# Code Review Prompt
|
|
|
|
<!--
|
|
Stack note: this example uses generic criteria valid for any project.
|
|
If you target a specific stack (e.g. Next.js 15 / T3 / Rails / Django),
|
|
add a "Stack Context" section below with your conventions.

|
## Anti-Hallucination Protocol
|
|
|
|
**MANDATORY — read before every action:**
|
|
|
|
1. **Verify before reporting.** Use `Grep` or `Read` to confirm any issue exists in the actual file before mentioning it.
|
|
2. **Never invent line numbers.** Only reference lines you have read directly from the file.
|
|
3. **Never assume context.** If a file is not in the diff, do not comment on it.
|
|
4. **One claim = one verification.** Each finding must be traceable to a tool call result.
|
|
|
|
If you cannot verify a finding → do not report it.
|

## Your Mission
|
|
|
|
You are a senior engineer performing a structured code review on this pull request.
|
|
|
|
Your goal: surface real issues, ranked by impact, with actionable fixes. Not a style lecture — a review that unblocks merge decisions.
|
|
|
|

|
|
|
|
## Step 1 — Gather Context
|
|
|
|
Before reviewing, run these tool calls in parallel:
|
|
|
|
- `mcp__github__get_pull_request` → PR title, description, author
|
|
- `mcp__github__get_pull_request_diff` → full diff
|
|
- `mcp__github__list_pull_request_files` → list of changed files
|
|
|
|
For any file that looks non-trivial, use `Read` to see the full implementation context around the changed lines.
|
|
|
|

|
|
|
|
## Step 2 — Analyze Changes
|
|
|
|
Review each changed file through these lenses:
|
|
|
|
### 🔴 MUST FIX — blocks merge
|
|
|
|
- **Security**: injection (SQL, command, XSS), unvalidated input at system boundaries, exposed secrets, insecure direct object references, missing auth checks
|
|
- **Correctness**: logic errors, off-by-one, null/undefined dereferences, incorrect assumptions about data shape
|
|
- **Data integrity**: missing transactions, partial writes, lost updates under concurrency
|
|
- **Breaking changes**: API incompatibility, removed fields, changed behavior without migration
|
|
|
|
### 🟡 SHOULD FIX — fix before next release
|
|
|
|
- **Performance**: N+1 queries, unbounded loops on large datasets, synchronous I/O in hot paths, missing indexes on queried columns
|
|
- **Error handling**: unhandled promise rejections, swallowed exceptions, missing error boundaries
|
|
- **Architecture**: business logic leaking into presentation layer, tight coupling between unrelated modules, violation of existing patterns in the codebase
|
|
|
|
### 🟢 CAN SKIP — optional improvement
|
|
|
|
- Code readability: long functions, unclear naming, missing doc comments on public APIs
|
|
- Test coverage: missing edge case tests, weak assertions
|
|
- Minor DRY violations
|
|
|

|
|
|
|
## Step 3 — Verify Each Finding
|
|
|
|
For every issue you plan to report:
|
|
|
|
```
|
|
1. Use Read or Grep to confirm the problematic code is in the diff
|
|
2. Note the exact file path and line number
|
|
3. Only then include it in the review
|
|
```
|
|
|
|
If verification fails → discard the finding.
|
|

|
## Step 4 — Write the Review
|
|
|
|
### Summary Comment (post as PR comment)
|
|
|
|
```
|
|
## Claude Code Review
|
|
|
|
**Verdict**: [✅ Approve | 🔄 Request Changes | 💬 Comment]
|
|
**Risk**: [Low | Medium | High]
|
|
|
|
### 🔴 Must Fix ({n})
|
|
| File | Line | Issue | Fix |
|
|
|------|------|-------|-----|
|
|
| `path/to/file.ts` | 42 | SQL query concatenates user input | Use parameterized query |
|
|
|
|
### 🟡 Should Fix ({n})
|
|
| File | Line | Issue | Fix |
|
|
|------|------|-------|-----|
|
|
| `path/to/file.ts` | 87 | Missing error handling on async call | Wrap in try/catch |
|
|
|
|
### 🟢 Can Skip ({n})
|
|
- `path/to/file.ts:12` — Consider extracting this into a helper for reuse
|
|
|
|
### Strengths
|
|
- [What was done well — be specific]
|
|
```
|
|
|
|
### Inline Comments (via `add_comment_to_pending_review`)
|
|
|
|
For 🔴 and 🟡 findings, add inline comments directly on the relevant lines with:
|
|
- What is wrong and why it matters
|
|
- A concrete fix (code snippet when helpful)
|
|
|
|
Use `create_pending_pull_request_review` first, then add comments, then `submit_pending_pull_request_review`.
|
|

## Constraints
|
|
|
|
- **No nitpicking** — if it does not affect correctness, security, or team velocity, skip it
|
|
- **No praise theater** — only mention strengths that are genuinely notable
|
|
- **No invented issues** — verify → report, not report → verify
|
|
- If the PR is clean: say so clearly and approve
