## 🛠️ Available Tools

### 🆕 1. Ask UTCP Expert (LLM Agent)

**NEW!** Ask an OpenAI-powered agent any question about UTCP:

```typescript
{
  "tool": "ask_utcp_expert",
  "arguments": {
    "question": "How do I authenticate with bearer tokens?"
  }
}
```

**The agent:**
- Has deep knowledge of the entire UTCP specification
- Retrieves relevant documentation automatically
- Provides detailed explanations with code examples
- Includes source references
- Offers best practices and guidance

**Example Questions:**
- "What is body_template and when should I use it?"
- "Show me a complete HTTP tool example with OAuth2"
- "How do I chain CLI commands together?"
- "Why is my tool name failing validation?"

**Requires:** OpenAI API key (set `OPENAI_API_KEY` environment variable)

---

### 2. Search UTCP Documentation

Search the complete UTCP specification:

```typescript
{
  "tool": "search_utcp_docs",
  "arguments": {
    "query": "how to implement HTTP authentication",
    "section": "protocols",  // optional: introduction, protocols, guides, api
    "limit": 5               // optional: max results
  }
}
```

**Example Response:**
```
# Search Results for "HTTP authentication"

## Result 1: HTTP Protocol Authentication
**Section:** protocols
**Relevance:** 45

Authentication in HTTP protocols can be configured using the auth field...
```

### 3. Validate UTCP Manual

Validate your UTCP manual against the specification:

```typescript
{
  "tool": "validate_utcp_manual",
  "arguments": {
    "manual": {
      "manual_version": "1.0.0",
      "utcp_version": "1.0.1",
      "tools": [...]
    }
  }
}
```

**Response:**
```
✅ Valid UTCP Manual
The manual passes all validation checks and conforms to UTCP v1.0.1 specification.
```

Or with errors:
```
❌ Invalid UTCP Manual

## Errors
- /tools/0/name: Tool name "GetWeather" must use snake_case
- /tools/0/tool_call_template: HTTP template requires a URL

## Warnings
- /tools/0/description: Tool description should be at least 10 characters
```

### 4. Generate UTCP Manual

Generate a UTCP manual template:

```typescript
{
  "tool": "generate_utcp_manual",
  "arguments": {
    "tool_name": "get_weather",
    "description": "Get current weather for a location",
    "protocol": "http",
    "endpoint": "https://api.openweathermap.org/data/2.5/weather",
    "method": "GET",
    "parameters": {
      "location": {
        "type": "string",
        "description": "City name",
        "required": true
      }
    },
    "include_auth": true
  }
}
```

**Supported Protocols:**
- `http` - RESTful HTTP APIs
- `cli` - Command-line tools
- `mcp` - Model Context Protocol servers
- `sse` - Server-Sent Events
- `streamable_http` - Streaming HTTP responses

### 5. Convert OpenAPI to UTCP

```typescript
{
  "tool": "convert_openapi_to_utcp",
  "arguments": {
    "openapi_spec": {
      "openapi": "3.0.0",
      "info": { "title": "My API", "version": "1.0.0" },

// 1. Generate a template
const result = await callTool("generate_utcp_manual", {
  tool_name: "send_email",
  description: "Send an email via SendGrid API",
  protocol: "http",
  endpoint: "https://api.sendgrid.com/v3/mail/send",
  method: "POST",
  parameters: {
    to: { type: "string", description: "Recipient email", required: true },
    subject: { type: "string", description: "Email subject", required: true },
    body: { type: "string", description: "Email body", required: true }
  },
  include_auth: true
});

// 2. Validate the generated manual
const validation = await callTool("validate_utcp_manual", {
  manual: JSON.parse(result)
});

// 3. Get best practices for authentication
const practices = await callTool("get_best_practices", {
  topic: "authentication"
});
```

### Example 2: Converting Existing OpenAPI Spec

```typescript
// 1. Read your OpenAPI spec
const openApiSpec = JSON.parse(fs.readFileSync("api-spec.json"));

// 2. Convert to UTCP
const utcpManual = await callTool("convert_openapi_to_utcp", {
  openapi_spec: openApiSpec
});

// 3. Validate the result
const validation = await callTool("validate_utcp_manual", {
  manual: JSON.parse(utcpManual)
});
```

### Example 3: Searching Documentation

```typescript
// Search for specific implementation details
const results = await callTool("search_utcp_docs", {
  query: "how to handle streaming responses",
  section: "protocols",
  limit: 3
});

// Get an example to reference
const example = await callTool("get_utcp_examples", {
  use_case: "github"
});
```

## 🐛 Troubleshooting

### Server Not Starting

**Issue:** `Error: Cannot find module 'ajv-formats'`

**Solution:**
```bash
npm install ajv-formats
npm run build
```

### Documentation Not Loading

**Issue:** `Error loading llms.txt`

**Solution:** Ensure `DOCS_PATH` environment variable points to the correct directory:
```bash
export DOCS_PATH=/path/to/utcp-docs
```
