# 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.

Browsing & Searching Skills

Web App (local)

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

CLI search with grep

# 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/

Troubleshooting

Skills not recognized by my agent

# 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

# 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

# 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

# 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")
