Claude Code gains design mockup feature and cost reduction tools
- Claude Code's new /design command lets developers create UI mockups in the terminal before writing code, generating multiple draft options as editable artboards.
- Anthropic released prompt caching guidance to reduce token costs on repeated inputs to 10 percent, though the cache clears when switching model modes.
- The design feature reads existing codebases to match current UI style and produces shareable mockups that carry into the build phase.
Where they differ. Ben's Bites focused on the design feature and auto-continue functionality, while AI Breakfast emphasized cost reduction through prompt caching and mentioned a model comparison interface test. Both describe genuine product additions that Anthropic released simultaneously.
How each of the 2 covered it
Claude Code introduced slash-design skill for creating editable UI artboards with visual tweaking before implementation, plus auto-continue for when usage timers reset.
Anthropic released guidance on reducing Claude Code token costs through prompt caching, which cuts repeat input costs to 10 percent, and is testing a side-by-side model comparison interface. The newsletter emphasizes that prompt caching is effective but gets cleared when swapping model modes or effort levels.
