aicm AGENTS.md

aicm AGENTS.md is an instructions file for Codex, OpenCode from morooka-akira/aicm. It costs 2,658 tokens per session, scanned A, original, MIT.

Project instructions for aicm, a Rust command-line tool that creates context files for several AI coding agents from one shared configuration.

In plain words
What is it for?
Use it when working on aicm, including its Rust implementation and generated files for Cursor, Cline, GitHub Copilot, Claude Code, and Codex.
Why use it?
It keeps agent guidance consistent across tools and tells the agent to protect secrets and respond in Japanese.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

aicm AGENTS.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.

セキュリティ 🔒

機密ファイル

以下のファイルは読み取りや修正を行わないでください:

  • .env ファイル
  • */config/secrets.
  • */.pem
  • API キー、トークン、認証情報を含むファイル

セキュリティプラクティス

  • 機密ファイルをコミットしない
  • シークレットには環境変数を使用
  • 認証情報をログや出力に含めない

アーキテクチャ

設計原則

  • 型安全性: Rust の型システムによるコンパイル時エラー検出
  • メモリ安全性: 所有権システムによる安全なメモリ管理
  • 並行処理: Tokio による効率的な非同期処理
  • 抽象化: トレイトベースのエージェント設計
  • 統一管理: 共通の設定ファイルから各ツール用ファイルを生成

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.
