I build developer tools.
Lately, for AI agents too.

I'm a software engineer at JetBrains, working on Rider's agent infrastructure: skills, hooks, and MCP integrations. My background is in editor architecture and code completion.

This is my notebook for the questions that come out of that work. What makes a tool useful to an agent? What can an IDE bring to the loop? And how do we measure whether any of it helps?
