Root cause: On macOS, GUI applications don't inherit shell profile modifications (.zshrc, .bashrc). When OpenWork spawns the opencode engine, the PATH doesn't include paths like
/opt/homebrew/bin where Homebrew-installed tools like npx reside.
The fix (packages/desktop/src-tauri/src/paths.rs): Added a common_tool_paths() function that returns typical locations where user-installed tools are found:
- macOS: /opt/homebrew/bin, /usr/local/bin, ~/.nvm/current/bin, ~/.volta/bin, ~/.bun/bin, ~/.cargo/bin, etc.
- Linux: Similar paths adapted for Linux conventions
- Windows: volta, pnpm, cargo, npm global paths
These paths are now prepended to the PATH environment variable when spawning processes.
To test the fix: Build and run the app, then try enabling your Playwright MCP server - it should now find npx correctly without needing to specify the full path.
