What
The Monitor tool's guidance text now varies based on whether the session is interactive. In interactive sessions (where the user is present at a terminal), Claude is now told to use a foreground Bash until loop for single-notification "tell me when ready" cases. In non-interactive/background sessions, the previous run_in_background recommendation is kept.
Details
- For single-notification use cases in interactive sessions: "run the command in the foreground with Bash, exiting when the condition is true"
- For single-notification use cases in non-interactive sessions: "use Bash with
run_in_background" - The "don't use unbounded command for a single notification" warning likewise adapts its phrasing to the context
Evidence
Monitor tool description function (search for "run the command in the foreground with Bash")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
