anthropic-agent-sdk

The autonomous agent loop in the Anthropic Agent SDK processes prompts, executes tools, streams messages, and aggregates results iteratively across turns. It enables agents to autonomously run multi-step tasks by continuously evaluating tool outputs to determine the next action until completion.

Tool permissions for autonomous agents are configured by explicitly defining allowed tools during SDK session initialization. This controlled tool access ensures agents only execute authorized operations, preventing unsafe SDK usage while performing multi-step workflows like reading and editing a local codebase.

Yes, the Anthropic Agent SDK supports both TypeScript and Python development scenarios requiring streaming operation. It enables developers to build autonomous agents with deterministic execution patterns, resumable sessions, and multi-step task execution across both programming languages.

Resumable sessions and cost tracking are implemented by configuring budget and turn limits during SDK session setup. This approach allows developers to manage autonomous agent execution costs while maintaining reliable session behavior for multi-step tasks with controlled tool access.

Yes, the Anthropic Agent SDK supports MCP integration, custom tools, slash commands, and plugins. These capabilities allow developers to extend autonomous agent workflows with specialized tool execution, enabling secure deployment and hosting for complex multi-step tasks.

Hooks and subagents are needed to enforce deterministic execution patterns and reliable session behavior in autonomous agent workflows. They allow developers to control tool execution, manage complex multi-step tasks, and ensure safe SDK usage by isolating specialized capabilities within the agent loop.
