## Key Rig Features Relevant to QwenClaw

### 1. **Advanced Tool Calling System**

#### Current QwenClaw
- Basic skill system with static prompts
- No dynamic tool resolution
- Limited tool orchestration

#### Rig's Approach
```rust
// Static tools - always available
.tool(calculator)
.tool(web_search)

// Dynamic tools - context-dependent
.dynamic_tools(2, tool_index, toolset)
```

**Benefits for QwenClaw**:
- **Dynamic Tool Resolution**: Tools fetched from vector store based on context
- **ToolSet Management**: Centralized tool registry with name→function mapping
- **Multi-Turn Tool Calls**: Support for chained tool invocations
- **Error Handling**: Built-in error states and recovery

---

### 2. **Multi-Agent Orchestration**

#### Current QwenClaw
- Single agent per session
- No agent-to-agent communication
- Limited agent composition

#### Rig's Capabilities
- **Agent Council Pattern**: Multiple specialized agents collaborating
- **Static vs Dynamic Context**: Per-agent knowledge bases
- **Prompt Hooks**: Observability and custom behavior injection
- **Multi-Turn Support**: Configurable conversation depth

**Integration Opportunity**:
```rust
// QwenClaw could support:
let research_agent = qwen.agent("researcher")
    .preamble("You are a research specialist.")
    .dynamic_context(5, research_docs)
    .tool(academic_search)
    .build();

let writing_agent = qwen.agent("writer")
    .preamble("You are a content writer.")
    .tool(grammar_check)
    .tool(style_enhance)
    .build();

// Orchestrate both agents
let council = AgentCouncil::new()
    .add_agent(research_agent)
    .add_agent(writing_agent)
    .build();
```

---

### 3. **RAG (Retrieval-Augmented Generation)**

#### Current QwenClaw
- No native vector store integration
- Skills are static files
- No semantic search capabilities

#### Rig's RAG System
```rust
let rag_agent = client.agent("gpt-4")
    .preamble("You are a knowledge base assistant.")
    .dynamic_context(5, document_store)  // Fetch 5 relevant docs
    .temperature(0.3)
    .build();
```

**Vector Store Integrations** (10+ supported):
- MongoDB (`rig-mongodb`)
- LanceDB (`rig-lancedb`)
- Qdrant (`rig-qdrant`)
- SQLite (`rig-sqlite`)
- SurrealDB (`rig-surrealdb`)
- Milvus (`rig-milvus`)
- ScyllaDB (`rig-scylladb`)
- AWS S3 Vectors (`rig-s3vectors`)
- Neo4j (`rig-neo4j`)
- HelixDB (`rig-helixdb`)

**Benefits for QwenClaw**:
- **Semantic Skill Discovery**: Find relevant skills via vector search
- **Dynamic Knowledge Base**: Load context from vector stores
- **Persistent Memory**: Long-term agent memory via embeddings
- **Cross-Skill Search**: Search across all skill documentation

---

### 4. **Multi-Provider Support**

#### Current QwenClaw
- Single Qwen model provider
- Manual provider switching

#### Rig's Unified Interface
```rust
// Switch providers seamlessly
let openai_client = rig::providers::openai::Client::from_env();
let anthropic_client = rig::providers::anthropic::Client::from_env();
let ollama_client = rig::providers::ollama::Client::from_env();

// Same API across all providers
let agent = client.agent("model-name")
    .preamble("...")
    .build();
```

**Supported Providers** (20+):
- OpenAI, Anthropic, Google Vertex AI
- Ollama, Cohere, Hugging Face
- AWS Bedrock, Azure OpenAI
- And 13+ more

**Benefits for QwenClaw**:
- **Provider Fallback**: Auto-failover between providers
- **Cost Optimization**: Route to cheapest available provider
- **Model Diversity**: Access specialized models per task
- **No Vendor Lock-in**: Easy provider switching

---

### 5. **Streaming & Multi-Turn Conversations**

#### Current QwenClaw
- Basic request/response
- Limited conversation management

#### Rig's Streaming Support
```rust
let response = agent.prompt("Hello")
    .multi_turn(3)  // Allow 3 rounds of tool calls
    .stream()       // Stream tokens
    .await?;
```

**Benefits**:
- **Real-time Responses**: Token-by-token streaming
- **Complex Workflows**: Multi-step tool orchestration
- **Conversation Memory**: Built-in session management

---

┌─────────────────┐     ┌─────────────────┐
│  QwenClaw       │────▶│  Rig Service    │
│  (TypeScript)   │◀────│  (Rust)         │
│  - Daemon       │     │  - Tool Calling │
│  - Web UI       │     │  - RAG          │
│  - Scheduling   │     │  - Multi-Agent  │
└─────────────────┘     └─────────────────┘
         │                       │
         ▼                       ▼
    Qwen Code            Vector Stores
    Telegram             Model Providers
```

**Communication**:

## Specific Implementation Recommendations

### 1. **Add Vector Store Support**

```typescript
// New QwenClaw feature inspired by Rig
import { QdrantClient } from '@qdrant/js-client-rest';

class SkillVectorStore {
  private client: QdrantClient;
  
  async searchRelevantSkills(query: string, limit: number = 3) {
    // Semantic search for relevant skills
    const results = await this.client.search({
      collection_name: 'qwenclaw-skills',
      vector: await this.embed(query),
      limit,
    });
    return results.map(r => r.payload.skill);
  }
  
  async indexSkill(skill: Skill) {
    await this.client.upsert({
      collection_name: 'qwenclaw-skills',
      points: [{
        id: skill.name,
        vector: await this.embed(skill.description),
        payload: skill,
      }],
    });
  }
}
```

### 2. **Implement ToolSet Pattern**

```typescript
// Tool registry inspired by Rig
class ToolSet {
  private tools: Map<string, Tool> = new Map();
  
  register(tool: Tool) {
    this.tools.set(tool.name, tool);
  }
  
  async execute(name: string, args: any): Promise<any> {
    const tool = this.tools.get(name);
    if (!tool) throw new Error(`Tool ${name} not found`);
    return await tool.execute(args);
  }
  
  getStaticTools(): Tool[] {
    return Array.from(this.tools.values());
  }
  
  async getDynamicTools(query: string, limit: number): Promise<Tool[]> {
    // Vector-based tool discovery
    const relevant = await this.vectorStore.search(query, limit);
    return relevant.map(r => this.tools.get(r.name)).filter(Boolean);
  }
}
```

### 3. **Create Agent Council**

```typescript
// Multi-agent orchestration
class AgentCouncil {
  private agents: Map<string, Agent> = new Map();
  
  addAgent(agent: Agent) {
    this.agents.set(agent.name, agent);
  }
  
  async orchestrate(task: string): Promise<string> {
    // Determine which agents should handle the task
    const relevantAgents = await this.selectAgents(task);
    
    // Coordinate between agents
    const results = await Promise.all(
      relevantAgents.map(agent => agent.execute(task))
    );
    
    // Synthesize results
    return this.synthesize(results);
  }
}
```

## Code Comparison: Current vs Rig-Inspired

### Current QwenClaw Skill Usage
```typescript
// Static skill loading
const skill = await loadSkill('content-research-writer');
const result = await qwen.prompt(`${skill.prompt}\n\nTask: ${task}`);
```

### Rig-Inspired QwenClaw
```typescript
// Dynamic skill discovery + execution
const agent = qwenclaw.agent('researcher')
  .preamble('You are a research specialist.')
  .dynamic_tools(3, await vectorStore.search('research'))
  .tool(academicSearch)
  .tool(citationManager)
  .temperature(0.3)
  .build();

const result = await agent.prompt(task)
  .multi_turn(2)
  .stream();
```
