## What's Inside
### 1. Antigravity Skills (`antigravity-skills/`)
50 production-grade skills organized across 10 enterprise domains. Each skill is a self-contained `SKILL.md` file with YAML frontmatter, structured prompts, and best practices -- ready to be loaded into [Antigravity](https://antigravity.ai/) or any AI coding agent.
### 2. Agent Skills Refined (`agent-skills-refined/`)
The same 50 skills in a production-ready distribution format with:
- **50 source skills** -- refined and documented versions in `skills/`
- **50 `.skill` packaged files** -- ready for direct Antigravity import in `packaged/`
- **7 comprehensive docs** -- architecture overview, usage guide, setup guide, full skill index, and more in `docs/`
### 3. Knowledge Base (`knowledge-base/`)
Curated development knowledge covering:
- Essential Claude Code plugins and community resources
- Business strategy frameworks (McKinsey / Goldman Sachs level)
- AI-first engineering workflows and prompt engineering
- Content creation automation playbooks
- 2026 startup ideas (YC-adjacent)
### 4. Curated Resources (`curated-resources/`)
Hand-picked open-source tools, plugins, skills, and extensions for:
- **Claude Code** -- plugins, skills, hooks, MCP servers, SDKs
- **Cursor** -- rules, extensions, workflows, `.cursorrules` templates
- **Antigravity** -- skills, setup guides, community resources
- **Windsurf** -- rules, extensions, `.windsurfrules` examples
- **General AI Tools** -- LLM frameworks, agent orchestration, RAG libraries, vector databases

## Quick Start
### For Antigravity
```bash
# Import a single packaged skill
antigravity skill import agent-skills-refined/packaged/code-review.skill
# Import all 50 skills at once
for f in agent-skills-refined/packaged/*.skill; do
antigravity skill import "$f"
done
```
### For Claude Code
```bash
# Copy any SKILL.md into your Claude Code skills directory
cp antigravity-skills/01-sdlc/code-review/SKILL.md ~/.claude/skills/code-review.md
# Or reference it directly in your CLAUDE.md
echo "See: antigravity-skills/01-sdlc/code-review/SKILL.md" >> CLAUDE.md
```
### For Cursor
```bash
# Use any SKILL.md as a .cursorrules file or paste into Cursor's system prompt
cp antigravity-skills/01-sdlc/code-review/SKILL.md .cursorrules
```
### For Any AI Agent
Each `SKILL.md` is a self-contained markdown prompt that works with any AI assistant. Copy the content into your agent's system prompt, skills configuration, or knowledge base.
