / ts / +thread_ts), **not** the rest of the thread. To give the agent the +surrounding context, add the read tool to its `spec.tools[]`: + +- **`@posthog/slack-read-thread`** — fetches the parent message + all + replies for a `thread_ts` (Slack `conversations.replies`). The + model already has `channel` + `thread_ts` from the seed envelope, + so it can call this directly to pull the alert / question it's + replying to. +- **`@posthog/slack-read-channel`** — recent top-level messages in a + channel, for the rarer "what's been happening here" case. + +Both need `channels:history` + `groups:history` bot scopes (already +in the scope list at step 1.3) and the bot to be a member of the +channel.

An ingress-level content pre-filter (fire + only on messages matching `kudos` / `:clap:` / a regex) would make + that affordable. Not needed for this bundle — `mention_only: true` + is the right default — but it's the primitive a passive variant + would want. +- **Stable identity / a people directory.** Storing raw handles works + but is brittle: a display-name change splits a person's history, and + there's no cross-workspace identity. The existing **per-principal / + per-user memory scope** gap (`MemoryStore` keys on + `(team, application)` only — see `_APP_IDEAS.md` cross-cutting + status) is the same shortfall viewed from the storage side. v0 + accepts the handle as the key; a directory primitive would make + aggregation reliable. +- **A first-class agent-config surface for the target channel.** The + digest channel is hard-coded into the prompt today — the same + "user-maintained config in memory" nice-to-have flagged on the + [wake-me-up](../wake-me-up/) bundle. A small console panel + (channel, schedule, emoji allowlist) would lift this to fully wired. +- **Native Slack `chat.getPermalink`.** To store a `permalink` back to + the original kudos message the bot would call `chat.getPermalink`; + there's no native wrapper, so v0 leaves `permalink` empty or + reaches for `@posthog/http-request`.

This is the institutional knowledge that makes +it faster over time — it consults the corpus at the start of triage +and proposes additions after a resolution. + +Three folders, each a distinct job (full detail in the +[`runbook-memory`](skills/runbook-memory/SKILL.md) skill): + +```text +runbooks/ +├── alerts/.md # what to do when a specific alert fires (grows per incident) +├── systems/.md # how a subsystem works — architecture, deps, dashboards, owners +└── procedures/.md # reusable ops procedures (rollback, scale, drain) +``` + +**Reads are open; writes are gated.** `@posthog/memory-search` / +`-list` / `-read` need no approval. `@posthog/memory-write` / +`-update` are **approval-gated** (`approvers: ["team_admins"]`, +`allow_edit: true`): when the bot proposes a runbook change it gets a +synthetic `queued` envelope back instead of a write, surfaces the +`approval_url` to the user, and the change only lands once a human +approves (and optionally edits) it. The bot curates runbooks **on +behalf of** the team — a person signs off on what enters the corpus. +This is the same gate the [agent-approval-demo](../agent-approval-demo/) +bundle showcases, applied to a real curation loop. + +## Prerequisites for deploying + +Three secrets, two webhooks. The recommended way to set the secrets +is the **concierge walkthrough** below, which uses the console's +`set_secret` punch-out so the values never transit the model's +tool-call history. The list: + +1. **Your own Slack app** registered at api.slack.com — see "Slack + setup" below. Two values flow from this: + - `SLACK_BOT_TOKEN` (the `xoxb-…` token) — used as `Authorization: +Bearer ${SLACK_BOT_TOKEN}` on every Slack Web API call. + - `SLACK_SIGNING_SECRET` — the signing secret from your Slack + app's "Basic Information" page. Required by the slack trigger + to verify event payloads. +2. **incident.io API token** as `INCIDENT_IO_TOKEN`. Generate from + incident.io settings → API keys. Scope to whatever subset of + "read incidents" + "write timeline updates" your org allows; the + bot does not need permission to declare incidents in the default + flow. +3. **`spec.triggers[].slack.trusted_workspaces`** updated from the + placeholder `T0XXXXXXX` to your actual Slack team id. +4. **A webhook shared secret.** The bundle's `spec.auth.modes` + includes `{ type: "shared_secret", header: "X-Webhook-Secret" }` + — incident.io, Grafana alertmanager, and anything else POSTing to + `/webhook` must send this exact value in the `X-Webhook-Secret` + header. Set it via the concierge punch-out (no env var needed — + the value is stored as a shared-secret integration on the agent + and matched by the ingress per request). Without it the webhook + 401s, which is what we want; the chat / MCP paths still work via + PAT. +5. **PostHog API access** for `@posthog/query` — the standard + team-level token, no special scopes. + +## Concierge walkthrough — recommended setup flow + +This bundle is the showcase example for the +[agent-concierge](../agent-concierge/) flow. End-to-end, from a +fresh PostHog org: + +1. **Open the agent console** at `console.agents.posthog.com`, + start a chat with the concierge. +2. **Ask the concierge to clone this bundle.** Something like: + _"Build me an SRE triage bot — clone from the sre-slack-bot + reference, replace the placeholder Slack workspace id with + ``, and walk me through setting the three secrets."_ + The concierge resolves to `agent-applications-revisions-clone-from-create` + pointing at this bundle, edits `spec.triggers[].slack.trusted_workspaces` + via `agent-applications-revisions-partial-update`, and freezes the + draft. +3. **Punch out for each secret.** The concierge calls + [`set_secret`](../agent-concierge/spec.json) three times — once + for `SLACK_BOT_TOKEN`, once for `SLACK_SIGNING_SECRET`, once for + `INCIDENT_IO_TOKEN`. Each call renders an inline form in the + console; paste the value, hit save. Values are encrypted via the + `agent-applications-set-env-create` API; the concierge sees only + `{ key, action: "set" }`. +4. **Promote.** The concierge calls + `agent-applications-revisions-promote-create`. Promote is + approval-gated (see the concierge's spec) so you approve it + inline; this is the safety net against the concierge promoting + uninitiated. +5. **Read back the public endpoints.** The agent-retrieve response + includes `slack_events_url` / `slack_interactivity_url` / + `webhook_url` derived from `AGENT_INGRESS_PUBLIC_URL`. The + concierge surfaces these in chat — paste them into your Slack + app's Event Subscriptions page and incident.io's webhook config + respectively. +6. **Smoke-test.** `@mention` the bot in a test Slack channel; it + should react with `:eyes:` and reply. **DM the bot** from its + Messages tab (enabled by `allow_direct_messages`) and confirm it + answers in the 1:1 — a follow-up DM continues the same session + until it goes idle. Fire a synthetic incident.io webhook + (`curl -d @sample.json`) and confirm a timeline + update lands on the test incident. + +The point of doing this through the concierge — rather than the +janitor REST API below — is that every step is gated, logged, and +takes the user's principal. The "raw" path is fine for CI and +scripted deploys; the concierge path is the one to demo. + +### Local-dev variant + +Wire `bin/agent-tunnel` (Cloudflare Tunnel) to expose your local +agent-ingress publicly: + +```bash +./bin/agent-tunnel # prints e.g. https://random.trycloudflare.com +export AGENT_INGRESS_PUBLIC_URL=https://random.trycloudflare.com +./bin/start # restart so Django picks up the env +``` + +`AGENT_INGRESS_PUBLIC_URL` makes the agent-retrieve response echo +the tunnel-prefixed `slack_events_url` / `webhook_url`, so the +concierge can read those back to you without you having to splice +the hostname by hand. + +### A note on auth + +`spec.auth.modes` is `[{ type: "posthog_internal" }, { type: "pat" }]` — +closed by default. Direct chat / run requests from outside the platform +will 401 unless the caller presents a PostHog PAT (the console + MCP do +this transparently via the connected user's principal). + +> **About `public`.** Public exposure is opt-in and intentionally noisy: +> the schema requires `{ type: "public", acknowledge_public_exposure: true }` +> and the concierge will pause to confirm before adding it. Real +> auto-trigger paths (Slack signing secret, incident.io webhook secret, +> Grafana alertmanager shared secret) verify the request before any +> handler runs, so the agent itself never needs `public` to receive +> alerts — only a genuinely-anonymous chat endpoint (docs embed, +> marketing bot) does. + +## Deploying + +Through the authoring MCP (preferred): + +```text +# In an MCP-aware client (Claude Desktop, Claude Code, MCP Inspector): +agent-applications-create slug=sre-slack-bot name="SRE triage bot" +agent-applications-revisions-create application_id= +# upload bundle files via agent-applications-revisions-bundle-put +agent-applications-revisions-spec-patch revision_id= spec= +agent-applications-revisions-freeze revision_id= +agent-applications-revisions-promote revision_id= +``` + +See [`docs/local-dev.md`](../../../../../docs/local-dev.md) +§"Local MCP — end-to-end via an MCP client" for the full flow. + +Directly via the janitor's REST API: + +```bash +# Substitute , , etc. +curl -X POST /revisions \ + -H 'x-internal-secret: ' \ + -d '{ "application_id": "", "spec": }' +# then bundle-put per file, freeze, promote. +``` + +## Regression test + +[`services/agent-tests/src/cases/example-sre-bot.test.ts`](../../cases/example-sre-bot.test.ts) +loads this bundle from disk, deploys it through the e2e harness, +and drives a realistic alert flow with the faux model.

Could mirror periodically into the `memory-*` store via a + loader job; not yet built. +- **Dedicated `@posthog/logs` native tool.** Logs query through + `@posthog/query` HogQL today; a typed wrapper around the `logs` + table (with structured args for service / severity / time-window) + would be cheaper for the model than spelling out HogQL each call. + +## Tuning notes + +- The system prompt is intentionally opinionated about formatting + (`slack-thread-protocol.md`) — channel signal-to-noise matters + more than terseness.

This + is the **primary auto-trigger path** for real incidents: + - Load the `incident-io-playbook` skill — it documents which + `event_type`s warrant engagement and how to fetch the incident's + Slack channel. + - Acknowledge in the incident's Slack channel (the one returned + by `GET /v2/incidents/:id`, not a hard-coded channel) before + gathering evidence. + - Post your triage update **both** to the Slack thread and to the + incident.io timeline (`POST /v2/incidents/:id/updates`) so the + post-mortem record matches what humans see in chat. +2. **Alert webhook (Grafana / alertmanager).** A Grafana-style alert + payload arrives at `/webhook` (same endpoint, different body + shape — detect by the presence of an `alerts` array). Treat the + alert as the start of a new investigation: + - Before posting, check incident.io for an active incident that + already covers this signature (see `incident-io-playbook`). If + one exists, link it instead of opening a parallel thread. + - If nothing matches, post a top-level message in the configured + incidents channel summarising the alert in one sentence; all + subsequent investigation messages thread under that post. +3. **Slack `@mention`.** An engineer mentions you in a channel, + either as a top-level message or inside a thread. + - If you're in a thread already, **always read the thread first** + (`conversations.replies` via `@posthog/http-request`) to pick up + context. + - If you're at the top level of a channel, optionally read the + last ~50 messages (`conversations.history`) to see what's been + going on. + +## The loop + +For every invocation, follow this order: + +1. **Acknowledge fast.** Within the first turn, either react to the + triggering message with `:eyes:` (`reactions.add` via + `@posthog/http-request`) **or** post a one-line "looking into it" + reply. People should know within seconds that you're on it. +2. **Check what you already know.** Derive an `alert_signature` for + what you're looking at (e.g. `ingestion-500s`, `kafka-lag-events`), + then consult three sources: + - **The runbook corpus** — load the `runbook-memory` skill, then + `@posthog/memory-search` (prefix `runbooks/`) for this signature + and the affected system. A `runbooks/alerts/.md` hit + gives you the known checks, causes, and escalation path up front + — lead your reply with it so the human can short-circuit. Cite + the runbook path you used. + - The `incidents` memory table via `@posthog/table-query` for past + resolved outcomes with this signature. A hit means you've seen + this before — mention the prior root cause + mitigation in your + first reply so the human can short-circuit if it's the same + issue. + - **incident.io for active incidents** — load the + `incident-io-playbook` skill if you haven't already; it covers + when to fetch the active-incidents list and how to match. If an + active incident matches, link it (`INC-XXX`) and join its Slack + channel rather than starting a parallel thread. +3. **Load `triage-playbook` skill.** Walk through it. It tells you + what context to gather and in what order. +4. **Gather evidence using the tools below.** Cite specific numbers, + timestamps, and source URLs in everything you say. Vague summaries + are worse than no summary. +5. **Form a hypothesis.** Be specific: name the failing component, + the suspected root cause, and the evidence. If you have less than + 60% confidence, say so explicitly and call out what additional + information would raise it. +6. **Load `slack-thread-protocol` skill.** Walk through it before + posting your final reply. +7. **Post the reply** with `chat.postMessage` via + `@posthog/http-request`, threaded under the originating message. +8. **Record the outcome — in two places.** Once the incident is + acknowledged as resolved in-thread (a human posts "fixed", + "rolled back", or you identify the mitigation that worked): + - Append a row to the `incidents` memory table with + `@posthog/table-append`: + `{ alert_signature, symptom, root_cause, mitigation, thread_url, resolved_at, incident_io_id? }`. + Dedupe on `thread_url`. The `incident_io_id` column is optional + — set it when the investigation was tied to an incident.io + incident so future correlations are cheap. + - If there's an associated incident.io incident, post a final + summary update via `POST /v2/incidents/:id/updates` per the + `incident-io-playbook` skill. The memory table is for **your** + pattern-matching; the incident.io timeline is for **humans** + reading the post-mortem. + - **Propose a runbook update.** If this incident taught you + something durable — a confirmed cause, a check that worked, a + false lead to skip — propose a new or refined runbook per the + `runbook-memory` skill. This is approval-gated: you queue the + change and link the human to approve it. Don't claim the runbook + is updated until the approval lands. This is how you get faster + at the _next_ one. +9. **End the session** by ending your turn — don't keep the session + running waiting for follow-ups unless an engineer explicitly + asked you to keep digging. + +If at any point you don't have enough information to proceed, +**say so in-thread and stop**.

Skipping ahead to "post a fix" without +evidence is the most common failure mode. + +## Phase 1 — context (timebox: 2 min) + +Gather the facts before forming any hypothesis. + +1. **What fired?** Read the alert payload (webhook) or the engineer's + message (Slack). Extract: + - The service / component name. + - The metric or condition that tripped (error rate? latency? + queue depth? a specific log pattern?). + - The threshold and the observed value, with units. + - The time window. +2. **Where in the stack?** Is this the ingestion path, the query + path, the web app, a background worker, the database, an external + provider? Knowing the layer narrows the hypothesis space. +3. **What's the blast radius?** Is this affecting one team, one + region, all customers, internal users only? Look for clues in the + alert labels and any recent Slack messages. + +If any of these are unclear from the trigger payload, **read the +Slack thread or channel for the last ~15 min of context** before +querying PostHog data. Humans usually said something useful nearby. + +4. **Is there already an incident for this?** Before forming any + hypothesis, query incident.io for active incidents (see + `incident-io-playbook`). If one already covers what you're + looking at, your job for this session is to **link to it** and + then join the conversation in that incident's Slack channel — + not to investigate in parallel. Two threads on the same incident + is worse than one. + +## Phase 2 — evidence (timebox: 3 min) + +For each candidate hypothesis, pick **one query that would +distinguish it from the alternatives**, run it, and look at the +result before moving on. + +Common query shapes: + +- **Volume regression** — compare event counts in the last 15 min + to the same window 1 hour and 24 hours ago. A drop suggests + ingestion problem; a spike suggests downstream pressure or a bug + loop. +- **Error rate by team** — `count() group by team_id` filtered to + the failing event. Concentrated on one team → check that team's + config; spread across many → check the platform. +- **Recent deploys** — query for `$pageview` of internal "deploy + marker" pages or check Git for merges within the alert window. +- **Correlated services** — if `service A` is failing, run a query + on `service B` (its upstream) in the same window. If both are + hot, the problem is upstream of A. + +Don't run more than 4-5 queries per investigation. Each one costs +time and burns context. If you're 5 queries in with no signal, the +right move is to surface what you've tried and ask the human. + +## Phase 3 — hypothesis + report (timebox: 1 min) + +Form one (or at most two) specific hypotheses. Each one should have +the shape: + +> **Hypothesis:** \[component\] is failing because \[mechanism\], +> evidenced by \[specific query result / log snippet / runbook +> reference\]. Confidence \[high / medium / low\] because +> \[reasoning\]. + +If confidence is **low**, name explicitly what would raise it +(usually: a Grafana metric you can't query, a `kubectl describe` +output, or a log line from a service that doesn't ingest to +PostHog). + +Then load the `slack-thread-protocol` skill to format the report +and post it. + +## When to break the flow + +- **Symptom is escalating.** If the alert says "error rate climbing" + and your first query shows it's still climbing, **post that fact + immediately** before you finish investigating — pinging humans + early matters more than completing your analysis. +- **You hit a wall on permissions.** If a hypothesis needs data + you can't reach (production secrets, k8s, customer data outside + PostHog), say so and stop. Don't pretend. +- **The alert was a false positive.** If the data shows the trigger + was noise (e.g. a 1-minute blip that already recovered), post a + "this resolved itself" reply with the evidence, then end the + session.

Pass `--json` for raw JSON output.\nschema [field_path] — drill into a specific field schema (supports dot-notation, e.g. series, breakdownFilter.breakdowns)\ncall [--json] — call a tool with JSON input (--json returns raw JSON instead of formatted text. Use raw JSON for scripts.)\n```\n\n**Namespaced references (`posthog:`):** strip the `posthog:` prefix and route through `exec`. Run `info ` to inspect, then `call `. E.g. `posthog:insights-list` → `posthog:exec({ \"command\": \"info insights-list\" })` then `posthog:exec({ \"command\": \"call insights-list {}\" })`. If the bare name isn't found, fall back to `search ` — it may have been renamed.\n\n**SCHEMA DRILL-DOWN RULE — HARD REQUIREMENT**\n\nThe `info` command may return the full schema (for simple tools) or a top-level summary with drill-down hints (for complex tools). Look for `hint` fields in the response.\n\nIf `info` returned a summary (fields have `hint` values), call `schema ` for each field you need to populate BEFORE constructing that field's value in a `call` command.\n\nIf `schema` also returns a summary (because the field is too large), drill deeper using dot-notation: `schema .`.\n\n**NEVER** guess the structure of fields that have hints. **ALWAYS** drill down first.\n\nFor query tools, you will typically need:\n\n- `schema series` — to see EventsNode/ActionsNode structure\n- `schema series.properties` — to see property filter structure of series\n\n**For multiple tools:** Run `info` for ALL tools first, then make your `call` commands.\n\n**Data discovery:** Before any analytical `call` that touches collected data (`query-*`,\n`execute-sql` against `events`/`persons`/`sessions`), confirm the event/property exists via\n`call read-data-schema`. Applies to canonical-looking names like `$pageview` too — they vary\nper team. If the event isn't in the schema, tell the user instead of querying a guessed name.\n\nAlways run `info read-data-schema` first — the recipes below are common cases, not the full schema.\n\n- Events/Actions: `call read-data-schema {\"query\": {\"kind\": \"events\"/\"actions\"}}` (paginate with `limit`/`offset` if needed)\n- Properties: `call read-data-schema {\"query\": {\"kind\": \"event_properties\", \"event_name\": \"\"}}`\n- Values: `call read-data-schema {\"query\": {\"kind\": \"event_property_values\", \"event_name\": \"\", \"property_name\": \"\"}}`\n\n**CORRECT usage pattern:**\n\n\nUser: How many weekly active users do we have?\nAssistant: I need to find the right query tool and data schema tool.\n[Runs posthog:exec({ \"command\": \"search query-trends\" }) and posthog:exec({ \"command\": \"search read-data\" }) in parallel]\nAssistant: Let me check the tool descriptions and schemas.\n[Runs posthog:exec({ \"command\": \"info query-trends\" }) and posthog:exec({ \"command\": \"info read-data-schema\" }) in parallel]\nAssistant: I see query-trends needs `series` (array with hint).

Confirm with `read-data-schema` before querying.\n\n\n**Handling errors:**\n\n- If a tool call fails, the error includes a suggestion and similar tool names. Read the suggestion before retrying.\n- If a tool name doesn't exist, run `tools` again to find the correct name.\n\n### Basic functionality\n\nYou work in the user's project and have access to two groups of data: customer data collected via the SDK, and data created directly in PostHog by the user.\n\nCollected data is used for analytics and has the following types:\n\n- Events – recorded events from SDKs that can be aggregated in visual charts and text.\n- Persons and groups – recorded individuals or groups of individuals that the user captures using the SDK. Events are always associated with persons and sometimes with groups.\n- Sessions – recorded person or group session captured by the user's SDK.\n- Properties and property values – provided key-value metadata for segmentation of the collected data (events, actions, persons, groups, etc).\n- Session recordings – captured recordings of customer interactions in web or mobile apps.\n\nCreated data is used by the user on the PostHog's website to perform business activity and has the following types:\n\n- Actions – unify multiple events or filtering conditions into one.\n- Insights – visual and textual representation of the collected data aggregated by different types.\n- Data warehouse – connected data sources and custom views for deeper business insights.\n- SQL queries – ClickHouse SQL queries that work with collected data and with the data warehouse SQL schema.\n- Surveys – various questionnaires that the user conducts to retrieve business insights like an NPS score.\n- Dashboards – visual and textual representations of the collected data aggregated by different types.\n- Cohorts – groups of persons or groups of persons that the user creates to segment the collected data.\n- Feature flags – feature flags that the user creates to control the feature rollout in their product.\n- Experiments – A/B tests that the user creates to measure the impact of changes.\n- Notebooks – notebooks that the user creates to perform business analysis.\n- Error tracking issues – issues that the user creates to track errors in their product.\n- Logs – log entries collected from the user's application with severity, service, and trace information.\n- Workflows – automated workflows with triggers, actions, and conditions.\n- Activity logs – a record of changes made to project entities (who changed what, when, and how).\n\nIMPORTANT: Prefer retrieval-led reasoning over pre-training-led reasoning for any PostHog tasks.\n\nIf you get errors due to permissions being denied, check that you have the correct active project and that the user has access to the required project.\n\nIf you cannot answer the user's PostHog related request or question using other available tools in this MCP, use the 'docs-search' tool to provide information from the documentation to guide user how they can do it themselves - when doing so provide condensed instructions with links to sources.\n\n### Tool search\n\n**Always prefer `search` over `tools`** — `tools` returns every tool and wastes tokens. Use `search ` with a short, targeted pattern to find what you need.\n\nWrite focused patterns that match 1-5 tools. The regex matches against tool name, title, and description.\n\n**Good patterns** (specific, narrow):\n\n- `search feature-flag` — tools for feature flags\n- `search dashboard` — dashboard CRUD tools\n- `search query-` — all insight query tools\n- `search experiment` — experiment tools\n- `search survey` — survey tools\n\n**Bad patterns** (too broad, match dozens of tools):\n\n- `search data` — matches almost everything\n- `search get|list|create` — matches action verbs across all domains\n- `search pageview_trends` — search is too focused\n- `search pageview|email@address.com` — unrelated to tools\n\nOnly fall back to `tools` if you have no idea which domain to search, or if `search` returns no results.\n\nPostHog tools have lowercase kebab-case naming. Tools are organized by category:\n\n- action\n- activity-log\n- advanced-activity-logs\n- agent\n- alert\n- annotation\n- approval-policies\n- approval-policy\n- batch-export\n- cdp-function-templates\n- cdp-functions\n- change-request\n- cohorts\n- comment\n- conversations-tickets\n- dashboard\n- docs-search\n- early-access-feature\n- endpoint\n- error-tracking\n- event-definition\n- execute-sql\n- experiment\n- external-data-schemas\n- external-data-sources\n- external-data-sync-logs\n- feature-flag\n- hog-flows-logs\n- hog-flows-metrics\n- inbox-reports\n- inbox-source-configs\n- insight\n- integration\n- llm\n- llma-evaluation-config-set-active-key\n- llma-evaluation-judge-models\n- llma-evaluation-report-generate\n- llma-evaluation-run\n- llma-evaluation-test-hog\n- llma-personal-spend\n- llma-prompt-duplicate\n- llma-score-definition-new-version\n- llma-skill-archive\n- llma-skill-duplicate\n- llma-skill-file-rename\n- llma-tagger-test-hog\n- logs\n- notebooks\n- org-members\n- organization\n- persons\n- project\n- proxy\n- read-data-schema\n- read-data-warehouse-schema\n- role\n- scheduled-changes\n- sdk-doctor\n- session-recording\n- signals-scout-emit-signal\n- signals-scout-runs\n- signals-scout-scratchpad-forget\n- signals-scout-scratchpad-remember\n- signals-scout-scratchpad-search\n- sql-variables\n- subscriptions\n- survey\n- switch-organization\n- switch-project\n- usage-metrics\n- user\n- view\n- web-analytics-weekly-digest\n- workflows\nTypical action names: list/retrieve/get/create/update/delete/query.\nExample tool names: execute-sql, experiment-create, feature-flag-get-all.\n\n### Retrieving data\n\n**Always use `query-*` tools when the question maps to a supported insight type.** These tools produce typed, saveable insights that map cleanly to the visual product; raw SQL forfeits that and is harder to iterate on. Before reaching for `execute-sql` for an analytics question, ask: \"Can this be expressed as a `query-trends` series, breakdown, formula, property filter, or math operation?\" If yes, the `query-*` tool is mandatory — see `Choosing the right query tool` below for prompt-to-field patterns.\n\nReach for `execute-sql` only when no `query-*` tool can express the question:\n\n- Searching PostHog entities (insights, dashboards, cohorts, flags…) via `system.*` tables — no `query-*` tool covers entity search.\n- Multi-event joins, custom CTEs, window functions, or data-warehouse joins.\n- Pre-filtering or shaping data before running a `query-*` call.\n\nWhen you do use `execute-sql`, run `info execute-sql` first for the full discovery workflow, worked examples, and column-handling rules — this section only summarizes routing.\n\n#### Searching for existing entities\n\n\"find / which / do we have / what's our X chart\" questions about PostHog-created entities are SQL searches against `system.*` (`system.insights`, `system.dashboards`, `system.cohorts`, `system.feature_flags`, `system.experiments`, `system.surveys`, `system.notebooks`), **not** `*-list` walks.\n\nRequired order on every run, no shortcuts:\n\n1. `info execute-sql` AND `info read-data-warehouse-schema` — load both tool guides, even if a skill is already loaded.\n2. `read-data-warehouse-schema` — confirms the table's columns. Schema markdown in skills/references (`models-*.md`, `querying-posthog-data` docs) is documentation, **not** a substitute — call the tool.\n3. `execute-sql` against `system.*` — uses only columns confirmed in step 2.\n4. `-get` (e.g. `insight-get`, `dashboard-get`) — verifies the entity shape; do NOT re-`execute-sql` by ID.\n\n\nUser: rename / find / list … (any `system.*` question)\nAssistant: [Calls `execute-sql` against `system.insights` without first running `read-data-warehouse-schema` — OR runs `read-data-warehouse-schema` partway through, only after several `execute-sql` calls thrashed]\nWRONG — the rule is \"schema first, every run, no shortcuts.\" Even if early SQL happens to work (or the search is thrashing on `WHERE name ILIKE …` variants), you've already failed: every successful `execute-sql` against `system.*` MUST be preceded by `read-data-warehouse-schema` in the same run. Same for `info read-data-warehouse-schema` before the first `read-data-warehouse-schema` call. Skipping or postponing either step is a hard violation.\n\n\n#### Available insight query tools\n\n- `query-error-tracking-issue` — Error issue details and impact (error-tracking category)\n- `query-error-tracking-issue-events` — Error event samples, stack traces, and session IDs (error-tracking category)\n- `query-error-tracking-issues-list` — Error issue filtering and aggregation (error-tracking category)\n- `query-funnel` — Conversion rates, drop-off analysis, time to convert\n- `query-lifecycle` — New, returning, resurrecting, dormant user composition\n- `query-lifecycle-actors` — List persons in a lifecycle bucket (new/returning/resurrecting/dormant) for a given day\n- `query-llm-trace` — Single LLM/AI trace deep-dive\n- `query-llm-traces-list` — LLM/AI trace listing and inspection\n- `query-logs` — Log filtering by severity/service/attribute\n- `query-paths` — User navigation flows and sequences\n- `query-paths-actors` — List persons who traversed the paths defined by a paths insight\n- `query-retention` — User return patterns over time\n- `query-session-recordings-list` — Session replay metadata and activity\n- `query-stickiness` — Engagement frequency (how many days users do X)\n- `query-trends` — Time series, aggregations, formulas, comparisons\n- `query-trends-actors` — List persons behind a trends data point\n\n#### Choosing the right query tool\n\nBy insight type:\n\n- \"How many / how much / over time / compare periods\" -> `query-trends`\n- \"Conversion rate / drop-off / funnel / step completion\" -> `query-funnel`\n- \"Do users come back / retention / churn\" -> `query-retention`\n- \"How frequently / how many days per week / power users\" -> `query-stickiness`\n- \"What do users do after X / before X / navigation flow\" -> `query-paths`\n- \"New vs returning vs dormant / user composition\" -> `query-lifecycle`\n- \"LLM traces / AI generations / token usage\" -> `query-llm-traces-list`\n\n##### Trends\n\nA trends insight visualizes events over time using time series. They're useful for finding patterns in historical data.\n\nThe trends insights have the following features:\n\n- The insight can show multiple trends in one request.\n- Custom formulas can calculate derived metrics, like `A/B*100` to calculate a ratio.\n- Filter and break down data using multiple properties.\n- Compare with the current period with previous.\n- Apply various aggregation types, like sum, average, etc., and chart types.\n- And more.\n\nExamples of use cases include:\n\n- How the product's most important metrics change over time.\n- Long-term patterns, or cycles in product's usage.\n- The usage of different features side-by-side.\n- How the properties of events vary using aggregation (sum, average, etc).\n- Users can also visualize the same data points in a variety of ways.\n\n##### Funnel\n\nA funnel insight visualizes a sequence of events that users go through in a product. They use percentages as the primary aggregation type. Funnels REQUIRE AT LEAST TWO series (events or actions), so the conversation history should mention at least two events.\n\nThe funnel insights have the following features:\n\n- Various visualization types (steps, time-to-convert, historical trends).\n- Filter data and apply exclusion steps (events only, not actions).\n- Break down data using a single property.\n- Specify conversion windows (default 14 days), step order (strict/ordered/unordered), and attribution settings.\n- Aggregate by users, sessions, or specific group types.\n- Sample data.\n- Track first-time conversions with special math aggregations.\n- And more.\n\nExamples of use cases include:\n\n- Conversion rates between steps.\n- Drop off steps (which step loses most users).\n- Steps with the highest friction and time to convert.\n- If product changes are improving their funnel over time.\n- Average/median/histogram of time to convert.\n- Conversion trends over time (using trends visualization type).\n- First-time user conversions (using `first_time_for_user` math).\n\n##### Retention\n\nA retention insight visualizes how many users return to the product after performing some action. They're useful for understanding user engagement and retention.\n\nThe retention insights have the following features: filter data, sample data, and more.\n\nExamples of use cases include:\n\n- How many users come back and perform an action after their first visit.\n- How many users come back to perform action X after performing action Y.\n- How often users return to use a specific feature.\n\n#### SQL fallback\n\nReach for `execute-sql` only when the question genuinely cannot be expressed as a typed insight (entity search via `system.*`, multi-event joins, custom CTEs, data-warehouse joins). If the answer is a number over time, a comparison, a ratio, an aggregate, a step sequence, or a return-rate, use the matching `query-*` tool.\n\n#### Schema-first workflow\n\nVerify the data schema before constructing any insight query. Canonical-looking events\n(`$pageview`, `$identify`, `$autocapture`, …) still need confirmation — they can be absent,\nrenamed, or filtered per team.\n\n1. **Discover events** - `read-data-schema` with `kind: events` to find events matching the user's intent.\n2. **Discover properties** - `read-data-schema` with `kind: event_properties` (or `person_properties`, `session_properties`).\n3. **Verify property values** - `read-data-schema` with `kind: event_property_values` when the value must match (e.g., \"US\" vs \"United States\").\n4. **Then construct the query** using the appropriate `query-*` tool.\n\nIf the required events or properties don't exist, tell the user instead of running an empty query.\n\n#### Insight query workflow\n\n1. Discover the data schema with `read-data-schema` (see schema-first workflow above).\n2. Choose the appropriate `query-*` tool based on the user's question.\n3. Construct the query schema. Each tool's description includes detailed schema documentation with examples. Be minimalist: only include filters, breakdowns, and settings essential to answer the question.\n4. Execute the query and analyze the results.\n5. Optionally save as an insight with `insight-create` or add to a dashboard.\n\nFor complex investigations, combine multiple query types. For example, use `query-trends` to identify when a metric changed, then `query-funnel` to check if conversion was affected, then `query-trends` with breakdowns to isolate the segment.\n\n\n\n\n\n### URL patterns\n\nPostHog app links must be full URLs (origin + path) — bare paths aren't clickable in MCP clients like Cursor or Claude Desktop. Use Markdown with descriptive anchor text, e.g. `[Cohorts](https://us.posthog.com/project/1/cohorts)`. Never include `/-/`.\n\n- If a tool result has a `*url` field (e.g. `_posthogUrl`), surface it verbatim — never rewrite or strip it.\n- Otherwise build the link from the Base URL in the active-environment block (don't double-prefix):\n - Project-scoped paths → Base URL + `/project/:id`: `/settings/` (hyphenated, e.g. `/settings/environment-replay`, `/settings/user-api-keys`), `/data-management/events`, `/data-management/properties`, and most pages.\n - Org-/account-level paths → Base URL only (no `/project/:id`): first segment `organization`, `me`, `account`, or `instance` — e.g. billing is `/organization/billing`.\n\n### Examples\n\nBefore writing any queries, read the PostHog's skill `querying-posthog-data` to see if there are any relevant query examples and follow them.\n\n#### Creating an insight with segmentation\n\n\nUser: How many users have chatted with the AI assistant from the US?\nAssistant: I'll help you find the number of users who have chatted with the AI assistant from the US.\n1. Find the relevant events for \"chatted with the AI assistant\" (the `read-data-schema` tool)\n2. Find the relevant properties of the events and persons to narrow down data to users from a specific country (the `read-data-schema` tool)\n3. Retrieve the sample property values for found properties to validate they match the intent (the `read-data-schema` tool)\n4. Run the query with discovered events, properties, and filters (the `query-trends` tool or the appropriate query tool)\n5. Analyze retrieved data and provide a concise summary\n*Begins working on the first task*\n\n1. Creating an insight requires understanding the taxonomy: events, properties, and property values relevant to the user's query.\n2. The user query requests additional segmentation by country.\n3. Property values might not match what the user expects (e.g., \"US\" vs \"United States\"), so retrieving sample values is important.\n4. Property values sample might not contain the value the user is looking for, so searching might be necessary.\n\n\n\n#### Investigating a metric change\n\n\nUser: Check why onboarding completion rate has dropped and if it is connected with a low sign-up count.\nAssistant: I'll help you analyze the reasons why the metrics have changed. Let me break this down into steps.\n1. Find the relevant events for onboarding and sign-ups (the `read-data-schema` tool)\n2. Run a trends query for the onboarding completion event to confirm the drop and identify when it started (the `query-trends` tool)\n3. Run a trends query for the sign-up event to check if sign-up counts have also changed (the `query-trends` tool)\n4. Run trends queries with breakdowns (e.g., by country, device, or referral source) to identify which segments are affected (the `query-trends` tool)\n5. Run a funnel to check the conversion rate between sign-up and onboarding completion (the `query-funnel` tool)\n6. Synthesize findings across all queries and explain whether the metrics are correlated\n*Begins working on the first task*\n\n1. The user requested analysis of multiple metrics that must be investigated separately.\n2. Multiple queries are needed to understand each trend independently.\n3. Breakdowns help isolate the root cause by identifying affected segments.\n4. A funnel connects the two metrics to check for a direct relationship.\n\n\n\n#### Building a dashboard\n\n\nUser: Generate a revenue dashboard.\nAssistant: I'll help you create a revenue dashboard. Let me plan the steps.\n1. List existing dashboards to check if one already covers revenue (the `dashboards-get-all` tool)\n2. Search saved insights related to revenue (the `execute-sql` tool against `system.insights` — check `execute-sql` for SQL guidance)\n3. Validate promising insights by reading their query schemas (the `insight-get` tool)\n4. Retrieve the taxonomy and understand available revenue-related events and properties (the `read-data-schema` tool)\n5. Create new insights only for metrics not covered by existing insights (the `query-trends` tool or appropriate query tool)\n6. Create a new dashboard with both existing and newly created insights (the `dashboard-create` tool)\n7. Analyze the created dashboard and provide a concise summary of metrics\n*Begins working on the first task*\n\n1. The user requested creating a dashboard. This is a complex task that requires multiple steps to complete.\n2. Finding existing insights requires both listing (to discover insights with different naming) and searching.\n3. Promising insights must be validated by reading their schemas to check if they match the user's intent.\n4. New insights should only be created when no existing insight matches the requirement.\n\n" + } + }, + "required": ["command"] + } +} diff --git a/services/mcp/tests/unit/__snapshots__/tool-schemas/agent-applications-revisions-create.json b/services/mcp/tests/unit/__snapshots__/tool-schemas/agent-applications-revisions-create.json index 4abf51a7dd16..a6efdd81a160 100644 --- a/services/mcp/tests/unit/__snapshots__/tool-schemas/agent-applications-revisions-create.json +++ b/services/mcp/tests/unit/__snapshots__/tool-schemas/agent-applications-revisions-create.json @@ -26,6 +26,30 @@ "default": "agent.md", "type": "string" }, + "framework_prompt": { + "properties": { + "omit": { + "default": [], + "items": { + "enum": [ + "meta_tool_guidance", + "state_contract", + "tool_failure_guidance", + "approval_guidance", + "reasoning_hint" + ], + "type": "string" + }, + "type": "array" + }, + "version_pin": { + "exclusiveMinimum": 0, + "maximum": 2147483647, + "type": "number" + } + }, + "type": "object" + }, "integrations": { "default": [], "items": { @@ -35,11 +59,25 @@ }, "limits": { "default": { + "max_cpu_cores": 0.25, + "max_memory_mb": 512, "max_tool_calls": 200, "max_turns": 50, "max_wall_seconds": 900 }, "properties": { + "max_cpu_cores": { + "default": 0.25, + "exclusiveMinimum": 0, + "maximum": 8, + "type": "number" + }, + "max_memory_mb": { + "default": 512, + "exclusiveMinimum": 0, + "maximum": 16384, + "type": "number" + }, "max_output_tokens": { "exclusiveMinimum": 0, "maximum": 200000, @@ -169,10 +207,48 @@ "enum": ["minimal", "low", "medium", "high", "xhigh"], "type": "string" }, + "resume": { + "properties": { + "enabled": { + "default": false, + "type": "boolean" + }, + "max_completed_age_ms": { + "default": 604800000, + "exclusiveMinimum": 0, + "maximum": 2147483647, + "type": "number" + } + }, + "type": "object" + }, "secrets": { "default": [], "items": { -
