Continuous Autonomy for the AI SDK

This project addresses the limitations of standard AI SDK workflows by introducing continuous autonomy through iterative agent loops. It targets developers building complex AI-powered applications who need robust task completion, verification, and persistence beyond single LLM calls. The primary benefit is enabling AI agents to reliably execute and complete tasks, even those requiring multiple steps, feedback, and retries.

How It Works

Ralph Loop Agent implements a "continuous AI agent loop" methodology, inspired by the "Ralph Wiggum technique." It wraps the core AI SDK's generateText function within an outer loop. This outer loop repeatedly executes an inner AI SDK tool loop (LLM interacting with tools) until a custom verifyCompletion function confirms the task is actually finished. If verification fails, feedback derived from the failure is injected back into the agent's context for the next iteration, ensuring progress towards the goal. This approach provides persistence and verification, crucial for complex or long-running operations.

Quick Start & Requirements

• Primary install: npm install ralph-loop-agent ai zod
• Prerequisites: Node.js environment, compatibility with AI SDK (uses AI Gateway string format).
• Note: This package is experimental, and APIs may change between versions.

Highlighted Details

• Iterative completion: Runs until verifyCompletion signals success or safety limits (iterations, tokens, cost) are met.
• Full AI SDK compatibility: Seamlessly integrates with existing AI SDK tools and models.
• Flexible stop conditions: Supports iterationCountIs, tokenCountIs, costIs, and combinations thereof.
• Context management: Includes built-in summarization for long-running loops to manage context effectively.
• Streaming support: Allows streaming the final iteration's output for responsive UIs.
• Feedback injection: Failed verification results provide actionable feedback for subsequent iterations.
• Includes a full-featured CLI agent with Vercel Sandbox, Playwright, PostgreSQL, and GitHub PR integration.

Licensing & Compatibility

• License: Apache-2.0.
• Compatibility: The Apache-2.0 license is permissive and generally compatible with commercial use and closed-source linking.

Limitations & Caveats

The project is explicitly marked as experimental, meaning APIs are subject to change. Defining an effective verifyCompletion function may require significant effort depending on task complexity. Long-running loops could potentially incur substantial token or cost usage if not properly constrained by stop conditions.
