durable-objects SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
durable-objects from daishiman/harness-dev is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add daishiman/harness-dev/durable-objects@git:20261002.c0e127dPins git:20261002.c0e127d in mdr.lock. Pin the fingerprint instead.

Cloudflare Durable Objects の実装とレビューに使用する。チャットルーム、マルチプレイ、予約システムなどの状態を持つ協調処理、RPC methods、SQLite storage、alarms、WebSockets、Workers統合、wrangler設定、Vitestでのテストを扱う。事前学習の知識より最新のCloudflare docsの取得を優先する。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> 本ファイルは cloudflare/skills（Apache-2.0）を基に改変しています。詳細は リポジトリルートの ATTRIBUTION.md を参照。 # Durable Objects の実装・レビュー Durable Objectsを使い、Cloudflare edge上に状態を持つ協調型アプリケーションを実装する。 ## 最新情報の取得先 Durable Objects APIsや設定は更新されるため、**事前学習の知識より最新の公式情報を優先する**。API signature、設定項目、制限値を記憶だけで断定しない。 正本は [`cloudflare` Skill の「最新情報の取得先」](../cloudflare/SKILL.md#最新情報の取得先)(docs MCP 第一手段、不通時の復旧、workers-types / config-schema の取得方法)。ここには本Skill固有の取得先だけを書く。 | 取得先 | 取得方法 | 使う場面 | |--------|----------|---------| | **Cloudflare docs (MCP)** | `cloudflare-docs` MCPで `durable-objects` + API名(`sql.exec`、`setAlarm` 等)を検索 | **既定の第一手段**。API reference、制限値、compatibility date要件 | | Durable Objects docs (Web) | `https://developers.cloudflare.com/durable-objects/`(`api/`、`best-practices/`、`examples/`) | MCP不通時 | 実装前に該当ページとプロジェクトのWrangler config schema / Workers typesを確認する。本Skillと最新の公式情報が食い違う場合は公式情報を優先し、不明なAPIや設定を推測で補わない。 ## 使う場面 - 協調処理のために新しいDurable Object classを作る - RPC methods、alarms、WebSocket handlersを実装する - 既存のDOコードをBest Practicesに照らしてレビューする - `wrangler.jsonc` / `wrangler.toml`にDO bindingsとmigrationsを設定する - `@cloudflare/vitest-pool-workers`でテストする - sharding戦略やparent-child関係を設計する ## 詳細リファレンス …

How to install
mdr add daishiman/harness-dev/durable-objects@sha256:51e0f24994ab1bf6The line at the top of this page pins the label git:20261002.c0e127d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
