Summary
If you want to run Claude Code agents in serverless functions, Docker containers, or CI/CD without spawning a CLI subprocess, this is the fix. It's a drop-in replacement for Anthropic's official SDK that runs the full agentic loop in-process. Supports custom tools, MCP servers, subagents for delegation, and third-party providers like OpenRouter. The API is nearly identical to the official SDK, so migration is straightforward. Most useful when you're deploying agents to environments where you can't rely on local binaries or need programmatic control over the execution context. Built by ara.so as part of their 2026 daily skills collection.
