caveman-review

One-line PR comments. Location, problem, fix. No throat-clearing.

What it does

Generates code review comments in L<line>: <severity> <problem>. <fix>. format. One line per finding. Severity emoji: 🔴 bug, 🟡 risk, 🔵 nit, ❓ question. Drops "I noticed that...", hedging, and restating what the diff already shows. Keeps exact line numbers, backticked symbols, and concrete fixes.

Auto-clarity: drops terse mode for CVE-class security findings, architectural disagreements, and onboarding contexts where the author needs the *why*. Resumes terse for the rest.

Output only — does not approve, request changes, or run linters.

How to invoke

/caveman-review

Also triggers on "review this PR", "code review", "review the diff".

Example output

L42: 🔴 bug: user can be null after .find(). Add guard before .email.

L23: 🟡 risk: no retry on 429. Wrap in withBackoff(3).
L107: ❓ q: why drop the cache here? Reads on next request will miss.
