What is agent-skills CLAUDE.md?

A guide to a repository of reusable instructions for coding agents. Its skills are plain Markdown files that describe domain knowledge, workflows, standards, and project conventions.

Use it when creating, maintaining, or navigating agent skills and when following the repository's structure and documentation conventions.

It gives agents repeatable guidance without requiring a build system or runtime, and keeps each skill organized with its supporting references.

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	$0.01117	$0.01117
Opus 5	$0.00558	$0.00558
Sonnet 5	$0.00223	$0.00223
Haiku 4.5	$0.00112	$0.00112

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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Skills

Reusable knowledge base for AI coding agents. Skills = packaged domain expertise (standards, conventions, patterns) that agents absorb and follow.

Pure Markdown. No build. No runtime. Agent-agnostic.

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.
