Use when the user wants to watch the current GitHub repo for pull requests that need their review — new PRs, explicit review requests, re-requests after new commits — e.g. "watch for incoming reviews", "check PRs needing my review", or as the recurring body of a /loop invocation. GitHub-only (gh CLI). Not for reviewing one specific known PR (invoke pr-review directly).
AWS Lambda best practices for function design, configuration, and operations. Use when designing Lambda functions, choosing memory/timeout settings, planning concurrency and scaling, setting up monitoring, processing streams, or securing Lambda workloads. Triggers on tasks involving Lambda function creation, handler design, cold start optimization, idempotency, event source mapping, reserved/provisioned concurrency, or deciding whether Lambda is the right compute choice. Does not cover language-specific SDK patterns, CloudFormation/Terraform resource definitions, or Lambda@Edge.
Use when authoring a code review of a pull request — "review this PR", "do a code review on PR
Use when working through code-review feedback to apply fixes and replies — "address the PR comments", "reply to CodeRabbit/Codex feedback", "resolve these review threads", "apply this review". Works in two modes. Public mode (default) responds to reviewer feedback on a GitHub pull request you authored — fix, reply, resolve, commit, and push. Local mode — triggered when the request says "locally", "for myself", "apply this review", or "don't post" — applies feedback from a local review file to your working tree, posting nothing to a review platform. Each item gets a proposed fix or reply for your approval first. This is the author's side; to review someone else's PR, use pr-review.

Provides modern Jetpack Compose-first best practices covering UI patterns, app lifecycle, navigation, local storage, billing/payments, testing, And
This skill should be used when the user asks to "create a SwiftUI view", "build an iOS app", "set up an Xcode project", "review Apple platform code", "add a widget", "create a watchOS app", "build for visionOS", "fix SwiftUI layout", or when generating any Swift code targeting Apple platforms (iOS, iPadOS, macOS, tvOS, watchOS, visionOS). Provides modern SwiftUI-first best practices covering UI patterns, app lifecycle, navigation, project structure, and platform-specific guidance. Use together with `swift-development` for Swift language fundamentals. Always generates Swift unless the project explicitly requires Objective-C.

Provides modern Kotlin 2.1+ best practices covering null safety, coroutines, data modeling, error handling, idiomatic patterns, and static analysis (Detekt, ktlint). Does not cover any specific library or framework.
This skill should be used when the user asks to "write Swift code", "create a Swift type", "set up a Swift package", "review Swift code", "refactor Swift", "use async/await in Swift", "fix Swift style", or when generating any Swift source code regardless of target platform.
