Agent Context - Attach reference projects for AI coding tools

H! I built Agent Context out of a frustration I kept running into. I’d constantly have useful code sitting in other projects. I'm a hacker so I have old services, experiments, internal tools but actually using them to guide my AI was messy. I’d either copy code around, open multiple workspaces, or try to explain everything manually to AI tools. None of it felt right. At the same time, I’ve been leaning more into AI-assisted development, and it became obvious that the biggest limitation isn’t the model, it’s the context you give it. So I started experimenting with a simple idea: What if you could treat external projects as first-class “reference context” inside your workspace? Agent Context is the result. It lets you attach external folders without polluting your repo, and makes those references visible, not just to you, but to AI tools as well. It’s a small utility, but it’s changed how I work across projects and how I think about giving AI better context. I’d really love feedback, especially from anyone using AI tools heavily in their workflow
