Claude Design Integration [Gradual Rollout] / Claude Code v2.1.199

What

A new ClaudeDesign tool that lets Claude work directly with claude.ai/design — a collaborative canvas for decks, prototypes, landing pages, and UI mockups backed by your team's design system.

Usage

/design login         # Authenticate with claude.ai for Design access
/design consent       # Grant Claude agent access to your Design projects
/design <prompt>      # Route to Design operations (import, export, status, etc.)

Details

Operations include: list_projects, read_file, write_files, delete_files, finalize_plan, get_claude_design_prompt, render_preview, and more
Write operations (write_files, delete_files) require a plan_token obtained from finalize_plan first
Requires a claude.ai credential — not available via Bedrock, Vertex, or third-party providers
First-party Design server has a consent gate: the user grants Claude agent access once per account; /design consent handles this
Not available when nonessential network traffic is restricted

Status

Feature-flagged (tengu_omelette_fouet) — rolling out gradually.
