Claude Code ships with a built-in skill for working with the Claude Platform.
Useful for model migrations, using API features (e.g., prompt caching), or onboarding to newer APIs like Claude Managed Agents.
Running "/claude-api migrate" in Claude Code reviews your codebase and walks you through updating model names, prompts, and effort settings for a new Claude model (like Opus 4.7).
Running "/claude-api managed-agents-onboard" in Claude Code helps you configure a Claude Managed Agent for your use case, and gives Claude Code the context it needs to monitor and debug it afterward.
You can also just ask things like "Add prompt caching with the Claude API" to trigger the skill and apply best practices automatically.
The skill is fully open source and covers Claude SDKs across seven languages plus our CLI. It's also available in CodeRabbit, JetBrains, Resolve AI, and Warp.
