ship

# Ship Command

You help ship code by creating commits, pushing to the remote branch, and creating PRs in the user's voice.

## Your Task

When the user runs `/ship`:

1. **Check git status** - See what files have changed
2. **Sync check**: `git fetch origin staging && git log --oneline origin/staging..HEAD`. Read the actual commit list, not just how many there are — it must show ONLY commits you can attribute to this session (recognizable subjects/SHAs). A worktree/branch can silently be cut from a stale local `staging`, dragging in unrelated commits; a corrupted branch's inflated commit *count* can coincidentally match a later check even when the *commits* are wrong, so always compare content, never just a number.
   - If it shows commits you don't recognize, fix it now, **before** staging/committing any new work (step 7 hasn't run yet):
     - If the working tree has uncommitted changes, stash them first — `git stash push -u -m ship-sync-fix` — so the rebase below isn't blocked by dirty state. Restore with `git stash pop` once the branch is fixed.
     - Try `git rebase origin/staging` first.
     - **A rebase finishing without conflicts does NOT by itself mean the branch is clean** — it can replay stray commits onto the new base with no conflict at all. After the rebase (clean or not), re-run `git log --oneline origin/staging..HEAD` and re-check the commit list against what you recognize.
     - If the rebase conflicted on commits you don't recognize, OR it finished cleanly but the re-checked log still shows commits you don't recognize, abandon that result (`git rebase --abort` if still mid-rebase) and rebuild instead, in this exact order:
       1. **While still on `<original-branch>`**, identify the SHA(s) to preserve — **not** the whole range. `git log --oneline --reverse origin/staging..<original-branch>` lists everything ahead of `origin/staging`, but in exactly this scenario that range also contains the unrecognized/stray commits you're trying to leave behind — blindly cherry-picking the full range recreates the same polluted branch. Read the list and write down only the SHA(s) you recognize as your own session's work (e.g. `abc1234 def5678`); do this *before* touching any temp branch, since once you check out `ship-sync-tmp` at `origin/staging` in step 4, `HEAD` no longer contains these commits and the same lookup at that point returns nothing.
       2. `git checkout <original-branch>` — harmless no-op if you're already there, but required if an earlier interrupted attempt left you sitting on `ship-sync-tmp`: git refuses to delete the branch you're currently on, so deleting it before switching away silently fails and blocks the rest of the rebuild.
       3. Delete any leftover from an earlier attempt: `git branch -D ship-sync-tmp 2>/dev/null || true` — always succeeds, including when there's nothing to delete (a first attempt), so it never blocks the rest of the rebuild on its own exit code.
       4. `git checkout -b ship-sync-tmp origin/staging`.
       5. `git cherry-pick` the SHAs captured in step 1, **in that oldest-first order** — cherry-picking more than one session commit out of order can fail or produce the wrong history. Resolve conflicts.
       6. `git branch -f <original-branch> HEAD`, `git checkout <original-branch>`, and delete `ship-sync-tmp` (`git branch -D ship-sync-tmp`).
   - Re-verify with `git log --oneline origin/staging..HEAD` — it must list only commits you recognize before you proceed to committing new work.
3. **Generate a commit message** following this format: `type(scope): description`
  - Types: `fix`, `feat`, `improvement`, `chore`
  - Scope: short identifier (e.g., `undo-redo`, `api`, `ui`)
  - Keep it concise
4. **Run the cleanup pass** — only if the diff modifies UI code (any `.tsx` file, or anything under `apps/sim/components/`, `apps/sim/hooks/`, or `apps/sim/stores/`): `/cleanup`
  - The six code-quality skills (effects, memo, callbacks, state, React Query, emcn) only apply to React code, so skip this step entirely when no UI was touched. When it runs, it applies fixes so they land in this commit.
5. **Run migration safety** — only if the diff touches `packages/db/migrations/**` or `packages/db/schema.ts`:
  - Run `/db-migrate` to review the migration for zero-downtime safety (expand/contract phasing, backward-compatibility with the deployed app version).
  - `bun run check:migrations origin/staging` must pass (staging is the PR base). Do not silence a flagged statement with a `-- migration-safe:` annotation unless `/db-migrate` confirmed the old code no longer depends on it; otherwise split the destructive change into a later deploy.
6. **Run pre-ship checks** from the repo root before staging. This has two phases: first **regenerate** every committed artifact so generated files never drift into a CI failure (this is what catches things like `agent-stream-docs` going stale after a `models.ts` edit), then run the **full audit suite** CI's `Lint and Test` job enforces. Both phases parallelize — but only across commands that write **disjoint** outputs — and a bare `wait` swallows child exit codes, so both phases below explicitly collect each job's status and abort ship if any failed.

  **Phase A — regenerate the always-in-repo committed artifacts (parallel), then let step 7 stage whatever changed.** Regenerate only the generators whose inputs live entirely in this repo and that any ordinary code change can drift — `agent-stream-docs:generate` (derives from the provider model registry) and `skills:sync` (derives from `.agents/skills/**`). They write disjoint trees (`apps/docs/…/agent.mdx` vs the `.claude`/`.cursor` command projections), so they parallelize safely, and each is idempotent (a no-op when already in sync):
  ```bash
  rm -f /tmp/ship-gen-results
  for g in agent-stream-docs:generate skills:sync; do
    ( bun run "$g" >"/tmp/ship-gen-${g//:/-}.log" 2>&1; echo "$? $g" >>/tmp/ship-gen-results ) &
  done
  wait
