Skills

Deep, single-topic capabilities. Load the relevant skill into your agent's context for focused, expert implementation guidance. Each file follows the same structure: Overview · Use Cases · Best Practices · Anti-Patterns · Checklist · Code Examples · Common Interview Questions · AI Implementation Notes.

Platform layout. Skills are split by platform inside each topic — <topic>/ios/, <topic>/android/, <topic>/flutter/, … — and each file declares platform: in its front-matter. Load only the platform you're working on. The links below are the iOS set; porting a skill? Add it in the sibling platform folder and cross-link its iOS counterpart (see CONTRIBUTING.md).
