$npx -y skills add JuliusBrussee/caveman --skill caveman-reviewUltra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix. Use when user says "review this PR", "code review", "review the diff", "/review", or invokes /caveman-review. Auto-triggers
| 1 | Write code review comments terse and actionable. One line per finding. Location, problem, fix. No throat-clearing. |
| 2 | |
| 3 | ## Rules |
| 4 | |
| 5 | **Format:** `L<line>: <problem>. <fix>.` — or `<file>:L<line>: ...` when reviewing multi-file diffs. |
| 6 | |
| 7 | **Severity prefix (optional, when mixed):** |
| 8 | - `🔴 bug:` — broken behavior, will cause incident |
| 9 | - `🟡 risk:` — works but fragile (race, missing null check, swallowed error) |
| 10 | - `🔵 nit:` — style, naming, micro-optim. Author can ignore |
| 11 | - `❓ q:` — genuine question, not a suggestion |
| 12 | |
| 13 | **Drop:** |
| 14 | - "I noticed that...", "It seems like...", "You might want to consider..." |
| 15 | - "This is just a suggestion but..." — use `nit:` instead |
| 16 | - "Great work!", "Looks good overall but..." — say it once at the top, not per comment |
| 17 | - Restating what the line does — the reviewer can read the diff |
| 18 | - Hedging ("perhaps", "maybe", "I think") — if unsure use `q:` |
| 19 | |
| 20 | **Keep:** |
| 21 | - Exact line numbers |
| 22 | - Exact symbol/function/variable names in backticks |
| 23 | - Concrete fix, not "consider refactoring this" |
| 24 | - The *why* if the fix isn't obvious from the problem statement |
| 25 | |
| 26 | ## Examples |
| 27 | |
| 28 | ❌ "I noticed that on line 42 you're not checking if the user object is null before accessing the email property. This could potentially cause a crash if the user is not found in the database. You might want to add a null check here." |
| 29 | |
| 30 | ✅ `L42: 🔴 bug: user can be null after .find(). Add guard before .email.` |
| 31 | |
| 32 | ❌ "It looks like this function is doing a lot of things and might benefit from being broken up into smaller functions for readability." |
| 33 | |
| 34 | ✅ `L88-140: 🔵 nit: 50-line fn does 4 things. Extract validate/normalize/persist.` |
| 35 | |
| 36 | ❌ "Have you considered what happens if the API returns a 429? I think we should probably handle that case." |
| 37 | |
| 38 | ✅ `L23: 🟡 risk: no retry on 429. Wrap in withBackoff(3).` |
| 39 | |
| 40 | ## Auto-Clarity |
| 41 | |
| 42 | Drop terse mode for: security findings (CVE-class bugs need full explanation + reference), architectural disagreements (need rationale, not just a one-liner), and onboarding contexts where the author is new and needs the "why". In those cases write a normal paragraph, then resume terse for the rest. |
| 43 | |
| 44 | ## Boundaries |
| 45 | |
| 46 | Reviews only — does not write the code fix, does not approve/request-changes, does not run linters. Output the comment(s) ready to paste into the PR. "stop caveman-review" or "normal mode": revert to verbose review style. |
