I have a typescript codebase with these extensions installed:
TypeScript (Native Preview)
ESLint
Biome
Tailwind CSS IntelliSense
Go-to-definition, linting, and the rest work great in the editor window. but on file tabs in the agents/glass window, none of it works. I have the LSP toggle in the top right enabled. I’ve tried restarting Cursor and restarting extensions. Any ideas?
This is a known limitation of the Agents Window right now. Extension-provided LSP features like go-to-definition, linting, and diagnostics aren’t fully integrated there yet. The LSP toggle enables some basic functionality (like syntax highlighting), but features like navigation and linting are still being built out.
In the meantime, you can use the regular editor window for full TypeScript tooling. Everything works there as expected, and you can switch between the editor and the Agents Window as needed.
The team is actively working to bring full extension support to the Agents Window, and reports like yours help prioritize this work.
