agent-sdk

The Claude Agent SDK skill provides comprehensive expertise in Anthropic's official agent development framework. It is designed for engineers and developers looking to transition from simple API requests to robust, production-grade autonomous agent systems. The skill covers the full lifecycle of agent development, including the agent loop, context management, tool orchestration, and system prompt engineering. By utilizing this skill, developers can effectively implement complex agentic workflows, such as multi-step reasoning chains, tool-use loops, and subagent hierarchies. It specifically supports integration with Model Context Protocol (MCP) servers, enabling agents to interface with external filesystems, databases, and third-party APIs in a standardized manner.

• Architecture guidance for autonomous agent loops and state management.

• Tool design and implementation using JSON schemas for seamless model interaction.

• Advanced context management including automatic compaction, token budget tracking, and conversation history isolation via subagents.

• Integration with the Model Context Protocol (MCP) for extensible tool capabilities and environment connectivity.

• Implementation of production patterns like hooks, permission systems (whitelists/blacklists), and error-handling retries.

• Support for both Python (claude-agents) and TypeScript (@anthropics/agent-sdk) implementations.

• Recommended for autonomous agents that require iterative tool execution and verification.

• Use for agentic workflows involving task decomposition and multi-agent collaboration.

• Not suitable for simple single-turn chat applications or use cases where direct interaction with the Messages API is sufficient.

• Ensure environment variables like ANTHROPIC_API_KEY are configured appropriately for secure access.

• Follow best practices for token usage by monitoring tool output and utilizing context summarization features.

• Leverage subagents for security-sensitive operations or modular task isolation to prevent context pollution.
