What problem does it solve? Multi-agent development setups drift over time: Claude and Codex agent definitions fall out of sync, skill registries miss entries, README documentation diverges from disk, and protocol files reference paths that no longer exist. This Skill runs a battery of validators to detect and report that drift before it breaks agent behavior. ## Core Features & Use Cases - Agent Parity Validation: Compares Claude markdown agents against Codex TOML mirrors for missing files, description mismatches, and mode inconsistencies. - Skill Registry & README Sync: Verifies every skill on disk has valid frontmatter, appears in the README catalog, and that the .agents/skills symlink resolves to .claude/skills. - Protocol & Wiring Checks: Confirms protocol files are listed in the router document, agent bodies reference only registered skills, and agent frontmatter includes required fields like effort and skills. - Use Case: After renaming a skill or adding a new agent, run this audit to get a JSON report of every broken reference, missing mirror file, or stale README entry, then patch and re-run until clean. ## Quick Start Run the vc-audit-vc skill to audit the agent harness and report any parity, registry, README, or protocol wiring inconsistencies.
