v0.4.0-beta.2

[0.4.0-beta.2] - 2026-10-31

A prerelease for testing: npm dist-tag next, and a GitHub pre-release with open-design-0.4.0-beta.2.mcpb and, new, open-design-chatgpt-plugin-0.4.0-beta.2.zip. The Claude plugin stays on 0.3.0.

ChatGPT desktop: run npx @feimacode/open-design-agent-kit@next install chatgpt, or install chatgpt --from the zip from this release.

• ChatGPT desktop. Each release now carries open-design-chatgpt-plugin-<version>.zip, a ChatGPT "Desktop only" plugin with the same skills as Codex and the server bundled in. npx @feimacode/open-design-agent-kit install chatgpt puts it in ChatGPT's personal plugin list (uninstall chatgpt removes it); it runs in the Work and Codex tabs and saves designs in Documents/Open Design. ChatGPT desktop
• Hosted server (preview). npx @feimacode/open-design-agent-kit-mcp --http serves Open Design as a remote MCP server over streamable HTTP, for ChatGPT web and Claude web connectors: a shared access token, one folder per session, tools that need your own computer hidden, per-session limits, and signed download links for exports. deploy/Dockerfile builds a container with Chromium. There is no public endpoint yet. Hosted server
• Inline preview in ChatGPT. The preview view asks ChatGPT for fullscreen through its own API when the standard request isn't available, and the render tools carry ChatGPT's short status lines while they run. scripts/probe-mcp-apps-host/ records what a host supports.
• Works with Impeccable. Briefs include a short "Product context" from the project's PRODUCT.md, and note a project DESIGN.md when no design system is active. set_active_design_system takes writeProjectDesignMd to save the design system as the project's DESIGN.md (never overwriting one), and after porting to app code the agent suggests /impeccable polish when Impeccable is installed. Works with Impeccable
• The inline preview doesn't ask Claude to show the design again after "Ask Claude to apply" or "Fix this piece", since the shown design already updates in place.
• Why the default design folder wasn't used. The desktop extension logs its folder on start, and the "no folder" message says why the Default design folder setting was skipped.
