# Ship: Fully Automated Ship Workflow

You are running the `/ship` workflow. This is a **non-interactive, fully automated** workflow. Do NOT ask for confirmation at any step. The user said `/ship` which means DO IT. Run straight through and output the PR URL at the end.

**Only stop for:**
- On the base branch (abort)
- Merge conflicts that can't be auto-resolved (stop, show conflicts)
- In-branch test failures (pre-existing failures are triaged, not auto-blocking)
- Pre-landing review finds ASK items that need user judgment
- MINOR or MAJOR version bump needed (ask — see Step 12)
- Greptile review comments that need user decision (complex fixes, false positives)
- AI-assessed coverage below minimum threshold (hard gate with user override — see Step 7)
- Plan items NOT DONE with no user override (see Step 8)
- Plan verification failures (see Step 8.1)
- TODOS.md missing and user wants to create one (ask — see Step 14)
- TODOS.md disorganized and user wants to reorganize (ask — see Step 14)

**Never stop for:**
- Uncommitted changes (always include them)
- Version bump choice (auto-pick MICRO or PATCH — see Step 12)
- CHANGELOG content (auto-generate from diff)
- Commit message approval (auto-commit)
- Multi-file changesets (auto-split into bisectable commits)
- TODOS.md completed-item detection (auto-mark)
- Auto-fixable review findings (dead code, N+1, stale comments — fixed automatically)
- Test coverage gaps within target threshold (auto-generate and commit, or flag in PR body)

**Re-run behavior (idempotency):**
Re-running `/ship` means "run the whole checklist again." Every verification step
(tests, coverage audit, plan completion, pre-landing review, adversarial review,
VERSION/CHANGELOG check, TODOS, document-release) runs on every invocation.
Only *actions* are idempotent:
- Step 12: If VERSION already bumped, skip the bump but still read the version
- Step 17: If already pushed, skip the push command
- Step 19: If PR exists, update the body instead of creating a new PR
Never skip a verification step because a prior `/ship` run already performed it.

## Step 0.9: Apple target detection

Shipping to the App Store is not landing a PR. If the repository contains an
`.xcodeproj`, `.xcworkspace`, or a Swift package with an app product AND the
user's ask is store distribution (App Store, TestFlight, "release my app"),
**STOP and Read `~/.claude/skills/gstack/ship/sections/apple-release.md` FIRST**
— before the branch gate and any preflight below. Store distribution proceeds
from whatever branch the user is on (a clean tree on the base branch is the
solo developer's normal case, not an error) and follows the adapter end to
end. The branch gate and repository-landing pipeline below apply ONLY to
repository-landing asks, including on Apple repos.

## Step 1: Pre-flight

1. Check the current branch. If on the base branch or the repo's default branch, **abort**: "You're on the base branch. Ship from a feature branch."

2. Run `git status` (never use `-uall`). Uncommitted changes are always included — no need to ask.

3. Run `git diff <base>...HEAD --stat` and `git log <base>..HEAD --oneline` to understand what's being shipped.

4. Check review readiness:

{{REVIEW_DASHBOARD}}

If the Eng Review is NOT "CLEAR":

Print: "No prior eng review found — ship will run its own pre-landing review in Step 9."

Check diff size: `git diff <base>...HEAD --stat | tail -1`. If the diff is >200 lines, add: "Note: This is a large diff. Consider running `/plan-eng-review` or `/autoplan` for architecture-level review before shipping."

If CEO Review is missing, mention as informational ("CEO Review not run — recommended for product changes") but do NOT block.

For Design Review: run `source <(~/.claude/skills/gstack/bin/gstack-diff-scope <base> 2>/dev/null)`. If `SCOPE_FRONTEND=true` and no design review (plan-design-review or design-review-lite) exists in the dashboard, mention: "Design Review not run — this PR changes frontend code. The lite design check will run automatically in Step 9, but consider running /design-review for a full visual audit post-implementation." Still never block.

Continue to Step 2 — do NOT block or ask. Ship runs its own review in Step 9.

---

## Step 2: Distribution Pipeline Check

If the diff introduces a new standalone artifact (CLI binary, library package, tool) — not a web
service with existing deployment — verify that a distribution pipeline exists.

1. Check if the diff adds a new `cmd/` directory, `main.go`, or `bin/` entry point:
   ```bash
   git diff origin/<base> --name-only | grep -E '(cmd/.*/main\.go|bin/|Cargo\.toml|setup\.py|package\.json)' | head -5
   ```

2. If new artifact detected, check for a release workflow:
   ```bash
   ls .github/workflows/ 2>/dev/null | grep -iE 'release|publish|dist'
   grep -qE 'release|publish|deploy' .gitlab-ci.yml 2>/dev/null && echo "GITLAB_CI_RELEASE"
   ```

3. **If no release pipeline exists and a new artifact was added:** Use AskUserQuestion:
   - "This PR adds a new binary/tool but there's no CI/CD pipeline to build and publish it.
     Users won't be able to download the artifact after merge."
   - A) Add a release workflow now (CI/CD release pipeline — GitHub Actions or GitLab CI depending on platform)
   - B) Defer — add to TODOS.md
   - C) Not needed — this is internal/web-only, existing deployment covers it

4. **If release pipeline exists:** Continue silently.
5. **If no new artifact detected:** Skip silently.

---

## Step 3: Merge the base branch (BEFORE tests)

Fetch and merge the base branch into the feature branch so tests run against the merged state:

```bash
git fetch origin <base> && git merge origin/<base> --no-edit
```

**If there are merge conflicts:** Try to auto-resolve if they are simple (VERSION, schema.rb, CHANGELOG ordering). If conflicts are complex or ambiguous, **STOP** and show them.

**If already up to date:** Continue silently.

## Step 12: Version bump (auto-decide)

The deterministic version-state logic is the tested **`gstack-version-bump`** CLI
(classify / write / repair). The bump-LEVEL decision and queue-collision handling
stay agent judgment; the slot pick stays `gstack-next-version`.

1. **Classify state** — pure reader, never writes:
   ```bash
   bun run ~/.claude/skills/gstack/bin/gstack-version-bump classify --base <base>
   ```
   Read the JSON `state` and dispatch:
   - **FRESH** → do the bump (steps 2-4).
   - **ALREADY_BUMPED** → skip the bump, but run the queue-drift check (step 3) with the reported `currentVersion`. If the queue moved (next free version differs), **AskUserQuestion**: rebump to the new version (rewrites CHANGELOG header + PR title) or keep current (CI version-gate will reject until resolved).
   - **DRIFT_STALE_PKG** → run `gstack-version-bump repair` (syncs package.json to VERSION). No re-bump; reuse `currentVersion` for CHANGELOG + PR.
   - **DRIFT_UNEXPECTED** → **STOP**. package.json disagrees with VERSION while VERSION matches base — a manual edit bypassed /ship. Reconcile manually, then re-run.

2. **Decide the bump level** from the diff (agent judgment):
   - **MICRO**: <50 lines, trivial tweaks/config. **PATCH**: 50+ lines, no feature signals.
   - **MINOR**: **ASK** if any feature signal (new route/page, migration, new module), OR 500+ lines. **MAJOR**: **ASK** — milestones or breaking changes only.
   Save as `BUMP_LEVEL`. The level is the user-intended bump; queue-aware placement may advance the slot without changing the level.

3. **Queue-aware pick** (workspace-aware ship):
   ```bash
   QUEUE_JSON=$(bun run ~/.claude/skills/gstack/bin/gstack-next-version --base <base> --bump "$BUMP_LEVEL" --current-version "$BASE_VERSION" 2>/dev/null || echo '{"offline":true}')
   NEW_VERSION=$(echo "$QUEUE_JSON" | jq -r '.version // empty')
   ```
   If `offline`/util fails: fall back to local `BUMP_LEVEL` arithmetic and print `⚠ workspace-aware ship offline — using local bump only`. If `claimed` is non-empty, render the queue table so the user sees landing order. If an active sibling workspace holds a version `>= NEW_VERSION`, **AskUserQuestion**: advance past (unrelated work) or abort and sync with the sibling.

4. **Write the bump** (FRESH, or an approved rebump):
   ```bash
   bun run ~/.claude/skills/gstack/bin/gstack-version-bump write --version "$NEW_VERSION"
   ```
   The CLI validates the 4-digit `MAJOR.MINOR.PATCH.MICRO` pattern and writes **both** VERSION and package.json. On a half-write (VERSION written, package.json failed) it exits 3 — re-run, and classify will report DRIFT_STALE_PKG for `repair` to fix.

5. **Record the release decision** (durable cross-session memory). The bump level is a real decision the next session should not re-derive blind:
   ```bash
   ~/.claude/skills/gstack/bin/gstack-decision-log '{"decision":"Ship NEW_VERSION (BUMP_LEVEL)","rationale":"WHY","scope":"repo","source":"skill","confidence":9}' 2>/dev/null || true
   ```
   Substitute `NEW_VERSION`, `BUMP_LEVEL`, and a one-line `WHY` (the signal that set the level: diff scale, a new feature, a breaking change). Best-effort and non-interactive; never blocks the ship. Skip on the ALREADY_BUMPED path (the decision was logged on the run that did the bump).

{{SECTION:changelog}}

## Step 14: TODOS.md (auto-update)

Cross-reference the project's TODOS.md against the changes being shipped. Mark completed items automatically; prompt only if the file is missing or disorganized.

Read `.claude/skills/review/TODOS-format.md` for the canonical format reference.

**1. Check if TODOS.md exists** in the repository root.

**If TODOS.md does not exist:** Use AskUserQuestion:
- Message: "GStack recommends maintaining a TODOS.md organized by skill/component, then priority (P0 at top through P4, then Completed at bottom). See TODOS-format.md for the full format. Would you like to create one?"
- Options: A) Create it now, B) Skip for now
- If A: Create `TODOS.md` with a skeleton (# TODOS heading + ## Completed section). Continue to step 3.
- If B: Skip the rest of Step 14. Continue to Step 15.

**2. Check structure and organization:**

Read TODOS.md and verify it follows the recommended structure:
- Items grouped under `## <Skill/Component>` headings
- Each item has `**Priority:**` field with P0-P4 value
- A `## Completed` section at the bottom

**If disorganized** (missing priority fields, no component groupings, no Completed section): Use AskUserQuestion:
- Message: "TODOS.md doesn't follow the recommended structure (skill/component groupings, P0-P4 priority, Completed section). Would you like to reorganize it?"
- Options: A) Reorganize now (recommended), B) Leave as-is
- If A: Reorganize in-place following TODOS-format.md. Preserve all content — only restructure, never delete items.
- If B: Continue to step 3 without restructuring.

**3. Detect completed TODOs:**

This step is fully automatic — no user interaction.

Use the diff and commit history already gathered in earlier steps:
- `git diff <base>...HEAD` (full diff against the base branch)
- `git log <base>..HEAD --oneline` (all commits being shipped)

For each TODO item, check if the changes in this PR complete it by:
- Matching commit messages against the TODO title and description
- Checking if files referenced in the TODO appear in the diff
- Checking if the TODO's described work matches the functional changes

**Be conservative:** Only mark a TODO as completed if there is clear evidence in the diff. If uncertain, leave it alone.

**4. Move completed items** to the `## Completed` section at the bottom. Append: `**Completed:** vX.Y.Z (YYYY-MM-DD)`

**5. Output summary:**
- `TODOS.md: N items marked complete (item1, item2, ...). M items remaining.`
- Or: `TODOS.md: No completed items detected. M items remaining.`
- Or: `TODOS.md: Created.` / `TODOS.md: Reorganized.`

**6. Defensive:** If TODOS.md cannot be written (permission error, disk full), warn the user and continue. Never stop the ship workflow for a TODOS failure.

Save this summary — it goes into the PR body in Step 19.

---

## Step 15: Commit (bisectable chunks)

### Step 15.0: WIP Commit Squash (continuous checkpoint mode only)

If `CHECKPOINT_MODE` is `"continuous"`, the branch likely contains `WIP:` commits
from auto-checkpointing. These must be squashed INTO the corresponding logical
commits before the bisectable-grouping logic in Step 15.1 runs. Non-WIP commits
on the branch (earlier landed work) must be preserved.

**Detection:**
```bash
WIP_COUNT=$(git log <base>..HEAD --oneline --grep="^WIP:" 2>/dev/null | wc -l | tr -d ' ')
echo "WIP_COMMITS: $WIP_COUNT"
```

If `WIP_COUNT` is 0: skip this sub-step entirely.

If `WIP_COUNT` > 0, collect the WIP context first so it survives the squash:

```bash
# Export [gstack-context] blocks from all WIP commits on this branch.
# This file becomes input to the CHANGELOG entry and may inform PR body context.
mkdir -p "$(git rev-parse --show-toplevel)/.gstack"
git log <base>..HEAD --grep="^WIP:" --format="%H%n%B%n---END---" > \
  "$(git rev-parse --show-toplevel)/.gstack/wip-context-before-squash.md" 2>/dev/null || true
```

**Non-destructive squash strategy:**

`git reset --soft <merge-base>` WOULD uncommit everything including non-WIP commits.
DO NOT DO THAT. Instead, use `git rebase` scoped to filter WIP commits only.

Option 1 (preferred, if there are non-WIP commits mixed in):
```bash
# Interactive rebase with automated WIP squashing.
# Mark every WIP commit as 'fixup' (drop its message, fold changes into prior commit).
git rebase -i $(git merge-base HEAD origin/<base>) \
  --exec 'true' \
  -X ours 2>/dev/null || {
    echo "Rebase conflict. Aborting: git rebase --abort"
    git rebase --abort
    echo "STATUS: BLOCKED — manual WIP squash required"
    exit 1
  }
```

Option 2 (simpler, if the branch is ALL WIP commits so far — no landed work):
```bash
# Branch contains only WIP commits. Reset-soft is safe here because there's
# nothing non-WIP to preserve. Verify first.
NON_WIP=$(git log <base>..HEAD --oneline --invert-grep --grep="^WIP:" 2>/dev/null | wc -l | tr -d ' ')
if [ "$NON_WIP" -eq 0 ]; then
  git reset --soft $(git merge-base HEAD origin/<base>)
  echo "WIP-only branch, reset-soft to merge base. Step 15.1 will create clean commits."
fi
```

Decide at runtime which option applies. If unsure, prefer stopping and asking the
user via AskUserQuestion rather than destroying non-WIP commits.

**Anti-footgun rules:**
- NEVER blind `git reset --soft` if there are non-WIP commits. Codex flagged this
  as destructive — it would uncommit real landed work and turn the push step into
  a non-fast-forward push for anyone who already pushed.
- Only proceed to Step 15.1 after WIP commits are successfully squashed/absorbed
  or the branch has been verified to contain only WIP work.

### Step 15.1: Bisectable Commits

**Goal:** Create small, logical commits that work well with `git bisect` and help LLMs understand what changed.

1. Analyze the diff and group changes into logical commits. Each commit should represent **one coherent change** — not one file, but one logical unit.

2. **Commit ordering** (earlier commits first):
   - **Infrastructure:** migrations, config changes, route additions
   - **Models & services:** new models, services, concerns (with their tests)
   - **Controllers & views:** controllers, views, JS/React components (with their tests)
   - **VERSION + CHANGELOG + TODOS.md:** always in the final commit

3. **Rules for splitting:**
   - A model and its test file go in the same commit
   - A service and its test file go in the same commit
   - A controller, its views, and its test go in the same commit
   - Migrations are their own commit (or grouped with the model they support)
   - Config/route changes can group with the feature they enable
   - If the total diff is small (< 50 lines across < 4 files), a single commit is fine

4. **Each commit must be independently valid** — no broken imports, no references to code that doesn't exist yet. Order commits so dependencies come first.

5. Compose each commit message:
   - First line: `<type>: <summary>` (type = feat/fix/chore/refactor/docs)
   - Body: brief description of what this commit contains
   - Only the **final commit** (VERSION + CHANGELOG) gets the version tag and co-author trailer:

```bash
git commit -m "$(cat <<'EOF'
chore: bump version and changelog (vX.Y.Z.W)

{{CO_AUTHOR_TRAILER}}
EOF
)"
```

---

## Step 16: Verification Gate

**IRON LAW: NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE.**

Before pushing, re-verify if code changed during Steps 4-6:

1. **Test verification:** If ANY code changed after Step 5's test run (fixes from review findings, CHANGELOG edits don't count), re-run the test suite. Paste fresh output. Stale output from Step 5 is NOT acceptable.

2. **Build verification:** If the project has a build step, run it. Paste output.

3. **Rationalization prevention:**
   - "Should work now" → RUN IT.
   - "I'm confident" → Confidence is not evidence.
   - "I already tested earlier" → Code changed since then. Test again.
   - "It's a trivial change" → Trivial changes break production.

**If tests fail here:** STOP. Do not push. Fix the issue and return to Step 5.

Claiming work is complete without verification is dishonesty, not efficiency.

---

## Step 17: Push

**Credential pre-push guard (#1946) — run before the push:**

```bash
_REDACT_PREPUSH=$(~/.claude/skills/gstack/bin/gstack-config get redact_prepush_hook 2>/dev/null || echo "false")
_HOOK_PATH=$(git rev-parse --git-path hooks/pre-push 2>/dev/null || echo "")
_HOOK_INSTALLED="no"
[ -n "$_HOOK_PATH" ] && [ -f "$_HOOK_PATH" ] && grep -q "gstack-redact" "$_HOOK_PATH" 2>/dev/null && _HOOK_INSTALLED="yes"
# Custom hooks dirs (core.hooksPath — e.g. husky's COMMITTED .husky/) must
# never get a silent install: the chaining installer would rename the team's
# committed hook and write a machine-local wrapper into the working tree.
_HOOKS_DIR=$(git rev-parse --git-path hooks 2>/dev/null || echo "")
_GIT_DIR=$(git rev-parse --absolute-git-dir 2>/dev/null || echo "")
# Linked worktrees: --absolute-git-dir is .git/worktrees/<name> but hooks
# resolve to the COMMON .git/hooks, so match against the common dir too or
# every Conductor worktree false-negatives as a "custom hooks path". The
# /nonexistent fallback keeps the case pattern from collapsing to "/*"
# (match-everything) when resolution fails.
_GIT_COMMON=$(cd "$(git rev-parse --git-common-dir 2>/dev/null || echo /nonexistent)" 2>/dev/null && pwd || echo /nonexistent)
_HOOKS_IN_GIT_DIR="no"
case "$_HOOKS_DIR" in
  "$_GIT_DIR"/*|"$_GIT_COMMON"/*|hooks|.git/hooks) _HOOKS_IN_GIT_DIR="yes" ;;
esac
_PREPUSH_PROMPTED=$([ -f "${GSTACK_HOME:-$HOME/.gstack}/.redact-prepush-prompted" ] && echo "yes" || echo "no")
echo "REDACT_PREPUSH: $_REDACT_PREPUSH"
echo "HOOK_INSTALLED: $_HOOK_INSTALLED"
echo "HOOKS_IN_GIT_DIR: $_HOOKS_IN_GIT_DIR"
echo "PREPUSH_PROMPTED: $_PREPUSH_PROMPTED"
```

Branch on the echoed values:

1. **`REDACT_PREPUSH: true` and `HOOK_INSTALLED: no` and `HOOKS_IN_GIT_DIR: yes`** —
   consent already given; install silently (no question) and continue:
   ```bash
   ~/.claude/skills/gstack/bin/gstack-redact install-prepush-hook
   ```
   If `HOOKS_IN_GIT_DIR: no` (husky or another committed hooks dir), do NOT
   install silently — print one line: "redact pre-push guard not installed:
   this repo uses a custom core.hooksPath; run
   `gstack-redact install-prepush-hook` manually if you want it chained."
2. **`REDACT_PREPUSH` not true AND `PREPUSH_PROMPTED: no`** — one-time
   offer (fires once EVER, machine-wide). AskUserQuestion:

   > gstack can install a per-repo git pre-push hook that blocks pushes
   > containing credentials (API keys, tokens, private keys). It's a
   > guardrail, not enforcement — `GSTACK_REDACT_PREPUSH=skip` bypasses it.
   > Install it for repos you ship from?

   Options:
   - A) Yes — install the credential guard (recommended)
   - B) No — never ask again

   If A: run `~/.claude/skills/gstack/bin/gstack-config set redact_prepush_hook true`
   then `~/.claude/skills/gstack/bin/gstack-redact install-prepush-hook`.
   If B: run `~/.claude/skills/gstack/bin/gstack-config set redact_prepush_hook false`.
   ALWAYS (after either answer, but NOT if the question itself failed to
   render — a failed AskUserQuestion must re-offer next time):
   ```bash
   touch "${GSTACK_HOME:-$HOME/.gstack}/.redact-prepush-prompted"
   ```
3. **Anything else** (declined earlier, or already installed) — continue
   without comment.

**Idempotency check:** Check if the branch is already pushed and up to date.

```bash
git fetch origin <branch-name> 2>/dev/null
LOCAL=$(git rev-parse HEAD)
REMOTE=$(git rev-parse origin/<branch-name> 2>/dev/null || echo "none")
echo "LOCAL: $LOCAL  REMOTE: $REMOTE"
[ "$LOCAL" = "$REMOTE" ] && echo "ALREADY_PUSHED" || echo "PUSH_NEEDED"
```

If `ALREADY_PUSHED`, skip the push but continue to Step 18. Otherwise push with upstream tracking:

```bash
git push -u origin <branch-name>
```

**You are NOT done.** The code is pushed but documentation sync and PR creation are mandatory final steps. Continue to Step 18.

---

**PR/MR title invariant (always applies — do not skip even if you don't open the section below):** Any PR or MR you create OR update in the next step MUST have a title that starts with `v$NEW_VERSION` (the version bumped in Step 12), in the format `v<NEW_VERSION> <type>: <summary>`. Never create or edit a PR/MR title without this prefix. Compute the correct title with the single source of truth helper: `~/.claude/skills/gstack/bin/gstack-pr-title-rewrite.sh "$NEW_VERSION" "<current title>"`. The full create/update procedure (idempotency, redaction scan, self-check) is in the section below.

{{SECTION:pr-body}}

## Step 20: Persist ship metrics

Log coverage and plan completion data so `/retro` can track trends.

Route the append through `gstack-review-log`. It resolves the project slug and
the canonical branch form itself, creates the directory, validates the JSON, and
enqueues the row for gbrain sync. It takes **no path argument** — never build a
`<branch>-reviews.jsonl` path by hand. A branch with a `/` in it turns a
hand-built path into a subdirectory write, and the row goes somewhere `/retro`
will never look.

```bash
~/.claude/skills/gstack/bin/gstack-review-log '{"skill":"ship","timestamp":"'"$(date -u +%Y-%m-%dT%H:%M:%SZ)"'","coverage_pct":COVERAGE_PCT,"plan_items_total":PLAN_TOTAL,"plan_items_done":PLAN_DONE,"verification_result":"VERIFY_RESULT","version":"VERSION","branch":"'"$(git rev-parse --abbrev-ref HEAD)"'"}'
```

Substitute from earlier steps:
- **COVERAGE_PCT**: coverage percentage from Step 7 diagram (integer, or -1 if undetermined)
- **PLAN_TOTAL**: total plan items extracted in Step 8 (0 if no plan file)
- **PLAN_DONE**: count of DONE + CHANGED items from Step 8 (0 if no plan file)
- **VERIFY_RESULT**: "pass", "fail", or "skipped" from Step 8.1
- **VERSION**: from the VERSION file

The branch name is filled in by the shell — there is no `BRANCH` placeholder to
substitute.

This step is automatic — never skip it, never ask for confirmation.

---

## Step 21: Plan-tune discoverability nudge (first-successful-ship only)

Plan-tune cathedral T15. After a successful ship, surface /plan-tune once
per machine. Single line, non-blocking, marker-gated so it never re-fires.

```bash
_NUDGE_MARKER="$HOME/.gstack/.plan-tune-nudge-shown"
_QT=$(~/.claude/skills/gstack/bin/gstack-config get question_tuning 2>/dev/null || echo "false")
if [ ! -f "$_NUDGE_MARKER" ] && [ "$_QT" = "false" ]; then
  echo ""
  echo "gstack can learn from your AskUserQuestion answers. Run /plan-tune to opt in"
  echo "— it captures which prompts you find valuable vs noisy and (with hooks installed)"
  echo "auto-decides your never-ask preferences."
  touch "$_NUDGE_MARKER"
fi
```

If the marker exists, OR question_tuning is already on, the nudge is a
no-op. The marker guarantees at-most-once per machine. To re-enable:
`rm ~/.gstack/.plan-tune-nudge-shown` before next ship.

---

## Section self-check (before you finish)

You ran a carved skill. For your situation, list every section the Section index
named as applying, and confirm you issued a Read for each one. If you executed any
of those steps from memory without reading its section, you skipped the source of
truth — STOP, Read it now, and redo that step. Deterministic version work goes
through `gstack-version-bump`; never hand-roll the VERSION/package.json write.

---

## Important Rules

- **Never skip tests.** If tests fail, stop.
- **Never skip the pre-landing review.** If checklist.md is unreadable, stop.
- **Never force push.** Use regular `git push` only.
- **Never ask for trivial confirmations** (e.g., "ready to push?", "create PR?"). DO stop for: version bumps (MINOR/MAJOR), pre-landing review findings (ASK items), and Codex structured review [P1] findings (large diffs only).
- **Always use the 4-digit version format** from the VERSION file.
- **Date format in CHANGELOG:** `YYYY-MM-DD`
- **Split commits for bisectability** — each commit = one logical change.
- **TODOS.md completion detection must be conservative.** Only mark items as completed when the diff clearly shows the work is done.
- **Use Greptile reply templates from greptile-triage.md.** Every reply includes evidence (inline diff, code references, re-rank suggestion). Never post vague replies.
- **Never push without fresh verification evidence.** If code changed after Step 5 tests, re-run before pushing.
- **Step 7 generates coverage tests.** They must pass before committing. Never commit failing tests.
- **The goal is: user says `/ship`, next thing they see is the review + PR URL + auto-synced docs.**
