Problem

  • A workflow triggered by GitHub never fires when its repository filter uses a different case than the GitHub org, for example posthog/posthog instead of PostHog/posthog.
  • GitHub treats the two names as the same repository, but the trigger's exact filter compares the strings as-is, so no run starts and nothing reports why.
  • Agents building Desktop loops write the name the user typed, and the repository lookup succeeds in either case, so nothing warns before the loop goes live.

Changes

  • A GitHub trigger now matches its repository regardless of case. The delivery's repository property is lowercased on emit, and the API lowercases the filter value on save.
  • The only visible change is that a saved repository filter reads in lowercase in the trigger editor.

How did you test this code?

Automated, run locally on this branch:

  • products/workflows/backend/test/test_github_trigger_filters.py, test_github_workflow_events.py, and the github cases in products/workflows/backend/api/test/test_hog_flow.py.
  • uv run mypy --cache-fine-grained . is clean. hogli build:openapi produced no drift.

End to end, on the local stack with GITHUB_WORKFLOW_TRIGGERS_ENABLED=true and github-workflow-triggers on:

  • I built the workflow in the editor against a fake GitHub installation with a seeded repository cache. The trigger was GitHub activity on Example-Org/Demo, event issues, "Who can start a run" = write access, followed by a webhook step to a local catcher. The saved filter came back as example-org/demo.
  • emit_github_event("issues", …) with an opened issue from a MEMBER on example-org/demo started a run. The catcher received the repository, title, body, number and sender.
  • These deliveries started no run and reached the catcher with nothing: author_association: NONE, a different repository, and a sender that is the GITHUB_APP_SLUG bot.
  • I swapped the webhook step for a Create AI task step whose instructions template the issue. The delivery created one task whose prompt carried the issue number, repository, sender, title and body. The agent sandbox run itself was not exercised locally.

Release status

  • No feature flag controls this change
  • This change is behind a feature flag and is not available to users
  • This change makes a previously flagged feature available to everyone

GitHub triggers are gated by the GITHUB_WORKFLOW_TRIGGERS_ENABLED setting (off by default) and the github-workflow-triggers flag.

Docs update

None. The trigger editor and docs already describe the repository filter; only the matching changes.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Agent: Claude Code, Fable 5.1; local verification by Claude Code, Opus 5.5 in PostHog Desktop.

  • Origin: a Desktop loop built over MCP with a lowercase repository name never fired, and the agent that built it could not tell why.
  • Skills invoked: /writing-pr-descriptions, /reviewing-with-coderabbit.
  • CodeRabbit CLI: signed out, skipped at the person's choice, so the PR opened without a local pass.
  • Bot review requested: the change touches serializer validation.
  • Duplicate check: gh pr list --search "github trigger repository" found no open PR for this.

Took a look at the diff (hog_flow.py serializer normalization, github_workflow_events.py emit, and the 0026 migration). Nothing here raises a security concern — the lowercasing is applied consistently on both the write path (serializer) and the read/emit path (delivery property), the migration only rewrites repository filter values/bytecode on rows it identifies via trigger__type="internal-event" and doesn't touch anything outside that scope, and there's no new user input reaching an unguarded sink (no SQL/command construction, no auth/permission changes). The bytecode rewrite in the migration is a plain string-constant substitution scoped to values collected from that same trigger's repository filter, so it doesn't introduce injection risk. I don't have any security findings to flag on this PR.

🤖 CI report

🚨 Trunk lane — universal lane

This PR is assigned to the universal lane. It cannot merge in parallel with other PRs, so it can take longer to merge. Ask dev-ex if you think this is wrong.

✅ Complexity (TypeScript) — clean

Cyclomatic complexity above the limit in changed typescript files (10 for production files, 15 for test files). Warn only: worth simplifying when you next touch these functions.

✅ Duplication (Python) — clean

New Python code duplication introduced by this branch. Fails at 70+ tokens in app code, or 150+ tokens when both copies live in test files. Advisory while the gate proves itself: extract a shared helper instead of copying.

✅ Duplication (TypeScript) — clean

🚨 Comment density — 21% of added code lines are comments (22 of 103)

This section warns when comments are more than 3% of the code lines a PR adds, and alerts above 6%. Before agent-assisted PRs, the typical share was about 2%. Only full-line comments count. Docstrings, generated files, snapshots, migrations, and workflow files are left out.

Comments that restate the code, record how the change came about, or narrate the next line add noise for the next reader. Keep the comments that explain a reason the code cannot show, and remove the rest. See .agents/skills/writing-code-comments/SKILL.md for the house rules.

Files with the most added comment lines:

✅ Toolbar bundle — eager 2.16 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

Retrigger

[Critical risk] Adds database migration that rewrites stored workflow trigger filters.

The PR is not safe to merge while existing case-sensitive repository regex filters can silently stop workflow runs.

📝 Walkthrough

Walkthrough

GitHub repository filter values are lowercased before validation and compilation when they use exact or is_not. Pattern and presence operators retain their original values. Emitted GitHub repository properties are lowercased, with empty values converted to None. A migration updates matching filters and bytecode constants in existing live HogFlow records in batches. Frontend full-name repository option keys are also lowercased.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to c47f1

Existing workflows combining literal and case-sensitive pattern repository filters may match incorrectly after migration, so this should be corrected before merge.

Restrict bytecode changes to the repository predicate.

When another exact property, such as title, uses the same mixed-case value as repository, this replacement also lowercases that property's bytecode literal. The persisted property remains mixed case, but the matcher executes the lowercased literal, which can produce incorrect matches.

Recompile after normalizing the repository property, or rewrite only the bytecode operand for the repository predicate. Add migration coverage for a second property that reuses the repository value.

The compiler ANDs the conditions on an event entry with the global ones, so a
repository filter written on the $github_event_received entry also decides whether
the trigger fires. Both the serializer normalizer and migration 0026 read only the
global properties, so a mixed-case value there survived and stopped matching once
the delivery property became lowercase.

The serializer now normalizes the github event entry's properties too, and the
migration walks them when it rewrites a live trigger. A sibling event entry for
another event keeps its own values.

The normalizer picked repository filters by key alone, so it rewrote a pattern the
same way it rewrote a literal. `str.lower()` is not a case transform for a regular
expression: it turns "\D" into "\d", which inverts the match set, and "(?P<name>"
into "(?p<name>", which RE2 rejects. The rewritten value is what compiles, so an
author could see a save refused over a pattern they never wrote.

Both the serializer normalizer and migration 0026 now rewrite a value only for an
operator that compares it as a literal string, treating a missing operator as exact
the way the compiler and the repository guard already do. A pattern or presence
operator keeps its value.

The API stores a repository filter lowercased, while GitHub reports `full_name` in the
owner's casing. An option keyed with GitHub's casing therefore matches no saved value, so
LemonInputSelect offers the saved repository as a custom value beside the real one and
drops that repository's rich label.

Only the qualified-name mode is lowercased. Short-name callers keep the casing they store
today, and the other qualified-name caller already lowercases these keys itself.

🦔 Hogbox preview · ❌ build failed

The preview didn't come up for commit fbc04f7. See the build log for the failing step. It'll retry on the next push.

Previews are optional and never block merging. A failure here is often a hogland or tailnet hiccup rather than anything in your PR, so the check stays green and this comment is the status.

A test run executes the staged draft's bytecode as stored, and only publish sends the draft through the serializer. A draft staged before the lowercasing change kept its mixed-case filter and bytecode, so a test run could miss a delivery that the published flow would match.

The backfill now also rewrites the draft's trigger and trigger action, guarded by draft_updated_at. The docstring now states that restoring a revision copies its content without the serializer.
