Automates the migration of model strings and prompt configurations from Claude Sonnet and previous Opus versions to Claude Opus 4.5.

This skill facilitates a seamless transition to Claude Opus 4.5 by automatically identifying and updating model strings across primary platforms including Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry. Beyond simple string replacement, it intelligently adjusts system prompts to mitigate common behavioral shifts unique to Opus 4.5—such as tool overtriggering and over-engineering—while ensuring the removal of unsupported legacy beta features and the correct implementation of the new model effort parameters.
