What agent-rules does

This skill creates machine-oriented documentation following the AGENTS.md convention. It inspects the repository, identifies languages and build tools across Go, PHP, TypeScript, or Python, and extracts CI quality gates. It can also link CLAUDE.md and GEMINI.md automatically.

Under the hood, several bash utilities inspect scopes, score files, and verify that documented shell commands execute properly. Scripts must be invoked via their full ${CLAUDE_SKILL_DIR} path. Relative paths trigger security permission prompts on every call.

Execution requires bash 4.3+, jq 1.7+, and git 2.0+. The root AGENTS.md must stay under 150 lines, or CI harness validation checks fail.

What it helps with

scaffold AGENTS.md files for new or existing codebases
verify documented commands and paths against actual code
audit and grade existing AI agent documentation
create symlinks for CLAUDE.md and GEMINI.md automatically

Example prompts for the agent

Generate an AGENTS.md file for this project
Verify that all commands in AGENTS.md are working
Score the quality of existing agent rule files
