One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
A source map located at .vite/main/index.js.map contains a relative source path entry ../../src/main.ts. Where in the output directory will this file be reconstructed?

The instructions your model reads when the skill loads.
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.
When this skill prompts the user, follow this tool-selection rule (priority order):
AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.
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 |
Use this skill whenever the user wants to look inside an installed Electron application or inspect its bundled code. Trigger phrases include:
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.
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.
