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 | $0.00047 | $0.05182 |
| Opus 5 | $0.00023 | $0.02591 |
| Sonnet 5 | $0.00009 | $0.01036 |
| Haiku 4.5 | $0.00005 | $0.00518 |
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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agents MD
Contract
| Field | Bound contract |
|---|---|
| Trigger | User asks to set up a repo for agents, add AGENTS.md, audit CLAUDE.md, make a repo agent-friendly, score agent instructions, prune long/generic/stale instructions, or produce a lean pointer-only AGENTS.md |
| Authority | Reversible local: writes only AGENTS.md, CLAUDE.md (or a symlink to AGENTS.md when a target tool reads solely CLAUDE.md), CLAUDE.local.md, .claude/settings.json, .cursor/rules/*.mdc, Cursor hooks.json, and supporting instruction files after user confirmation; rollback is restoring the pre-edit snapshot. No remote mutation. |
| Side effect | Local write to agent instruction files in the repo; no remote, credential, paid, published, deployed, or VCS mutation |
| Done | Repo has working, scored, non-contradictory AGENTS.md for every target tool, plus a CLAUDE.md only when a target tool reads solely CLAUDE.md; every surviving line passes the three-check admission gate (non-discoverable, operationally significant, actionable); lean variants stay under 100 lines with pointer-only sections |
Inputs
- Required: the repository root path to audit or set up.
- Optional: target tool set (defaults to Claude Code, Codex, and Cursor); audit mode (quick or full, defaults to quick); target grade (defaults to 10/12 for quick, A for full); target file path (defaults to root AGENTS.md, then CLAUDE.md if AGENTS.md absent); scope limit (root-only versus hierarchical); owner name for the lean commit attribution line.
Procedure
AGENTS.md files are execution contracts, not knowledge bases. Every line must help an agent execute correctly with minimal context. AGENTS.md is temporary guidance, not permanent configuration: when a recurring issue has a fixable root cause in code or tooling (a lint rule, test, script, or structural change), prefer that fix and keep only the minimum instruction needed until the root cause is solved.
- Discover files and survey discoverability. Find every agent instruction file in the repo:
Also checkfind . \( -name "AGENTS.md" -o -name "CLAUDE.md" -o -name "CLAUDE.local.md" \) 2>/dev/null | sort~/.claude/CLAUDE.md(applies to every session). For monorepos, include workspace-level files. Audit each level independently: root holds universal rules, child files hold directory-specific rules. Then survey source files to learn what is already discoverable: README, PROJECT.md, cursor rules (.cursor/rules/or.cursorrules), Copilot instructions (.github/copilot-instructions.md), GEMINI.md, CI/workflow files, package manager config, CONTRIBUTING.md, anddocs/. Record what an agent can infer from these alone; anything discoverable need not be restated.- Done when: every instruction file is listed and the discoverability survey records what an agent can learn without AGENTS.md.
What ships with it
1 file 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 OutlineDriven/odin-claude-plugin (35 stars, last pushed today), licensed Apache-2.0. It adds 47 tokens to every session and 5,182 once invoked, about $0.0002 per session on Opus 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.
