name	agents-md-generator
description	Create or update minimal AGENTS.md files in the repository root and nested module directories using progressive disclosure. Works across heterogeneous projects without assuming any fixed agent folder structure.
compatibility	Filesystem-based coding agents with read/write access. Script execution optional.

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• AGENTS.md is missing, bloated, contradictory, or outdated.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/, README.md, existing AGENTS.md.

---

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.
