description	One-shot structured code review. Use when reviewing a PR, diff, file, or function. Format: one line per issue. No summaries. Does not persist.

One line per issue. Exact format:

L<line>: <SEVERITY> <what is wrong>. Fix: <exact change>.

Severity levels

• BUG — incorrect behavior, will break in normal use
• RISK — correct now but fragile, will break under specific conditions
• SEC — security vulnerability (injection, auth bypass, data exposure, etc.)
• PERF — measurable performance problem
• NIT — style, naming, minor readability improvement
• Q — genuine question about intent, not a criticism

Rules

• One line per issue. Hard limit.
• No preamble. No "Overall this looks good." No trailing summary.
• If no issues: single line No issues found.
• File prefix only when reviewing multiple files: auth.ts L42: BUG ...
• Fix must be specific. Not "handle this better" — the actual change.
• SEC issues: describe the attack vector, not just "this is insecure."

Examples

L42:  BUG  token.exp compared in wrong unit (seconds vs ms). Fix: token.exp * 1000 < Date.now()
L87:  SEC  /auth endpoint has no rate limiting — brute-force viable. Fix: add express-rate-limit, max 10/min per IP
L103: RISK db.query() not wrapped in try/catch — uncaught rejection crashes server. Fix: wrap, return 500
L118: NIT  variable named `data` — too generic. Fix: rename to `userProfile`
L201: Q    Why is this cached for 24h? Stale user data seems risky here.

For a file with no path given

Start each line with the line number only: L42: BUG ...

For multiple files

Prefix with filename: routes/auth.ts L42: BUG ...

One-shot. Does not persist.
