Skills Public

A collection of reusable development skills for Apple platforms, GitHub workflows, React performance work, and skill curation.

Overview

This repository contains focused, self-contained skills that help with recurring engineering tasks such as generating App Store release notes, debugging iOS apps, improving SwiftUI and React code, packaging macOS apps, and auditing what new skills a project actually needs.

Skills

This repo currently includes 11 skills:

Skill	Folder	Description
App Store Changelog	app-store-changelog	Creates user-facing App Store release notes from git history by collecting changes since the last tag, filtering for user-visible work, and rewriting it into concise "What's New" bullets.
GitHub	github	Uses the gh CLI to inspect and operate on GitHub issues, pull requests, workflow runs, and API data, including CI checks, run logs, and advanced queries.
iOS Debugger Agent	ios-debugger-agent	Uses XcodeBuildMCP to build, launch, and debug the current iOS app on a booted simulator, including UI inspection, interaction, screenshots, and log capture.
macOS SwiftPM App Packaging (No Xcode)	macos-spm-app-packaging	Scaffolds, builds, packages, signs, and optionally notarizes SwiftPM-based macOS apps without requiring an Xcode project.
Project Skill Audit	project-skill-audit	Analyzes a project's past Codex sessions, memory, existing local skills, and conventions to recommend the highest-value new skills or updates to existing ones.
React Component Performance	react-component-performance	Diagnoses slow React components by finding re-render churn, expensive render work, unstable props, and list bottlenecks, then suggests targeted optimizations and validation steps.
Swift Concurrency Expert	swift-concurrency-expert	Reviews and fixes Swift 6.2+ concurrency issues such as actor isolation problems, Sendable violations, main-actor annotations, and data-race diagnostics.
SwiftUI Liquid Glass	swiftui-liquid-glass	Implements, reviews, or refactors SwiftUI features to use the iOS 26+ Liquid Glass APIs correctly, with proper modifier ordering, grouping, interactivity, and fallbacks.
SwiftUI Performance Audit	swiftui-performance-audit	Audits SwiftUI runtime performance from code and architecture, focusing on invalidation storms, identity churn, layout thrash, heavy render work, and profiling guidance.
SwiftUI UI Patterns	swiftui-ui-patterns	Provides best practices and example-driven guidance for building SwiftUI screens and components, including navigation, sheets, app wiring, async state, and reusable UI patterns.
SwiftUI View Refactor	swiftui-view-refactor	Refactors SwiftUI view files toward smaller subviews, MV-style data flow, stable view trees, explicit dependency injection, and correct Observation usage.

Usage

Each skill is self-contained. Refer to the SKILL.md file in each skill directory for triggers, workflow guidance, examples, and supporting references.

Contributing

Skills are designed to be focused and reusable. When adding new skills, ensure they:

• Have a clear, single purpose
• Include comprehensive documentation
• Follow consistent patterns with existing skills
• Include reference materials when applicable
