What problem does it solve? PR review feedback is often buried under hedging, filler phrases, and restated diff content, making comments slow to write and slow to read. This Skill compresses every finding into a single actionable line so reviewers communicate faster without losing signal. ## Core Features & Use Cases - Terse comment format: Each finding follows L<line>: <severity> <problem>. <fix>. with exact line numbers and backticked symbol names. - Severity tagging: Uses 🔴 bug, 🟡 risk, 🔵 nit, and ❓ question prefixes to prioritize findings at a glance. - Auto-clarity mode: Automatically expands to full paragraphs for CVE-class security findings, architectural disagreements, and onboarding contexts, then resumes terse output. - Use Case: Paste a pull request diff and ask for a review; receive paste-ready one-line comments like L42: 🔴 bug: user can be null after .find(). Add guard before .email. ## Quick Start Ask the assistant to review this PR diff using caveman-review and output one-line comments with severity tags.
