agents-md

Creates and maintains concise AGENTS.md and CLAUDE.md project instruction files. Use when asked to create AGENTS.md, update AGENTS.md, maintain agent docs, set up CLAUDE.md, document repository agent conventions, or keep coding-agent instructions minimal and reference-backed.

Draft concise repository instructions

Start a fresh conversation.

Use the agents-md skill to inspect <repository-path> and draft a concise root AGENTS.md. Verify the repository's package manager, commands, documentation paths, conventions, and test layout; reference existing documentation instead of duplicating it.

Required inputs

  • Replace <repository-path> with the local repository to inspect.

SKILL.md

name: agents-mddescription: Creates and maintains concise AGENTS.md and CLAUDE.md project instruction files. Use when asked to create AGENTS.md, update AGENTS.md, maintain agent docs, set up CLAUDE.md, document repository agent conventions, or keep coding-agent instructions minimal and reference-backed.

Maintaining AGENTS.md

Goal: concise, actionable agent instructions. Target under 60 lines; never exceed 100.

Workflow

  1. Inspect before writing:
    • package manager: lock files and manifests
    • commands: package.json, Makefile, task runners, CI workflows
    • docs/specs/policies: README.md, CONTRIBUTING.md, docs/, specs/, policies/, SECURITY.md, .github/
    • conventions: current code patterns, test layout, generated files, legacy areas to avoid
  2. Choose scope:
    • root AGENTS.md: repo-wide defaults
    • nested AGENTS.md: only when a subtree has different commands or rules
    • closest instruction file wins; keep narrower files shorter than root files
  3. Write the smallest useful file.
  4. Verify exact paths and commands exist.

File Setup

  • Create AGENTS.md at the repository root.
  • If a Claude-compatible entrypoint is required, symlink CLAUDE.md to AGENTS.md.
  • Do not maintain divergent AGENTS.md and CLAUDE.md copies.

Default Sections

Use only sections that add non-obvious value.

# Agent Instructions

## Package Manager
- Use **pnpm**: `pnpm install`

## Commands
| Task | Command |
|------|---------|
| Test file | `pnpm vitest run path/to/file.test.ts` |
| Lint file | `pnpm eslint path/to/file.ts` |

## External References
| Need | File |
|------|------|
| Setup | `CONTRIBUTING.md` |
| Architecture | `docs/architecture.md` |
| Security policy | `SECURITY.md` |

## Key Conventions
- Generated files: update with `pnpm generate`; do not edit by hand.

## Commit Attribution
AI commits MUST include:
```
Co-Authored-By: (the agent's name and attribution byline)
```

Writing Rules

  • Use headings, bullets, and tables; avoid paragraphs.
  • Use repo-relative paths; avoid vague references like "see docs".
  • Reference existing docs/specs/policies instead of copying them.
  • List exact external files for setup, architecture, API specs, security, release, and policy docs when they exist.
  • Prefer file-scoped test/lint/typecheck commands; include full builds only when no narrower command exists.
  • Put commands in tables when there is more than one.
  • Keep one rule per bullet.
  • Keep rationale out unless it prevents a likely mistake.
  • Do not restate linter, formatter, or typechecker config.
  • Do not list installed skills or plugins.
  • Do not include generic quality slogans.

External Reference Rules

Good:

## External References
| Need | File |
|------|------|
| API contract | `docs/api.md` |
| Release process | `docs/releasing.md` |

Anti-Patterns

  • welcome text, intros, conclusions, or pleasantries
  • long prose explaining why instructions matter
  • duplicated content from README.md, CONTRIBUTING.md, or policy docs
  • project-wide commands when file-scoped commands are available
  • nested AGENTS.md files that repeat root instructions
