What probably matters to you Section of the release
What
An IDE is a code editor such as VS Code. /ide can now install the Claude Code extension in the IDE you choose. While it works it shows "Installing the Claude Code extension in …", and then reports one of these:
installed
failed
not installed, with the reason
If the extension is installed but Claude Code cannot find it running, it tells you to restart the IDE or reload its window (Developer: Reload Window) and then run /ide again.
Why
You see whether installing the extension worked and what to do next, instead of being left guessing.

Anthropic's notes
Upstream's own release notes for v2.1.311 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.
Fixed /ide saying the VS Code extension was installed before the install finished or when it failed
Fixed /ide saying it had installed the JetBrains plugin when nothing was installed
Is this right?

Hard to understand Too vague Looks wrong Not relevant to me Too long Missing the detail I wanted Duplicate of another card
Clear Learned something new I can act on this Good catch
