CLAUDE.md

cook CLAUDE.md is an instructions file for Claude Code from PJuniszewski/cook. It costs 1,616 tokens per session, scanned A, original, MIT.

Project instructions for a Claude Code plugin called juni, which combines structured feature-development workflows with a safety guide for JSON data. It uses project context, routing policies, and operational rules.

In plain words
What is it for?
Use them when developing features with juni or handling JSON data through its cook and guard workflows.
Why use it?
They help the agent follow the project's workflow and safety rules instead of relying only on informal prompts.

Instructions file for Claude Code

Written for Claude Code: Claude Code plugin machinery. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is PJuniszewski/cook's own configuration. It tells Claude Code how to work on cook itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cook configures →

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

cook 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.

juni Plugin Project Rules

Purpose

This repo contains the juni plugin - a Claude Code plugin suite combining:

  • /juni:cook - Structured feature development workflows
  • /juni:guard - Epistemic safety for JSON data

Architecture: Multi-Layer Context System

Cook uses a layered approach combining narrative context with operational contracts and explicit policies:

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.
