See [docs/pod-agents.md](docs/pod-agents.md). | +| `internal/authz` | The authorization pre-flight: one owner, plain control flow, credentials written to a Secret so a value never enters workflow state. | +| `internal/identitylink` | Client for agent-controller's integration-gateway credential API. | +| `internal/callertools` | Consumer-supplied tools over the OpenAI facade (upstream ADR 0035). | +| `internal/temporal/activities` | All non-deterministic work (LLM calls; later: Qdrant, ToolRun CRs, identity). | +| `internal/llm` | Minimal OpenAI-compatible chat client (base URL overridable). | +| `charts/durable-agents` | Helm chart: gateway + worker.

The gateway does **update-with-start** on `conversation-`: + starts the workflow if absent, then sends the turn as a `user-turn` + Update. +3. The workflow runs the ported agent loop, every LLM/RAG/k8s call an + activity: active-skill fit check (skips retrieval on a hit) → capability + gate (conversational turns answer directly) → RBAC-filtered skill + retrieval from Qdrant → skill selection → resolve the skill's declared + tools → plan ⇄ runTool loop (max 4 steps; tool ids re-validated; ToolRun + CR + durable signal wait per call) → compose the reply around the + verbatim tool result. +4. The workflow idles under a 30-minute timer (then completes) and + continues-as-new after 40 turns to bound event history. + +No session store, no Redis, no in-memory pending state — the workflow *is* +the session, including the active skill and continuation tokens. + +## Caller-supplied tools + +Any OpenAI-compatible client can offer its own functions in the request body +and have them selected alongside the in-cluster catalog (upstream ADR 0035). +The client executes them; this system only decides one fits, returns +`finish_reason: "tool_calls"`, and picks the conversation back up when the +client resends with `role: "tool"` results. + +Costs nothing when unused: definitions are keyed by content hash, so identical +tools embed once ever, and a caller sending at most `AGENT_CALLER_TOOL_TOP_K` +(default 5) tools never touches the store at all. Their own `caller_tools` +collection, never the catalog's — one caller's ephemeral definitions must not +enter another's candidate set. A skill can refuse them with +`allowCallerTools: false`. + +## Event-driven turns (`/invoke`) + +An adapter (agent-controller's integration-gateway) posts +`{request, sessionId, event}` and polls: + +```bash +curl -s -XPOST localhost:8080/invoke -H 'Content-Type: application/json' -d '{ + "request": "an issue was labeled", + "sessionId": "github:acme/widgets#7", + "event": {"source":"github","event":"issues","action":"labeled", + "labelName":"ai-triage","owner":"acme","repo":"widgets", + "issueNumber":7,"title":"Crash on save"} +}' +# {"id":"conversation-github-acme-widgets-7.","status":"pending"} + +curl -s localhost:8080/invoke/ +# {"id":"...","status":"succeeded","result":"..."} +``` + +When the `event` matches an `IntegrationRoute` CR, its `promptTemplate` is +rendered and the named Skill/Agent is dispatched directly — no RAG retrieval +(upstream ADR 0024). No match behaves exactly as before the field existed. + +The invocation id names a workflow update, so a poll is answered from +Temporal rather than from process memory: any replica can serve it, and a +gateway that dies mid-turn costs the caller nothing. This is upstream's +ADR 0006 restart/scale-out gap, and the "durable invocation records, which +this does not attempt" that ADR 0033 closes on. + +`event.senderLogin` says which human triggered the turn, and therefore which +stored credentials the run may receive.

The workflow awaits the signal under a durable timer — fixing + the missing `awaitJob` timeout. +5. **Heavyweight pod agents (opencode-swe-agent) become checkpoint-resume + Jobs.** Each work step is a one-shot Job carrying the continuation token + (repo/branch/PR/session).

Its thesis — that most of upstream's coordination +machinery compensates for a loop that is not durable — held up: seven +milestones landed, and the four ad-hoc state stores ADR 0001 named were +replaced by workflow state. + +The maintainer has agreed to take it upstream. That changes the constraints in +two ways. + +First, upstream did not stand still. In the ~six weeks after the fork it moved +237 commits and added twelve ADRs (0024–0035), including a deterministic event +router, an authorization pre-flight with principals, caller-supplied tools, a +durable credential store, and — most consequentially here — a production +Claude-based coding agent built on the very NATS channel ADR 0001 dropped. + +Second, "a fork that proves a point" and "a change a maintainer can merge" are +different artifacts. The second one has to not regress anything. + +The catch-up work is tracked in +[upstream-catchup-plan.md](../upstream-catchup-plan.md). + +## Decision + +### D1. Catch up on the loop and the contracts, not the whole system + +Port upstream's agent-loop semantics and CRD schema, plus the wire contracts +needed to sit behind the real integration-gateway: the `/invoke` event +descriptor, the signed sender assertion, and the identity-link gateway client. + +Do **not** reimplement services that stay upstream — the webhook adapter, the +credential store, the coding-agent images. Anything reimplemented is code that +gets deleted during the merge, and a second implementation of credential +keying is the shape of a real upstream bug (PR #144). + +### D2. Pod agents keep their NATS channel; ADR 0001 §6 is amended + +ADR 0001 §6 said NATS is dropped and the bidirectional agent channel becomes +workflow signals. That reasoning still holds for agents we write. It does not +hold for the ones already running. + +Since the fork, upstream built the live opencode tunnel (ADR 0026), sub-agent +tool calls (ADR 0028) and the reply-ack hold (ADR 0033) on that channel, and +`claude-code-swe-agent` — which speaks it — became the **production triage +agent**. Requiring it to be rewritten as a precondition for merging would trade +the maintainer's working system for our architectural preference. + +So there are three execution styles, all speaking the same parent-facing +signal protocol: + +| Style | What it is | +| ----- | ---------- | +| `AgentWorkflow` | the declarative loop; a sub-agent is a child workflow | +| `PodAgentWorkflow` | checkpoint-resume step Jobs (ADR 0001 §5) | +| `BridgedAgentWorkflow` | an **unmodified** upstream `AgentRun` over NATS | + +The bridge is where ADR 0001's thesis gets its sharpest demonstration rather +than its widest application. ADR 0033 exists because an agent turn's work lives +in a Job pod while the turn's *wait* lives in an orchestrator pod, and the +second lifetime is far shorter — eleven rollouts in fourteen hours, in the +incident that prompted it. Core NATS has no durability, so a `reply` published +while nothing is subscribed is discarded, and the fix was to make the agent +hold its concluding message, re-offering every 10s until acked. + +Here the wait is a workflow, so the buffer has nothing to buffer against and +the bridge acks on receipt — which ADR 0033 itself names as its exit condition +("`AGENT_REPLY_ACK_TIMEOUT_MS=0` is the switch that retires it"). The hold is +not deleted, because the bridge process is *not* the workflow: the ack is sent +only after Temporal accepts the signal, so a bridge crash leaves the agent +still holding, which is the recoverable state. + +### D3. Upstream shape: TypeScript front door, Go loop, feature-flagged + +`agent-orchestrator` keeps `/v1/chat/completions`, `/invoke`, identity and RBAC +resolution, the credential store wiring, and both launchers. +`AGENT_ENGINE=langgraph|temporal` selects whether a turn runs +`buildAgentGraph()` or does update-with-start against the Go worker. + +That HTTP and identity layer is where essentially all 237 commits of churn +happened. Replacing the *loop* is the claim ADR 0001 makes; replacing the +*front door* is unrelated risk bundled into the same review. + +One consequence, decided deliberately: **the authorization pre-flight stays in +TypeScript upstream.** `internal/authz` exists and is fully tested, because a +standalone deployment needs it — but upstream the orchestrator runs the +pre-flight and passes the verdict in. Two owners of credential keying is +exactly what ADR 0030 §1 consolidated away. + +### D4. Import by `git subtree`, and stay local until told otherwise + +The engine lands as a new top-level directory in agent-controller with history +preserved, so ADR 0001 and the milestone commits survive as the design record +the maintainer reviews. Nothing is pushed and no PR is opened without explicit +authorization each time. + +## Consequences + +- **Nothing upstream regresses on merge day.** Default `AGENT_ENGINE=langgraph` + means the switch is inert until flipped, and the existing e2e suite is the + acceptance test rather than a new one written to fit. +- **Two agent loops exist for a while.** That is the cost of a reversible + merge. The LangGraph graph is deletable once the flag has been flipped long + enough to trust. +- **Temporal is already deployed** on the target platform (confirmed with the + maintainer, 2026-08-02).

The first +step of an episode gets the user's goal; later steps get the user's answer +to your question. + +Output: emit the usual `accepted → progress* → succeeded|failed` stream. +The `succeeded` event's `result` is the envelope: + +```json +{ + "status": "question" | "final", + "message": "the question for the user, or the final answer", + "continuation": "opaque resume token (repo/branch/PR/session…)" +} +``` + +Then **exit 0**. `status: "question"` means: the workflow relays `message` +to the user, waits (hours are fine — no pod exists), and launches the next +step with the answer + your `continuation`. `status: "final"` ends the +episode; the token is banked per-agent in the conversation and prepended to +this agent's next episode. + +A plain string `result` is treated as `{"status": "final"}` — any ordinary +tool can serve as a degenerate one-shot agent. + +## Identity gate + +If the Agent CR declares `identityProviders`, the authorization pre-flight +runs in the **parent conversation** before any child starts (upstream ADR +0030 — one owner, plain control flow, no model call involved).

In Temporal, an activity result that lands in workflow state is +written to **event history** — durably, in the clear, forever. That is strictly +worse than the TS property, not equal to it. So the authorize activity returns +the **name of the per-run Secret** and never a value; the launcher redeems it. +Add the Go analogue of §3's test: assert no credential material appears in any +workflow input, result, or activity payload on a turn that resolves every +provider. + +**Build this behind an interface with two implementations** — `GatewayAuthorizer` +(standalone/dev) and `PreAuthorized` (trusts a verdict passed in on +`TurnInput`). Per D3, upstream will use the second: authorization stays in +TypeScript, keeping ADR 0030's "one authorization owner" property intact rather +than creating the second copy that ADR named as the shape of the #144 bug. + +### A5. Caller-supplied tools · ADR 0035 + +- `internal/callertools`: parse `tools` / `tool_choice`; hard caps on count and + on description/schema size, rejected with an OpenAI-shaped `400`; sha256 + content-hash point ids; `caller:` namespacing so a caller tool can + never shadow a `Tool` CR. +- New Qdrant collection `caller_tools` (same embedder/vector size), `lastSeenAt` + + `prune()`. **Skip the store entirely when the caller sent ≤ K** (default 5). + Search is restricted to ids taken from *this request's* body, which is what + makes cross-caller leakage structurally impossible and why this collection + alone carries no RBAC filter. +- Parse `assistant.tool_calls` + matching `role:"tool"` messages out of the + incoming `messages` array into seeded `[]ActionRecord`. This is the resume + path, and seeding bounds the resumed loop for free via `maxToolSteps`. +- **Second terminal shape**: `TurnResult` += `PendingToolCalls`. Render it in + the blocking facade, the streaming facade, and `/invoke`'s polled record. +- Untrusted-block rendering in the planner prompt (one trust level below a Tool + CR description, two below Skill markdown). +- `isInternalUiTaskRequest` short-circuit — Open WebUI's title/tag/query + completions must return prose and can never emit `tool_calls`. In our shape + that means short-circuiting **before** update-with-start, so the housekeeping + request never starts or touches a conversation workflow. +- `Skill.allowCallerTools` gate. +- Port the seeded-result finish guard (`139039f`): the verbatim-repeat branch in + `planAction` must carry `lastHistoryResult(state)` like its siblings. + +### A6. Sub-agent tool calls · ADR 0028 + +Cheaper here than upstream, and worth saying so in the PR. Upstream needs a +`tool_call`/`tool_result` NATS pair, a `callId`-keyed pending map, and an SDK +method. A child workflow just calls the existing `runTool` helper directly. + +- Gate on `agent.ToolRefs`, resolved by a **non-RBAC id lookup**. ADR 0028's + reasoning carries over exactly: this asks which tools the *operator* declared + this agent may call, not which tools the walk-in caller may reach. +- Same v1 scope cut: agent-backed tools are not reachable from a sub-agent's own + `toolRefs`. +- The one place the NATS pair is still needed is A9 (a pod agent calling a tool + from inside its own image). + +### A7. Loop-semantics fixes + +- **Fallback path (pre-existing gap).** Port `selectFallbackTool` + + `noMatchFallback` + `bestEffortResponder` + `appendSelfImprovementSuggestion`. + Today a no-skill turn drops straight to `bareAnswer`, so the full-catalog tool + search never happens. +- **`toolFitChecker` activity** (pre-existing gap) — needed by both the fallback + path and the next item. +- **`hasOutOfScopeToolMatch`** (`8e05c6b`): the active-skill fit check only + judges topic continuity, so "use your kubectl access to debug this" mid-task + inside `skill-web-search` passes the fit check and gets absorbed. Query the + top-K catalog under the caller's roles, filter to candidates outside the + skill's `toolIds`, and force full retrieval on a hit. +- ~~**Container-tool identity gate** (ADR 0032 §5)~~ — **moved to A4.** The gate + itself is small, but it needs a resolved token turned into a Secret + reference, which is precisely the credential plumbing A4 builds (and which + A4 shapes deliberately so a value never enters workflow state). Today's + `GetIdentityLink` activity returns no tokens at all and says so in its own + comment. Doing a half-version here would be work A4 deletes. + +### A8. Docs + +- New `docs/adr/0002-upstream-integration.md` recording D1–D4. +- ADR 0001: mark milestone 8, and correct §6 — NATS is no longer dropped + wholesale (D2). +- `docs/pod-agents.md`: gap #1 is **closed upstream**; gap #2 is replaced by the + NATS bridge. +- README component table. + +### A9. NATS pod-agent bridge · the D2 workstream + +Largest new surface, and what lets `claude-code-swe-agent` run unchanged. + +- `internal/agentrun`: create an `AgentRun` CR; a worker-side subscriber + translates `ready/progress/reply/failed` and `tool_call` up-messages into + workflow signals, and workflow commands into `prompt/cancel/signal`, + `tool_result` and `reply_ack` down-messages. +- Sub-agent `tool_call` → the A6 dispatch helper → `tool_result`. +- **`reply_ack` is acked on receipt.** ADR 0033's hold exists because the + orchestrator holding the wait can die and core NATS has no durability. A + Temporal workflow's wait *is* durable, so the buffer has nothing to buffer + against: set `AGENT_REPLY_ACK_TIMEOUT_MS` low and ack immediately. ADR 0033's + own last line calls this out — "`AGENT_REPLY_ACK_TIMEOUT_MS=0` is the switch + that retires it." + + Caveat to verify, not assume: the *bridge process* is not the workflow. A + crash between "NATS delivered the reply" and "signal accepted by Temporal" + still loses it. Ack **after** the signal is accepted, and treat duplicate + `seq` re-offers as idempotent — ADR 0033 already guarantees a re-offer reuses + its original `seq` precisely so a consumer can tell. + +--- + +## Phase B — land the engine in agent-controller + +### B1. Import +`git subtree add --prefix engines/temporal ` — history and +ADR 0001 preserved. Self-contained Go module. Add two images (worker, gateway) +to `skaffold.yaml` and `release.yml`'s matrix, and `go build/test/vet` to +`ci.yml`. + +### B2. The switch +`AGENT_ENGINE=langgraph|temporal` in agent-orchestrator's config, defaulting to +`langgraph`. The two call sites in `server.ts` branch between +`buildAgentGraph().invoke(...)` and a `TemporalEngineClient.runTurn(...)` doing +update-with-start. + +Everything outside the graph is shared and untouched: identity resolution, +sender assertion, the Kubernetes-Secret credential store, both launchers, +session pages, the OpenAI facade, `isInternalUiTaskRequest`. + +Per D3 and A4, the orchestrator runs the authorization pre-flight **before** +starting the turn and passes the verdict — a Secret *name*, never a value — +into the workflow. One authorization owner, and no credentials in Temporal +event history. + +### B3. Chart +New `charts/agent-controller/charts/temporal-engine` subchart (worker + gateway), +`condition: temporal-engine.enabled`, default off. It takes a Temporal +**address** — the platform already runs a cluster, so no server is bundled and +no new stateful component appears. Add it to `values-ci-all.yaml` so +`validate-crds` renders it. + +### B4. CRDs and RBAC +No new CRDs — `ToolRunSpec.secretEnv` and `Tool.identityProviders` already +exist. Confirm the worker's ServiceAccount matches the orchestrator's existing +grants: `toolruns` create/get, `agentruns` create/get, `tools`/`skills`/`agents`/ +`integrationroutes` get/list/watch, `secrets` create/patch. + +### B5. Parity gate +The existing `e2e/specs` suite is the acceptance test — run it whole under +`AGENT_ENGINE=temporal`. Two expectations, stated separately because they are +judged differently: + +- Everything else must pass **unchanged**. A failure is a real parity gap. +- `resilience` / `rollout-recovery` should **change behaviour for the better**. + ADR 0033's "the interrupted turn itself is still lost" should stop holding, so + those specs need re-baselining rather than passing as written. That + re-baselining *is* the evidence for the PR. + +### B6. ADR +`docs/adr/0036-temporal-execution-engine.md`, adapted from ADR 0001 plus D1–D4, +explicitly naming what it retires or amends: 0002 (LangGraph), 0006 (in-memory +invocation map), 0012/0017 (session store), 0033 (reply-ack hold), and partially +0034 (session pages in an ephemeral Redis). + +### B7. PR sequence +Not one PR: + +1. subtree import + CI/build wiring — no behaviour change +2. `AGENT_ENGINE` switch + engine client, default `langgraph` — no behaviour change +3. chart subchart, default off +4. e2e under the flag + ADR 0036 +5. flip the default — the maintainer's call, on their evidence + +--- + +## Open questions for the maintainer + +1. ~~**Temporal as a dependency.**~~ **Answered 2026-08-02: the platform already + runs Temporal.** The subchart takes an address; no server is bundled and no + new stateful component is introduced. This was the strongest argument against + the change and it does not apply. +2. **Does the reply-ack hold get retired, or kept as belt-and-braces?** A9 argues + it can be acked on receipt under Temporal. Keeping it costs nothing but keeps + a mechanism alive that no longer has a failure to prevent. +3. **Session pages** (ADR 0034's unfixed follow-up: links posted into GitHub + comments, opened days later, backed by an ephemeral Redis). Workflow state + could hold these. In scope, or a separate fix? +4. **Checkpoint-resume's future.** With D2 keeping the NATS path, is the + step-tool contract worth keeping as a second way to write an agent, or does + it get dropped to reduce surface area? diff --git a/engines/temporal/go.mod b/engines/temporal/go.mod new file mode 100644 index 0000000..b4944a9 --- /dev/null +++ b/engines/temporal/go.mod @@ -0,0 +1,93 @@ +module

Install its charts per its README (`agent-controller` chart + first, then `community-components` for the sample catalog). Default + namespace assumption here: `controller-agent`. +2. **Temporal** — e.g. the `temporalio/temporal` Helm chart (the + `temporal-local` repo's helmfile does this).
