## What Are Claude Code Skills & Agent Plugins?

Claude Code skills (also called agent skills or coding agent plugins) are modular instruction packages that give AI coding agents domain expertise they don't have out of the box. Each skill includes:

- **SKILL.md** — structured instructions, workflows, and decision frameworks
- **Python tools** — 305 CLI scripts (all stdlib-only, zero pip installs)
- **Reference docs** — templates, checklists, and domain-specific knowledge

**One repo, eleven platforms.** Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, and converts to 8 more tools via `scripts/convert.sh`. All 305 Python tools run anywhere Python runs.

### Skills vs Agents vs Personas

| | Skills | Agents | Personas |
|---|---|---|---|
| **Purpose** | How to execute a task | What task to do | Who is thinking |
| **Scope** | Single domain | Single domain | Cross-domain |
| **Voice** | Neutral | Professional | Personality-driven |
| **Example** | "Follow these steps for SEO" | "Run a security audit" | "Think like a startup CTO" |

All three work together. See [Orchestration](#orchestration) for how to combine them.

## Multi-Tool Support (New)

**Convert all 156 skills to 7 AI coding tools** with a single script:

| Tool | Format | Install |
|------|--------|---------|
| **Cursor** | `.mdc` rules | `./scripts/install.sh --tool cursor --target .` |
| **Aider** | `CONVENTIONS.md` | `./scripts/install.sh --tool aider --target .` |
| **Kilo Code** | `.kilocode/rules/` | `./scripts/install.sh --tool kilocode --target .` |
| **Windsurf** | `.windsurf/skills/` | `./scripts/install.sh --tool windsurf --target .` |
| **OpenCode** | `.opencode/skills/` | `./scripts/install.sh --tool opencode --target .` |
| **Augment** | `.augment/rules/` | `./scripts/install.sh --tool augment --target .` |
| **Antigravity** | `~/.gemini/antigravity/skills/` | `./scripts/install.sh --tool antigravity` |
| **Hermes Agent** | `~/.hermes/skills/` | `python scripts/sync-hermes-skills.py --verbose` |

**How it works:**

```bash
# 1. Convert all skills to all tools (takes ~15 seconds)
./scripts/convert.sh --tool all

# 2. Install into your project (with confirmation)
./scripts/install.sh --tool cursor --target /path/to/project

# Or use --force to skip confirmation:
./scripts/install.sh --tool aider --target . --force

# 3. Verify
find .cursor/rules -name "*.mdc" | wc -l  # Should show 156
```

**Each tool gets:**
- ✅ All 156 skills converted to native format
- ✅ Per-tool README with install/verify/update steps
- ✅ Support for scripts, references, templates where applicable
- ✅ Zero manual conversion work

Run `./scripts/convert.sh --tool all` to generate tool-specific outputs locally.

## Personas

Pre-configured agent identities with curated skill loadouts, workflows, and distinct communication styles. Personas go beyond "use these skills" — they define how an agent thinks, prioritizes, and communicates.

| Persona | Domain | Best For |
|---------|--------|----------|
| [**Startup CTO**](agents/personas/startup-cto.md) | Engineering + Strategy | Architecture decisions, tech stack selection, team building, technical due diligence |
| [**Growth Marketer**](agents/personas/growth-marketer.md) | Marketing + Growth | Content-led growth, launch strategy, channel optimization, bootstrapped marketing |
| [**Solo Founder**](agents/personas/solo-founder.md) | Cross-domain | One-person startups, side projects, MVP building, wearing all hats |

**Usage:**
```bash
# Claude Code
cp agents/personas/startup-cto.md ~/.claude/agents/

# Any tool
./scripts/convert.sh --tool cursor  # Converts personas too
```

See [agents/personas/](agents/personas/) for details. Create your own with [TEMPLATE.md](agents/personas/TEMPLATE.md).

## Orchestration

A lightweight protocol for coordinating personas, skills, and agents on work that crosses domain boundaries. No framework required.

**Four patterns:**

| Pattern | What | When |
|---------|------|------|
| **Solo Sprint** | Switch personas across project phases | Side projects, MVPs, solo founders |
| **Domain Deep-Dive** | One persona + multiple stacked skills | Architecture reviews, compliance audits |
| **Mu
