Run Loop

Drive the documentation chain end-to-end without per-task prompting. You are the producer; verification is dispatched to a fresh-context verifier, never self-graded; merging is never yours.

Target

Parse the user's instruction:

• A milestone (e.g. M2) → run its tasks in dependency order until the milestone is done
• A task ID (e.g. M2-T3) → run exactly that task
• until-blocked → keep taking the next unblocked task until nothing is runnable
• max-tasks=N → cap on tasks this run (default 5; the user must raise it explicitly for longer runs)

No target given → ask for one before looping. Do not guess.

Preconditions — abort with a clear message if unmet

1. AGENTS.md, docs/plans/implementation-plan.md, and docs/status.md exist. If not, stop and route to the using-agentic-engineering router — a loop without the chain is just unsupervised guessing.
2. Working tree is clean and main is up to date.
3. The In-Flight Checkpoint in docs/status.md is none. If it isn't, the previous session crashed — run the status-tracker recovery protocol first, then loop.

Loop body — per task

1. Pick the next unblocked task for the target (STATUS module table + plan dependency order).
2. Branch per the git-workflow skill: task/<task-id>-<slug> from up-to-date main.
3. Build to the spec. Producer self-check: lint clean, full suite passing, test ratchet holds.
4. Checkpoint docs/status.md: In-Flight Checkpoint updated, module table → 🔍.
5. Ship: push the branch, open a draft PR whose description carries the task reference and done condition (git-workflow PR protocol).
6. Verify: dispatch a fresh-context verifier with the task ID, branch name, and done-condition location — the bundled verifier sub-agent where the harness supports it, otherwise any fresh-context mechanism per the independent-verification skill (a fresh session or separate agent). Never verify your own work in this conversation.
7. On PASS: STATUS module table → ✅ with verdict + PR references; flip the PR from draft to ready; proceed to the next task.
8. On FAIL: fix on the same branch (each round noted in the PR), re-dispatch the verifier. Three consecutive FAILs on one task stops the entire loop — escalate to the user with the verdict history.

Stop conditions — whichever comes first

• Target reached
• Circuit breaker: 3 consecutive FAILs on one task
• max-tasks budget spent
• No unblocked tasks remain
• A precondition broke mid-run (e.g. the tree turned dirty outside your work)

Wind-down — always, even on abort

1. Finalize docs/status.md: module table, header block, handoff log entry; In-Flight Checkpoint reset to none.
2. Report: tasks completed (with PR + verdict references), tasks failed (with the last verdict), tasks remaining, and exactly where and why the loop stopped.

Hard rules

• Never merge. The loop's output is a queue of verified draft→ready PRs. Merging belongs to the human gate, after a human has read each diff.
• Never weaken a done condition to make the loop converge — that is escalation, not negotiation.
• Checkpoint before every risky step. A crash must cost at most one task.
• AGENTS.md boundaries apply to every iteration — the loop is not a license to skip the chain.
