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 | $0.01372 | $0.01372 |
| Opus 5 | $0.00686 | $0.00686 |
| Sonnet 5 | $0.00274 | $0.00274 |
| Haiku 4.5 | $0.00137 | $0.00137 |
Grade A, and why
claude-kit 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 5d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
A collection of powertools for Claude Code including specialized agents, skills, and MCP server configuration. Each is a markdown file with YAML frontmatter defining its configuration, followed by detailed behavioral instructions.
- Agents: Specialized subagents for complex tasks (code review, testing, debugging, etc.)
- Skills: User-invocable workflows and commands (invoke with
/skill-name) - MCP Config: Pre-configured MCP servers for extended capabilities
Commands
# Install dependencies
pnpm install
# Lint and format code
pnpm biome check . # Check for issues
pnpm biome check . --write # Fix issues automatically
# Setup and installation
pnpm bootstrap # Interactive setup - creates symlinks in ~/.claude/ and ~/.mcp.json
pnpm install-statusline # Interactive statusline installer - configure Claude Code statusline
# Run tests
pnpm test:docker # Interactive test runner with Docker

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.

claude-kit CLAUDE.md is an instructions file published in the GitHub repository ruchernchong/claude-kit (0 stars, last pushed 3mo ago), licensed MIT. It adds 1,372 tokens to every session, about $0.0069 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
