These issues and PRs concern a bug where the agent's retry logic fails to match the specific 400 error wording returned when a custom OpenAI-compatible provider does not support the 'none' value for reasoning_effort. The fixes aim to correct the pattern matching so requests are retried without reasoning when this error is encountered.
