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 5.1 | $0.00042 | $0.00422 |
| Opus 5 | $0.00021 | $0.00211 |
| Sonnet 5 | $0.00008 | $0.00084 |
| Haiku 4.5 | $0.00004 | $0.00042 |
Grade A, and why
persona-stats 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 9d 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.

このスキルの実体は hooks/persona-stats.mjs。/persona-stats を検出した
hooks/persona-mode-tracker.mjs がフック内で実行し、整形済みの結果を注入する。
モデル側で計算することは何もない。 注入されたブロックをコードフェンスに入れて そのまま表示するだけ。数値を自分で見積もったり、要約したりしない。
引数
- 引数なし — 現セッションの統計
--share— 1行サマリ--all— 全セッションの集計--since 7d/--since 24h— 期間を区切った集計
数値の意味
- 出力トークン / 入力トークン / ターン数 — セッションログからの実測値
- 削減見込 — レベルごとの平均削減率からの推定値。実測ではない
- オーバーヘッド — SessionStart のルール注入と毎ターンのリマインダの実コスト。 削減見込から差し引かれる
- 正味 — 削減見込 − オーバーヘッド。負の値になることもあり、その場合は 短いセッションでルール注入のほうが高くついたことを意味する
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.

persona-stats is a skill published in the GitHub repository atman-33/workhub (2 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 422 once invoked, about $0.0002 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.
