How does it handle the 'thinking' parameter in Opus 4.5?

It identifies if extended thinking is disabled and suggests replacing the word 'think' in prompts with alternatives like 'evaluate' or 'consider' to avoid model confusion.

Will it migrate my Claude Haiku implementation?

No, this skill explicitly excludes Haiku models. It is optimized only for the high-performance Opus 4.5 migration path.

Can it fix issues where the model calls too many tools?

Yes, the skill includes logic to soften aggressive instructions that cause 'tool overtriggering' in Opus 4.5 compared to previous versions.

Which models can I migrate from using this skill?

This skill is specifically designed to migrate projects from Claude Sonnet 4.0, Sonnet 4.5, and Opus 4.1 to the Opus 4.5 model.

Does this skill support AWS Bedrock and Google Vertex AI?

Yes, it handles platform-specific model strings for the Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry.

Migrates codebases and prompts from earlier Claude models to Opus 4.5 with automated model string updates and behavioral refinements.

The Claude Opus 4.5 Migration Assistant is designed to streamline the transition from Claude Sonnet 4.0, Sonnet 4.5, or Opus 4.1 to the more advanced Opus 4.5 model. It automates the tedious identification and replacement of model strings across various platforms—including Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry—while simultaneously cleaning up unsupported beta headers. Beyond simple string replacement, the skill provides expert guidance on adjusting prompts to account for Opus 4.5's unique behavioral differences, such as its sensitivity to 'thinking' parameters and its tendency toward over-engineering or tool overtriggering.
