Claude Code v2.1.242 ·

Bash background runs honour the caller's constraint, stderr matching normalised

Valid foreground bash calls are no longer wrongly rejected, and stderr matching is tidier.

What

Input validation now checks whether the calling request permits or requires a background run before objecting to a foreground one, so a valid foreground call is no longer rejected. Standard error is trimmed and stripped before being matched against patterns, and tool results can carry appended trailing text.

Evidence

"tool_host_result_lines"

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