Under the hood
A new error-kind list (network, not-found, permission, policy, validation, in-use, unknown) was added for classifying operation failures
What
Claude Code added a fixed list of error kinds — covering things like network problems, not-found, permission, policy, validation, in-use, and unknown — along with a matching set and validator to check values against it.
Why
This appears to support more precise classification of failures for some operation, though the finding doesn't identify which feature it belongs to.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It's unclear which specific operation or feature this error classification applies to.
