Loading

⚡ Remote Download Architecture: Skills marked with ⚡ are not stored locally in this repo. They are downloaded from their upstream GitHub repos at install time using the interactive installer. Only original skills, composite skills, ClawHub skills, and zh-TW translations are stored in this repo.

Role-Based Presets

The installer includes 8 curated presets. Selecting a preset pre-checks the listed skills (you can still add or remove before installing). Dependencies are auto-resolved.

Installation

Interactive Installer (Recommended)

npx github:Tai-ch0802/skills-bundle

The installer guides you through:

1. 🌐 Language — English or 繁體中文
2. 🎯 Preset — Full-Stack Web, Mobile, Security, Architect, AI Builder, Content Creator, DevOps, SDD, or Custom
3. 📦 Skills — Fine-tune selection (preset pre-checks relevant skills)
4. 📂 Scope — Project directory or global (~/.gemini/antigravity/skills/)
5. 📁 Path — Preset paths for popular AI agents or custom path

Note: Most skills (⚡) require internet access and are downloaded from GitHub at install time.

Manual Installation

# Only locally-stored skills can be copied manually:
cp -r prd sa sdd refactoring /your-project/.agent/skills/

# Traditional Chinese version
cp -r i18n/zh-TW/* /your-project/.agent/skills/

For remote skills, use the interactive installer — it handles downloading automatically.

Internationalization (i18n)

Language	Directory	Status
English (default)	Root directories	✅ Complete
繁體中文 (Traditional Chinese)	i18n/zh-TW/	✅ Complete

Contributing Translations

1. Create a new directory under i18n/ (e.g., i18n/ja/ for Japanese)
2. Mirror the English skill structure and translate all files
3. Update the language table above
