v0.4.0-beta.1

[0.4.0-beta.1] - 2026-10-31

A prerelease for testing: npm dist-tag next, a GitHub pre-release with open-design-0.4.0-beta.1.mcpb. The Claude plugin stays on 0.3.0.

Claude Desktop extension: install open-design-0.4.0-beta.1.mcpb from this release to try it.

• The inline preview follows edits. In Claude Desktop Chat and Cowork, a design shown in the conversation updates in place after each round, so Claude shows it once. It waits while you write a comment, checks less often when idle and not while hidden. Inline preview
• The live preview in the Code tab's Browser pane, set up for you. Ask Claude to show the live preview and it adds an open-design-preview entry to .claude/launch.json (new tool set_up_open_design_browser_pane) and starts it. Each project gets its own port (5317–5416), the entry uses the npx beside your Node, and the pane opens the newest design (preview --root-latest). Claude Desktop
• Tool annotations. Every MCP tool says whether it only reads, writes in the workspace, or reaches another service (readOnlyHint, destructiveHint, openWorldHint).
• Links to the public gallery, behind a switch that stays off until the gallery goes public.
• Claude plugin 0.3.2: on Windows, the plugin's MCP server starts again when Node.js is installed under a path with spaces, such as the default C:\Program Files\nodejs (#66, thanks @mertol84).
• Claude plugin 0.3.1: each per-template skill's folder is now named like the skill (skills/od-prototype-card-twitter/), as the Agent Skills spec asks, so the Claude plugin directory can list them. Slash commands don't change.
• Add a Pinterest Pin export preset at 1000×1500 px with a 20 MB upload budget.
