Design for Agent Threads v0.3.0

Features

• /design wireframe: <brief> — a low-fidelity, grayscale wireframe focused on layout, hierarchy, and flow; reduces an existing design to its structure. (#5)
• /design states: <brief> — a component state sheet covering default, hover, focus-visible, active, disabled, loading, empty, error, and overflow, in light and dark themes. (#5)
• /design variations: <brief> — three (four if the brief asks) distinct full-page directions labeled A–D, shown side by side on a comparison board with rationale and a pick command for each. (#6)
• /design pick: <letter> [notes] — promotes a chosen variation to the root page as the fully built-out design, applying any notes, while keeping variations/ intact so you can pick again. (#6)
• /design spec: [notes] — a toggleable redline/spec overlay (press S or click "Show spec") that labels spacing, type, and color tokens on an existing design without changing the design itself. (#7)

Notes

• These are prompt modes on the existing design-static artifact — no new artifact kind, no manifest or schema changes.
• Desktop-only; requires Agent Threads v0.43.0 or later and Obsidian or Geode. Interactive previews and screenshot capture require Geode.
• Download both main.js and manifest.json to install or update the plugin.
• Verification: 143 tests passed, TypeScript typecheck clean, and the production build clean — all observed on main after merging #5, #6, and #7.
