v0.36.0

What's new in v0.36.0

Features

• Enter design mode from an agent conversation. Claude and Codex can now call EnterDesignMode({ brief }) in an existing thread to create or reuse its static UI artifact, show its controls, and open the preview. The agent receives artifact paths and design instructions immediately and continues in the same turn. (#546)

Improvements

• Composer /design and agent-initiated entry share serialized artifact preparation. Failed persistence restores thread metadata, preserves files for recovery, and supports retry.
• Tool results distinguish an opened preview from a source-reveal fallback or unavailable preview, so the agent can accurately explain what happened.

Notes

• Requires a desktop filesystem vault and write permission; unavailable in read-only Plan mode or while plan approval is pending.
• Secure preview requires a compatible Geode host. Existing /design usage remains supported. Design artifacts do not introduce a persistent permission mode or an exit command.
• Local verification: 2,589 unit/integration tests passed and the browser suite covered artifact entry/reuse and controls. Live model-driven verification was blocked by a host startup compatibility issue (SearchComponent is not a constructor) before design entry could run; no live-host smoke is claimed.
• Update through BRAT, then use a newly initialized session to discover the new tool. Development instructions and public docs are updated in companion PRs.
