Migrates codebases and prompts from Claude Sonnet 4.0, 4.5, or Opus 4.1 to the latest Opus 4.5 model.
This skill streamlines the transition to Claude Opus 4.5 by automating the identification and replacement of model strings across various platforms including Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry. Beyond simple string updates, it provides logic to remove unsupported beta headers, configure high-effort parameters, and apply surgical prompt adjustments to handle behavioral changes like tool overtriggering, over-engineering, and sensitivity to 'thinking' keywords. It is an essential tool for developers looking to upgrade their LLM infrastructure while maintaining prompt reliability.
