# Electron CLI Integration Skill

When Electron apps launch from Finder/Explorer, the PATH is minimal. This skill covers detecting and using CLI tools reliably.

## The PATH Problem

When launched from terminal:
```
PATH=/usr/local/bin:/usr/bin:/bin:/opt/homebrew/bin:~/.nvm/versions/node/v20/bin:...
```

When launched from Finder (macOS):
```
PATH=/usr/bin:/bin:/usr/sbin:/sbin
```

## CLI Detector Pattern

```typescript
// electron/cli-detector.ts
import { exec } from 'child_process';
import { promisify } from 'util';
import * as fs from 'fs';
import * as path from 'path';
import * as os from 'os';

const execAsync = promisify(exec);

export interface CliStatus {
  found: boolean;
  path?: string;
  version?: string;
  error?: string;
}

// Common installation paths for various tools
function getCommonPaths(toolName: string): string[] {
  const home = os.homedir();

  return [
    // Homebrew (macOS)
    `/usr/local/bin/${toolName}`,
    `/opt/homebrew/bin/${toolName}`,

    // User-local installations
    path.join(home, '.local', 'bin', toolName),

    // Tool-specific locations
    path.join(home, '.claude', 'bin', toolName),

    // Node.js via nvm
    path.join(home, '.nvm', 'versions', 'node', 'current', 'bin', toolName),

    // System paths
    `/usr/bin/${toolName}`,

    // Windows-specific (if on Windows)
    path.join(home, 'AppData', 'Roaming', 'npm', `${toolName}.cmd`),
    `C:\\Program Files\\nodejs\\${toolName}.cmd`,
  ];
}

function isExecutable(filePath: string): boolean {
  try {
    fs.accessSync(filePath, fs.constants.X_OK);
    return true;
  } catch {
    return false;
  }
}

function findInCommonPaths(toolName: string): string | null {
  for (const toolPath of getCommonPaths(toolName)) {
    if (fs.existsSync(toolPath) && isExecutable(toolPath)) {
      return toolPath;
    }
  }
  return null;
}

export async function detectCli(toolName: string): Promise<CliStatus> {
  // First, check common installation paths
  let toolPath = findInCommonPa
