GoFannon: Stop Rewriting AI Tools for Every Framework

Write once, use anywhere—an open-source tool library for portable AI agents

The Problem: Framework Lock-In Wastes Time

If you’ve built and migrated AI agents, you’ve done this before:

1. Write a tool for LangChain (e.g., a weather lookup).
2. Switch to AWS Bedrock—now rewrite it.
3. Try SmolAgents? Yep, rewrite it again.

This is inefficient. Most AI frameworks use similar underlying specs (like OpenAI’s function calling), but each has its own quirks. GoFannon fixes this by letting you write a tool once and export it to any framework.

How GoFannon Works

1. Standardized Tool Definitions

Every GoFannon tool inherits from BaseTool and defines:

• A definition (following OpenAI’s standards) for inputs/outputs.
• A fn() method with your core logic.

Example from the on of our example notebooks.

2. One-Line Framework Exports

Convert any tool to your framework of choice:

No rewrites. No boilerplate.

3. Pre-Built Tools

Gofannon includes production-ready tools, like:

• Wikipedia search
• Basic math operations
