AGENTS.md Generator Skill

Generate and maintain AGENTS.md files following the agents.md convention. AGENTS.md is FOR AGENTS, not humans.

When to Use

• Creating or updating AGENTS.md for new/existing projects
• Scaffolding a new repository — ship AGENTS.md with the initial commits; retrofitting later needs full re-verification
• Standardizing agent documentation across repositories
• Checking AGENTS.md freshness after code changes
• Onboarding AI agents to an unfamiliar codebase

Scripts

Call every script by its full path: bash ${CLAUDE_SKILL_DIR}/scripts/<name> PATH. Calling one relative to the working directory is not covered by the frontmatter rule and raises a permission prompt per call.

Script	Purpose
generate-agents.sh PATH	Generate AGENTS.md files
validate-structure.sh PATH	Validate structure compliance
check-freshness.sh PATH	Check if files are outdated
verify-content.sh PATH	Verify documented files/commands match codebase
verify-commands.sh PATH	Verify documented commands execute
score-agents.sh PATH	Grade AGENTS.md quality, worst-first
detect-project.sh PATH	Detect language, version, build tools
detect-scopes.sh PATH	Identify directories needing scoped files
extract-commands.sh PATH	Extract commands from build configs
extract-ci-rules.sh PATH	Extract CI quality gates and version matrix
extract-architecture-rules.sh PATH	Extract module boundaries
extract-adrs.sh PATH	Extract architectural decision records
extract-github-rulesets.sh PATH	Extract GitHub rulesets and merge rules

See references/scripts-guide.md for full options.

Workflow

1. Detect: detect-project.sh + detect-scopes.sh — stacks and subsystems
2. Extract: extract-commands.sh, extract-ci-rules.sh — gather facts
3. Generate: generate-agents.sh --style=thin (default) or --verbose
4. Verify: verify-content.sh + verify-commands.sh -- MANDATORY before done

--update preserves curated content outside <!-- GENERATED --> markers.

Core Principles

• Structured over Prose -- tables parse faster than paragraphs
• Never Fabricate -- only document what exists; verify every command and path
• Pointer Principle -- point to files, don't duplicate content
• Auto Symlinks -- CLAUDE.md/GEMINI.md by default (ai-tool-compatibility.md)
