为 Electron 桌面应用设计、实现和验证增量自动更新，覆盖 macOS Sparkle、签名、appcast、发布产物与失败拦截。用户提到增量更新、Sparkle、检查更新、appcast、DMG 更新或 delta updater 时使用。.
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
# Electron 增量更新 · Electron Delta Updates 为现有 Electron 应用交付可验证的增量更新链路；以用户实际安装包、公开更新源和安装结果为准，而不是以 CI 成功为准。 ## Triggers ### Activate when - 用户说“给这个 Electron App 加增量自动更新”或“检查更新一直转圈”。 - 用户提到 macOS Sparkle、appcast、DMG、blockmap、签名、公证或 delta 更新包。 - User asks to “add a delta updater”, “ship Sparkle updates”, or “verify an Electron update release”. ### Do not activate when - 用户只想修改版本号、更新日志或普通下载页；使用版本管理或发布工作流。 - 用户要做网页热更新、PWA 缓存更新或移动端 OTA；使用相应平台的更新机制。 ## Workflow (MANDATORY) **Follow these steps in order.** ### Step 0: Establish the update contract - 确认目标平台、包格式、当前更新器、更新源、签名责任方、发布渠道和回滚预期。 - 只有在明确排除完整包时，才把 macOS delta-only 作为发布承诺。 - 将检查、下载/暂存、安装交接、重启后验证拆成四个状态。 - 处理 macOS Sparkle 时读取 `references/electron-macos-delta.md`；修改发布流水线前读取 `references/release-verification.md`。 ### Step 1: Make checks bounded and recoverable - 每个更新服务只保留一个进行中的检查。 - 将 `AbortSignal` 传入包含 appcast 请求在内的每一层网络调用。 - 超时后终止请求，等待旧更新状态和连接收敛，再允许后续重试。 - 配置更新器自己的网络会话，避免把开发者终端代理当作运行时配置。 - 每次超时、下载失败或 feed 格式错误后，界面都保留可重试状态。 ### Step 2: Enforce the artifact policy - 生成按架构区分的 feed 条目，并让每个 delta 对应明确的源版本和目标版本。 - 暂存前核对签名、长度、架构和 URL。 - delta-only 模式遇到完整包回退时停止当前链路，展示手动安装路径，避免静默下载更大的归档。 …

How to install
mdr add lovstudio/skills/lov-electron-delta-updater@sha256:03e7046e6f38d5c1The line at the top of this page pins the label v0.2.1, 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.
