In plain words

Why use it?
It turns information in a long PDF into a visual relationship chart that can be opened in a browser or saved as a PDF.

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

family-tree 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.

戸籍謄本のPDF文書から人物と関係性を抽出し、裁判所標準形式(相続関係説明図)を 自己完結 HTML(ダブルクリックで開け、⌘P で PDF 化できる単一ファイル)として生成する。 MCP Apps 対応環境(Claude Desktop, Cursor 等)では併せてインライン描画も行う。 監査ログは現在の案件フォルダの ./.claude-bengo/audit.jsonl に記録される。 ./.claude-bengo/ がまだ無ければ、実行時に現在のフォルダへ自動作成される。

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.
