Summary
Handles the grunt work of migrating your codebase from Sonnet 4.0, Sonnet 4.5, or Opus 4.1 to Opus 4.5. It searches for model strings across different platforms (Anthropic API, Bedrock, Vertex, Azure), updates them to the correct Opus 4.5 variants, removes unsupported beta headers, and adds the effort parameter. The real value is in the conditional prompt adjustments. It knows about Opus 4.5's quirks like tool overtriggering and over engineering tendencies, but only applies fixes when you actually report those issues rather than blindly changing everything. Use this when you're switching models and want someone else to remember all the platform specific string formats and behavioral gotchas.
