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 | $0.00107 | $0.00637 |
| Opus 5 | $0.00053 | $0.00318 |
| Sonnet 5 | $0.00021 | $0.00127 |
| Haiku 4.5 | $0.00011 | $0.00064 |
Grade A, and why
startup 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
/startup
業務エージェント（{{TEAM_AGENTS}} など）の標準起動シーケンス。各エージェントの CLAUDE.md から呼ばれる共通スキル。
引数
<agent>：対象エージェント名- 引数なしの場合：cwd から推測（例：cwd 末尾が
agents/<agent>/ならその名前）
実行手順（順番厳守）
<agent> を引数または cwd から確定したうえで：
local-workspace/logs/<agent>/_recent.jsonlの直近エントリを読むagents/<agent>/rules.jsonを読むagents/<agent>/skills/およびAgent-team/skills/のスキル一覧を確認するagents/<agent>/input/の未処理ファイルを確認する
各ステップで読み込んだ内容は エージェントの当面の判断に必要な範囲で頭に入れる。詳細を逐一報告する必要はない（ユーザーから問われたら答える）。
エージェント固有の追加手順
<agent> の CLAUDE.md が「上記 4 ステップの後に追加で実施する事項」を記載している場合は、それも続けて実行する。
出力
ユーザーへの起動メッセージは原則無しで構わない。未処理ファイルや重要な未決事項があれば 1〜2 行で報告。

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.

startup is a skill published in the GitHub repository masa-san-jp/Agent-Aiko (3 stars, last pushed 1mo ago), licensed MIT. It adds 107 tokens to every session and 637 once invoked, about $0.0005 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.
