Ship feature

Ship Feature

Run the whole feature lifecycle as one supervised loop:

brief ─→ PLAN ─→ BUILD (+MR) ─→ REVIEW ─→ ADDRESS ─→ converged? ──no──┐
                                   ▲                      │            │
                                   └──────────────────────┴── round+1 ─┘
                                                          │yes
                                                          ▼
                                                     MERGE GATE
                                              ask / auto / never

You are the loop supervisor. The stages themselves are the four skills — invoke them, don't re-implement them. Your job is sequencing, state, convergence judgment, and honest exits.

Flags

Parse from $ARGUMENTS (everything that isn't a flag is the brief / plan path):

Flag	Default	Meaning
--merge=ask|auto|never	ask (or SHIP_MERGE_MODE env)	what happens when the loop converges
--max-rounds=N	3	maximum review→address rounds before an honest non-converged exit
--autonomous	off	planner answers its own clarifying questions (recorded as Decisions) instead of asking
--plan=path	—	skip planning; start from an existing plan file
--resume	auto-detected	continue an interrupted loop from its recorded stage and round

State the resolved flags in your first status line so a misparse is caught immediately. Track the loop in your task tracker: plan · build · round 1 (review, address) · … · merge gate.

Loop state — the loop survives its session

A loop that dies with its session (crash, interrupt, context loss) and restarts from zero is not a tool a team can trust. Persist state and make every stage re-entrant:

Write .loop/<feature-slug>.state.json at every stage boundary (entering and leaving a stage). Shape:

{
  "feature": "csv-export", "plan": "docs/plans/2026-07-03-csv-export.md",
  "branch": "feat/csv-export", "mr": "!87",
  "stage": "address", "round": 2, "reviewed_sha": "abc1234",
  "flags": {"merge": "ask", "max_rounds": 3, "autonomous": false},
  "rounds": [{"valid": 3, "partial": 1, "invalid": 2, "verdicts": ["Request changes", "..."]}],
  "started_at": "…", "updated_at": "…"
}

Recommend adding .loop/ to the project's .gitignore — state is transient scaffolding, not history (metrics are recorded separately and durably; see the Ship Report).

On start: if a state file exists for the current branch, say so and resume from its recorded stage and round — --resume just makes the intent explicit. A new brief while stale state exists for a different feature is a fresh loop (leave the old file; its loop can still be resumed on its own branch). Never silently restart a loop from zero when state says it was mid-flight.

Idempotency contracts per stage (what makes resume safe):

• Plan/Build: the plan file and branch are checked before recreating — existing plan + branch with commits means resume, not redo.
• Review: before invoking /mr-review, check the MR for a brief already footered with the current round — present means the round's review is done; skip to address.
• Address: /address-review already never double-posts replies or re-triages resolved threads — safe to re-enter.
• Merge gate: check the MR's actual state first; an MR that is already merged reports merged, it doesn't error.

Stages

Stage 1 — Plan

Invoke /plan-feature with the brief (skip if --plan given and the file exists). This is the loop's one designed human touchpoint at the start: answer the planner's blocking questions now, then walk away. With --autonomous, instruct the planner to convert every would-be question into a recorded default in the Decisions section — the user reviews decisions in the MR instead of answering questions up front.

Stage 2 — Build

Invoke /build-feature with the plan. It branches fresh from main, executes the phases, and ends with the branch pushed and the MR raised (Problem / Solution / Technical details / Review notes). Capture the MR reference — every later stage uses it.

Its two hard stops are real and pass through the loop: an architectural concern pauses everything for the user; a red build ends the run with a report. Don't route around either.

Stage 3 — Review round r

Invoke /mr-review on the MR. External reviewers (whichever of OpenAI / Grok are configured) post their briefs as MR comments. Note each reviewer's verdict line.

Stage 4 — Address round r

Invoke /address-review on the MR. It triages every open comment against the real diff, fixes VALID/PARTIAL findings, dismisses INVALID ones with reasons, pushes, and replies to every thread. Record the round's tally: valid / partial / invalid, and the list of finding titles.

Convergence check — after every round

The loop converges when a full round shows the work is clean:

1. The latest review round produced zero VALID or PARTIAL findings after triage (dismissed-with-reasons findings don't block), or every reviewer's verdict is "No blocking issues"; and
2. every review thread on the MR has been replied to (resolved or explicitly deferred with an owner); and
3. the MR's head pipeline is green (poll glab api "projects/:id/merge_requests/<iid>" → .head_pipeline.status until it settles; a failed pipeline is a red build → hard stop).

Not converged → increment the round and go back to Stage 3, subject to the safeguards below.

Safeguards against thrash:

• Max rounds (--max-rounds, default 3). External reviewers can generate low-value findings forever; three rounds is where returns go negative. Hitting the cap is an honest exit: report what's still open and stop — never merge past it silently.
• No-progress detection. If a finding you fixed in round r comes back in round r+1 (same file/issue), or the valid-finding count doesn't drop between rounds, stop and escalate to the user with both rounds' tallies — the loop is oscillating, and a human call beats a fourth attempt.
• Honest convergence only. Never resolve a thread without a fix or a stated dismissal, never soften a triage verdict, never skip /mr-review "because it'll probably pass" — a loop that games its own exit criteria is worse than no loop.
• Cost awareness. Each round spends reviewer API tokens. Note the round count in the final report so the user sees what convergence cost.

Merge gate — on convergence

First run the readiness checklist (all must hold, whatever the merge mode):

• Converged per the check above (findings clean + threads closed + CI green).
• The MR is mergeable: no conflicts with the target branch (.has_conflicts == false, .merge_status). If the target moved and there are conflicts, stop and report — resolving a conflicted rebase is a human-supervised task, not a loop step.
• Surface the build report's follow-ups (manual migrations to apply, cross-repo deploy order) — merging does not make those happen; they go in the final report either way.

Then act per the flag:

• ask (default): print the Ship Report (below) ending with READY TO MERGE and the exact merge command — then stop. The user merges, or replies "merge it" and you run the command. This is the safe default; auto-merge is opt-in per invocation.
• auto: merge it: glab mr merge <iid> --remove-source-branch (GitHub: gh pr merge <n> --delete-branch, honoring the repo's merge method). Verify the MR state is merged, then report. If the merge API refuses (permissions, approvals required, protected branch rules), report the refusal verbatim — don't try to bypass review requirements.
• never: report and end with the MR open — useful when merging is someone else's call.

Record the run, then report

On every exit — merged, ready, or stopped — append one line to docs/loops/metrics.jsonl, built from the state file:

{"ts":"<iso8601>","type":"run","feature":"csv-export","mr":"!87","outcome":"merged|ready|stopped:<reason>","rounds":2,"lead_time_min":94,"tokens":{"openai":48210,"xai":39102},"flags":{"merge":"ask","max_rounds":3}}

Commit it as docs: record loop metrics when your workflow permits a direct docs commit (append-only JSONL merges trivially); otherwise leave it staged and say so in the report. /loop-stats renders the trends. A loop that doesn't measure itself can't prove it's worth running.

Ship Report (final output, always)

## Ship Report — {feature} (MR !{N})

Outcome: MERGED ✅ | READY TO MERGE (awaiting approval) | STOPPED ({reason})
Loop: plan {✅/skipped} · build ✅ ({n} commits) · {r} review round(s)

Rounds:
  1. {v} valid / {p} partial / {i} invalid → fixed {v+p} · verdicts: {…}
  2. …

Ledgers: hacks {n} · sync points {n} (see MR description / build report)
Follow-ups: {manual migrations + order · deploy sequence · deferred items · none}

Rules

• Orchestrate, don't re-implement. Each stage is its skill, with its skill's rules. If a stage skill is missing, stop and say which one — no inline approximations of it.
• The sub-skills' hard stops are the loop's hard stops. Architectural concern, red build, red pipeline, merge conflicts: all surface to the user immediately. The loop makes routine iteration autonomous; it never makes judgment calls autonomous.
• Merging is gated by the flag, and ask is the default. auto must have been explicitly requested this invocation (or via SHIP_MERGE_MODE) — never assume it, never upgrade to it mid-run, and record in the report which mode ran.
• Exits are honest. Converged, max-rounds, no-progress, or hard stop — the report names which, with what's still open. "Merged" is only claimed after verifying the MR state.
• One feature per loop. Don't batch unrelated briefs into one run; queue them as separate invocations so each MR stays reviewable.
• Keep round outputs terse. The sub-skills print their own detail; the loop supervisor adds one tally line per stage, and the Ship Report at the end.
