arkit-visionos-developer
Build and debug ARKit features for visionOS, including ARKitSession setup, authorization, data providers (world tracking, plane detection, scene reconstruction, hand tracking), anchor processing, and RealityKit integration. Use when implementing ARKit workflows in immersive spaces or troubleshooting ARKit data access and provider behavior on visionOS.
coding-standards-enforcer
Enforce repository coding standards for Swift 6.2 concurrency, Swift language rules, Use when reviewing or implementing Swift code changes.
ralph-driven-development-linear
Ralph Driven Development workflow that pulls Linear project issues via the Linear MCP and runs them sequentially with Codex. Use when automating task execution from a Linear project and when you need a runner that advances issues and asks for the next task automatically.
ralph-driven-development
Guide and tooling for Ralph Driven Development (RDD), a spec runner that repeatedly invokes Codex (or other agents) over ordered specs until a magic phrase signals completion. Use when setting up or operating an RDD workflow with plan.md, specs/, done.md, agent-run.log, and a ralph.py runner, or when customizing the runner CLI and prompt contract.
