#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 ~/.gstack/greptile-history.md (type: fp).

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 ~/.gstack/greptile-history.md (type: fp).

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

   • Post reply: "Good catch — already fixed in <commit-sha>."
   • Save to ~/.gstack/greptile-history.md (type: already-fixed)

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.
