Claude Code ultraplan

In plain words

Claude Code ultraplan is a developer tool that helps engineers plan codebase implementations in the cloud rather than locally. The /ultraplan command generates an implementation plan that users can review, annotate, and revise before execution. It integrates with Claude Code and allows developers to approve plans before they run, streamlining the planning phase of coding work.
