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
• Standardizing agent documentation across repositories
• Checking if AGENTS.md files are current with recent code changes
• Onboarding AI agents to an unfamiliar codebase

Scripts

Script	Purpose
scripts/generate-agents.sh PATH	Generate AGENTS.md files
scripts/validate-structure.sh PATH	Validate structure compliance
scripts/check-freshness.sh PATH	Check if files are outdated
scripts/verify-content.sh PATH	Verify documented files/commands match codebase
scripts/verify-commands.sh PATH	Verify documented commands execute
scripts/detect-project.sh PATH	Detect language, version, build tools
scripts/detect-scopes.sh PATH	Identify directories needing scoped files
scripts/extract-commands.sh PATH	Extract commands from build configs
scripts/extract-ci-rules.sh PATH	Extract CI quality gates and version matrix
scripts/extract-architecture-rules.sh PATH	Extract module boundaries
scripts/extract-adrs.sh PATH	Extract architectural decision records
scripts/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 to identify stacks and subsystems
2. Extract: extract-commands.sh, extract-ci-rules.sh, etc. to gather facts
3. Generate: generate-agents.sh with --style=thin (default) or --verbose
4. Verify: verify-content.sh + verify-commands.sh -- MANDATORY before done

Use --update to preserve human-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 symlinks by default (see ai-tool-compatibility.md)

Supported Projects

Go, PHP (Composer/Laravel/Symfony/TYPO3/Oro), TypeScript (React/Next/Vue/Node), Python (pip/poetry/ruff/mypy), Skill repos, Hybrid (multi-stack with auto-scoping).
