What
Claude Code sorts failed requests to the API into categories. It uses them to decide whether suggesting a different model might help, and it records them in its usage data. Several of these names have changed:
anotherModelCouldHelp is now fallbackModelCouldHelp.
connection is now connectionLost.
rejected is now badRequest.
unrecognised is now unknown.
watchdog is now stalled.
denied is a category that is now checked first.
The error logged after retries are used up now also covers the case no_api_attempts_left. The check for a rate limit error now compares the correct value.
Why
Anything that reads these logged values will see the new names instead of the old ones. The corrected rate limit check means that case is recognised as intended.
How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtIt is not clear what reads these renamed categories apart from Claude Code's own logging.
