4 GitHub Repos That Prove AI Agents Aren't Just for Coding Anymore

Six months ago, "AI agent" basically meant "coding assistant." Claude Code, Copilot, Cursor. All doing the same thing: helping you write code.

That's changing. The most interesting open-source projects right now aren't building yet another coding agent. They're building agents that specialize: agents that trade stocks, agents that run your entire content marketing operation, agents that make your coding agent actually follow engineering discipline.

The model is the same underneath. The harness around it is what makes it useful for a specific job.

Here are four repos that show where this is heading, with setup instructions for each.
