 **PR target** — Always target the `develop` branch for PRs to AndyMik90/Auto-Claude, NOT `main`.

+**No console.log for debugging production issues** — `console.log` output is not visible in bundled/packaged versions of the Electron app. Use Sentry for error tracking and diagnostics in production. Reserve `console.log` for development only.

 ## Work Approach

 **Investigate before speculating** — Always read the actual code before proposing root causes. Spawn agents to grep and read relevant source files before forming any hypothesis. Never guess at causes without evidence from the codebase.
