LetThemBuild for VS Code runs the room from inside the editor. Search for LetThemBuild in the Extensions view — in VS Code it comes from the Marketplace, in Cursor from Cursor's own marketplace. One build serves both.
What it asks the room
- Review my uncommitted changes — your working tree, for real defects.
- Review this file — the file you are in.
- Review the selection — the lines you highlighted.
- Ask the room… — anything, in your own words.
Findings that name a real file and line become squiggles in the editor, attributed to the seat that raised them. Everything else stays in the panel.
What it needs
The LetThemBuild desktop app, and its command line installed: Settings → Workspace & Account → Command line → Install the command…. The extension runs that ltb command and nothing else. It holds no keys of its own and talks to no model directly; the seats, keys, models and subscriptions are the ones already configured in the app.
If the command lives somewhere unusual, set letthembuild.cliPath in the editor's settings to its full path. On Windows that may point at ltb.cmd or straight at LetThemBuild.exe.
One thing to know
Quit the desktop app before running ltb from a terminal or the editor. The command line runs the app without its window, and the two share one settings and session store, so running both at once leaves them waiting on each other.
