In production that is too much blast radius: a single prompt-injected agent can reach your Azure subscription, your GitHub org, and your customer data. - -kars runs agents with the same operational discipline as the rest of your services: - -- **Zero-trust agent process** — the agent runs under a different UID than the router and never sees an Azure key. The inference router holds the credential and brokers every call. -- **Cross-framework E2E mesh** — agents on different frameworks talk over AgentMesh using the Signal Protocol; the relay sees only ciphertext. **OpenClaw ↔ Hermes** is wired and exercised end-to-end on every push (`tests/e2e/interop/hermes_openclaw_bidi.sh`); the other adapters bundle the mesh client and are being brought to the same bar ([roadmap](docs/roadmap.md)). -- **Declarative operations** — fleet operations are GitOps-native and observable through the Headlamp plugin: a Kubernetes dashboard for agent sandboxes, policy CRDs, and trust topology. -- **Real Kubernetes dev loop** — `kars dev --target local-k8s` runs your agent in `kind` using the same Helm chart, NetworkPolicies, and sidecars as production AKS. - ---- - - - -## Ecosystem Alignment - -The Kubernetes agent ecosystem is evolving rapidly. Our long-term aim is to align architecturally and collaborate with upstream community efforts like `kubernetes-sigs/agent-sandbox` (for isolated pod primitives) and `agentgateway` (for edge/protocol routing). - -While no formal integrations or project discussions have taken place yet, `kars` is designed with composability in mind, so it can grow toward this broader cloud-native agentic stack as those standards mature. - -## Architecture (How it works) - -```text - ┌──────────────── Sandbox pod ────────────────┐ - User / TUI ────► │ agent container (UID 1000, no network) │ - │ │ │ - │ │ localhost only │ - │ ▼ │ - │ ┌────────────────────────────────────┐ │ - │ │ Inference Router (Rust) │ │ - │ │ │ │ - │ │ Identity (Entra Agent ID) │ │ - │ │ Content Safety (Foundry inline) │ │ - │ │ Token budget · rate limit │ │ - │ │ Tool policy · governance (AGT) │ │ - │ │ Audit (tamper-evident chain) │ │ - │ └─────────────────┬──────────────────┘ │ - │ │ │ - │ init: egress-guard │ - │ (iptables safety net: agent UID │ - │ can only reach the router locally) │ - └────────────────────┼────────────────────────┘ - │ - ┌─────────────────────┼─────────────────────────┐ - ▼ ▼ ▼ - Inference backend AgentMesh relay A2A peers -``` - -**The agent has no network of its own.** Every byte that leaves the pod leaves through the Rust inference router.

Compromise of the agent does not compromise the cloud account, the model, the audit log, or the peer mesh. - -### Spotlight: the inference router is the zero-trust core - -The per-pod router is the one component every external call passes through, and it carries most of the security model. It runs as a **separate container under a different UID (1001) than the agent (1000)**, holds the credentials the agent never sees, and is the single enforcement point for: - -- **Identity & token brokering** — exchanges the per-sandbox Entra Agent ID (or cluster Workload Identity) for backend tokens via federated OIDC / IMDS; refreshes them automatically. The agent process holds **no** long-lived key. *(`auth.rs`, `copilot_auth.rs`)* -- **Inline content safety** — reads Foundry's `prompt_filter_results` on every completion (jailbreak / indirect-attack / hate / violence / self-harm / sexual), enforces a configurable severity floor, and feeds detections into a per-peer trust penalty. *(`safety.rs`)* -- **Token budgets & rate limits** — per-tenant token ceilings and request rate limits, enforced before the call leaves the pod. *(`budget.rs`, `rate_limiter.rs`)* -- **L7 egress allowlist + blocklist** — every outbound `CONNECT` is checked against the per-sandbox allowlist and the OISD + URLhaus blocklist (daily refresh); `EgressApproval` CRDs add time-boxed exceptions. *(`forward_proxy.rs`, `egress_allowlist_loader.rs`, `blocklist.rs`)* -- **MCP gateway** — brokers calls to external MCP servers with OAuth and per-tool allowlists. *(`mcp/`)* -- **Governance (AGT)** — policy decisions, per-peer trust scoring, and behaviour monitoring through the consumed Agent Governance Toolkit primitives. *(`governance/`, `behavior_monitor.rs`)* -- **Tamper-evident audit** — every decision is written to an append-only, **SHA-256 hash-chained** audit log (AGT's `AuditLogger`: each entry's hash covers the prior entry's hash) in a stable JSONL format. *(consumed from `agentmesh::AuditLogger`; persisted via `audit_sink.rs` / `audit_jsonl.rs`)* -- **A2A data plane** — the cross-org A2A surface, including AP2 mandate signing and the trust store. *(`a2a/`)* -- **Sub-agent spawn & handoff** — creates/destroys `KarsSandbox` sub-agents and drains/migrates sessions, all through the pod's scoped ServiceAccount. *(`spawn/`, `handoff/`)* -- **Mesh bridge** — WebSocket-bridges **opaque** Signal-Protocol ciphertext to the relay. The router holds no session keys and cannot decrypt. *(`mesh.rs`)* - -**Why this is not the same as a cluster-edge gateway (e.g. `agentgateway`).** A north-south gateway governs traffic at the cluster boundary; the kars router is an **in-pod policy enforcement point** that sits on `localhost` between the agent and everything else, so the agent has **no network path that bypasses it**. They operate at different layers and are **complementary, not interchangeable** — a cluster-edge gateway can front kars, and the per-pod router still does the per-agent identity, content-safety, budget, and audit enforcement that a shared edge cannot do per-sandbox. This is the structural core of the zero-trust model: the trust boundary is the pod, not the cluster perimeter. - ---- - -## What makes it different - -- **Security teams review YAML, not Python.** Approval gates, rate limits, tool allowlists, content-safety floors, token budgets, and trust topology are declarative Kubernetes resources — commit them to a repo, reconcile with Argo / Flux, audit with `git log`. -- **End-to-End Encrypted Mesh.** Two agents that talk cannot be eavesdropped by you, by us, or by the relay.

See [Architecture → Local Kubernetes mode](docs/architecture.md#local-kubernetes-mode-kars-dev---release---target-local-k8s) and [Blueprint 02 — Local Kubernetes dev loop](docs/blueprints/02-local-k8s-dev-loop.md). - -Same CRDs.

- -On first run, `kars dev` shows a three-way provider picker — **GitHub Copilot** (default; one device-code login, no Azure account), **Azure AI Foundry / Azure OpenAI** (full feature set: Memory Store, agents, Content Safety), or **GitHub Models** (free, PAT-only, smaller context). Your choice is saved to `~/.kars/config.json` and reused on later runs; switch with `kars credentials`. Full walkthrough: **[Getting started → Launch a sandbox](docs/getting-started.md#12-launch-a-sandbox)**. - -`kars dev` then prompts for an **agent name** (default `dev-agent`). Use that name in subsequent commands: - -```bash -# Talk to the agent (TUI auto-opens; or use the CLI directly) -kars connect dev-agent -``` - -The TUI drops you into a chat window. Type *"list the files in my workspace"* or *"write a Python script that reverses a string and run it"* — every tool call the agent makes is governed by the same router code path that runs in production. - -> **Don't have an Azure AI Foundry deployment yet?** If you picked Copilot or Models above, you don't need one. If you want the full Foundry feature set, two `az` commands get you both — see **[Getting started → Choosing an inference provider](docs/getting-started.md#choosing-an-inference-provider)**. - -When you are ready for the real thing: - -```bash -kars up --name prod-agent --region swedencentral --release -``` - -`--release` pulls the **public, cosign-signed images** from `ghcr.io/azure` into your ACR — **no local build, no Rust toolchain, no source checkout to compile.** (Drop `--release` to import from a source ACR, or pass `--build` to build from source — developer mode.) - -`kars up` provisions the AKS cluster, ACR, Foundry resource, Foundry-side Content Safety, controller, A2A gateway, Microsoft AGT AgentMesh relay+registry, and your first sandbox. Identity is gated by **one operator flag**: - -```bash -# Default — anonymous mesh tier, shared cluster Workload Identity for Foundry. -# Zero Entra prerequisites. Suitable for single-tenant clusters and demos. -kars up --name prod-agent --region swedencentral --release - -# Verified mesh tier — per-sandbox Microsoft Entra Agent ID. -# Each KarsSandbox (incl. spawned sub-agents) gets its own typed Entra -# agentIdentity SP + Foundry RBAC scoped to that SP + federated credential. -# Requires the Agent ID Developer directory role on the signed-in user. -kars up --name prod-agent --region swedencentral --release --mesh-trust=entra -``` - -`--mesh-trust=entra` activates the full **per-sandbox Microsoft Entra Agent ID** chain (Phase 5b/6.c): the controller provisions a typed `microsoft.graph.agentIdentity` SP per sandbox, assigns Foundry RBAC to that SP, wires a federated credential, and configures the AGT mesh relay+registry to verify peer JWTs against Entra's JWKS. The default `anonymous` skips Entra entirely and uses the cluster's federated Workload Identity for Foundry — same security model as v0.0.x. See **[`docs/agent-identity.md`](docs/agent-identity.md)** and **[`docs/architecture/entra-agent-id/`](docs/architecture/entra-agent-id/)** for the full chain. See **[`docs/getting-started.md`](docs/getting-started.md)** for the full walkthrough including how to bring your own AKS / Foundry / ACR. - ---- - -## What is built in - -### Twelve CRDs (ten workload + two infrastructure) - -`KarsSandbox` is the unit of work — one CRD per agent. The other nine **workload** CRDs bind policy, identity, peer relationships, memory, evaluation, and operations to it. Two **infrastructure** CRDs are written by the platform, not authored per agent. - -**Ten workload CRDs** (you author these): - -| CRD | Purpose | +| Resource | Purpose | |---|---| -| **`KarsSandbox`** | The agent itself: runtime kind, model, tools, mesh membership, governance profile. | -| **`A2AAgent`** | Public-ingress A2A 1.0.0 endpoint for peer-to-peer agent communication. | -| **`McpServer`** | An external MCP server the agent is allowed to call, with OAuth + allow-listed tools. | -| **`ToolPolicy`** | Per-tool gate (approval / rate-limit / commerce caps / AGT profile). | -| **`InferencePolicy`** | Per-tenant model routing, content-safety floor, and token budgets. | -| **`KarsMemory`** | Foundry Memory Store binding with project-MI auth (operator-provisioned today). | -| **`KarsEval`** | Reproducible evaluation runs against a sandbox spec. | -| **`TrustGraph`** | Cross-namespace / cross-cluster trust topology for the AgentMesh layer. *(`v1alpha1` — reconciler-only; router-side **mesh-admission gating** against the projected graph is on the [roadmap](docs/roadmap.md). KNOCK accept/deny stays agent-side — the router cannot decrypt the Signal session.)* | -| **`EgressApproval`** | Ephemeral, TTL-bounded extra egress hosts overlaid on the baseline allowlist. | -| **`KarsSREAction`** | Approval-gated, TTL-bounded write action proposed by the [autonomous SRE operator](docs/runbooks/sre.md). The controller executes it only when `spec.approval.state` is `Approved`, via a short-lived `TokenRequest` + scoped `ClusterRoleBinding` (least-privilege, auto-revoked). | - -**Two infrastructure CRDs** (platform-written, not per-agent): **`KarsAuthConfig`** (cluster-scoped singleton written by `kars mesh setup-trust` — the tenant-wide Entra Agent ID trust anchor) and the controller-internal **`KarsPairing`** record (binds sandboxes to AgentMesh registry IDs). - -That's **twelve CRDs in total** — ten you author, two the platform manages. Full schema in **[`docs/api/crd-reference.md`](docs/api/crd-reference.md)**. - -### Eight agent runtimes (plus BYO) - -You pick the runtime via `KarsSandbox.spec.runtime.kind`. The router, governance, isolation, and audit chain are identical across all of them. - -| Runtime | Language | Image dir | Status | -|---|---|---|---| -| **OpenClaw** (default) | TypeScript / Node | `sandbox-images/openclaw/` | ✅ | -| **Hermes** (Nous Research) | Python | `sandbox-images/hermes/` | ✅ | -| **OpenAI Agents SDK** | Python | `sandbox-images/openai-agents/` | ✅ | -| **Microsoft Agent Framework** | Python | `sandbox-images/maf-python/` | ✅ (`.NET` deferred) | -| **LangGraph** | Python | `sandbox-images/langgraph/` | ✅ | -| **LangGraph.js** | TypeScript | `sandbox-images/langgraph-ts/` | ✅ | -| **Anthropic Claude Agent SDK** | Python | `sandbox-images/anthropic/` | ✅ | -| **Pydantic-AI** | Python | `sandbox-images/pydantic-ai/` | ✅ | -| **BYO** | any | your image, our contract | ✅ | - -The BYO contract is documented in **[`docs/runtimes.md`](docs/runtimes.md)**. Semantic Kernel and MAF .NET are wired in the CRD enum but the adapter images are deferred — the controller emits a clear `ShapeInvalid` condition rather than silently mis-imaging the pod. - -### One mesh, one gateway, one CLI - -- **AgentMesh** — Signal Protocol (X3DH + Double Ratchet) inter-agent messaging with KNOCK trust handshake and per-message forward secrecy. No plaintext fallback. **The Signal session lives in the agent process**, not the router: **OpenClaw** bundles the AGT TypeScript SDK and **Hermes** the AGT Python mesh client, both wire-compatible (proven by `tests/e2e/interop/hermes_openclaw_bidi.sh`). The router holds **no** session keys and never does mesh crypto — it links the upstream `agentmesh` crate only for shared governance primitives and WebSocket-bridges opaque ciphertext to the relay. Every client is an upstream Microsoft AGT build — **no in-tree fork**.

Bridge depends on Kars; Kars +never depends on Bridge. -> ✅ **Every published artefact is signed.** All container images on `ghcr.io/azure` are **cosign keyless-signed** (verifiable in the Sigstore Rekor transparency log), carry an **SPDX SBOM**, and a **GitHub build-provenance (SLSA) attestation** — verify with `cosign verify` / `gh attestation verify`. The CLI is published to **npmjs as [`@kars-runtime/cli`](https://www.npmjs.com/package/@kars-runtime/cli)** with an SLSA build-provenance attestation (verify with `npm audit signatures`), and the CLI tarball on each GitHub Release is attested too. Install with no compile via the [Try it in five minutes](#try-it-in-five-minutes) quick-start. *(We're additionally working on publishing to crates.io / MCR — the GHCR + npm artefacts above are signed and usable today.)* +See [Kars and Kars Bridge](docs/concepts/kars-and-bridge.md). -**Status: active development; CRDs at `v1alpha1`.** The core data path (router, controller, A2A gateway, mesh) is feature-complete and exercised by CI (Kind E2E, chaos-tier fault injection, CNCF conformance self-assessment, plus a documented manual matrix on AKS — see [`tests/`](tests/)). The CRD surface is served at `v1alpha1` and may change between minor releases; the data path, security model, and audit chain are stable. See the **[latest release](https://github.com/Azure/kars/releases/latest)** and **[`CHANGELOG.md`](CHANGELOG.md)** for what shipped, and **[`docs/roadmap.md`](docs/roadmap.md)** for what's next. - -## Known limitations - -We would rather you find these in this list than in production.

Under the default, the relay accepts every peer at trust score `0`; KNOCK gating still happens but score-based admission is moot. Verified-tier registration (per-sandbox Entra Agent ID JWTs verified by the AGT relay against tenant JWKS) is fully wired in this repo; the AGT-side relay+registry patches are tracked upstream in [microsoft/agent-governance-toolkit#2659](https://github.com/microsoft/agent-governance-toolkit/pull/2659). One CLI flag (`--mesh-trust=entra`) is the whole opt-in; see **[`docs/security.md#trust-tiers-and-the-apiagentmesh-prerequisite`](docs/security.md#trust-tiers-and-the-apiagentmesh-prerequisite)** for the failure modes when the role / upstream patches are missing. -- **Mesh/spawn/handoff is fully wired for OpenClaw and Hermes; partial for the other adapters.** The encrypted AgentMesh (and the sub-agent spawn / handoff tools that ride on it) is exercised end-to-end for **OpenClaw** and **Hermes** (`tests/e2e/interop/hermes_openclaw_bidi.sh`).

A `KarsApproval` is a single human decision a `KarsTask` is waiting on: a +//! priced/external/irreversible action, a checkpoint sign-off, or a request to +//! raise a branch's autonomy tier.

When you +don't install it, you pay zero cost (no DaemonSet, no eBPF programs). + +## Why kernel-level + +Kars already enforces egress at two layers: + +1. **L4 `NetworkPolicy`** (port-level, `0.0.0.0/0 except RFC1918`), and +2. the **router's forward-proxy** CONNECT allowlist (host-level, from + `karssandbox--egress-allowlist`). + +Both are *in-band* — they are part of the thing being governed. A datapath +witness is *out-of-band*: it attaches eBPF programs in the kernel and records +every DNS query and outbound TCP connect a sandbox pod makes, independently of +the router. Comparing **observed** (kernel) against **declared** (controller) +yields a completeness proof: + +| Verdict | Meaning | +|---|---| +| `COMPLIANT` | **Strict** enforcement and every external host the kernel observed is in the declared allowlist. | +| `BEYOND-DECLARED` | **Strict** enforcement but the kernel observed egress to a host **not** in the declared allowlist. The router's proxy should have blocked the *connect*; a DNS-only observation means intent without a connect (still worth surfacing). A TCP connect to an undeclared host is a real finding. | +| `LEARN` / `UNCONSTRAINED` | The sandbox is in **learning mode** (`spec.networkPolicy.egressMode` != `Strict`, the default) **or** the declared allowlist is empty. Enforcement is not active, so reaching hosts beyond any baseline is expected — the witness records the observed set as the baseline you would promote into a `strict` allowlist rather than flagging it. | + +**DNS = intent, TCP connect = actual datapath.** The witness reports both.

Verify with: + ```bash + kubectl get nodes -o name | while read n; do echo "$n"; done + # on a node: ls /sys/kernel/btf/vmlinux (must exist) + ``` + AKS Azure-Linux and Ubuntu node images ship BTF. `kind` (kernel ≥ 5.8 with + BTF) works too — this witness was validated on `kind` (kernel 6.12, BTF present). +- The `kubectl gadget` client plugin (installed by `install.sh` if missing). +- Privilege: Inspektor Gadget runs a **privileged DaemonSet** in its own + `gadget` namespace (it must load eBPF programs and read `/sys`). This is the + one real cost of enabling the witness — review `deploy/ebpf-witness/` and your + cluster's PodSecurity posture before installing. + +## Install (gated, opt-in) + +```bash +# Explicit opt-in — refuses to run without it, so it never installs silently. +KARS_EBPF_WITNESS=1 deploy/ebpf-witness/install.sh + +# ...with a continuous (headless) witness that keeps recording in the background: +KARS_EBPF_WITNESS=1 deploy/ebpf-witness/install.sh --continuous +``` + +`install.sh`: +1. installs the `kubectl gadget` client if it isn't on `PATH`, +2. `kubectl gadget deploy` — the Inspektor Gadget DaemonSet + RBAC into the + `gadget` namespace, +3. with `--continuous`, creates two **headless** gadget instances + (`trace_dns`, `trace_tcp`) that run in the background and can be attached to + at any time (`kubectl gadget list` / `kubectl gadget attach `). + +## Produce a witness verdict + +```bash +# On-demand: capture a bounded window and cross-check every sandbox namespace. +deploy/ebpf-witness/witness-verify.sh # human table +deploy/ebpf-witness/witness-verify.sh --json # machine-readable +deploy/ebpf-witness/witness-verify.sh --window 30 # longer capture +deploy/ebpf-witness/witness-verify.sh --namespace kars-foo,kars-bar +``` + +The verifier is **self-contained**: it works whether or not you installed the +continuous instances — it runs a bounded `trace_dns` + `trace_tcp` capture, +reads each sandbox's `karssandbox--egress-allowlist` ConfigMap, and emits +a per-sandbox verdict.

On a plain Kars +cluster with no Bridge, `kubectl get cm kars-datapath-witness` is the whole API. + +The aggregator uses a dedicated least-privilege ServiceAccount +(`kars-witness-aggregator`): `apps/daemonsets:list` + `pods:list` + +`pods/portforward:create` (what `kubectl-gadget` needs to reach the gadget +pods), `configmaps:get,list` cluster-wide (declared allowlists), and +`configmaps:write` **only** on `kars-datapath-witness` in `kars-system`. + +## Consume the verdict + +- **Kars Bridge** — the Operator Console **Datapath witness** page reads the + ConfigMap via `GET /api/operator/datapath-witness` and renders per-sandbox + verdicts live. When the witness isn't installed it shows enable instructions, + never fabricated data. +- **Audit / receipts** — attach the verdict as a datapath-completeness claim + next to the signed run receipt. +- **Alerting** — a `BEYOND-DECLARED` with a real TCP connect to an undeclared + host is an egress-escape signal; forward to your SIEM. +- **Learn → strict promotion** — a `LEARN` verdict's `observed_dns` is exactly + the allowlist you would promote a learn-mode sandbox into. + +Because everything reads only core Kars objects (`KarsSandbox` + the +egress-allowlist ConfigMap the controller already publishes), the witness is a +standalone Kars artifact: it runs on any Kars cluster with **no Kars-Bridge +installed**. The `witness-verify.sh` on-demand verifier remains available for a +one-shot table/JSON without the continuous aggregator. + +## Uninstall + +```bash +deploy/ebpf-witness/uninstall.sh # removes the aggregator, headless instances + the IG DaemonSet +``` + +## Cost / safety notes + +- Zero cost when not installed. When installed: one privileged DaemonSet pod per + node + the eBPF programs the active gadgets attach (tracepoints/kprobes for DNS + and TCP connect — low overhead, per-event ring-buffer). +- The witness is **read-only**: it never blocks, drops, or modifies traffic. It + cannot be a datapath outage source.

The agent has **no network of its own** — every external call (model, tool, MCP, peer) goes through an in-pod Rust **inference router** that enforces identity, content safety, budgets, governance, and a tamper-evident audit chain.

If the task says \"hand to writer\", \"send to writer\", \"deliver to \", \"return to \", or describes a pipeline like \"analyst → viz → writer\", then route BOTH text/JSON (mesh_send) AND files (mesh_transfer_file) directly to that NAMED SIBLING with to_agent='' — do NOT send to 'parent'. Sending to 'parent' when the task specifies a sibling is a routing bug: parent will not forward to the sibling, and the sibling will time out waiting. Only fall back to to_agent='parent' when (a) the task explicitly says to return to parent / spawner, OR (b) you are the final agent in the pipeline (e.g. 'writer' producing the assembled brief), OR (c) the task names no downstream peer at all (typical for ordinary single-agent tasks — return final text/files to 'parent'). If the task targets DIFFERENT peers for different artifacts (e.g. \"send chart to viz and JSON to writer\"), resolve the target per artifact, not once for the whole batch. If unsure of the exact agent name, call `discover` once to list peers — but do not over-discover; one call per task is plenty.\n\nPeer name resolution: when your task content begins with a `Peer roster:` block, that roster is the single source of truth for sibling names. Use ONLY the names listed there with mesh_send / mesh_transfer_file — never invent variants, role descriptions, or your own name as a target. Resolve role references (\"the writer\", \"the analyst\", \"the graphic designer\") by matching them to the role text after each `—` in the roster. If the roster is missing OR a role reference does not unambiguously map to one entry, send a single mesh_send to 'parent' asking for the canonical name and wait for the reply — do NOT guess. Never use your own SANDBOX_NAME as `to_agent`; the gateway rejects self-sends.\n\nReceived artifacts persist on disk: files delivered to you via mesh_transfer_file are written by the gateway to /sandbox/.openclaw/workspace/incoming/ and STAY THERE across the rest of your task — they are not consumed by reading the inbox. If you previously saw a file_transfer in mesh_inbox (with a `saved_to` path) and later need to confirm what you have, list /sandbox/.openclaw/workspace/incoming/ via exec_command (`ls -la /sandbox/.openclaw/workspace/incoming/`) rather than re-polling the inbox. Avoid reporting \"no artifacts received\" if the directory contains the expected files; treat the filesystem as the source of truth for delivered artifacts.\n\nFinal deliverables: when you have produced a final artifact (markdown, document, image, dataset, JSON, etc.), the last step before returning your textual summary should be mesh_transfer_file(to_agent='', file_path='/sandbox/.openclaw/workspace/', description='') where follows the routing rule above. Files left only in your local /sandbox are not visible to other agents and will be lost when the sub-agent exits. If you produced multiple outputs (brief.md + chart.png + hero.png), call mesh_transfer_file once per file, resolving the target per artifact. Trust mesh_transfer_file's return value (`status: 'delivered'` plus a `message_id`) as proof of delivery — there is no separate inbox ack to wait for, so do not block on one.
