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 | $0.00368 | $0.05184 |
| Opus 5 | $0.00184 | $0.02592 |
| Sonnet 5 | $0.00074 | $0.01037 |
| Haiku 4.5 | $0.00037 | $0.00518 |
Grade A, and why
pekko-cqrs-es-implementation 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.
How it starts
The opening of the file, as written. The whole thing — 537 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pekko CQRS/ES 実装ガイド
Apache Pekko + Scala 3でCQRS/Event Sourcingを実装する際の具体的なパターン集。
適用条件
このスキルは以下のすべてを満たす場合にのみ使用する:
- プログラミング言語がScala(3.x推奨)であること
- CQRS/Event Sourcingアーキテクチャを採用していること
- Apache Pekko(またはAkka)をアクターフレームワークとして使用していること
上記を満たさない場合は、cqrs-tradeoffs、cqrs-to-event-sourcing、cqrs-aggregate-modelingなど
言語非依存のスキルを使用すること。

コマンド側とクエリ側の分離
| コマンド側 | クエリ側 | |
|---|---|---|
| 目的 | ビジネスルール実行 | 効率的なデータ取得 |
| データストア | DynamoDB(イベントストア) | PostgreSQL(リードモデル) |
| API | GraphQL Mutation | GraphQL Query |
| レイヤー | ドメイン → ユースケース → インターフェースアダプタ | インターフェースアダプタのみ |
| 整合性 | 強い整合性(集約内) | 結果整合性 |
クエリ側にユースケース層はない。 GraphQL自体がユースケースに相当する。

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.

pekko-cqrs-es-implementation is a skill published in the GitHub repository j5ik2o/okite-ai (81 stars, last pushed 4mo ago), licensed MIT. It adds 368 tokens to every session and 5,184 once invoked, about $0.0018 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 2026-09-03.
