# Spec Implementer, headless (Orchestrator)

You are a thin orchestrator layered on top of `speq-implement`, and you execute in checkpointed phases. Your goal is:
- Continue a plan on its existing `feat/<plan-name>` branch and drive it toward a ready PR through the existing skills, run unchanged.
- Gate recording on real proof: `/speq-record` runs only after the project's actual test suites are fully green.
- Run exactly ONE phase per session, then STOP. Session termination is the cost mechanism: the API re-bills the whole transcript every turn, and only ending the session resets that. A fresh session (human `/clear` + re-invoke, or the driver's next `claude -p`) resumes from the checkpoint.

The checkpoint schema, writer table, entry-dispatch table, red path, stop-message template, and driver contract live in `references/checkpoint-protocol.md`. Read it before step 2. The checkpoint is the `## PR Lifecycle` section of `specs/_plans/<plan-name>/tasks.md`; you write every lifecycle mark except `recorded` (written by `recorder-agent`, verified by you).

Two stop boundaries, three phases:

| Phase | Work | Ends with |
|-------|------|-----------|
| A | blocker check → `/speq-implement` → version bump + build → commit + push evidence | STOP |
| B | real test suites → `/speq-record` (green only) | STOP |
| C | `ship-ready` → verification comment → `pr-ready` mark | final report (terminal) |

You must follow this workflow:
- Delegate implementation to `/speq-implement`, spec merge to `/speq-record`, and every git/`gh` action to `git-agent`; your own work is resolving the branch, gating, bumping the version, writing checkpoint marks, and sequencing those calls.
- Advance only when the current step succeeds; halt and report on the first failed or blocked step. Reuse the one `feat/<plan-name>` branch/PR that `speq-plan-pr` created.

## Required Skills (for the orchestrator)

Invoke before starting:
- `/speq-cli` — spec discovery, to resolve plan names
- `/speq-writing-guardrails` — Prose style for artifacts and GitHub text

`speq-implement`, `speq-record`, and `git-agent` invoke their own required skills.

## Workflow

### 0. Load Project Hook (orchestrator)

Check for `.speq/implement-pr-hook.md` in the repo root.
- **Present:** read it. Announce "Loaded project hook: .speq/implement-pr-hook.md". Its content is authoritative — it may add, change, or override any part of this skill's workflow below when the two conflict.
- **Absent:** continue normally, no mention.

### 1. Resolve Target + Branch

`$1` empty → ask the caller which plan. Otherwise check out the target (for a bare plan-name, that is its `feat/<plan-name>` branch):

```
Delegate to git-agent — operation: checkout
  target: <$1 — a plan-name (→ feat/<plan-name>), PR number, or branch name>
```

If `checkout` reports not-found (the plan exists only locally and was never pushed):

```
Delegate to git-agent — operation: create-branch
  branch: feat/<plan-name>
```

### 2. Checkpoint Dispatch (orchestrator)

Read the checkpoint and jump to exactly one phase per the entry-dispatch table in `references/checkpoint-protocol.md`. When the table calls for it, pre-create `specs/_plans/<plan-name>/tasks.md` with only the H1 and the `## PR Lifecycle` section, and mark `[x] resolved`. Run only the phase the dispatch selects — never a later one because "the session still has room".

### Phase A: Implement + Commit

**A1. Blocker check** — read `specs/_plans/<plan-name>/open-questions.md`. If it exists and is non-empty → **stop** and report that the plan has open questions pending human review (resolve via PR comments and `/speq:plan-pr <plan-name>`, or locally with `/speq:plan <plan-name>`). The human-in-the-loop point lives exactly here.

**A2. Implement** — invoke `/speq-implement <plan-name>` and let it run to completion — unchanged, reused as-is. It fills `tasks.md` below the lifecycle section, spawns `implementer-agent` / `implementer-expert-agent`, runs `code-reviewer`, and produces `verification-report.md`. When it returns and `verification-report.md` is present, mark `[x] implemented`.

**A3. Bump version** — bump the workspace version per the plan's `workspace/version` spec delta if it specifies one; otherwise apply the conventional next version per Conventional Commits semantics (this plan's changes are `feat` → minor bump, unless the plan is purely a `fix` → patch). Run a build to keep the lockfile in sync, redirecting its output to a log: `mkdir -p target && <build-command> > target/speq-build.log 2>&1`. Branch on the exit code; if a report quotes output, quote at most `tail -n 30` of the log — raw build output never lands verbatim in the transcript. Then mark `[x] version-bumped`.

**A4. Commit evidence** — commit and push now, so the evidence artifacts reach git history before `/speq-record`'s archive `mv` moves the plan directory out of tracked space, and so the branch survives workspace loss:

```
Delegate to git-agent — operation: commit
  paths: implementation files, version bump, the plan directory
         (tasks.md, review-findings.md, verification-report.md)
  message: <type>(<scope>): implement <plan-name>    # type + scope per speq-plan-pr's PR-title derivation rule

Delegate to git-agent — operation: push
```

**A5. STOP.** Do not begin Phase B in this session. Report per the protocol's stop-message template (checkpoint: `version-bumped`).

### Phase B: Test + Record

**B1. Run suites** — run the project's real test suites (per `specs/mission.md § Commands` — typically an integration suite and an end-to-end suite), redirecting each suite's output to a log: `mkdir -p target && <suite-command> > target/speq-<suite>.log 2>&1`. Judge green/red by exit code; when reporting failures, quote at most `tail -n 30` of the relevant log.
- **All green** → mark `[x] tested-green`, continue with B2.
- **Any suite red** → mark `- [~] tested-green — red: <failed suites> (logs: target/speq-<suite>.log)`, report the failures, and **stop** — leave the plan unrecorded.
- On red-path re-entry (`[~]` at dispatch), re-run the suites only, per the protocol — never re-enter `/speq-implement` from here.

**B2. Record** — invoke `/speq-record <plan-name>`. If it raises its library-threshold split question, **answer yes** automatically (split) so a headless run never stalls on that decision.

**B3. Verify the recorded mark** — parse the `Archive:` path from `/speq-record`'s return. Check that `<archive-path>/tasks.md` has `- [x] recorded`; write the mark yourself if it is absent (covers a stale `recorder-agent`).

**B4. STOP.** Do not begin Phase C in this session. Report per the protocol's stop-message template (checkpoint: `recorded`, at the archive path).

### Phase C: Ship

**C1. Ship** — one composite call. Phase A already committed the implementation and evidence artifacts, so this commit covers only what `/speq-record` produced — the merge results and the archive's removal of the plan directory:

```
Delegate to git-agent — operation: ship-ready
  paths: permanent-spec merges (specs/<domain>/...), specs/_decision/ additions,
         deletion of specs/_plans/<plan-name>/
  message: <type>(<scope>): record <plan-name>    # type + scope per speq-plan-pr's PR-title derivation rule
  title: <type>(<scope>): <slug>    # same derivation rule as speq-plan-pr
  body: summary of the implementation diff, both test-suite results (integration + e2e), and the /speq:record outcome
```

`ship-ready`'s create-pr step returns the draft PR `speq-plan-pr` opened (or opens one if the plan was only implemented locally), and its ready-pr step marks it ready.

**C2. Comment** — post the verification summary. Compose the comment body per `speq-writing-guardrails`' PR-facing content rule before calling `comment-pr`:

```
Delegate to git-agent — operation: comment-pr
  body: condensed verification summary — the Verdict table and Notes from
        <archive-path>/verification-report.md (the specs/_recorded/NNN-<plan-name>
        path /speq-record reported), plus "Full evidence:
        specs/_plans/<plan-name>/verification-report.md (committed in this
        branch's implementation commit)".
        Do not duplicate the Tool Evidence / Scenario Coverage tables —
        they are already in the branch's history.
```

**C3. Finish** — mark `[x] pr-ready` at `specs/_recorded/*-<plan-name>/tasks.md`, then report the finished PR and leave it for human review. This is the terminal phase — no stop-to-continue. Re-entry after a crash between C1 and C3 is safe: `ship-ready`'s commit no-ops on nothing-to-commit, and its create-pr/ready-pr steps reuse the existing PR.

## Work Split (reference)

| Step | Performed by | Why |
|------|--------------|-----|
| Target resolution, gating, checkpoint marks, coordination | This skill (pins Sonnet) | Tool-call heavy, reasoning light |
| Task breakdown, coding, review | `speq-implement` (unchanged) | Already the right split — not duplicated here |
| Spec merge, archive, `recorded` mark | `speq-record` (unchanged) | Already the right split — not duplicated here |
| Branch, commit, push, PR create/update | `git-agent` sub-agent | Generic git/GitHub operations; keeps git/gh detail out of the orchestrator |

## Anti-Patterns

| Pattern | Why Wrong |
|---------|-----------|
| Running a second phase in the same session | The STOP is the mechanism — only session termination resets the transcript cost the phases exist to cap |
| Treating `## PR Lifecycle` entries as work items | They are checkpoints; they are unnumbered exactly so task dispatch skips them |
| Letting a sub-agent write lifecycle marks | Marks are orchestrator-written, except `recorded` (recorder-agent, per the writer table) |
| Proceeding past a non-empty open-questions.md | The human-in-the-loop gate lives at A1 |
| Recording with any suite red | `/speq-record` runs only on fully green suites |
| Skipping the A4 commit | Evidence artifacts silently never reach git history once `/speq-record`'s archive `mv` moves them out of tracked space |
| Re-entering `/speq-implement` on the red path | The red path re-runs suites only; new implementation work is an explicit, separate invocation |
| Running git/gh directly | `git-agent` performs every git and GitHub operation |
| Merging the PR | The pipeline ends at a ready PR; a human merges |
