task-composer: Instructions file for Claude Code

CLAUDE.md

task-composer CLAUDE.md is an instructions file for Claude Code from HNakamura33/task-composer. It costs 3,588 tokens per session, scanned A, original, Apache-2.0.

Project instructions for learning Rust while building a task-management library based on a directed acyclic graph, a structure where tasks can depend on earlier tasks without forming cycles. The instructions favor hints and explanations over writing code for the learner.

In plain words
What is it for?
Use them to explain Rust concepts, work through compiler errors, build the library gradually, and encourage tests.
Why use it?
They turn implementation errors and new Rust concepts into guided learning steps rather than simply supplying finished code.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is HNakamura33/task-composer's own configuration. It tells Claude Code how to work on task-composer 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 task-composer 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

task-composer 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 2mo 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.

Task Composer

DAGベースのタスク管理ライブラリ(Rust学習プロジェクト)

Claudeへの指示

このプロジェクトはRust学習を目的としています。以下の点を意識してサポートしてください:

  • コードを直接書かない: ヒントやシグネチャを提示し、ユーザーが自分で実装できるようガイドする
  • 概念を説明する: 新しいRustの概念が出てきたら、図や例を使って分かりやすく説明する
  • エラーを学習機会に: コンパイルエラーが出たら、なぜそのエラーが起きるのかを丁寧に解説する
  • 段階的に進める: 一度に大量のコードを提示せず、小さなステップで進める
  • 質問を促す: ユーザーが理解を深められるよう、適宜質問を投げかける
  • テストを重視: 実装後は必ずテストを書くよう促す

プロジェクト概要

有向非巡回グラフ(DAG)を使ってタスクの依存関係を管理するRustライブラリ。

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.
