Writes and trims AGENTS.md at the repo root and in nested modules. Useful when agent instructions have grown bloated or contradict each other.

## What it does

The skill walks the agent through discovery first: find the git root, then look for toolchain markers such as `package.json`, `go.mod`, `pyproject.toml`, `Cargo.toml`, `pom.xml`. From there it decides whether a nested `AGENTS.md` is warranted at all. A directory qualifies only if it has its own build manifest or stands as a deployable unit, and only if it adds commands, docs or deployment notes the parent scope lacks. A file that just repeats the root rules does not get created.

Output is two shapes: a root file capped at 60 lines and a module file at 40. Each holds a one-sentence purpose, the package manager, non-standard commands and links to docs. Style guides and CI policy stay out — the skill points at existing documentation instead of copying it.

Commands are never invented. They come from package scripts, a `Makefile`, CI config or the README. When nothing verifies a command, the file gets a pointer to an existing source instead. The skill also carries over security, secrets and deployment warnings from an existing `AGENTS.md`, and checks that no `<...>` placeholders survive. It will not spin up hidden agent directories; if there is no local skill folder, skills are referenced by name. All it needs is an agent with read and write access — script execution is optional.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MADTeacher/mad-agents-skills --skill agents-md-generator -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/agents-md-generator/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/agents-md-generator/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MADTeacher/mad-agents-skills --skill agents-md-generator -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/agents-md-generator/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MADTeacher/mad-agents-skills --skill agents-md-generator -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/agents-md-generator/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MADTeacher/mad-agents-skills agents-md-generator
```

2. **Manually: put the files in place**
- File: `.github/skills/agents-md-generator/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MADTeacher/mad-agents-skills --skill agents-md-generator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MADTeacher/mad-agents-skills --path agents-md-generator
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/agents-md-generator/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MADTeacher/mad-agents-skills --skill agents-md-generator -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/MADTeacher/mad-agents-skills/tree/HEAD/agents-md-generator/SKILL.md

## When to use it
- write a root AGENTS.md from scratch for a new repo
- split a bloated AGENTS.md into root and module files
- strip contradictory or outdated instructions from agent context
- add an AGENTS.md for a new package or service in a monorepo
- move style guides and CI policy into docs, leaving links behind

## Example prompts
- Generate an AGENTS.md for the repository root
- Trim AGENTS.md and replace long sections with links to docs
- Add a nested AGENTS.md for the apps/api package

# 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, use only an existing skill root already used by
  the project or an existing project path already mentioned by repo docs.
- If no local skill directory exists — **reference skills by name only (external)**.
- **Never create hidden agent directories** just to store skills.

---

## Resource Routing

Use templates as skeletons, not literal output:

- Read `references/AGENTS_TEMPLATE_ROOT.md` only when creating or updating the
  root `AGENTS.md`.
- Read `references/AGENTS_TEMPLATE_MODULE.md` only after a directory is
  confirmed as a nested module that needs its own `AGENTS.md`.
- Replace or remove every placeholder. Final `AGENTS.md` files must not contain
  unresolved `<...>` template markers.

---

## When to run
Run this skill when:

- AGENTS.md is missing, bloated, contradictory, or outdated.
- AGENTS.md needs to be generated, repaired, trimmed, split, or updated.
- A new package/service/module appears.
- Repository structure changes (monorepo growth or split).
- Teams want consistent agent context across diverse stacks.
