What problem does it solve? Pull request feedback often drowns in hedging, filler phrases, and restated code, making reviewers slow to write and authors slow to act. This Skill compresses every review finding into a single actionable line so feedback stays dense and readable. ## Core Features & Use Cases - One-line findings: Each comment follows the format L<line>: <problem>. <fix>. with exact line numbers and symbol names in backticks. - Severity prefixes: Optional emoji tags distinguish bugs (🔴), risks (🟡), nits (🔵), and genuine questions (❓) when severity is mixed. - Auto-clarity fallback: Security findings, architectural disagreements, and onboarding contexts automatically revert to full explanatory paragraphs. - Use Case: A reviewer pastes a multi-file diff and receives paste-ready comments like auth.py:L42: 🔴 bug: user can be null after .find(). Add guard before .email. ## Quick Start Ask the AI to review this pull request diff using caveman-review and output one-line comments ready to paste into the PR.
