Manages project plans with tim. Use whenever the user mentions tim, asks to "generate plan 123" (or any number), "work on plan 123", or when you are working on a tim task.
Guidance on writing fast, robust, modern Svelte code. Load this skill whenever in a Svelte project and asked to write/edit or analyze a Svelte component or module. Covers reactivity, event handling, styling, integration with libraries and more.
Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.
Audit and improve SwiftUI runtime performance from code review and architecture. Use for requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is insufficient.
Refactor and review SwiftUI view files for consistent structure, dependency injection, and Observation usage. Use when asked to clean up a SwiftUI view’s layout/ordering, handle view models safely (non-optional when possible), or standardize how dependencies and @Observable state are initialized and passed.

Review and fix Swift Concurrency issues in Swift 6.2+ codebases by applying actor isolation, Sendable safety, and modern concurrency patterns with minimal behavior changes.
@MainActor, actor, nonisolated) and whether a default actor isolation mode is enabled.Prefer edits that preserve existing behavior while satisfying data-race safety.
Common fixes:
@MainActor.extension Foo: @MainActor SomeProtocol).@MainActor or move into an actor.@concurrent async function on a nonisolated type or use an actor to guard mutable state.Sendable conformance only when correct; avoid @unchecked Sendable unless you can prove thread safety.references/swift-6-2-concurrency.md for Swift 6.2 changes, patterns, and examples.references/swiftui-concurrency-tour-wwdc.md for SwiftUI-specific concurrency guidance.
