Maintaining AGENTS.md
Goal: concise, actionable agent instructions. Target under 60 lines; never exceed 100.
Workflow
- 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
- 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
- Write the smallest useful file.
- 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
