What is skills AGENTS.md?

A repository guide for reusable skills made for coding agents such as Claude Code and Codex.

It helps developers add or maintain individual agent skills and keep their metadata, folders, and supporting files consistent.

It defines where skills belong, how they must be structured, and which validation command to run before committing changes.

Token cost

What it costs to keep this loaded

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	$0.00193	$0.00193
Opus 5.5	$0.00077	$0.00077
Sonnet 5.5	$0.00039	$0.00039
Haiku 4.5	$0.00019	$0.00019

Security

Grade A, and why

skills 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 2mo ago.

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.

What it actually says

Repository conventions

Agent Skills for coding agents (Claude Code, Codex, and other Agent Skills–compatible hosts). One skill per folder.

Installable skills live at skills/<name>/SKILL.md; frontmatter name must equal the folder name.
description is the trigger surface — what the skill does and when to use it — in 200 characters or fewer (the Claude.ai limit).
Keep each skill self-contained. Reference only files inside its own folder (references/, scripts/, assets/); never a sibling skill or a ../ path. Skills install individually, so anything outside the folder won't come along.
agents/openai.yaml carries the Codex display block (interface:) and invocation policy:.
Run npm run validate before committing. To add a skill, copy an existing one and edit it.

Changes

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.
