@one-agent/ria-proxy

Non-invasive Re in Act plugin for OpenAI-compatible tool runtimes.

This package provides a PTC-style adapter for servers built on @mcpc-tech/aiyo. It rewrites ordinary function tools into a single Re in Act wrapper tool, executes TypeScript/JavaScript inside a bounded runtime with built-in reason(), act(), and optional agent(), and preserves execution state across multiple request / response turns.

It also provides a fast proxy launcher on top of @mcpc-tech/aiyo-cli, so you can launch tools like OpenCode or Claude through a Re in Act-enabled proxy.

Install

pnpm add @one-agent/ria-proxy

Quick start

import { createOpenAI } from "@ai-sdk/openai";
import { createAiyo } from "@mcpc-tech/aiyo";
import { createReInActPlugin } from "@one-agent/ria-proxy";

const openai = createOpenAI({ apiKey: process.env.OPENAI_API_KEY! });

const adapter = createAiyo({
  defaultModel: "gpt-4.1",
  runtimeFactory: ({ modelId }) => ({
    model: openai.chat(modelId || "gpt-4.1"),
    modelName: modelId || "gpt-4.1",
  }),
  plugins: [
    createReInActPlugin({
      toolNames: ["read_file", "write_file", "list_dir"],
    }),
  ],
});

Fast proxy launch

npx @one-agent/ria-proxy launch opencode

Or use the launcher helpers directly:

import { launchWithRiaProxy } from "@one-agent/ria-proxy";

await launchWithRiaProxy("opencode", {
  model: "gpt-4.1",
});

What it does

1. Rewrites matching function tools into one top-level wrapper tool.
2. Teaches the model to write code in Re in Act style.
3. Injects reason(prompt, example), act(name, args), and agent(prompt, config?) into the runtime.
4. Suspends execution only when act() needs a real external tool result.
5. Resumes the same execution session when the next tool result arrives.
