What problem does it solve? Repositories often lack a concise, agent-readable onboarding document, so AI coding agents waste context rediscovering build commands, conventions, and hard rules on every session. This Skill inspects the repo and writes a tight AGENTS.md that a fresh agent can read once and stay unblocked. ## Core Features & Use Cases - Repo inspection and drafting: Reads the manifest, README, lint/test/CI configs, directory layout, and git history to extract only project-specific, checkable facts. - Create and update paths: Writes a new AGENTS.md when none exists, or performs surgical, git-diff-driven updates that preserve still-valid content when one does. - Repo-level and directory-level scopes: Produces a root onboarding guide or a focused per-directory guide (e.g. src/api/AGENTS.md) with local conventions inferred from sibling files. - Use Case: After adding a new test framework and renaming npm scripts, run the update flow to refresh AGENTS.md so it cites the current commands instead of stale ones. ## Quick Start Ask the agent to create an AGENTS.md onboarding document for this repository.
