What is skills CLAUDE.md?

Repository instructions for creating and publishing self-contained coding-agent skills in the MapleAI-Tech collection.

They guide creation of skill files, updates to the README catalogue, installation commands, and usage examples.

They give contributors a consistent file layout and the steps needed to make a new skill discoverable and installable.

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	$0.00443	$0.00443
Opus 5.5	$0.00177	$0.00177
Sonnet 5.5	$0.00089	$0.00089
Haiku 4.5	$0.00044	$0.00044

Measured 2mo ago against content hash 3acc3102fc02, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

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 it actually says

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What This Repo Is

An open-source collection of Claude Code skills published by 青枫数科 (MapleAI-Tech). Skills are self-contained SKILL.md files that define behavior for the Claude Code CLI. There is no build system, no package manager, and no tests — each skill is a single Markdown file with structured XML-style sections.

Repository Layout

skills/
├── {skill-name}/
│   └── SKILL.md      # The entire skill definition

Users install by copying skill directories into ~/.claude/skills/.

Adding a New Skill

Create skills/{name}/SKILL.md
Add a row to the skills table in README.md
Add the cp line to the install section in README.md
Add usage examples under a new ## {name} heading in README.md

SKILL.md Structure Convention

Every skill file uses this structure (see existing skills for reference):

Frontmatter (name, description) — used for skill registry
<Purpose> — one-sentence mission
<Use_When> / <Do_Not_Use_When> — trigger conditions
<Project_Structure> — files and directories the skill manages
<Commands> — each slash command with step-by-step instructions
<Tool_Usage> — which Claude Code tools the skill uses
<Examples> — <Good> and <Bad> with "Why good/bad" annotations
<Escalation_And_Stop_Conditions> — edge cases and guardrails
<Final_Checklist> — verification items

Existing Skills

Skill	Purpose
chuxin	Product brain — roadmap init, daily briefings, competitive research
doc-align	Document alignment — scan, index, and archive all `.md` files into `/docs`

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.
