The Gateway substrate (`bgagent-linear-gw-*`, the M2M inbound, `gateway_auth.py`) is **not** wired for Linear; it stays available for the general MCP control plane. + +**Rejected (corrections to earlier drafts):** +- **No Linear MCP at all** (supersedes the earlier "optional Linear MCP via `actor=user` Gateway grant" — that path is live-proven non-functional on one app). +- **No two Linear OAuth apps.** One app, `@bgagent`, deterministic. +- **No claim that two `actor=app` authorization-code prompts can coexist** — Linear's docs are explicit that non-`client_credentials` app tokens cannot exist in parallel; moot now that Linear has no MCP leg needing a second grant. +- The **general MCP Gateway control plane (§4) stands** — this decision is Linear-specific, not a retreat from Gateway-fronted MCP for other registered servers. + +## Identity propagation for per-user MCP is UNRESOLVED + +Per-user `McpCredential` selection requires the Gateway to know *which task-user* is invoking — and that is not yet solved: + +- **Today the Gateway inbound auth uses an M2M JWT** (a Cognito client-credentials token the agent mints). An M2M token identifies the *workload*, not a user. +- **An M2M inbound JWT cannot select a per-user vaulted MCP credential** — there is no task-user subject in it for the vault to key on. So per-user MCP is not achievable on the current inbound path. +- **Before claiming per-user MCP support, this ADR requires a specified, trusted task-user identity propagation** from the triggering event → the agent → the Gateway inbound (e.g. a user-scoped JWT or a verified user-id claim the Gateway authorizer trusts). Until that is designed and validated, `McpCredential` is workspace-scoped at best, and per-user MCP tool attribution is out of reach. This is an explicit open item, not an assumed capability. + ## Consequences - (+) **One credential abstraction, not N resolvers.** New integrations register an adapter against one contract instead of re-implementing fetch + refresh + race handling per provider. -- (+) **Per-user, per-repo scoping replaces the shared PAT.** Tokens bind to `(workload_identity, user_id)`, so the single GitHub PAT covering every repo and user gives way to scoped, short-lived credentials. -- (+) **Cryptographic attribution, not asserted attribution.** OBO delegation carries an `act` claim (RFC 8693 delegation mode, `user ← agent`), which is joinable to #245's `trace_id` and #237's `correlation` block. The *who acted* is verifiable, not inferred from a webhook payload. +- (+) **Execution semantics and credential transport are separate axes.** Deterministic ops are always direct-GraphQL-from-Lambda; MCP is always Gateway. There is no per-vendor "transport mode" to special-case — the split is fixed by an operation's reliability requirement, not by the vendor. (Supersedes the rejected two-flag `lifecycleViaGateway`/`gatewayOAuthOk` derivation.) +- (+) **Three explicit credential types, not one token.** `ChannelCredential` (workspace-scoped, deterministic APIs), `McpCredential` (user-scoped, Gateway tools), `McpRegistration` (endpoint + tool/workflow bindings) keep the deterministic and MCP planes independently reasoned and independently failed-closed. +- (+) **Workspace-scoped `ChannelCredential` replaces the shared PAT / per-workspace SM secret with a vault-managed credential.** Deterministic APIs bind to `linear-workspace:` (not per-user), and the vault owns refresh — retiring the SM refresh/write-back. Per-**user** scoping applies to `McpCredential` only, and is gated on identity propagation (below), not assumed. +- (+) **Cryptographic attribution is available on the MCP/OBO path where per-user identity reaches the Gateway.** OBO delegation carries an `act` claim (`user ← agent`) joinable to #245's `trace_id` / #237's `correlation`. NOTE: on the deterministic `ChannelCredential` path the acting identity is the workspace app-actor, so per-user *credential* attribution there is via #245 logs, not the token; cryptographic per-user attribution requires the unresolved task-user propagation (P5). - (+) **Operators can bring their own IdP.** The inbound descriptor lets a deployment run on Okta, Entra, or Keycloak without forking handler code. - (+) **Backend-agnostic.** The same seam serves the AgentCore Runtime and ECS backends, matching the design posture already documented for the SessionRole in [SECURITY.md](../design/SECURITY.md). - (−) **A new abstraction plus an adapter registry to maintain.** Two seams and their adapter sets are added platform surface; mitigated by keeping the inbound descriptor a parameterization of a single verification path (see the risk below) and the outbound contract a thin selector over the existing flows. - (−) **AgentCore Identity adds a managed dependency and token-vault cost.** Vault fetches (`GetResourceOauth2Token` / `GetResourceApiKey`) bill at `$0.010/1,000`. The ECS in-process resolver path remains available where that dependency is unwanted. +- (!) **Per-user MCP is not yet achievable — task-user identity propagation is unresolved.** The Gateway inbound is an M2M JWT that identifies the workload, not the user, so it cannot select a per-user `McpCredential`. This must be designed + validated (P5) before per-user MCP is claimed; until then MCP credentials are workspace-scoped at best. +- (−) **Linear loses MCP tool-use — replaced by deterministic paths.** The 9 `mcp__linear-server__*` tools retire: writes were already deterministic in Lambda; reads become pre-hydrated context (#176 `context-hydration.ts`) + authenticated attachment fetch (#176 `resolve-url-attachments.ts` + `@bgagent` bearer). Cost: the agent can no longer make *arbitrary* live Linear queries mid-task — it works from pre-hydrated context. Accepted: live-proven that Linear MCP via Gateway doesn't work on one app, and a second app is rejected. The general MCP Gateway control plane (§4) is unaffected — this is Linear-specific. - (!) **The inbound seam must not become a second auth code path.** A descriptor that grew its own verification logic would drift from the shipped Cognito/HMAC path and create two implementations to keep in sync. That is the exact cedar-parity drift hazard ADR-014 calls out. Mitigation: exactly **one** inbound verification implementation; the descriptor only parameterizes it (discovery URL, audience, client list, claim gates), never reimplements it. ## Phasing @@ -72,9 +146,15 @@ The abstraction is intentionally a contract, not a forklift of credential handli | Phase | Action | Gate | |---|---|---| | P0 ✅ | Re-validate `USER_FEDERATION` / OBO post-GA against the live service. | **Done 2026-06-14 (`us-east-1`): GO-LIKELY** — parked PAR bug does not reproduce (see [#249](https://github.com/aws-samples/sample-autonomous-cloud-coding-agents/issues/249)).

You can use them independently 2. **REST API** (direct) - Call the Task API endpoints directly with a JWT token. Best for building custom integrations, dashboards, or internal tools on top of the platform. Full validation, audit logging, and idempotency support. 3. **Webhook** - External systems (CI pipelines, GitHub Actions) can create tasks via HMAC-authenticated HTTP requests. Best for automated workflows where tasks should be triggered by events (e.g., a new issue is labeled, a PR needs review). No Cognito credentials needed; uses a shared secret per integration. 4. **Slack** - Submit tasks by @mentioning the bot and receive threaded progress notifications with reaction-based status. See the [Slack setup guide](./SLACK_SETUP_GUIDE.md). -5. **Linear** - Apply a label to a Linear issue to trigger a task; the agent posts progress comments back on the issue via Linear's MCP server. See the [Linear setup guide](./LINEAR_SETUP_GUIDE.md). +5. **Linear** - Apply a label to a Linear issue to trigger a task; the platform posts progress comments and status reactions back on the issue as it works. The label has one variant — `bgagent` (do it) and `bgagent:help` (explain the labels). See [Trigger labels](./LINEAR_SETUP_GUIDE.md#trigger-labels) in the Linear setup guide. 6. **Jira** - Add a label to a Jira Cloud issue to trigger a task; a dedicated Forge `bgagent` app posts comments and transitions through Jira REST v3 while the triggering human remains the task owner. See the [Jira setup guide](./JIRA_SETUP_GUIDE.md). For example, a team might use the **CLI** for ad-hoc tasks, **webhooks** to auto-trigger `coding/pr-review-v1` on every new PR via GitHub Actions, **Slack** for quick team-wide requests, **Linear** or **Jira** for tickets that already live in the PM tool, and the **REST API** to build a dashboard that tracks task status across repositories. diff --git a/docs/research/a4-stacked-base-branch-design.md b/docs/research/a4-stacked-base-branch-design.md new file mode 100644 index 000000000..4df26cd7f --- /dev/null +++ b/docs/research/a4-stacked-base-branch-design.md @@ -0,0 +1,75 @@ +# Base-branch targeting design for orchestrated children + +Decided: **stacking, no delay, full code visibility**, and **multi-dep +(diamond) is first-class** (not deferred). + +## The uniform rule + +Every child branches so it *sees all its predecessors' code* without +waiting for a human merge: + +| Child shape | Base branch | Mechanism | PR diff | +|---|---|---|---| +| **0 predecessors** (root) | `main` | branch off main (today) | clean | +| **1 predecessor** (linear) | predecessor's branch | true stack (`base = pred branch`) | clean (only child's changes) | +| **N predecessors** (diamond) | `main` + merge all predecessor branches in | branch off main, octopus-merge predecessors | noisier (shows merged-in code until predecessors land) | + +Single-predecessor is the clean stacked-PR case.

Spawn the re-stack as a normal agent task whose job is to resolve the +conflict and push — **PR review is the safety net** (a human reviews the +re-stacked PR like any other). This matches the existing +`_merge_predecessor_branch` philosophy (abort the raw merge, hand the agent +a clean tree + a note) and avoids turning every predecessor edit into a +human interrupt. Rationale: the agent already resolves merge conflicts as +part of normal work; a stale-dependent is a coding task, not a policy +decision. + +### Cascade + bounding + +- A re-stack of D pushes new commits to D → if D itself has dependents, they + are now stale → cascade.

The +dependency is physical (git branch lineage), so a downstream change sees +upstream code the moment the branch exists — **no waiting for merge.** + +When an upstream PR changes after review, the stack must be **restacked** +(rebased): "later diffs cannot be landed to the main branch while they +don't contain changes from the updated Diff 1" → resolved via +`git rebase -i` up the stack (Pragmatic Engineer). Tools (ghstack, +Graphite) automate this restack. + +## Q4 — Tooling: ghstack (Meta's open-source tool) + +ghstack (https://github.com/ezyang/ghstack) — "Conveniently submit stacks +of diffs to GitHub as separate pull requests." +- Each commit on top of `main` becomes its own PR. +- Land with `ghstack land $PR_URL` — lands a ghstack'd PR (handles the + base rewriting so the rest of the stack stays correct). +- Stack another PR by `git commit` on top + re-run `ghstack`. +This is the closest reference for an **automated agent** opening stacked +PRs: one branch/PR per commit, tool owns the base-branch bookkeeping. + +## Q5 — Auto-merging a stack (GitHub merge queue) + +GitHub **merge queue** supports ordered, stack-like merging +(https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-a-merge-queue): + +- Entry gate: "Once a pull request has passed all required branch + protection checks, a user with write access ... can add the pull + request to the queue." → **required status checks + approvals** gate it. +- Ordering: "merged in a first-in-first-out order where the required + checks are always satisfied." +- Stacking semantics: each queued PR's temp branch "contains code changes + from the target branch, pull request #1, and pull request #2" — i.e. + later entries build on earlier ones, exactly like a stack. +- Caveat: cannot be used with wildcard (`*`) branch protection patterns. + +So "auto-merge the stack once all green + approved" is a real pattern, but +it rides on branch-protection + merge-queue config — a per-repo/per-project +policy decision, hence a follow-up for ABCA rather than MVP. + +## On research papers + +Stacked diffs is an **industry practice**, not an academic topic — there +is no peer-reviewed literature on "stacked PRs" mechanics.

The only differences are `cpu`/`memoryLimitMiB` and the build-tier-only `BUILD_VERIFY_TIMEOUT_S`. Routing is a fallback-safe boolean: an older deploy without the planning def wired simply runs read-only workflows on the build def (never worse than before).

Problem + +An ECS-configured repo (`compute_type: ecs`) runs **every** task on the one Fargate task +definition in `EcsAgentCluster` — the BUILD tier. Its size is measured, not guessed: a fully +parallel `mise run build` of this repo (agent:quality ‖ cdk:build ‖ cli:build ‖ docs:build, each +fanning out worker fleets) peaks ~31.6 GB and OOM-killed a 32 GB task. The build tier serialises +with `MISE_JOBS=1`, which brings the measured peak down to ~3.1 GB, so the shipped default is +4 vCPU / 16 GB — roughly 5x headroom over what it actually uses. + +But a read-only workflow such as **`coding/pr-review-v1`** clones and reads/greps to reach a +conclusion. **It never builds.** Running it on the build box is a large over-allocation for a +clone-and-read workload (and, on a stack that hasn't provisioned ECS at all, it just fails at +session-start). + +The current code has an explicit decision against the naive fix (`orchestrator.ts:242–252`): *"do +NOT special-case read-only workflows to agentcore … a repo big enough to need the ECS build tier for +building is also big enough to OOM the fixed AgentCore microVM just reading it."* That reasoning is +about **not routing a read-only task to the wrong substrate FAMILY** (ECS repo → AgentCore). It +does **not** say reading needs the *same size* as building. This proposal threads that needle: **same family +(ECS repo → ECS planning, so the OOM concern is respected), right-sized (a smaller task def, since +planning doesn't build).** + +## 2. Proposal + +Add a **second, smaller Fargate task definition** to `EcsAgentCluster` for **read-only** workflows, +and route by `workflowIsReadOnly` in the ECS compute strategy. Keep the 64 GB def for build +workflows. + +### 2a. Construct — `ecs-agent-cluster.ts` +- Add a `planningTaskDefinition` (a second `FargateTaskDefinition`) alongside the existing + `taskDefinition`. Suggested size: **8 GB / 2 vCPU** (valid ARM64 Fargate combo). Rationale: a + clone + read + a bounded set of file reads into the model context; no parallel build storm. If + 8 GB proves tight for a very large clone, 16 GB / 4 vCPU is the next step — but start small and + size up on evidence (mirror the existing sizing-history discipline in the file). + - It reuses the SAME container image, log group, task role, execution role, session role, + payload-bucket + artifacts-bucket grants, and env as the build def — the ONLY difference is + `cpu`/`memoryLimitMiB`. Factor the container definition into a small helper so both task defs + share it (avoid drift in grants/env — the ECS-parity bugs in the history all came from one + task role/env missing something the other had). + - Do NOT set `BUILD_VERIFY_TIMEOUT_S: '3600'` on the planning def (that's a build-tier concern; + a read-only planner never runs the post-agent build verify). +- Expose `planningTaskDefinition.taskDefinitionArn` from the construct (new public field, mirror + `taskDefinition`). + +### 2b. Stack wiring — `agent.ts` + `task-orchestrator.ts` +- Pass the new ARN into the orchestrator's `ecsConfig` as `planningTaskDefinitionArn` + (alongside the existing `taskDefinitionArn` at `agent.ts:704`). +- Orchestrator construct (`task-orchestrator.ts:271`) injects a new env var + `ECS_PLANNING_TASK_DEFINITION_ARN` next to `ECS_TASK_DEFINITION_ARN`. + +### 2c. Routing — `strategies/ecs-strategy.ts` +- `startSession` already receives `blueprintConfig`; thread the **workflow id** (or a + pre-computed `readOnly` boolean) into the strategy input. `orchestrate-task.ts` already computes + `workflowIsReadOnly(workflowId)` for preflight (line 121) — pass that same boolean down. +- In `RunTaskCommand` (`ecs-strategy.ts:206–208`), select the task def: + `taskDefinition: readOnly ? ECS_PLANNING_TASK_DEFINITION_ARN ?? ECS_TASK_DEFINITION_ARN : ECS_TASK_DEFINITION_ARN`. + The `?? ECS_TASK_DEFINITION_ARN` fallback keeps it safe if the planning def isn't wired (older + deploy) — it just runs on the build def as today, never worse. +- The session-start guard (`ecs-strategy.ts:100`) stays as-is (it already fails honestly, with a + clear message, when the ECS substrate isn't provisioned at all). + +## 3. What this does NOT change +- **Substrate family routing is unchanged** — an ECS repo still plans on ECS (honors + `orchestrator.ts:242`); an AgentCore repo still plans on AgentCore. This is purely "which ECS task + def," not "which substrate." +- **AgentCore repos are untouched** — the AgentCore project this was verified on + doesn't go near this. +- **No workflow logic changes.** Read-only behaviour is substrate-agnostic; + this only affects the box an ECS-repo planning task runs on. + +## 4. Why it's a separate workstream +- It edits `ecs-agent-cluster.ts`, `agent.ts`, `task-orchestrator.ts`, `ecs-strategy.ts` — all owned + by the ECS-substrate workstream, which carries the context-gated `compute_type=ecs` deploy. +- It resolves a tension in `orchestrator.ts:242` that that workstream authored — so that workstream + should own the change + the sizing call. +- Verifying it requires a `--context compute_type=ecs` deploy (provisions the Fargate substrate). + The dev stack is currently `ComputeSubstrate: agentcore` (no ECS resources), so this is a net-new + infra deploy — appropriately that workstream's call, not a side effect of this one. + +## 5. Verification (done) +1. Deployed with `--context compute_type=ecs` (provisions both task defs). ✅ +2.
