Does this skill support migrating to Haiku 4.5?

No, this specific skill is focused on the migration path to Opus 4.5 and explicitly excludes Haiku models.

What is the 'effort' parameter mentioned in the migration?

Opus 4.5 supports an 'effort' parameter; this skill helps set it to 'high' to ensure the model provides the highest quality reasoning for your updated codebase.

Which cloud platforms are covered by the model string updates?

The skill handles model string formats for the Anthropic API (1P), AWS Bedrock, Google Vertex AI, and Azure AI Foundry.

How does it handle existing XML tags in my prompts?

The skill is designed to integrate updates thoughtfully, matching your existing style and placing new guidelines within appropriate XML tags like or .

Automates the transition of codebase model strings and system prompts from legacy Claude versions to the high-performance Opus 4.5 model.

This skill provides a specialized workflow for migrating AI-powered applications from Claude Sonnet 4.0, 4.5, or Opus 4.1 to the latest Opus 4.5 model. It simplifies the technical debt of model upgrades by automatically updating platform-specific model strings across AWS Bedrock, Google Vertex AI, Azure, and Anthropic's native API. Beyond simple string replacement, it intelligently refines system prompts to account for Opus 4.5's unique behavioral characteristics—such as its increased sensitivity to tool-calling instructions and 'thinking' keywords—ensuring your migration is both functional and optimized for the new model's logic.
