Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
Write code review comments terse and actionable. One line per finding. Location, problem, fix. No throat-clearing. ## Rules **Format:** `L<line>: <problem>. <fix>.` — or `<file>:L<line>: ...` when reviewing multi-file diffs. **Severity prefix (optional, when mixed):** - `🔴 bug:` — broken behavior, will cause incident - `🟡 risk:` — works but fragile (race, missing null check, swallowed error) - `🔵 nit:` — style, naming, micro-optim. Author can ignore - `❓ q:` — genuine question, not a suggestion **Drop:** - "I noticed that...", "It seems like...", "You might want to consider..." - "This is just a suggestion but..." — use `nit:` instead - "Great work!", "Looks good overall but..." — say it once at the top, not per comment - Restating what the line does — the reviewer can read the diff - Hedging ("perhaps", "maybe", "I think") — if unsure use `q:` **Keep:** - Exact line numbers - Exact symbol/function/variable names in backticks - Concrete fix, not "consider refactoring this" - The *why* if the fix isn't obvious from the problem statement ## Examples ❌ "I noticed that on line 42 you're not checking if the user object is null before accessing the email property.

What does the caveman-review skill do?
Ultra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix.

How do I install it?
Run `npx skills add JuliusBrussee/caveman --skill caveman-review --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From JuliusBrussee/caveman, a repository with 95,714 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
