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 | $0.06892 | $0.06892 |
| Opus 5 | $0.03446 | $0.03446 |
| Sonnet 5 | $0.01378 | $0.01378 |
| Haiku 4.5 | $0.00689 | $0.00689 |
Grade B, and why
claudekit AGENTS.md scanned grade B with 2 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 12d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

claudekit
A toolkit of custom commands, hooks, and utilities for Claude Code. This project provides powerful development workflow tools including git checkpointing, automated code quality checks, specification generation, and AI assistant configuration management. The toolkit is designed to be project-agnostic and enhances Claude Code functionality through shell scripts, commands, and hooks.
Navigating the Codebase
Use the codebase-map tool to understand and navigate the project structure:
Recommended formats:
dsl- For understanding code relationships, imports/exports, functions, and classestree- For exploring directory structure and finding files
Example usage:
# Get code overview with DSL format (shows functions, classes, imports)
codebase-map format --format dsl
# Get directory/file structure with tree format
codebase-map format --format tree
# Focus on specific areas
codebase-map format --format dsl --include "cli/**" --exclude "**/*.test.ts"
The codebase map is automatically provided at the start of each session and can be configured in .claudekit/config.json to filter what's shown.
For complete setup and configuration details, see the Codebase Map Guide.
Build & Commands
This is a TypeScript-based toolkit. Key commands:
- Install:
npm install -g claudekit- Install claudekit globally - Setup:
claudekit setup- Initialize claudekit in your project - Build:
npm run build- IMPORTANT: Run after any code changes to compile TypeScript - Symlinks:
npm run symlinks- Create/update symlinks from.claude/tosrc/for development - Test hooks: Manually trigger by editing files or using Claude Code
- Check shell syntax:
bash -n script.sh - Validate JSON:
jq . settings.json
Important: After making any changes to TypeScript files (hooks, commands, or library code), you MUST run npm run build before testing. The project uses compiled JavaScript from the dist/ directory, not the source TypeScript files.
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.

claudekit AGENTS.md is an instructions file published in the GitHub repository carlrannaberg/claudekit (761 stars, last pushed 5mo ago), licensed MIT. It adds 6,892 tokens to every session, about $0.0345 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
