GitHub launches gh-stack for building coding agents

GitHub just released gh-stack, a framework for building coding agents — AI tools that don't just write code, but actually run it, debug it, and iterate. The stack bundles three pieces into one architecture: a context window that keeps track of what the agent has seen, a tool integrations layer so it can talk to your repos and terminals, and an execution engine that lets the agent do real work instead of just generating text.

The idea is straightforward. Right now, a lot of coding assistants are really fancy autocomplete. gh-stack is trying to push past that by giving agents the full loop — read, write, run, debug, repeat. It's open source, it's designed for developers who want to build their own agents rather than rely on someone else's, and it ships alongside GitHub's existing Copilot tools.

Why this matters for us: more agents mean more tools for the people who actually write code day to day — and the ones who can build their own end up with a real edge over the ones still waiting on the next SaaS subscription.
