What problem does it solve? AI coding agents landing in an unfamiliar repository lack a concise, project-specific onboarding guide, leading to wrong conventions, stale commands, and repeated mistakes. This Skill inspects the repository and writes a tight AGENTS.md so future agent sessions start unblocked. ## Core Features & Use Cases - Create and update flows: Generates a new AGENTS.md from repo discovery, or surgically updates an existing one by diffing repository state against the file's last-touched commit. - Repo-level and directory-level scopes: Produces a high-level root onboarding guide or a focused per-directory guide (e.g. src/components/AGENTS.md) based on where it is invoked. - Quality-guarded output: Enforces a 200-400 word budget, @-references instead of code snippets, checkable rules only, and critical-rules-first ordering. - Use Case: After adding new npm scripts and a CI workflow to your project, invoke the skill to refresh AGENTS.md so it reflects renamed scripts, new lint rules, and current commit conventions without clobbering hand-edited content. ## Quick Start Ask the agent to create an AGENTS.md onboarding document for this repository using the 10x-agents-md skill.
