# 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, classify, and **escalation detection** 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:

```bash
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)`

Before replying to any comment, run the **Escalation Detection** algorithm from greptile-triage.md to determine whether to use Tier 1 (friendly) or Tier 2 (firm) reply templates.

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 A (fix), reply using the **Fix reply template** from greptile-triage.md (include inline diff + explanation). If the user chooses C (false positive), reply using the **False Positive reply template** (include evidence + suggested re-rank), save to both per-project and global greptile-history.

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, reply using the **False Positive reply template** from greptile-triage.md (include evidence + suggested re-rank), save to both per-project and global greptile-history.

3. **VALID BUT ALREADY FIXED comments:** Reply using the **Already Fixed reply template** from greptile-triage.md — no AskUserQuestion needed:
   - Include what was done and the fixing commit SHA
   - Save to both per-project and global greptile-history

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

---

## Step 5.5: TODOS cross-reference

Read `TODOS.md` in the repository root (if it exists). Cross-reference the PR against open TODOs:

- **Does this PR close any open TODOs?** If yes, note which items in your output: "This PR addresses TODO: <title>"
- **Does this PR create work that should become a TODO?** If yes, flag it as an informational finding.
- **Are there related TODOs that provide context for this review?** If yes, reference them when discussing related findings.

If TODOS.md doesn't exist, skip this step silently.

---

## 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.
- **Use Greptile reply templates from greptile-triage.md.** Every reply includes evidence. Never post vague replies.
