What is llm-code CLAUDE.md?

Instructions for a repository containing more than 40 reusable agent skills for coding tools such as Claude Code, GitHub Copilot, and Cursor. They describe the repository layout and commands for creating, checking, and packaging a skill.

Use them to understand the skill repository, scaffold a new skill, validate its structure, package it for distribution, and follow its folder conventions.

They give contributors a consistent way to add and validate skills in a documentation-focused project with no runtime build or test process. This avoids malformed skill folders and missing required files.

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	$0.01589	$0.01589
Opus 5.5	$0.00636	$0.00636
Sonnet 5.5	$0.00318	$0.00318
Haiku 4.5	$0.00159	$0.00159

Security

Grade A, and why

llm-code 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 Repo Is

A collection of 40+ Agent Skills for AI coding tools (Claude Code, GitHub Copilot, Cursor). Skills are installed into user projects via npx add-skill itechmeat/llm-code.

Key Commands

# Scaffold a new skill
python skills/skill-master/scripts/init_skill.py <skill-name>

# Validate a skill's structure
python skills/skill-master/scripts/quick_validate_skill.py skills/<skill-name>

# Package a skill for distribution
python skills/skill-master/scripts/package_skill.py skills/<skill-name>

There are no build or test commands — this is a documentation/skill collection with no runtime dependencies.

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.
