Core Components​

Agent System​

The central orchestrator that manages conversation flow, tool selection, and response generation.

Key Features:

  • Streaming Responses: Real-time output with progressive enhancement
  • Context Management: Maintains conversation history and workspace context
  • Tool Orchestration: Intelligent tool selection and chaining
  • Error Handling: Robust error recovery and user feedback

Implementation:

class GrokAgent {
  private tools: ToolRegistry;
  private context: ConversationContext;
  private streaming: StreamingManager;

  async processQuery(input: string): Promise<StreamingResponse> {
    // Natural language processing
    // Tool selection and execution
    // Response generation
  }
}

Tool System​

Modular tool architecture enabling extensible functionality through standardized interfaces.

Tool Categories:

  1. Core Tools: Essential file and system operations
  2. Advanced Tools: Complex operations and AI-enhanced workflows
  3. Integration Tools: External system connectivity

Tool Interface:

interface Tool {
  name: string;
  description: string;
  schema: JSONSchema;
  execute(params: ToolParams): Promise<ToolResult>;
}

Plan Mode Engine​

Claude Code-compatible read-only exploration system with AI-powered planning.

Activation Flow:

User: Shift+Tab (twice) → Plan Mode Active
                      ↓
Read-only Tool Filter → Safe Exploration
                      ↓
AI Planning Engine → Implementation Strategy
                      ↓
User Approval → Execution Phase

Safety Features:

  • Destructive operation blocking
  • Read-only tool filtering
  • User confirmation for execution
  • Rollback capabilities

Data Flow Architecture​

Request Processing Pipeline​

User Input → Input Parser → Intent Recognition → Tool Selection → Execution → Response Generation
     ↓            ↓              ↓                 ↓           ↓            ↓
Context      Validation     AI Analysis      Tool Chain   Real-time    Streaming
Loading      & Sanitization                  Planning     Feedback     Output

Context Management​

Session Context:

  • Conversation history
  • File system state
  • Tool execution results
  • User preferences

Workspace Context:

  • Project structure
  • Git repository state
  • Configuration files
  • Environment variables

Global Context:

  • User settings
  • MCP server configurations
  • Tool availability

Performance Architecture​

Streaming System​

Real-time Response Delivery:

  • Progressive content rendering
  • Chunked data transmission
  • Background processing
  • Adaptive buffering

Implementation Pattern:

async function* streamResponse(query: string) {
  yield { type: "thinking", content: "Processing..." };

  for await (const result of processTools(query)) {
    yield { type: "tool_result", content: result };
  }

  yield { type: "response", content: finalResponse };
}

Caching Strategy​

Multi-Level Caching:

  • L1: In-memory tool results
  • L2: Session-based context
  • L3: Persistent user data
  • L4: MCP server responses

Memory Management​
