10x-agents-md

Invoke the skill with no arguments to write AGENTS.md at the repo root. It reads your README, package manifest, lint and test configs, CI workflows, and git history, then drafts a concise Repository Guidelines document ordered with critical rules first.

Run the skill against the existing file and it enters update mode. It finds the file's last-touched commit, diffs repo state since then, classifies each line as keep, update, remove, or missing, and asks for confirmation before applying surgical edits.

Yes, pass a directory path as the argument and the skill switches to directory-level scope. It inspects sibling files to infer local conventions and writes a shorter 120-250 word guide focused on that directory's patterns rather than repo-wide onboarding.

Yes, the skill is host-agnostic. It self-discovers whichever interactive-question and subagent tools the host exposes, such as ask_question in Cursor or request_user_input in Codex, and falls back to plain chat prompts if none exist.

The output is capped at 200-400 words, contains no multi-line code snippets, and only includes rules traceable to actual repo files. It will not invent project facts, so repos without a README or manifest require a manual project description first.
