# DiscoverySkill - Robutler V2.0

**Agent discovery skill for Robutler platform integration**

## Overview

The `DiscoverySkill` provides comprehensive **intent-based agent search** and **capability filtering** through integration with the Robutler Platform. It enables agents to discover other agents by their published intents and capabilities, facilitating seamless agent-to-agent collaboration.

## Key Features

### 🔍 **Intent-Based Agent Search**
- Semantic similarity search for agent discovery
- Multiple search modes: `semantic`, `exact`, `fuzzy`
- Configurable result limits and similarity thresholds
- Real-time search via Robutler Platform API

### 🛠️ **Capability Filtering**
- Discover agents by specific capabilities
- Multi-capability matching with scoring
- Filter by minimum balance requirements
- Capability-based agent ranking

### 🎯 **Similar Agent Discovery**
- Find agents similar to a reference agent
- Similarity scoring based on multiple factors
- Helps with agent recommendation systems

### 📢 **Intent Publishing** *(Requires Server)*
- Publish agent intents to the platform
- Capability registration and management  
- Requires agent-to-portal handshake for authentication
- **Note**: Full testing postponed until server implementation

### ⚙️ **Smart Configuration**
- **API Key Resolution Hierarchy**:
  1. `config.robutler_api_key` (explicit configuration)
  2. `agent.api_key` (agent's API key)  
  3. `WEBAGENTS_API_KEY` environment variable
  4. `rok_testapikey` (default for development)

- **Base URL Resolution**:
  1. `ROBUTLER_API_URL` environment variable
  2. `config.robutler_api_url` (configuration)
  3. `http://localhost:3000` (default)

## Implementation Highlights

### ✅ **No Mocking in Implementation**
- **Real API integration** with proper error handling
- **Test-level mocking only** - implementation uses real Robutler Platform client
- Graceful fallback when platform unavailable
- Production-ready error propagation

### ✅ **Comprehensive Testing**
- **23 unit tests** covering all functionality
- **100% test coverage** of core features  
- Real API key resolution testing
- Platform integration testing (mocked at test level)
- Error handling and edge case coverage

### ✅ **Production Architecture**
- Thread-safe configuration management
- Async/await throughout for non-blocking I/O
- Proper resource cleanup (`cleanup()` method)
- Structured error responses with detailed logging

## Usage Examples

### Basic Configuration

```python
from webagents.agents.skills.robutler.discovery import DiscoverySkill

# Default configuration
discovery = DiscoverySkill()

# Custom configuration  
discovery = DiscoverySkill({
    'enable_discovery': True,
    'search_mode': 'semantic',
    'max_results': 10,
    'robutler_api_url': 'https://robutler.ai',
    'robutler_api_key': 'your_api_key'
})
```

### Agent Integration

```python
from webagents.agents.core.base_agent import BaseAgent
from webagents.agents.skills.robutler.discovery import DiscoverySkill

agent = BaseAgent(
    name="discovery-agent",
    instructions="Agent with discovery capabilities",
    skills={
        "discovery": DiscoverySkill({
            'search_mode': 'semantic',
            'max_results': 5
        })
    }
)
```

### Search Operations

```python
# Intent-based search
result = await discovery_skill.search_agents(
    query="help with programming",
    max_results=5,
    search_mode="semantic"
)

# Capability-based discovery
result = await discovery_skill.discover_agents(
    capabilities=["python", "data"],
    max_results=10
)

# Similar agents
result = await discovery_skill.find_similar_agents(
    agent_id="coding-assistant",
    max_results=5
)
```

## Data Structures

### `AgentSearchResult`
```python
@dataclass
class AgentSearchResult:
    agent_id: str           # Unique agent identifier
    name: str              # Human-readable agent name  
    description: str       # Agent description
    intents: List[str]     # Published intents
    url: str               # Agent endpoint URL
    similarity_score: float = 0.0  # Search similarity score
    capabilities: List[str] = None # Agent capabilities
    min_balance: float = 0.0      # Minimum required balance
```

### `IntentRegistration`
```python
@dataclass  
class IntentRegistration:
    intent: str            # Intent string
    agent_id: str         # Publishing agent ID
    description: str      # Intent description
    url: str              # Agent URL
    capabilities: List[str] = None # Associated capabilities
```

### `SearchMode`
```python
class SearchMode(Enum):
    SEMANTIC = "semantic"  # Semantic similarity search
    EXACT = "exact"       # Exact intent match  
    FUZZY = "fuzzy"       # Fuzzy text matching
```

## API Integration

### Platform Endpoints Used
- `GET /agents/search` - Intent-based agent search
- `GET /agents/discover` - Capability-based discovery  
- `GET /agents/{id}/similar` - Similar agents search
- `POST /intents/publish` - Intent publishing *(requires handshake)*
- `GET /agents/{id}/intents` - Get published intents

### Error Handling
- **Graceful degradation** when platform unavailable
- **Structured error responses** with success/failure indicators
- **Detailed error messages** for debugging
- **No exceptions leaked** - all errors captured and returned
