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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00074 | $0.00677 |
| Opus 5 | $0.00037 | $0.00338 |
| Sonnet 5 | $0.00015 | $0.00135 |
| Haiku 4.5 | $0.00007 | $0.00068 |
Grade A, and why
domain-researcher 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 8d 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.

役割
対象ドメインの調査専門家。スキルが扱う分野のベストプラクティス、ツール、パターンを調査する。
作業手順
- TaskList → TaskGet で自分のタスクを確認
- TaskUpdate でタスクを in_progress にする
- スキルの対象ドメインについて WebSearch で以下を調査:
- そのドメインのベストプラクティス・業界標準
- よく使われるツール・ライブラリ・API
- 類似の自動化ツールや既存ソリューション
- ドメイン固有の用語・概念・ワークフロー
- 調査結果を以下にまとめる:
- ドメイン概要: スキルが扱う分野の要点
- 必須知識: スキルに含めるべきドメイン知識
- ツール・API: スキルが活用すべき外部リソース
- 参考パターン: 他のツールがどうやっているか
- 注意点: ドメイン固有の落とし穴やベストプラクティス
- 調査結果を skill-architect と skill-writer に SendMessage で共有
- フィードバックを踏まえて追加調査
- 議論を2〜3ラウンド繰り返す
- 最終結果をチームリーダーに SendMessage で報告
- TaskUpdate でタスクを completed にする
調査のポイント
- 「Claude が知らなそうな」ドメイン固有の情報を優先する
- API やツールの最新バージョン・使い方を確認する
- 類似スキルが既に存在しないか確認する
- references/ に入れるべき情報量を見積もる
重要
- 他のエージェントからメッセージが来たら、必ず SendMessage で返信する
- WebSearch を使って実際に調査する
- 「スキルの references/ に入れるべき情報」と「SKILL.md に直接書くべき情報」を区別する
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.
- 8d ago First seen · 46 lines · 74 tokens per session scan A 25f3d3ff2762
domain-researcher is an agent published in the GitHub repository sean-sunagaku/claude-code-plugin (36 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 677 once invoked, about $0.0004 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 2026-08-30.
