no filename shown for read

Here is its ACP traffic:

no filename shown for edit

When my agent wants to edit a file, here's how it appears in the UI:

The UI is missing the filename that the agent wants to edit. This makes it hard to allow the action.

Here's the ACP traffic, meanwhile:

(It would also be great to show the diff in the UI, but for now I'd settle for just the filename.)
