Create a new Claude Design project. Returns { projectId, url }. Does NOT start generation — call generate next.

Start generation for an existing project. Returns immediately once generation has STARTED — generation takes ~5 minutes, poll get_status.

Poll generation status. Returns { status: 'generating'|'ready'|'error'|'draft', detail?: string }.

Send a chat message to iterate on the design. Non-blocking: returns once the run has STARTED (~seconds). Poll get_status until 'ready', or run pnpm run watch:status in the background for an auto wake-up.

List files generated for the project (tokens, components, screens, SKILL.md, etc.).

Read a single generated file by its path within the project.

Write all generated files into destDir, preserving structure.

PRIMARY handoff to Claude Code. Mints the official capability URL to the server-built bundle and returns a ready-to-run command (Fetch … / Implement: …). The URL is fetchable without auth and expires shortly. Pass destDir to also download + extract the bundle locally (returns projectDir, ready for pnpm run scaffold:ui).

DEPRECATED — prefer mint_handoff. Builds a LOCAL handoff bundle (project/ files + chats/ transcripts + README) by reading every file over CDP. Use only for offline bundles or to commit transcripts into a repo.

Publish the design system (make it shareable / consumable as a Skill).

Set this design system as the default one used by Claude Design.

List all known design system projects.

List ALL projects (both design systems and design projects) with their kind.

Create a new design PROJECT (screens/app/prototype), optionally attaching design systems. Returns { projectId, url }. Call generate to start from the brief, or send_message to drive it.

Bind a design system to a project so it reuses that system's tokens/components.

Unbind a design system from a project.

List the design systems currently bound to a project (with names).

Pull the latest version of bound design system(s) into the project.

List a project's conversations (chats): { chatId, title, turns, active }.

Start a fresh conversation in the project (then use send_message).

Send a prompt / revision to the project chat. Non-blocking: returns once the run has STARTED. Optionally target a specific conversation by conversationId. Poll get_status (or pnpm run watch:status) for completion.

Grep the project's files for a pattern. Returns { path, line, context } matches.

Create or overwrite a file in the project with the given UTF-8 content.

Replace an exact string in a project file (single occurrence edit).

Delete a file from the project.

Rename a project.

Delete a project permanently.

Duplicate a project. Returns the new { projectId, url }.

Remix a project into a new one (optionally including chats).

Mark/unmark a project as favorite.

Get account usage/quota status (5-hour and 7-day windows).

Open the project as a Claude Code session. Returns { sessionUrl }. May be gated per account.
