What problem does it solve? AI coding agents forget rules mid-session, config files sprawl and contradict each other, and stale doctrine drifts from the actual codebase. This Skill installs a structured collaboration harness (AGENTS.md, CLAUDE.md, .agents/ directory) that keeps agents and humans aligned without overwriting existing project memory. ## Core Features & Use Cases - Bootstrap or audit a harness: Inventory an existing repo, infer the right size (S/M/L) from signals like agent count and AGENTS.md line count, and generate only the missing files from templates. - Three additive sizes plus L+ profile: S ships the minimal contract and learning loop; M adds a router, status log, and PR risk-rail template; L adds patterns, rules, ADRs, a meta-validator, and CI rail-guard; L+ is an opt-in ADR-gated autonomy profile with hooks and a bounded /loop workflow. - Drift detection and learning loop: Ships a meta-validator script, a fleet audit script, and /learn and /retro workflows that turn each friction into one actionable edit. - Use Case: Point it at a repo where Claude Code keeps ignoring conventions; it detects the existing .cursorrules and .github folder, proposes size M, and generates AGENTS.md, ROUTER.md, and a PR template without touching existing files. ## Quick Start Audit my repository against the AI harness blueprint and tell me which files are missing for size M.
