We built this library because agent harnesses were too fragmented and we needed a simple abstraction to call multiple coding-agent SDKs.lite-harness has one function - query()import { query } from @lite-harness/sdk ;for await (const message of query({ prompt: Fix the failing test , options: { // swap harness between: claude-agent , openai-agents , pi-ai harness: openai-agents , model: gpt-5.5 , }, })) { console.log(message); }
