What
The Bash tool is how Claude runs shell commands. When a Bash command is cancelled in the two cases handled here, the result Claude receives now states outright that nothing ran. The accompanying message is built in one shared way based on who stopped the call, replacing the separate wording each case used, such as a note that the call reached its deadline.
Separately, the Bash tool's own description, as captured under this release, now says the 10-minute maximum timeout applies to a foreground command.
Why
Claude gets a consistent signal that a cancelled command never started, so it is less likely to assume it had an effect.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The new wording of the cancellation message is not known.
