Provider	Skills Path	Description
Claude Code	~/.claude/skills	Anthropic's AI coding assistant
Codex	~/.codex/skills/public	OpenAI's code generation tool

Requirements

• macOS 15+

Installation

Download (Recommended)

Download the latest release from GitHub Releases.

Build from Source

git clone https://github.com/tddworks/SkillsManager.git
cd SkillsManager
swift build -c release

Usage

Launch the app to browse available skills. The three-column layout shows:

• Sidebar - Navigate between installed skills, provider filters, and remote catalogs
• Main Content - Browse skills in grid or list view with tag-based filtering
• Detail Panel - View skill info, manage tags, install/uninstall

Adding Catalogs

1. Click "+ Add Catalog" in the sidebar footer
2. Choose GitHub Repository or Local Directory
3. Enter a URL (e.g., https://github.com/anthropics/skills) or browse for a folder
4. Click "Add Catalog"

Tagging Skills

1. Select a skill to open the detail panel
2. In the Tags section, click "+ add" to create a new tag
3. Tags are global labels - once created, they appear in the filter bar across all views
4. Purple tags come from SKILL.md frontmatter; cyan tags are your custom tags

Development

Command Line (Swift Package Manager)

# Build the project
swift build

# Run all tests
swift test

# Run the app
swift run SkillsManager

Xcode (with SwiftUI Previews)

The project uses Tuist to generate Xcode projects with SwiftUI preview support.

# Install Tuist (if not installed)
brew install tuist

# Generate Xcode project
tuist generate

# Open in Xcode
open SkillsManager.xcworkspace

# Run tests via Tuist
tuist test

Architecture

Full documentation: docs/ARCHITECTURE.md

Skills Manager uses a layered architecture with rich domain models and SwiftUI Atomic Design:

SkillLibrary (@Observable, coordinator)
├── localCatalog: SkillsCatalog     ← Installed skills (claude + codex)
├── remoteCatalogs: [SkillsCatalog] ← GitHub repos or local directories
│   └── skills: [Skill]             ← Each catalog OWNS its skills
└── skillTags: SkillTags            ← Global tag management aggregate

Layer	Location	Purpose
Domain	Sources/Domain/	Rich models (Skill, SkillsCatalog, SkillTags), protocols
Infrastructure	Sources/Infrastructure/	Repositories, parsers, persistence
App	Sources/App/	SwiftUI views (Atomic Design), coordinator, design tokens

Key Design Decisions

• Rich Domain Models - Behavior encapsulated in models (not anemic data)
• Domain Aggregates - SkillTags is an @Observable aggregate managing the tags feature
• Tell-Don't-Ask - Objects manage their own state; callers tell objects what to do
• Protocol-Based DI - @Mockable protocols for testability
• Chicago School TDD - Test state changes, not interactions
• No ViewModel Layer - Views consume domain models directly
• SwiftUI Atomic Design - Atoms, Molecules, Organisms, Pages
• Design Tokens - DS enum mirrors prototype CSS for consistent dark theme

Release & Auto-Updates

The project includes CI/CD workflows and Sparkle integration for automatic updates.

Setup Sparkle Keys

Generate EdDSA keys for signing updates:

# Build first to get Sparkle tools
swift build

# Generate key pair
./scripts/sparkle-setup.sh

Required GitHub Secrets

Secret	Purpose
APPLE_CERTIFICATE_P12	Base64-encoded Developer ID certificate
APPLE_CERTIFICATE_PASSWORD	Certificate password
APP_STORE_CONNECT_API_KEY_P8	Base64-encoded App Store Connect API key
APP_STORE_CONNECT_KEY_ID	API key ID

Creating a Release

Releases are triggered by:

• Pushing a version tag: git tag v1.0.0 && git push --tags
• Manual workflow dispatch with version input

The release workflow will:

1. Build universal binary (arm64 + x86_64)
2. Sign with Developer ID
3. Notarize with Apple
4. Create DMG and ZIP artifacts
5. Publish GitHub Release
6. Update Sparkle appcast for auto-updates
