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 | $0.00030 | $0.01041 |
| Opus 5 | $0.00015 | $0.00521 |
| Sonnet 5 | $0.00006 | $0.00208 |
| Haiku 4.5 | $0.00003 | $0.00104 |
Grade A, and why
aiko-select 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.
What it actually says
/aiko-select <name>
人格を切り替えます。
引数パターンと動作
| 引数 | 動作 |
|---|---|
origin |
mode を origin に、active-persona を空に |
override または 引数なし |
mode を override に、active-persona を空に |
<slug> |
overrides/<slug>/persona.md が存在すれば mode を override に、active-persona を <slug> に |
手順
-
引数を確認します
-
originの場合:~/.aiko/modeをoriginに書き込みます~/.aiko/active-personaを空にします(Writeで空文字列)- ロゴを表示して報告します
アイコ(オリジナル)に切り替えました。プレフィックスは Aiko-origin: です。
-
overrideまたは引数なしの場合:~/.aiko/modeをoverrideに書き込みます~/.aiko/active-personaを空にします- ロゴを表示して報告します
アイコ(カスタマイズ)に切り替えました。プレフィックスは Aiko-override: です。
-
その他の
<slug>の場合:タイポ・大文字小文字の揺れがあってもなんとなく察して解決します。
~/.aiko/persona/overrides/配下でpersona.mdを含むディレクトリ名を候補集合として、以下を上から判定し、最初にヒットしたものを採用します。段階 判定 例 動作 1. 完全一致(大小無視・前後空白除去) normalize 後に完全一致 Work→work確認なしで切替 2. 単一の prefix 一致 入力で始まる候補が 1 個 wo→work「 <候補>ですね?」と 1 行確認3. 単一の部分一致 入力を含む候補が 1 個 ud→study同上 4. 単一の編集距離 ≤ 2 Levenshtein 距離 ≤ 2 の候補が 1 個 worl→work同上 5. 複数候補にヒット 2 個以上 w→work/writing候補列挙して再入力 6. ヒットなし 0 個 xyz候補列挙して再入力 段階 2〜4 の確認:
「<入力>」は「<候補>」のことですね? 切り替えてよろしいですか?ユーザー同意で続行、否定なら全候補を列挙して再入力を促します。
段階 5・6 の応答:
「<入力>」に該当する人格が <複数 / 見つかり> ません。 候補: origin ★ <active> <slug> <slug> もう一度 /aiko-select <name> で指定してください。解決後の切替動作:
~/.aiko/modeをoverrideに書き込みます~/.aiko/active-personaを<slug>に書き込みます(末尾改行あり)- ロゴを表示して報告します
人格「<slug>」に切り替えました。プレフィックスは Aiko-<slug>: です。
注意
- 切替後は次の発話から新しい人格ファイルに従います
active-personaファイルが存在しない場合はWriteで新規作成します
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-select is a skill published in the GitHub repository masa-san-jp/Agent-Aiko (3 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 1,041 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.
