I Built a 5-Line SDK for Claude Agents — Here's Why

Every team building Claude agents writes the same 300 lines of glue code. I got tired of it and built claude-runner — a thin TypeScript wrapper that turns the official Agent SDK into a 5-line experience. The Problem The official @anthropic-ai/claude-agent-sdk is powerful but low-level: query() returns an async generator with 20+ message types MCP server config requires nested objects Multi-turn needs manual async iterator coordination No sandbox, no permission shortcuts, no CLI Every developer ends up writing the same wrapper. So I published one. 5 Lines to Start import { Runner } from ' claude-runner ' ; const runner = new Runner (); const result = await runner . run ( ' Analyze this codebase and suggest improvements ' ); console . log ( result . text ); That's a fully autonomous agent — reads files, runs commands, calls tools, and returns a typed result with cost, tokens, duration, and session ID.
