How does it handle the 1M context beta header?

It identifies the 'context-1m-2025-08-07' beta header and removes it, as it is not currently supported with Opus 4.5, adding a comment for developer awareness.

Does this skill support Haiku model migrations?

No, this specific skill is designed only for migrating to Opus 4.5 and explicitly excludes Haiku 4.5 migrations.

Will it automatically change my system prompts?

By default, it only updates model strings. Prompt adjustments for behavioral issues like over-engineering or tool usage are only applied if specifically requested or if issues are reported.

Which cloud platforms are supported?

The skill provides updated model strings for the Anthropic API (1P), AWS Bedrock, Google Vertex AI, and Azure AI Foundry.

Migrates codebase references, API calls, and prompts from previous Claude models to the Opus 4.5 architecture.

소개

This skill provides a comprehensive, one-shot migration workflow for transitioning projects from Claude Sonnet 4.0, 4.5, or Opus 4.1 to the advanced Opus 4.5 model. It automates the identification and replacement of platform-specific model strings across Anthropic API, AWS Bedrock, Google Vertex AI, and Azure AI Foundry, while providing intelligent prompt adjustments to mitigate behavioral shifts such as tool overtriggering, over-engineering, and conservative code exploration. It ensures your integration remains up-to-date with the latest API parameters, including the new 'high' effort setting.
