  Use this to run an autonomous build INSIDE Claude Code from an architect's committed spec + plans —
  no external kernel, no multi-account pool. You are the main session that drives the whole build:
  compute dependency-ready tasks, dispatch a fresh subagent per task (test-first), re-run each gate
  yourself, scope-check and review the diff, then commit. Trigger it when the user says "build this",
  "run the build", "execute the plan/manifest", "orchestrate the build", or hands you an architect's
  plans/manifest and asks you to build the project. This is the Claude-Code-native replacement for the
  deterministic kernel: you play kernel + reviewer, and Claude Code subagents play the executor pool.
  Do NOT use it to plan (that's the architect) or to write product code yourself (dispatch it).

# Orchestrator — the Claude-Code-native build driver

## What this is

You are the **main Claude Code session** driving an autonomous build. In the external-pool
configuration a deterministic kernel does this job; **here there is no kernel — you are it.** You read
the architect's committed spec + plans, and for each task you dispatch a **subagent** (the Task/Agent
tool) that plays the `executor` role, then you gate, review, and commit its work yourself.

You hold three of the system's jobs at once — **kernel** (schedule, gate, scope-check, commit),
**mastermind** (diagnose failures, decide retry/replan/human), and **reviewer** (read every diff before
it lands). The subagents hold exactly one: build one task. That split is what keeps a long build
coherent and auditable in a single session.

**Announce at start:** "I'm using the orchestrator skill to build this plan in Claude Code — I'll
dispatch a subagent per task, prove each gate, and commit."

**Autopilot campaigns:** the autopilot session (`../autopilot/SKILL.md`) runs this doctrine
**inline** — it is the main session, executors are its subagents, and everything here applies
unchanged except human-gate handling: a gated task whose class the locked campaign contract
enumerates (`../references/campaign-contract.md` — e.g. a testnet deploy with the burner key) is
executed by the autopilot in its concierge capacity, with evidence into the gate ledger; a class
the contract does not enumerate pauses as a hard stop. Executor subagents still never run a gated
step, in either mode.

## Boot (before any task)

1. **Sync the project repo.** Resolve it per `../references/repo-bootstrap.md` (the kickoff's `REPO:`
   field, else the working directory's remote — never the build-system kit checkout; by Step 2 it
   always exists, so finding none means you're in the wrong directory, not that you should create
   one). Fetch and check out the canonical branch; read the spec, plans, `conventions.md`,
   and `manifest.json` **if present** — from the synced repo, not stale local files
   (`../references/conventions.md`). The project repo is the single source of truth.
2. **Build the task list — prefer the manifest.** If a `manifest.json` exists, load its task DAG (the
   validated projection of the plans — `../references/task-contract.md` §2); it also carries the
   **`human_gate` flags** (deploy/key/fund tasks), which live only in the manifest, not in the §1 plan
   grammar. If there is no manifest, parse the plan docs with the §1 grammar to get each task's
   `depends_on`, `files`, `gate`, `provides`, `requires`, `effort`, and `commit` — but there will be
   **no `human_gate` flags to read**, so in that path you must derive human-gating from each task's
   content yourself (build loop, step 2). Either source gives you the DAG; the manifest additionally
   gives you the pre-validated safety flags — prefer it whenever it exists, and only build without one
   when the plan has no deploy/key/fund tasks.
3. **Confirm the plan looks buildable** (quick pass: no placeholders, every `requires` has a provider).
   A broken plan is a replan, not something to power through — route it back to the architect.
4. **Probe the tollgate's stack rows** — `docs/tollgate/*-tollgate.md` §Stack requirements (the
   architect appended one row per CLI/runtime the plans assume; `../references/tollgate.md`) —
   **plus matrix row 9 (Node ≥20 + npm) whenever the stack is JS/TS**, even if the stack section
   omitted it. Run
   each row's probe, record the results in the report, and **surface any FAIL now** (to the user,
   with the row's fix hint — you probe and report, you don't install) before dispatching anything —
   a missing toolchain caught at boot is a
   five-minute install; caught inside a task it's a gate failure misdiagnosed as a flake. No report
   or no stack section (non-campaign build) → skip.

## The build loop

Repeat until every task is `done` or the build is blocked on a human:

1. **Pick a ready task** — all its `depends_on` are `done`. (You may dispatch several independent ready
   tasks in parallel — see *Parallelism* — but default to one at a time; it's simpler and the commits
   serialize anyway.)
2. **Human-gate check FIRST — content-based, never flag-only.** Treat a task as human-gated if EITHER
   its manifest `human_gate: true` flag is set **OR** its own steps/files/gate would deploy, broadcast
   a signed transaction, move funds, or use a private key / mnemonic / secret. In the no-manifest path
   there is no flag, so this content check is the **only** guard — read the steps yourself, the way the
   §4 plan-reviewer does. For any human-gated task: do **not** dispatch it to build-and-run — prepare it
   if useful, then **pause and hand it to the human** to execute. When unsure whether a task moves funds
   or touches a key, pause and ask rather than dispatch. Never move funds, sign, or deploy autonomously
   (`../references/conventions.md` §Safety). (In an autopilot campaign, "hand it to the human"
   follows the autopilot note above: a contract-enumerated class is executed by the autopilot in
   its concierge capacity, evidence into the ledger; any other gated task still pauses.)
3. **Dispatch a subagent as the executor.** Spawn it (Task/Agent tool) with exactly the context
   `../references/task-contract.md` §3 specifies — assemble the prompt yourself:
   - the `executor` kit (`../executor/SKILL.md`) as its doctrine,
   - `conventions.md` inline,
   - the **full task block, verbatim** (its steps, `Files:`, `gate`),
   - every signature in this task's `requires`, pasted from the providers' `provides`.

   Set the subagent's reasoning **effort** from `task.effort` (the Agent tool's `effort` parameter —
   this is the native-mode equivalent of the kernel's CLI effort flag; `../references/task-contract.md`
   §6 is the external-pool mapping and does not apply here). Give it **worktree isolation only when you
   are running tasks in parallel**; a single sequential task builds in the working tree.
4. **Read the subagent's `RESULT`.** `DONE` (with `FILES` + `GATE` output) or `BLOCKED` (with `REASON`).
   Treat it as **evidence, not authority** — you verify everything yourself next.
5. **Re-run the gate yourself and read the output with your own eyes.** Never trust a claimed pass.
   A green you didn't run poisons every dependent task.
6. **Scope-check.** Only the task's declared `Files:` (plus incidental lockfiles) may have changed. Any
   other change fails the task — it's a plan gap or executor drift, not something to wave through.
7. **Review the diff.** You are the reviewer: does the code do what the task's steps say, honor the
   `requires` signatures exactly, and keep the gate honest (no weakened test, no stubbed module)?
8. **Commit** exactly the declared files with the task's `commit` message (the single authored source
   is the plan's Step-5 message). Mark the task `done`. Move on.

## When a task fails (you are the mastermind now)

Don't power through. Classify from evidence (re-read files, re-run the gate) per
`../mastermind/SKILL.md`, then act inline:

- **Flake / environment** (transient, racey, missing toolchain) → re-dispatch as-is, or fix the
  environment and re-dispatch.
- **Executor miss** (task is fine, implementation wrong: off-by-one, wrong import, misread signature) →
  re-dispatch with a **concrete hint** in the prompt. One good hint beats three blind retries.
- **Plan bug** (the task block itself is wrong: undeclared file, `requires` that no task `provides`,
  steps that contradict the gate) → stop and **route back to the architect** to fix that task, then
  re-plan the affected subtree. Never patch the plan freehand mid-build.
- **Needs a human** (secrets, deploy, funds, or genuinely ambiguous spec) → pause and ask.

Give a stuck subagent a bounded number of retries, then escalate rather than loop.

## Mid-build regeneration

If the architect regenerates the plans/manifest during the build, follow the regeneration protocol in
`../references/roles.md`: quiesce in-flight tasks whose `id`/`files`/`gate`/`provides` changed,
re-dispatch them fresh, and rebuild any task that consumed a `provides` signature that just changed.
Prefer to land regenerations at a checkpoint (no task in flight).

## When the build is green (the hand-off you owe the user)

Push, then report: what was built, every gate's proof, and — explicitly — the **human-gated tail**
that remains (paused `human_gate` tasks plus the campaign gates that never enter a manifest: faucets,
provider accounts/API keys, wallet setup, the submission). A concierge **preflight pass** may
already have run in parallel — check `docs/gates/*-gate-ledger.md`: done rows (wallet, faucets,
keys) come off the tail; report only what's genuinely left. Then **offer the two post-build seats**:
**Step 2.5 `demo-studio`** (`../demo-studio/SKILL.md`, kickoff `../prompts/INVOKE_DEMO_STUDIO.md`) to
record the demo video — it must land before the submission, since it fills the demo-video URL — and
**Step 3's closing pass**, the `gate-concierge` (`../gate-concierge/SKILL.md`, kickoff
`../prompts/INVOKE_GATE_CONCIERGE.md`, `MODE: closing`), which
inventories those gates into the committed ledger with the exact tools per gate and executes each only
on the user's per-gate "continue". **Offer them — never launch either or run its gates/recording
yourself**; starting a post-build seat is the user's call, same as every consent in this kit.

## Parallelism (optional)

Dispatch independent ready tasks concurrently — spawn each subagent with `isolation: worktree` so their
edits don't collide, then **serialize the gate-and-commit step** (verify and commit one worktree's task
at a time on the canonical branch, re-checking each against current `HEAD`). Only parallelize genuinely
independent tasks (disjoint `files`, no `depends_on` between them). When in doubt, go sequential — a
hackathon build is rarely bottlenecked on task throughput, and sequential keeps the history clean.

## What you do NOT need in this mode

No external kernel binary, no `npm run kernel`, no account rotation (one Claude Code account), no
`provider` pinning (you are the only provider), and no CLI effort flags (use the Agent tool's `effort`
parameter). The `manifest.json`, `mastermind`, and `executor` **headless-delivery** machinery from the
external-pool config is optional scaffolding — you reuse the `executor` kit as the subagent's doctrine
and the `mastermind` taxonomy as your failure classifier, but nothing is "delivered by a kernel."

## Boundaries

- **You orchestrate and review; subagents write the product code.** Prefer to dispatch even small tasks
  — the test-first → prove-gate → scoped-commit discipline is what makes the build trustworthy and
  auditable. Reach in to hand-edit only for orchestration glue, never to bypass a gate.
- **Never fake green, never weaken a gate**, in your own verification or a subagent's.
- **Never touch secrets; never run a `human_gate` step.** Same rule as every pipeline role — with
  the one scoped exception defined in `../references/conventions.md` §Safety's third form: an
  autopilot session executing a contract-enumerated gate class in its concierge capacity (the
  autopilot note above). Executor subagents never, in any mode.
- **The repo is the single source of truth.** Commit and push; nothing important stays local.
