Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

vibes 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 2d 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 Code Prompting Guide

Basic Usage

claude
claude "Your prompt here"

Claude Code Specific Features

Slash Commands

Claude Code supports custom slash commands. Create them in your project root:

# Example: Add to your project's .claude/commands/
/slides - Regenerate presentation slides

Memory Management

Claude Code maintains context across conversations. Use CLAUDE.md files to provide persistent context.

Agentic Prompting Techniques

1. Multi-Step Planning

Claude excels at breaking down complex tasks:

claude "I need to implement user authentication. First, create a plan with all the necessary steps."

2. Code Analysis and Refactoring

Leverage Claude's code understanding:

claude "Analyze this codebase structure and suggest architectural improvements: [paste code or file paths]"

3. Interactive Development

Build solutions iteratively:

claude "Start building a React component for user profiles. Begin with the basic structure."
# Then: "Add form validation to the profile component"
# Then: "Add state management with useReducer"

4. Documentation Generation

Claude is excellent at creating comprehensive docs:

claude "Generate API documentation for this Express.js router: [code]"

5. Test-Driven Development

Use Claude to guide TDD workflows:

claude "Write failing tests for a user authentication service, then implement the service to make them pass"

Advanced Techniques

System Thinking

claude "Think like a system architect. How would you design a scalable microservices architecture for an e-commerce platform?"

Code Review Partner

claude "Act as a senior code reviewer. What potential issues do you see in this implementation? Consider security, performance, and maintainability."

Debugging Assistant

claude "I'm getting this error: [error message]. Here's my code: [code]. Walk me through debugging this step by step."

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.
