## Description

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
