What problem does it solve?

Migrating existing Claude prompts and code to the latest Opus 4.5 model can be complex due to API model string changes and subtle behavioral differences. This Skill automates the update process, ensuring your AI applications leverage Opus 4.5's full capabilities without manual headaches.

Core Features & Use Cases

• Automated Model String Updates: Automatically identify and replace old model strings (Sonnet 4.0, 4.5, Opus 4.1) with the correct Opus 4.5 identifiers across various platforms (Anthropic API, AWS Bedrock, Google Vertex AI, Azure AI Foundry).
• Prompt Adjustment Guidance: Provides specific recommendations and snippets to fine-tune prompts for Opus 4.5's known behavioral differences, such as preventing over-triggering of tools or over-engineering solutions.
• Effort Parameter Configuration: Guides on adding the effort beta parameter to optimize model performance for deep reasoning or cost efficiency.
• Use Case: Update a Python codebase from claude-sonnet-4-20250514 to claude-opus-4-5-20251101, ensuring all API calls are correctly configured and prompts are adjusted for optimal performance.
