iOS platform-specific development with XcodeBuildMCP tools for simulator, device, UI automation, and debugging. Use when building iPhone apps, testing on simulator/device, or automating UI interactions.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Implement a feature or fix based on an issue. Use when given an issue URL to work on, or when implementing changes described in a tracked issue. Supports GitHub, Linear, and GitLab.
