# Antigravity Awesome Skills

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

**Antigravity Awesome Skills** is a curated library of 1,265+ universal agentic `SKILL.md` files that teach AI coding assistants (Claude Code, Gemini CLI, Codex CLI, Cursor, Kiro, OpenCode, AdaL, GitHub Copilot) how to perform specific tasks — deployments, security reviews, brainstorming, testing, infrastructure, and much more — consistently and reliably.

Each skill is a structured Markdown file a developer installs once, then invokes by name in any supported agent chat.

## Installation

### Recommended: npx (auto-detects tool)

```bash
# Install to default Antigravity global path (~/.gemini/antigravity/skills)
npx antigravity-awesome-skills

# Install for a specific tool
npx antigravity-awesome-skills --claude      # ~/.claude/skills/

```

### Python helper to create a skill programmatically

```python
import os
from pathlib import Path

def create_skill(name: str, description: str, triggers: list[str], body: str, install_path: str = None) -> Path:
    """
    Create a SKILL.md file and optionally install it to a skills directory.
    
    Args:
        name: kebab-case skill name
        description: one-line description
        triggers: list of natural-language trigger phrases
        body: Markdown content (headings, steps, examples)
        install_path: directory to write the file; defaults to ~/.claude/skills/
    
    Returns:
        Path to the created skill file
    """
    if install_path is None:
        install_path = Path.home() / ".claude" / "skills"
    
    skills_dir = Path(install_path)
    skills_dir.mkdir(parents=True, exist_ok=True)
    
    trigger_lines = "\n".join(f"  - {t}" for t in triggers)
    frontmatter = f"---\nname: {name}\ndescription: {description}\ntriggers:\n{trigger_lines}\n---\n\n"
    
    skill_file = skills_dir / f"{name}.md"
    skill_file.write_text(frontmatter + f"# {name.replace('-', ' ').title()}\n\n" + body)
    
    print(f"✅ Skill created: {skill_file}")
    return skill_file


# Example usage
create_skill(
    name="docker-deploy",
    description="Build and deploy a Docker container to a remote host.",
    triggers=[
        "deploy with docker",
        "build and push docker image",
        "run docker deployment",
    ],
    body="""## Steps
1. Build the image: `docker build -t $IMAGE_NAME .`
2. Tag it: `docker tag $IMAGE_NAME $REGISTRY/$IMAGE_NAME:latest`
3. Push: `docker push $REGISTRY/$IMAGE_NAME:latest`
4. SSH to host and pull: `ssh $HOST 'docker pull $REGISTRY/$IMAGE_NAME:latest && docker compose up -d'`

## Environment Variables
- `IMAGE_NAME` — name of the Docker image
- `REGISTRY` — container registry URL (e.g. ghcr.io/myorg)
- `HOST` — deployment target hostname
""",
    install_path=Path.home() / ".claude" / "skills",
)
```

## Browsing & Searching Skills

### Web App (local)

```bash
cd apps/web-app
npm install
npm run dev
# Open http://localhost:3000
```

### CLI search with grep

```bash
# Search skill names
ls ~/.gemini/antigravity/skills/ | grep "security"

# Search skill descriptions (frontmatter)
grep -l "docker" ~/.gemini/antigravity/skills/*.md

# Full-text search across all skills
grep -r "CloudFormation" ~/.gemini/antigravity/skills/
```

### Python: parse and list all installed skills

```python
import re
from pathlib import Path

def list_skills(skills_dir: str = None) -> list[dict]:
    """
    Parse all SKILL.md files in a directory and return their metadata.
    """
    if skills_dir is None:
        skills_dir = Path.home() / ".gemini" / "antigravity" / "skills"
    
    skills_dir = Path(skills_dir)
    skills = []
    
    frontmatter_pattern = re.compile(
        r"^---\s*\n(.*?)\n---", re.DOTALL
    )
    
    for skill_file in sorted(skills_dir.glob("*.md")):
        content = skill_file.read_text(encoding="utf-8")
        match = frontmatter_pattern.match(content)
        
        if match:
            fm = match.group(1)
            name_match = re.search(r"^name:\s*(.+)$", fm, re.MULTILINE)
            desc_match = re.search(r"^description:\s*(.+)$", fm, re.MULTILINE)
            skills.append({
                "file": skill_file.name,
                "name": name_match.group(1).strip() if name_match else skill_file.stem,
                "description": desc_match.group(1).strip() if desc_match else "",
            })
    
    return skills


# Print all installed skills
for skill in list_skills():
    print(f"  {skill['name']:<40} {skill['description']}")
```

### Skill validation helper (Python)

```python
import re
import sys
from pathlib import Path

REQUIRED_FRONTMATTER_KEYS = {"name", "description", "triggers"}
HIGH_RISK_PATTERNS = [
    r"curl\s+.*\|\s*bash",
    r"wget\s+.*\|\s*sh",
    r"irm\s+.*\|\s*iex",
]

def validate_skill(filepath: str) -> bool:
    content = Path(filepath).read_text(encoding="utf-8")
    
    fm_match = re.match(r"^---\s*\n(.*?)\n---", content, re.DOTALL)
    if not fm_match:
        print("❌ Missing YAML frontmatter")
        return False
    
    fm = fm_match.group(1)
    missing = []
    for key in REQUIRED_FRONTMATTER_KEYS:
        if not re.search(rf"^{key}:", fm, re.MULTILINE):
            missing.append(key)
    if missing:
        print(f"❌ Missing frontmatter keys: {missing}")
        return False
    
    warnings = []
    for pattern in HIGH_RISK_PATTERNS:
        if re.search(pattern, content, re.IGNORECASE):
            warnings.append(f"⚠️  High-risk pattern found: {pattern}")
    
    for w in warnings:
        print(w)
    
    print(f"✅ Skill valid: {filepath}")
    return True


if __name__ == "__main__":
    ok = validate_skill(sys.argv[1])
    sys.exit(0 if ok else 1)
```

## Troubleshooting

### Skills not recognized by my agent

```bash
# Confirm files exist in the right path for your tool
ls ~/.claude/skills/          # Claude Code
ls ~/.gemini/skills/          # Gemini CLI
ls .cursor/skills/            # Cursor (workspace)
ls ~/.gemini/antigravity/skills/  # Antigravity

# Re-run the installer targeting your tool explicitly
npx antigravity-awesome-skills --claude
```

### npx installer fails or hangs

```bash
# Clear npx cache and retry
npx clear-npx-cache
npx antigravity-awesome-skills

# Alternatively, clone and copy manually
git clone https://github.com/sickn33/antigravity-awesome-skills.git /tmp/aas
cp -r /tmp/aas/skills/ ~/.claude/skills/
```

### Skill invocation does nothing in Claude Code

- Ensure you use the `>> /skill-name` prefix, not `@skill-name` (that's Cursor syntax).
- Check that the skill file name matches exactly: `brainstorming.md` → `/brainstorming`.
- Restart the Claude Code session after installing new skills.

### Wrong install path on Windows

```powershell
# Windows: use $env:USERPROFILE instead of ~
$skillsPath = "$env:USERPROFILE\.claude\skills"
New-Item -ItemType Directory -Force -Path $skillsPath
npx antigravity-awesome-skills --path $skillsPath
```

### Skill file has encoding issues

```python
# Re-save a skill file as UTF-8
from pathlib import Path

skill = Path("skills/my-skill.md")
content = skill.read_bytes().decode("utf-8", errors="replace")
skill.write_text(content, encoding="utf-8")
```
