What problem does it solve? Single-provider AI analysis can contain blind spots, unverified claims, or missed counterexamples. This Skill enforces a governance workflow where a primary analysis is independently reviewed by a genuinely different provider, with strict evidence, isolation, and immutability requirements before conclusions are synthesized. ## Core Features & Use Cases - Independent Peer Review: Dispatches an identical evidence-complete brief to a different provider running in a separate, read-only context. - Evidence Verification: Verifies peer claims against primary evidence, preserves disagreements, and synthesizes only supported conclusions. - Strict Blocking Rules: Returns REVIEW-BLOCKED when transport, identity, isolation, coverage, or worktree integrity cannot be proven. - Use Case: Before merging a high-stakes governance change, run the primary analysis, then have an independent provider review the same frozen brief and evidence digests, and synthesize only mutually supported findings. ## Quick Start Run an independent peer review of my current analysis using the codex-collab workflow and synthesize the verified findings.
