Claude Agent SDK Integration
Claude Agent SDK — an earlier version of Anthropic's official SDK for building agents based on Claude models (supplement to id=177). Current recommended SDK uses native anthropic Python client with tool_use support, and for complex agentic systems — integration with LangGraph or OpenAI Agents SDK.
Direct Integration via Anthropic API
Tool definitions in Anthropic format. Agent loop with tool calling. Handles parallel tool calls, streaming, computer use (beta). Simple setup for 3–5 tools without external frameworks.
Key Features:
- Tool use with Anthropic native format
- Parallel tool execution
- Streaming responses
- Computer use support (beta)
- Agentic loop implementation
Practical Case Study: Corporate Portal AI Assistant
Task: Add AI assistant to corporate portal (Python/FastAPI) without external frameworks.
Tools:
- search_knowledge_base (vector search)
- get_employee_info (HR directory)
- create_it_ticket (ServiceDesk)
- get_meeting_rooms (room booking)
- get_company_policies (regulatory docs)
Results:
- Implementation time: 2 weeks (vs 4 weeks estimate with LangChain)
- Codebase: 450 lines vs 900 with LangChain PoC
- First token latency: 80ms lower (no LangChain overhead)
Timeline
- Basic agent with 3–5 tools: 3–5 days
- Streaming + error handling: 3–5 days
- Computer Use integration: 1–2 weeks
- Web app integration: 1 week
