What
Requests to your editor for diagnostics now have a time limit, repeated workspace requests are collapsed while one is in flight, and after a fixed number of consecutive baseline timeouts Claude Code stops taking baselines for the rest of the session and logs why.
Details
Telemetry records how long each call took and how many timeouts have run consecutively; outcomes include a path mismatch and a skip because a fetch was already in flight.
Diagnostics are skipped entirely for one known server name.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
