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 | $0.00055 | $0.00607 |
| Opus 5 | $0.00028 | $0.00303 |
| Sonnet 5 | $0.00011 | $0.00121 |
| Haiku 4.5 | $0.00006 | $0.00061 |
Grade A, and why
persona 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 7d 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.
What it actually says
persona
応答口調のキャラクターと圧縮レベルを切り替えるスキル。
重要: キャラクター定義を読みに行かないこと
現在のキャラクターの口調定義は、SessionStart フックが既にコンテキストへ注入済み。
characters/ 配下や core/ 配下のファイルを読む必要は一切ない。読むと、使っていない
キャラクターとレベルの定義まで丸ごとコンテキストに載り、このプラグインの目的である
トークン削減を損なう。
キャラクターの切替も、フック（hooks/persona-mode-tracker.mjs）が処理する。
このスキルはコマンドの説明のためだけに存在する。
コマンド
/persona— キャラクター一覧と現在の状態を表示する/persona <キャラクター>— キャラクターを切り替える（レベルは維持）/persona <レベル>— レベルを切り替える（キャラクターは維持）/persona <キャラクター> <レベル>— 両方を切り替える/persona <キャラクター> 一時— このセッション限りの切替/persona off— 解除
レベル名はキャラクターごとに異なる。/persona の一覧に各キャラクターの
3レベルが表示される。
設定の永続化
一時 を付けない切替は ~/.claude/persona.json に保存され、次回以降のセッションにも
自動で反映される。設定し直す必要はない。
環境変数 PERSONA_DEFAULT（<キャラクター>:<レベル> 形式、または off）が
設定されている場合はそちらが優先され、保存した設定は反映されない。
その状況では切替時に警告が出る。
キャラクターの追加
/persona-new <id> で作成する。保存先は ~/.claude/personas/<id>/character.md で、
プラグイン更新の影響を受けない。プラグイン配下の characters/ には書き込まない。
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 is a skill published in the GitHub repository atman-33/workhub (2 stars, last pushed 2d ago), licensed MIT. It adds 55 tokens to every session and 607 once invoked, about $0.0003 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.
