Anthropic Releases Migration Command for Claude Opus 5 in Claude Code
Anthropic has introduced the `/claude-api migrate` command in Claude Code, allowing developers to easily upgrade their existing workloads to the newly released Claude Opus 5 model. This built-in skill automatically updates model strings and suggests optimized prompts tailored for Opus 5. This update simplifies the transition to Claude Opus 5, which offers significant improvements in coding, professional tasks, and long-running agents. By automating the migration process, Anthropic reduces the friction for developers looking to adopt their latest, more cost-effective model. The migration tool is executed directly within the Claude Code terminal interface using the `claude-api` skill. Beyond updating API model identifiers, it analyzes existing prompts to recommend adjustments that leverage Opus 5's specific capabilities.
