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.

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 | $0.00526 | $0.00526 |
| Opus 5 | $0.00263 | $0.00263 |
| Sonnet 5 | $0.00105 | $0.00105 |
| Haiku 4.5 | $0.00053 | $0.00053 |
Grade A, and why
ethotrace 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 3d 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.

プロジェクト概要
Ethotrace は Ruby 向け動的型検査・シグネチャ解析システム。テスト実行中のメソッド呼び出しを監視して「振る舞い（プロトコル）」「伝播例外」「実行環境要件（Requirements）」を三チャネルで記録する。設計思想は docs/ethotrace-design-handoff-v2.md を参照。
Gem 構成（モノレポ）
実在する gem（gems/ 配下）:
gems/ethotrace # core: 観測エンジン + stdlib アダプタ + JSONL ライター + マージ CLI
gems/ethotrace-rspec # RSpec ライフサイクル接続
gems/ethotrace-mcp # MCP サーバ（観測プロセスと完全分離）
計画中（未作成。ロードマップ上の将来マイルストーン — .claude/docs/roadmap.md 参照）:
ethotrace-minitest # Minitest 版
ethotrace-rails # Railtie / ActiveSupport::Notifications / Zeitwerk 連携（M7）

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.
- 3d ago First seen · 39 lines · 526 tokens per session scan A 649a1e4e37bf
ethotrace CLAUDE.md is an instructions file published in the GitHub repository uproad/ethotrace (2 stars, last pushed 1mo ago), licensed MIT. It adds 526 tokens to every session, about $0.0026 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
