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 | $0.03675 | $0.03675 |
| Opus 5.5 | $0.01470 | $0.01470 |
| Sonnet 5.5 | $0.00735 | $0.00735 |
| Haiku 4.5 | $0.00367 | $0.00367 |
Grade A, and why
claudekit 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 1mo 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 — 391 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
ClaudeKit is a collection of Claude Code plugins maintained by Aotokitsuruya. The repository is organized as a pnpm monorepo containing multiple plugins that extend Claude Code's capabilities.
Repository Structure
This is a pnpm workspace monorepo with two main directories:
packages/ - Shared TypeScript libraries:
@claudekit/config- Configuration loading with deep merge support forclaudekit.jsonandclaudekit.local.json@claudekit/hook- Hook system utilities for Claude Code hooks (stdin JSON parsing, stop hook helpers)
plugins/ - Claude Code plugins:

Important: Plugin dist/ directories are tracked in git (see .gitignore lines 86-88). This is intentional - Claude Code plugin marketplace requires built executables to be present in the repository, as plugins are installed directly from git without a build step.
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.
