Ship Loop Pr

ship-loop-pr — push + open PR child loop

Activation

• Standalone: /loop ship-loop-pr (manual push from CEO)
• Orchestrated: invoked by ship-loop-master when:
  • All five inner layers green (build, test, sanity, watch, smoke)
  • git status --short shows staged or unstaged changes (something to push)
  • pr.state === 'not_opened'

Pre-flight (refuse to run if any fail)

1. git rev-parse --abbrev-ref HEAD — branch name. If main or master, refuse with ## P0 — ship-loop-pr refused: branch is main and exit
2. git status --short — if empty, write {"reason":"clean_tree","skipped":true} and return without changing PR state
3. gh auth status — must be authenticated
4. Read state file — confirm all five inner layers green; refuse if any red

Process

Step 1: Stage + commit if needed

If git status --short shows unstaged changes:

• Stage only files relevant to current work (refuse git add -A to avoid grabbing accidental scratchpad files; use explicit paths from git diff --name-only)
• If no commit yet on this branch (HEAD === origin/main): create commit
• Commit message templated from:
  • Linear ticket from state (SYN-XXX)
  • List of changed file paths (top 5)
  • Pre-gate results summary (build/test/sanity/smoke all green)

fix(<scope>): <SYN-XXX> — <ticket title>

Files changed:
<top 5 file paths>

Verification:
- npm run type-check → 0 errors
- npm run lint → 0 errors
- npm test → <X> passed / 0 failed
- npm run build → ✓ Compiled successfully
- npm audit --omit=dev → 0 HIGH

Tracked: <SYN-XXX>

Step 2: Push

git push -u origin <branch>

If rejected with non-fast-forward:

• git fetch origin
• git rebase origin/<branch>
• If rebase has conflicts: STOP, escalate ## P1 — Rebase conflict on push, do NOT push, do NOT force
• If rebase clean: re-attempt push (one retry only)

Step 3: Open PR

gh pr create --repo CleanExpo/Synthex \
  --title "<title from commit>" \
  --body "$(cat <<'EOF'
## Summary
<bulleted summary from commit message>

## Verification
<gate results from state file>

## Linear
<SYN-XXX>

)"

If gh pr create returns "pull request already exists for branch":

• gh pr view --json url,number to capture existing PR
• Update state with the existing URL/number
• Skip create (treat as success)

Step 4: Update state

Atomic update to layers.pr:

{
  "state": "opened",
  "url": "https://github.com/CleanExpo/Synthex/pull/<num>",
  "number": <num>,
  "opened_at": "<iso>",
  "ci_state": "pending",
  "branch": "<branch>"
}

The ci_state will be polled by master loop on subsequent ticks via gh pr checks <num> (master invokes a quick check rather than re-firing this skill — efficient).

Recipe priorities for this loop

• #11 (non-fast-forward) — rebase + retry
• #12 (PR already exists) — capture existing URL, skip create

Hard rules compliance

• No force push — even on rebase conflict, never git push --force. Conflicts escalate.
• No git add -A — explicit file paths only, prevents accidental commit of scratchpad outputs
• No push from main — pre-flight refuses
• Commit messages cite Linear ticket — required by CLAUDE.md hard rule

Verification

• Run on a clean branch with one staged commit; expect successful push + PR open
• Run on clean tree (no changes); expect skip with reason
• Run on main; expect P0 escalation refusal
• Run with sanity layer red in state; expect skip (master shouldn't have invoked, but defense-in-depth)

Out of scope

• PR review request (gh pr edit --add-reviewer) — separate skill if needed
• PR template enforcement — relies on existing .github/pull_request_template.md if present
• Auto-tagging issues / setting milestones / setting projects on the PR — defer to senior-pm skill or Linear's GitHub integration
