AGENTS.md Generator (Root + Nested, Portable)

Goal

Maintain small, high-signal AGENTS.md files:

• Root AGENTS.md — purpose of repository, navigation, universal toolchain, canonical commands, links to docs and skills.
• Nested AGENTS.md — module/package purpose, local commands, module references.

Use progressive disclosure : keep AGENTS.md concise; push details to docs or skills.

Skill location (agent-specific)

• Do NOT assume.agents/ or any fixed directory exists.
• Skills may live:
  • inside the repository (embedded),
  • or in an external/global skill library (external).
• If referencing local skills, first detect an existing skill root already used by the project.
• If no local skill directory exists — reference skills by name only (external).
• Never create hidden agent directories just to store skills.

When to run

Run this skill when:

• AGENTS.md is missing, bloated, contradictory, or outdated.
• A new package/service/module appears.
• Repository structure changes (monorepo growth or split).
• Teams want consistent agent context across diverse stacks.

Workflow (Deterministic)

1. Discover repository shape

• Identify repository root (git root if available).
• Detect language/tool markers:
  • package.json, pnpm-workspace.yaml
  • go.mod, go.work
  • pyproject.toml
  • Cargo.toml
  • pubspec.yaml
  • pom.xml, build.gradle
• Locate docs/, , existing .

2. Detect module boundaries

Create nested AGENTS.md if directory:

• Contains independent build/package manifest
• OR represents deployable/service unit (apps/, services/, packages/)
• AND differs in stack/toolchain from parent scope

3. Generate/Update Root AGENTS.md

Constraints:

• Ideal size: ≤ 60 lines
• Must include:
  • One-sentence repository purpose
  • Primary toolchain/package manager
  • Canonical commands (if non-standard)
  • Links to docs
  • Instruction to read nested AGENTS.md when inside modules
  • Optional skill references (adaptive: local or external)

4. Generate/Update Nested AGENTS.md

Constraints:

• Ideal size: ≤ 40 lines
• Must include:
  • One-sentence module purpose
  • Module-specific commands
  • Local documentation references
  • Optional skill references (adaptive)

5. Progressive Disclosure Rules

• Do not embed style guides, CI policies, or architecture details.
• Prefer links to:
  • docs/STYLE_GUIDE.md
  • docs/ARCHITECTURE.md
  • external or local skills
• Avoid “always/never” rules unless critical for correctness/security.

6. Safety / Correctness Gates

• Never invent commands.
• Infer commands from:
  • package scripts
  • Makefile
  • CI configuration
  • README
• If uncertain → write: “Known commands: see ”
• Preserve critical warnings (security, secrets, deployment).

Output Contract

Create or update only:

• <repo_root>/AGENTS.md
• <module_dir>/AGENTS.md

Do not create agent configuration folders.

Skill Referencing Strategy

When adding skill references inside AGENTS.md:

1. If local skill directory detected

   See: <detected-skill-root>/<skill-name>/SKILL.md
   

2. If no local directory exists

   Skill: agents-md-generator (external)
   

Never assume filesystem paths.
