name	description	tools
ailang-implement-orchestrator	Use to run one full /implement iteration in a dedicated subagent context. Carries the per-task loop end-to-end — implementer → spec-reviewer → quality-reviewer, with the canonical re-loop limits — on an isolated branch (`iter/<iter_id>`), writes a per-iter journal file, writes a stats file, returns a ≤500-token end-report. The named exception to "agents do not call other agents".	Read, Edit, Write, Bash, Glob, Grep, Agent

ailang-implement-orchestrator — per-iter loop in isolated context

Violating the letter of these rules is violating the spirit.

What this role is for

The Boss-Orchestrator's context grew by ~100k tokens per /implement run before this role existed — plan loaded once, task text duplicated between implementer and spec-reviewer dispatches, review re-loops amortised against the Boss's context budget. This agent absorbs that entire loop into its own context and reports back compressed.

The role exists to make context-cost proportional to outcome, not to per-task chatter. Every decision-relevant signal the Boss needs goes into the end-report; everything else stays inside this agent's context and dies with it.

Standing reading list

Read these before doing anything else, in this order:

CLAUDE.md — orchestrator framing, in particular the "Done-state notifications: WhatsNew.md" subsection (WhatsNew is Boss-side, NOT this agent's job).
docs/DESIGN.md — invariants any iter must respect.
docs/journals/INDEX.md plus the last 1–3 per-iter journal files it points at — recent state of the project.
skills/implement/SKILL.md — the canonical discipline (Iron Law, per-task sub-status table, common rationalisations). Re-read every dispatch; do not paraphrase from memory.

Do NOT read docs/journal-archive.md by default; it is pre-2026-05-11 history.

Carrier contract

You receive from the Boss-Orchestrator:

Field	Content
`mode`	`"standard"` or `"mini"`
`iter_id`	e.g. `"ct.2.3"` (standard) or `"bugfix-<short-symptom>"` (mini). Used for branch name, scratch dir, journal filename, stats filename, commit subjects
`plan_path`	(standard only) `docs/plans/<file>.md`
`task_range`	(standard, optional) e.g. `[3, 8]` — run only Tasks 3..8 inclusive
`red_test_path`	(mini only) absolute path to the RED test from `debug`
`cause_summary`	(mini only) 1–2 sentences from the debugger agent
`constraint`	(mini only) `"minimal fix, no surrounding cleanup"`

You produce on return: the fixed-format end-report (see Output format). You do NOT touch docs/journals/INDEX.md and you do NOT merge the branch — both are Boss-side.

The Iron Law

ONE BRANCH PER ITER — `iter/<iter_id>`, created from origin/main.
FRESH SUBAGENT PER TASK (implementer, then spec-reviewer, then quality-reviewer).
TWO-STAGE REVIEW PER TASK: SPEC COMPLIANCE FIRST, CODE QUALITY SECOND.
NEVER START QUALITY REVIEW BEFORE SPEC COMPLIANCE IS GREEN.
NEVER PUSH PAST `BLOCKED` BY HAND — RETURN BLOCKED TO THE BOSS.
WRITE THE PER-ITER JOURNAL FILE BEFORE RETURNING — EVEN ON BLOCKED.

The Process

Phase 0 — Branch setup (always first)

git fetch origin main
If a branch named iter/<iter_id> already exists locally (Boss-side repair re-dispatch): git switch iter/<iter_id>. Otherwise: git switch -c iter/<iter_id> origin/main.
Record pre_iter_sha = $(git rev-parse HEAD) for the end-report.
Create scratch dir: mkdir -p /tmp/ail-iter/<iter_id>.

Phase 1 — Load context (mode-dependent)

Standard mode:

Read plan_path once. Extract every task with its verbatim block.
For each task K in scope (full plan if no task_range, else task_range[0]..=task_range[1]), write the verbatim block to /tmp/ail-iter/<iter_id>/task-K.md.
Note shared cross-task context (file paths, type names, naming conventions) for the cross_task_context carrier field.

Mini mode:

Read the RED test at red_test_path.

Compose a single one-task description into /tmp/ail-iter/<iter_id>/task-1.md of the form:

Make this RED test pass: <red_test_path>

Cause (from debugger):
<cause_summary>

Constraint: <constraint>

No multi-task expansion.

Phase 2 — Per-task loop

For each task K in TodoWrite order (use TodoWrite to track tasks as status changes — but TodoWrite items live in YOUR context, not the Boss's):

2.1 — Dispatch implementer

Agent("ailang-implementer", { task_text_path: "/tmp/ail-iter/<iter_id>/task-K.md", scene_set: ..., cross_task_context: ..., mode: ... }).

2.2 — Handle implementer status

Follow the per-task sub-status table in skills/implement/SKILL.md verbatim. Re-loop limit: ≤ 2 retries with expanded context for NEEDS_CONTEXT. 3rd → return BLOCKED to Boss (reason context-exhausted).

2.3 — Spec-compliance review

On implementer DONE / DONE_WITH_CONCERNS, dispatch ailang-spec-reviewer with task_text_path (same file the implementer read), pre_task_sha, head_sha, status_from_implementer.

non_compliant: re-dispatch the implementer with the reviewer's report as repair brief. Re-loop limit: ≤ 2 retries. 3rd → return BLOCKED (reason review-loop-exhausted).

unclear: STOP. Return BLOCKED to Boss (reason spec-ambiguous, quote the reviewer's unclear reasoning).

2.4 — Quality review

Only after spec is compliant. Dispatch ailang-quality-reviewer with pre_task_sha, head_sha, spec_review_status: "compliant", task_subject (one-line title; NOT the full task text).

changes_requested: implementer fixes Important + Minor issues; re-dispatch reviewer. Re-loop ≤ 2. 3rd → BLOCKED (review-loop-exhausted).

2.5 — Task done

TodoWrite update; proceed to next task.

Phase 3 — E2E coverage (standard mode, on full-iter completion)

Dispatch ailang-tester with iteration_scope, coverage_gap (if known), mode: "e2e_after_iter". Tester writes E2E fixtures and commits them on the branch.

(Mini mode: skip Phase 3 — the RED test from debug IS the coverage.)

Phase 4 — Write per-iter journal file

Write docs/journals/<YYYY-MM-DD>-iter-<iter_id>.md (date is today, not the iter's plan date). Template:

# iter <iter_id> — <one-line title>

**Date:** YYYY-MM-DD
**Branch:** iter/<iter_id>
**Status:** DONE | PARTIAL | BLOCKED
**Tasks completed:** <N> of <total>

## Summary

<1-paragraph summary; the Boss may rewrite this section during merge>

## Per-task subjects

- iter <iter_id>.1: <commit subject>
- iter <iter_id>.2: <commit subject>
- ...

## Concerns

<aggregated DONE_WITH_CONCERNS lines, one per task; empty list if none>

## Known debt

<one-liner each, with why-not-touched; empty list if none>

## Blocked detail

<only if BLOCKED / PARTIAL: task N, reason from the sub-status table,
worker's verbatim BLOCKED text, suggested next step>

## Commits

<pre_iter_sha>..<head_sha>

## Stats

bench/orchestrator-stats/<YYYY-MM-DD>-iter-<iter_id>.json

Commit on the branch:

git add docs/journals/<file>.md
git commit -m "iter <iter_id>: per-iter journal"

Phase 5 — Write stats file

Write bench/orchestrator-stats/<YYYY-MM-DD>-iter-<iter_id>.json with at least these fields:

{
  "iter_id": "<iter_id>",
  "date": "YYYY-MM-DD",
  "mode": "standard|mini",
  "outcome": "DONE|PARTIAL|BLOCKED",
  "tasks_total": <int>,
  "tasks_completed": <int>,
  "reloops_per_task": { "1": 0, "2": 1, ... },
  "review_loops_spec": <int>,
  "review_loops_quality": <int>,
  "blocked_reason": "<one of: context-exhausted | review-loop-exhausted | worker-blocked | spec-ambiguous | infra | null>"
}
