sqlite-utils 4.0rc2, mostly written by Claude Fable (for about $149.25)
Simon Willison released sqlite-utils 4.0rc2, with most code written by Anthropic's Claude Fable model for about $149.25. Fable identified a critical bug in delete_where() that caused data loss by never committing transactions. Willison then had GPT-5.5 review Fable's changes, finding an additional side-effect issue where db.query() auto-commits writes before raising an error.
The release fixes a critical data-loss bug and demonstrates cross-model code review catching subtle side effects.
