Does this skill handle multi-cloud model strings?

Yes, it provides and updates specific model strings for the Anthropic 1P API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry.

Which models can be migrated using this skill?

This skill supports migrating from Claude Sonnet 4.0, Sonnet 4.5, or Opus 4.1 to Opus 4.5. It is specifically designed for these transitions and excludes Haiku models.

How does it handle behavioral differences in Opus 4.5?

The skill includes guidelines to soften tool-triggering language, prevent over-engineering, and improve code exploration by adjusting system prompts and using XML tags.

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

Opus 4.5 allows for an effort parameter. This skill helps configure that parameter to 'high' to ensure the model delivers the highest quality reasoning and output.

API 개발

Migrates codebases and prompts from previous Claude models to Opus 4.5 with optimized parameters and behavioral adjustments.

The Claude Opus 4.5 Migration skill facilitates a seamless transition for developers moving from Sonnet 4.0, 4.5, or Opus 4.1 to the latest Opus 4.5 model. It automates the updating of model strings across multiple platforms including Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry. Beyond simple string replacement, the skill intelligently refines prompts to address Opus 4.5-specific behavioral differences—such as tool overtriggering and over-engineering—while ensuring optimal performance by configuring high-effort parameters and removing unsupported beta headers.
