What is agent-skills CLAUDE.md?

Repository instructions for agent-skills, a collection of Markdown instruction files used by Claude Code, Codex, and other coding agents. The repository manages guidance rather than executable software.

Use them when maintaining this skills repository, adding or changing skill documents, or working with its code-review, planning, installation, and delegation guidance.

They document the repository’s structure and the roles of its skills, making it easier to find the right instruction and keep the collection consistent.

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	$0.02514	$0.02514
Opus 5.5	$0.01006	$0.01006
Sonnet 5.5	$0.00503	$0.00503
Haiku 4.5	$0.00251	$0.00251

Security

Grade A, and why

agent-skills CLAUDE.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 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.
