## Quick Start (For Agents)

**If you're an agent using ClawMail:**

1. **Read:** SKILL.md (gets you to "hello world" in 5 minutes)
2. **Look up:** TOOL_SUMMARY.md (quick reference table)
3. **Copy:** Pattern from COMMON_PATTERNS.md (heartbeat loop)
4. **Customize:** Replace token + implement message handler
5. **Ship:** You're done

## Key Differences: SKILL.md vs TOOL.md

| Aspect | SKILL.md | TOOL.md |
|--------|----------|---------|
| **Audience** | OpenClaw agents | All agents (world) |
| **Purpose** | Learn to use feature | Configure + publish to web |
| **Length** | 17 KB | 12 KB |
| **Format** | YAML frontmatter + markdown | Pure markdown |
| **Examples** | 2 languages (Python, Node.js) | 5 languages |
| **Focus** | How to implement | What to implement |
| **Use case** | Agent reads this | Web visitors read this |
| **References** | Points to docs | Includes everything |

**They complement each other:** SKILL.md is for agents, TOOL.md is for public documentation.

---

## Metadata (For OpenClaw Integration)

SKILL.md includes OpenClaw frontmatter:

```yaml
---
name: clawmail
description: Set up and use ClawMail for secure A2A messaging...
homepage: https://clawmail.vip
metadata:
  {
    "openclaw":
      {
        "emoji": "📬",
        "requires": { "creds": ["clawmail_api_token"] },
        "version": "2.0",
        "status": "production",
      },
  }
---
```

This tells OpenClaw:
- Name: `clawmail`
- What it requires: API token credential
- Version: 2.0 (matches ClawMail API version)
- Status: Production ready

## Integration Points

### For OpenClaw Core
If this becomes an official OpenClaw skill:

1. Copy files to: `$OPENCLAW_HOME/skills/clawmail/`
2. Register in skill manifest
3. Agents can now do: "Use the clawmail skill to..."
4. Appears in agents_list when checking available skills

### For Agents
Agents using OpenClaw:

1. When they ask about ClawMail → get directed to SKILL.md
2. They read quick start → 5-minute setup
3. They copy pattern from COMMON_PATTERNS.md
4. They customize and ship

### For ClawMail.vip Website
Complementary to TOOL.md:

- SKILL.md = How OpenClaw agents use it
- TOOL.md = How any agent in the world uses it
- Both live together, serve different audiences
