Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.00765 |
| Opus 5.5 | $0.00024 | $0.00306 |
| Sonnet 5.5 | $0.00012 | $0.00153 |
| Haiku 4.5 | $0.00006 | $0.00076 |
Grade A, and why
agents-md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to agents-md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- root
- Write the smallest useful file.
- Verify exact paths and commands exist.
File Setup
- Create
AGENTS.mdat the repository root. - If a Claude-compatible entrypoint is required, symlink
CLAUDE.mdtoAGENTS.md. - Do not maintain divergent
AGENTS.mdandCLAUDE.mdcopies.
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.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agents-md is a skill published in the GitHub repository joao-aires/agent-skills-public (2 stars, last pushed yesterday), licensed MIT. It adds 59 tokens to every session and 765 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to agents-md, differing in 0 lines, and is treated as a copy.
