[!TIP]
Most tools will automatically discover skills in .agent/skills/. For maximum compatibility, please clone/copy into this directory.

📖 Quick Start

1. Prepare the Skills Library

First, clone this repository locally (it is recommended to place it in a fixed location for global reference):

git clone https://github.com/guanyang/antigravity-skills.git ~/antigravity-skills

2. Install Skills (Symlink Method)

We strongly recommend using Symbolic Links (Symlink) for installation, so that when you update this repository via git pull, all tools will automatically sync the latest features.

🔹 Method A: Project Level Installation

Enable skills only for the current project. Run in your project root:

mkdir -p .agent/skills
ln -s ~/antigravity-skills/skills/* .agent/skills/

🔹 Method B: Global Level Installation

Enable skills by default in all projects. Run the corresponding command based on the tool; common examples:

Tool Name	Global Installation Command (macOS/Linux)
General	`mkdir -p ~/.agent/skills && ln -s ~/antigravity-skills/skills/* ~/.agent/skills/`
Claude Code	`mkdir -p ~/.claude/skills && ln -s ~/antigravity-skills/skills/* ~/.claude/skills/`
Antigravity	`mkdir -p ~/.gemini/antigravity/skills && ln -s ~/antigravity-skills/skills/* ~/.gemini/antigravity/skills/`
Gemini	`mkdir -p ~/.gemini/skills && ln -s ~/antigravity-skills/skills/* ~/.gemini/skills/`
Codex	`mkdir -p ~/.codex/skills && ln -s ~/antigravity-skills/skills/* ~/.codex/skills/`

🔹 Method C: Claude Plugin Installation (Claude Code Only)

If you primarily use Claude Code, you can install with one click via the plugin marketplace (this method automatically handles skill loading):

# 1. Start Claude Code
# 2. Add the plugin marketplace
/plugin marketplace add guanyang/antigravity-skills

# 3. Install the plugin from the marketplace
/plugin install antigravity-skills@antigravity-skills

3. Using Skills

Enter @[skill-name] or /skill-name in the chat box to invoke them, for example:

/canvas-design Help me design a 16:9 blog cover about "Deep Learning"

4. More Information

View Manual: For detailed usage, please refer to docs/Antigravity_Skills_Manual.en.md.
Environment Dependencies: Some skills rely on Python environments; please ensure your system has necessary libraries installed (e.g., pdf2docx, pandas, etc.).

🔄 Keeping in Sync

Many skills in this project originate from excellent open-source communities. To keep in sync with upstream repositories, you can update them in the following ways:

Configuration: The skills_sources.json file in the root directory is pre-configured with the upstream repositories for major skills and usually does not need manual adjustment.
Run Sync:
You can choose to sync all skills or just a specific one:
```
# Sync all configured sources
./scripts/sync_skills.sh

# Sync only a specific source (e.g., anthropics-skills)
./scripts/sync_skills.sh anthropics-skills
```
The script will automatically pull the latest code and update the corresponding skill directories.

Note: The ui-ux-pro-max skill has a special directory structure and does not support automatic synchronization via script for now. Please use its official installation command uipro init --ai antigravity to install or update.
