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 | $0.00025 | $0.00703 |
| Opus 5 | $0.00013 | $0.00351 |
| Sonnet 5 | $0.00005 | $0.00141 |
| Haiku 4.5 | $0.00003 | $0.00070 |
Grade A, and why
aiko-new 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.
What it actually says
/aiko-new <name>
新しい名前付き人格を作成してアクティブにします。
スラグのルール
- 半角英数とハイフンのみ（例:
work,teacher,casual-aiko） - 予約名
origin,override,defaultは使用不可 - すでに同名の人格ディレクトリが存在する場合は作成不可（上書きしません）
手順
-
<name>の妥当性を確認します- 半角英数とハイフン以外が含まれる場合：
エラー：スラグ名には半角英数とハイフンのみ使用できます。例: work, teacher, casual-aiko - 予約名（
origin,override,default）の場合：エラー：「<name>」は予約名のため使用できません。 overrides/<name>/persona.mdが既に存在する場合：エラー：「<name>」はすでに存在します。/aiko-select <name> で切り替えられます。
- 半角英数とハイフン以外が含まれる場合：
-
~/.aiko/persona/overrides/<name>/ディレクトリを作成します -
~/.aiko/persona/origin/persona.mdの内容をoverrides/<name>/persona.mdにWriteでコピーします -
overrides/<name>/user.mdをname:/address:の雛形で作成します -
必要に応じて
overrides/<name>/README.mdを作成します -
~/.aiko/active-personaを<name>でWriteします（末尾改行あり） -
~/.aiko/modeをoverrideでWriteします（末尾改行あり） -
~/.aiko/override-history.jsonlに追記します{"ts":"YYYY-MM-DDTHH:MM:SS","action":"new-persona","name":"<name>","base":"origin","summary":"新しい人格 <name> を作成"} -
~/.aiko/logo.txtを Read して応答冒頭にロゴを表示します -
完了を報告します
人格「<name>」を作成しました（overrides/<name>/persona.md）。
現在のプレフィックスは Aiko-<name>: です。
/aiko-override <指示> でカスタマイズを始められます。
注意
- 作成後は自動的に
<name>がアクティブになります（選択は不要です） - ベースは常に
persona/origin/persona.mdです（aiko-override.mdからのコピーは行いません）
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.

aiko-new is a skill published in the GitHub repository masa-san-jp/Agent-Aiko (3 stars, last pushed 1mo ago), licensed MIT. It adds 25 tokens to every session and 703 once invoked, about $0.0001 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.
