What problem does it solve? Code reviews often miss regressions that live outside the diff — broken dependents, removed sanitizers, stale baselines, and untested behavior changes. This Skill performs evidence-backed reviews of PRs, branches, commit ranges, or local changes by combining the raw git diff with GitNexus dependency-graph, impact, and taint analysis. ## Core Features & Use Cases - Flexible target resolution: Accepts a PR URL or number, a branch/ref, a base...head or A..B range, or local staged/unstaged/untracked changes, resolving each to exact base and head SHAs. - Graph-backed impact analysis: Runs detect_changes, impact, context, and PDG-based taint passes to find broken dependents, source-to-sink flows, and missing test coverage. - Expert lens and swarm lanes: Dispatches domain-specific reviewer lenses plus six read-only CI personas (correctness, security, blast radius, coverage, adversarial, critic) for multi-domain changes. - Use Case: Ask for a review of PR #42; the Skill pins the merge-base, diffs it against the head in a temporary worktree, traces every behaviorally changed symbol's dependents, and returns a severity-ordered findings list with an APPROVE or REQUEST CHANGES verdict. ## Quick Start Review the changes in PR #42 of this repository and tell me whether it is safe to merge.
