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); }
