Unclear It's not stated which tool identifier this new entry corresponds to, though the fields match a shell command's output.
What
Claude Code keeps an internal list, keyed by tool, of which result fields a tool is allowed to report (used for things like comparing or caching a tool's output). A new entry was added to this list for the Bash tool, allowing its results to carry stdout, stderr, interrupted, and timedOutAfterMs. Previously, the entries in this list only allowed a structuredPatch field, used by file-editing tools.
Why
This lets the system track a command's standard output, standard error, whether it was interrupted, and how long it ran before timing out, as recognized fields on Bash tool results.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
