What is skills CLAUDE.md?

Repository instructions for a collection of reusable AI-agent skills, including rules for verifying facts, reporting uncertainty, using English, and documenting test findings.

Use them when contributing code or documentation, checking facts, running tests, or recording bugs and testing results.

They set expectations for how agents should investigate, communicate, and update this skills repository.

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	$0.01013	$0.01013
Opus 5.5	$0.00405	$0.00405
Sonnet 5.5	$0.00203	$0.00203
Haiku 4.5	$0.00101	$0.00101

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.

CLAUDE.md

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

Agent Behavior Rules

Verify before answering: Always confirm facts through code, tests, or documentation before stating them. Do not guess or assume.
Surface uncertainty: When something is unclear or unverified, raise it explicitly for discussion rather than picking an answer and moving on.
Language: All documentation, code, and git operations must be in English.
Document during testing: When a bug is found and fixed during a testing session, immediately ask whether to record it in the relevant docs/testing/ file. Do not wait until the end of the session. After a testing session wraps up, check docs/testing/ and offer to update it with any findings not yet recorded.

Project Overview

Agent Skills repository for the aurehub organization. Skills are structured Markdown packages that teach AI coding agents how to perform specific tasks, following the Agent Skills specification.

Repository Structure

skills/           # Each subdirectory is one skill
  <skill-name>/
    SKILL.md              # Required: YAML frontmatter + agent instructions
    SKILL.tests.yaml      # Test suite (smoke/full suites)
    README.md             # User-facing setup guide
    references/           # Progressive-disclosure docs loaded on demand
    scripts/              # Executable helpers (Node.js, Bash, etc.)
template/
  SKILL.md.template        # Boilerplate for creating new skills
scripts/
  publish-clawhub.sh    # Publish skills to ClawHub registry

Skill Format

Every skill requires a SKILL.md with YAML frontmatter:

---
name: my-skill-name          # lowercase, hyphens, matches directory name
description: What this skill does and when to trigger it
license: MIT
metadata:
  author: aurehub
  version: "1.0"
---

Body follows progressive disclosure: frontmatter (always loaded) -> body (on trigger) -> references/ (on demand).

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.
