Update Check (run first)

_UPD=$(~/.claude/skills/gstack/bin/gstack-update-check 2>/dev/null || .claude/skills/gstack/bin/gstack-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD"

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/gstack/gstack-upgrade/SKILL.md and follow the "Inline upgrade flow" (AskUserQuestion → upgrade if yes, touch ~/.gstack/last-update-check if no). If JUST_UPGRADED <from> <to>: tell user "Running gstack v{to} (just updated!)" and continue.

Pre-Landing PR Review

You are running the /review workflow. Analyze the current branch's diff against main for structural issues that tests don't catch.

---

Step 1: Check branch

1. Run git branch --show-current to get the current branch.
2. If on main, output: "Nothing to review — you're on main or have no changes against main." and stop.
3. Run git fetch origin main --quiet && git diff origin/main --stat to check if there's a diff. If no diff, output the same message and stop.

---

Step 2: Read the checklist

Read .claude/skills/review/checklist.md.

If the file cannot be read, STOP and report the error. Do not proceed without the checklist.

---

Step 2.5: Check for Greptile review comments

Read .claude/skills/review/greptile-triage.md and follow the fetch, filter, and classify steps.

If no PR exists, gh fails, API returns an error, or there are zero Greptile comments: Skip this step silently. Greptile integration is additive — the review works without it.

If Greptile comments are found: Store the classifications (VALID & ACTIONABLE, VALID BUT ALREADY FIXED, FALSE POSITIVE, SUPPRESSED) — you will need them in Step 5.

---

Step 3: Get the diff

Fetch the latest main to avoid false positives from a stale local main:

git fetch origin main --quiet

Run git diff origin/main to get the full diff. This includes both committed and uncommitted changes against the latest main.

---

Step 4: Two-pass review

Apply the checklist against the diff in two passes:

1. Pass 1 (CRITICAL): SQL & Data Safety, LLM Output Trust Boundary
2. Pass 2 (INFORMATIONAL): Conditional Side Effects, Magic Numbers & String Coupling, Dead Code & Consistency, LLM Prompt Issues, Test Gaps, View/Frontend

Follow the output format specified in the checklist. Respect the suppressions — do NOT flag items listed in the "DO NOT flag" section.

---

Step 5: Output findings

Always output ALL findings — both critical and informational. The user must see every issue.

• If CRITICAL issues found: output all findings, then for EACH critical issue use a separate AskUserQuestion with the problem, your recommended fix, and options (A: Fix it now, B: Acknowledge, C: False positive — skip). After all critical questions are answered, output a summary of what the user chose for each issue. If the user chose A (fix) on any issue, apply the recommended fixes. If only B/C were chosen, no action needed.
• If only non-critical issues found: output findings. No further action needed.
• If no issues found: output Pre-Landing Review: No issues found.

Greptile comment resolution

After outputting your own findings, if Greptile comments were classified in Step 2.5:

Include a Greptile summary in your output header: + N Greptile comments (X valid, Y fixed, Z FP)

1. VALID & ACTIONABLE comments: These are already included in your CRITICAL findings — they follow the same AskUserQuestion flow (A: Fix it now, B: Acknowledge, C: False positive). If the user chooses C (false positive), post a reply using the appropriate API from the triage doc and save the pattern to both per-project and global greptile-history (see greptile-triage.md for write details).

2. FALSE POSITIVE comments: Present each one via AskUserQuestion:

   • Show the Greptile comment: file:line (or [top-level]) + body summary + permalink URL
   • Explain concisely why it's a false positive
   • Options:
     • A) Reply to Greptile explaining why this is incorrect (recommended if clearly wrong)
     • B) Fix it anyway (if low-effort and harmless)
     • C) Ignore — don't reply, don't fix

   If the user chooses A, post a reply using the appropriate API from the triage doc and save the pattern to both per-project and global greptile-history (see greptile-triage.md for write details).

3. VALID BUT ALREADY FIXED comments: Reply acknowledging the catch — no AskUserQuestion needed:

   • Post reply: "Good catch — already fixed in <commit-sha>."
   • Save to both per-project and global greptile-history (see greptile-triage.md for write details)

4. SUPPRESSED comments: Skip silently — these are known false positives from previous triage.

Important Rules

• Read the FULL diff before commenting. Do not flag issues already addressed in the diff.
• Read-only by default. Only modify files if the user explicitly chooses "Fix it now" on a critical issue. Never commit, push, or create PRs.
• Be terse. One line problem, one line fix. No preamble.
• Only flag real problems. Skip anything that's fine.
