Both tools used the same Claude Opus 4.6 model. OpenCode completed the refactor in 7 minutes with 0 code mistakes; Claude Code took 14 minutes and made 2 code-level errors (wrong refactor order, incomplete cascade). Both hit identical npm shim environment issues. Key takeaways: bottom-up refactor order prevents cascade errors, forcing agents to log mistakes in MISTAKES.md improves auditability, and detailed operating-procedure prompts outperform simple task descriptions for large migrations. The post includes a full production-ready prompt template for future state management migrations. ## Full article daily.dev links to this article rather than hosting it.
