Automates the migration of model strings, API calls, and prompts from legacy Claude models to Opus 4.5.
This skill provides a structured workflow for upgrading existing Claude-powered applications to the Opus 4.5 model. It handles the replacement of model strings across multiple platforms including the Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry. Beyond simple string replacement, the skill manages the removal of unsupported beta headers, configures optimal effort parameters, and provides targeted prompt engineering snippets to mitigate specific behavioral changes such as tool overtriggering, over-engineering, and code exploration passivity.
