About this skill
Extracts resources and JavaScript from any installed Electron app (.asar bundle), restoring original sources from .js.map files when available or formatting minified code with Prettier otherwise. Use when user wants to "extract Electron app", "decompile Electron", "get the source code of <app>", "inspect app.asar", "看 Electron 应用源码", "提取 .asar", or asks how a desktop Electron app is built. Skips node_modules and supports both macOS and Windows.
Electron App Extract
Extracts resources and code from an installed Electron app's app.asar. When a .js.map is present, restores the original source files from the embedded sourcesContent; otherwise formats the minified code with Prettier. Source-map paths are resolved relative to the .js.map file first, so bundled paths like ../../src/main.ts restore to readable paths such as restored/src/main.ts instead of hashed placeholders. Always skips node_modules. Works on macOS and Windows.

User Input Tools
When this skill prompts the user, follow this tool-selection rule (priority order):
1. **Prefer built-in user-input tools** exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
2. **Fallback**: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
3. **Batching**: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.
Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.
Script Directory
Scripts in scripts/ subdirectory. {baseDir} = this SKILL.md's directory path. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun. Replace {baseDir} and ${BUN_X} with actual values.
| Script | Purpose |
| ----------------- | ------------------------------------------------------------------------------ |
| scripts/main.ts | App discovery + asar extraction + source-map restoration + Prettier formatting |
When to use
Use this skill whenever the user wants to look inside an installed Electron application or inspect its bundled code. Trigger phrases include:
- "extract Electron app", "decompile this Electron app", "unpack app.asar"
- "show me the source of <app>", "look inside <app>", "how is <app> built"
- "get the source code of Codex / Cursor / Discord / Slack / VS Code / Notion / Obsidian / ChatGPT desktop"
- "提取 Electron 应用", "看 <app> 的源码", "反编译 Electron", "解包 app.asar", "还原 source map"
Both **app name** (e.g., Codex) and **absolute path** (e.g., /Applications/Codex.app, a .asar file, or a Windows install dir) are accepted. The script handles discovery for both platforms.
Workflow
View full documentation
**1. Determine the input.** Ask the user for the app name or path if they haven't given one. If they want a custom output directory, ask for that too.
**2. Run the script.**
${BUN_X} {baseDir}/scripts/main.ts "<app>" [--output <dir>] [--asar <path>] [--force]
Start with --dry-run first if you're unsure whether discovery will find the right bundle — it prints the resolved paths and exits without touching the filesystem.
**3. Handle the result.**
- **Success** → report the output paths and the counts (extracted / restored / formatted).
- **Multiple matches** → the script lists candidates and exits non-zero. Show the user the candidates, ask which one to use (via
AskUserQuestionor the runtime equivalent), then re-run with the chosen absolute path. - **Existing non-empty output dir** → the script refuses without
--force. Ask the user whether to overwrite (--force) or pick a new--outputpath. - **Unsupported platform / no match** → suggest passing
--asar /full/path/to/app.asarif the user knows where the bundle lives.
**4. Point the user at the result.** The default output dir is ~/Downloads/<AppName>-electron-extract/. The most interesting subdirectory depends on what was found:
restored/exists → the original source tree was reconstructed from.js.mapfiles; this is what to read first.- Only
extracted/exists (no maps) → the JS/CSS inextracted/was Prettier-formatted in place; read from there.
