What problem does it solve? Reviewing multi-file changes and pull requests by reading files inline wastes tokens and misses cross-module impact. This Skill enforces a graph-first review chain that maps blast radius before reading code, so reviewers only open confirmed-relevant files and report verified findings. ## Core Features & Use Cases - Graph-first review chain: Runs code-review-graph (detect_changes, impact radius, review context), then gbrain symbol resolution, then scoped file reads — never whole-repo scans. - Delta and PR modes: Single-pass review for local diffs; five-lens parallel fan-out (guidelines, shallow bugs, git history, prior PRs, in-file guidance) for full PR reviews. - Confidence-gated reporting: Every finding is scored 0-100; only issues at 80 or above reach the report, with Critical/Important severity tiers and file:line citations. - Use Case: Before merging a branch that touches a shared API contract, run the PR mode to map the blast radius, fan out lens workers across orchestration backends, and receive a merged, deduplicated verdict of Yes, No, or With fixes. ## Quick Start Ask the agent to review your uncommitted changes or a specific pull request using the code-review skill, for example: review my uncommitted delta for bugs before I commit.
