What problem does it solve? Reviewing large diffs, branches, or pull requests by hand is slow and inconsistent, and single-pass reviews miss issues across security, correctness, testing, and spec compliance. This Skill runs a structured multi-persona code review that produces a deduplicated, severity-ranked report with verified/unverified confidence labels. ## Core Features & Use Cases - Parallel persona review: Dispatches up to 12 specialized reviewer personas (correctness, security, spec-compliance, adversarial, maintainability, testing, and more) against a diff, with always-on and conditionally-triggered roles. - Two review modes: A fast default mode that batches Sonnet-tier personas into one mega-spawn, and a thorough mode that fully isolates every persona for maximum coverage. - Stage-2 synthesis and reporting: An Opus advisor pass deduplicates and reranks findings, then emits a Spec compliance section plus a severity-grouped findings table with confidence and routing labels. - Use Case: Run a thorough review of a pre-release feature branch to catch security regressions, spec mismatches, and untested edge cases before merging. ## Quick Start Ask the AI to run code-crit on the current branch diff, optionally adding the word thorough for a fully isolated deep review.
