Use when releasing a new plugin version, bumping versions, creating git tags, or publishing GitHub releases for this marketplace

Use when encountering Swift 6 concurrency errors, Sendable conformance warnings, actor isolation issues, "global variable is not concurrency-safe" errors, or migrating codebases to Swift 6 language mode

Use when writing or enhancing Swift documentation comments for DocC generation, adding inline doc comments to Swift source files, or when user asks for API documentation

Use when setting up DocC documentation for a Swift package, deploying to GitHub Pages, or encountering "no such module 'UIKit'" during doc generation

Use when creating demo GIFs for Swift package READMEs, recording iOS simulator videos, or setting up demo apps for SwiftUI libraries

Use when the user asks to build Android screens, Jetpack Compose layouts, Material components, or any Android app UI. Also use when styling, redesigning, or beautifying any Android interface. Covers Material 3 Expressive for Android 16, spring motion, shape variety, and platform-native patterns.

Use when the user asks to build iOS screens, SwiftUI views, UIKit layouts, mobile components, or any iOS app UI. Also use when styling, redesigning, or beautifying any iOS interface. Covers iOS 26 Liquid Glass design language, hierarchy, motion, and platform-native patterns.

Use when CLAUDE.md, AGENTS.md, or instruction files have grown too large (200+ lines, 40k+ chars), when agent performance has degraded due to bloated context, or when the user asks to restructure or clean up their instruction files

Use before editing CLAUDE.md, AGENTS.md, MEMORY.md, memory topic files, or any file under `.claude/rules/` — at any path depth, including nested subdirectory instances. Also when the user says "add this to CLAUDE.md", "remember this", "note this in the rules", or similar. Triggers on any change regardless of size and must not be skipped during multi-file edit sessions.

An example skill demonstrating the skill file format

Use when creating, modifying, or debugging Claude Code plugins. Triggers on .claude-plugin/, plugin.json, marketplace.json, commands/, agents/, skills/, hooks/ directories. Provides schemas, templates, validation workflows, and troubleshooting.

Use when adding a new TextMate grammar to the KotlinTextMate project, including corpus files, golden snapshot generation, and conformance test registration

Use when working with iOS/macOS Keychain Services (SecItem queries, kSecClass, OSStatus errors), biometric authentication (LAContext, Face ID, Touch ID), CryptoKit (AES-GCM, ChaChaPoly, ECDSA, ECDH, HPKE, ML-KEM), Secure Enclave, secure credential storage (OAuth tokens, API keys), certificate pinning (SecTrust, SPKI), keychain sharing across apps/extensions, migrating secrets from UserDefaults or plists, or OWASP MASVS/MASTG mobile compliance on Apple platforms.

Write, review, or improve UIKit code following best practices for view controller lifecycle, Auto Layout, collection views, navigation, animation, memory management, and modern iOS 18–26 APIs. Use when building new UIKit features, refactoring existing views or view controllers, reviewing code quality, adopting modern UIKit patterns (diffable data sources, compositional layout, cell configuration), or bridging UIKit with SwiftUI. Does not cover SwiftUI-only code.

Use when a new blog post draft in src/data/blog/ is ready for review before publishing — catches empty-string frontmatter bugs, unshipped draft flags, fabricated citations, heading hierarchy breaks, missing llms.txt updates, and sub-agent overreach
