+# claude-design
+
+Claude Code plugin: be an expert on **Claude Design** (claude.ai/design).
+
+This plugin holds the knowledge, skills, agents, and commands needed to facilitate the entire process of designing and producing artifacts on Claude Design — from initial idea, through prompt engineering, through iteration, to a finished result.
+
+> **Status: 0.1.0-pre — bootstrap.** Skill/agent/command surface is being defined through the Voyage pipeline (`/trekbrief` → `/trekresearch` → `/trekplan` → `/trekexecute` → `/trekreview`).
+
+## Scope (to be confirmed via brief)
+
+- Deep knowledge of Claude Design as a product surface
+- Prompt-engineering patterns specifically tuned for Claude Design
+- End-to-end facilitation: discovery → prompt → preview → refine → ship
+- Reference material from the Anthropic cookbook and other authoritative sources
+
+## Status
+
+Pre-release. No commands or agents yet. See `ROADMAP.md` and `TODO.md` for the current Voyage iteration.
