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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00161 | $0.01207 |
| Opus 5 | $0.00081 | $0.00603 |
| Sonnet 5 | $0.00032 | $0.00241 |
| Haiku 4.5 | $0.00016 | $0.00121 |
Grade A, and why
genshijin-crew 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
genshijin-crew = 原始人形式で出力する3 subagent preset。役割は Anthropic デフォルト (Explore、編集系 agent、reviewer) と同じ。差分は返ってくる tool-result が圧縮済 → 主コンテキスト消費が委譲毎に縮む。
genshijin-crew vs 代替の使い分け
| タスク | 使用 |
|---|---|
| 「Xの定義どこ / Yを呼ぶ箇所 / Zの全用法」 | genshijin-investigator |
| 同上 + アーキテクチャ解説/提案も欲しい | Explore (vanilla) |
| Surgical編集、≤2ファイル、スコープ明確 | genshijin-builder |
| 新機能 / 3+ファイル / cross-cutting refactor | 主スレッド or feature-dev:code-architect |
| Diff/branch/file の bug レビュー | genshijin-reviewer |
| rationale + alternatives 付き深いコードレビュー | Code Reviewer (vanilla) |
| 1行回答済の確実な内容 | 主スレッド、subagent不要 |
判断基準: subagent 出力を1/3トークンで欲しいなら genshijin-crew、散文で欲しいなら vanilla。
なぜ存在するか (実利)
Subagent tool-result は主コンテキストに verbatim 注入される。Vanilla Explore が散文2k tokens 返すと毎回主コンテキスト2k消費。同じ発見が genshijin-investigator だと約700 tokens。1セッション20委譲で context exhaustion vs タスク完了の差。
出力契約
主スレッドが agent 別に依拠できる形式:
genshijin-investigator
<Header>:
- path:line — `symbol` — short note
集計: <counts>。
or No match. 必ずファイルパス先頭、行番号付、シンボルはバッククォート。path:\d+ で grep可能。
genshijin-builder
<path:line-range> — <change ≤10語>。
verified: <re-read OK | mismatch @ path:line>。
or 以下のいずれか: too-big. / needs-confirm. / ambiguous. / regressed. (terminal first token)。
genshijin-reviewer
path:line: <emoji> <severity>: <問題>. <修正>.
totals: N🔴 N🟡 N🔵 N❓
or No issues. ファイル → 行昇順。
チェイニングパターン
位置特定 → 修正 → 検証 (最頻):
genshijin-investigatorで site list 取得- 主スレッドが1-2 site選び
genshijin-builderにパス渡す genshijin-reviewerが diff 監査
並列スカウト (調査が広い時):
1メッセージで genshijin-investigator 2-3個並列起動 (異なる角度: defs vs callers vs tests)。主スレッドで集約。
単発編集 (sit既知時):
investigator スキップ。genshijin-builder に直接 path:line 渡す。
禁止事項
- ファイル未特定で
genshijin-builder使用禁止。先に investigator 起動 → でないと主スレッドがコンテキスト渡しでトークン消費。 - 5ファイル refactor で
genshijin-investigator → genshijin-builderチェーン禁止。Builder はtoo-big.返却 → ターン浪費。 genshijin-reviewerに「全般フィードバック」依頼禁止 → findings のみ返却、アーキテクチャ意見なし。それ用はCode Reviewer。- 散文期待禁止。genshijin-crew 出力は構造化、時に cryptic。人間が直読する場合は主スレッドが言換え。
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.
- 12d ago First seen · 80 lines · 161 tokens per session scan A e1881d3edcc6
genshijin-crew is a skill published in the GitHub repository InterfaceX-co-jp/genshijin (325 stars, last pushed 27d ago), licensed MIT. It adds 161 tokens to every session and 1,207 once invoked, about $0.0008 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.
