What problem does it solve? Agent harnesses that span multiple AI tools (Claude, Codex) and documentation surfaces drift out of sync over time: agents lose parity, skills go unregistered, README listings go stale, and protocol references break. This Skill runs a battery of validators to detect and report that drift before it causes broken workflows. ## 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, is discoverable via the .agents/skills symlink, and is listed in README.md. - Protocol & Wiring Audits: Checks that protocol files are referenced correctly, skill invocation tokens resolve to registered skills, and agent frontmatter contains required fields like effort and skills. - Use Case: After renaming an agent or adding a new skill, run this audit to confirm Claude/Codex parity, README listings, and protocol wiring all still line up before committing. ## Quick Start Run the harness audit to check agent parity, skill registry consistency, README sync, and protocol wiring across the repository.
