Theming Tools

Theming Tools gives the Syrus Chat agent a preview_theme tool: it can draft a candidate color theme and pop it open for the user against the real Style Guide page, so token choices are judged on actual Button/Input/Card/etc. components instead of a recreated mockup.

The underlying Theme model stays in core (same precedent as WhiteboardSnapshot for whiteboard_tools) — this plugin only owns the preview_theme MCP tool and the broadcast wiring that opens the preview modal.

What It Adds

• A preview_theme chat MCP tool that upserts a draft Theme row for the calling user.
• An app-event broadcast that opens a live Style Guide preview modal in the chat UI.

When To Enable

Enable Theming Tools when chat agents should be able to design and preview custom color themes with a user. Keep it disabled on installations that don't want agent-assisted theming, or until install_theme and full theme CRUD land in a follow-up.

Operational Notes

preview_theme is safe to call repeatedly — each call updates the same draft theme in place instead of creating a new row. It does not persist a theme as installable; that lands with install_theme in a follow-up plugin update, alongside contrast validation.
