gneiss

gneiss is a distributed, durable agent runtime for long-lived workflows.

The package is intended to provide the core primitives needed to run agents that:

• persist state between invocations
• survive process restarts by swapping in a durable store
• execute work across distributed workers with a shared runtime contract

Current scope

This initial release provides a small runtime surface:

• defineAgent(...) to declare an agent
• createRuntime(...) to invoke agents and persist state snapshots
• createMemoryStore() as the default storage adapter for local development

Example

const { createRuntime, defineAgent } = require("gneiss");

const counter = defineAgent({
  id: "counter",
  initialState: { count: 0 },
  async step(input, { state }) {
    const count = state.count + (input.increment ?? 1);

    return {
      output: count,
      state: { count }
    };
  }
});

async function main() {
  const runtime = createRuntime();
  const result = await runtime.invoke(counter, { increment: 2 });
  console.log(result.output); // 2
}

main().catch(console.error);

Direction

gneiss is being developed toward a fuller runtime for durable execution, stateful coordination, and distributed agent orchestration.
