feat(compare): side-by-side A/B/C compare tool (#23) - #149
Merged
Conversation
Adds a standalone `compare` MCP tool alongside confirm/ask/form/gallery: render 2+ full-content variants (Markdown text and/or image/video) as equal-width panes and let the user click one to pick, instead of a small thumbnail (ask) or an independent per-item verdict (gallery). - New Compare.svelte widget with sync_scroll (locked scroll across panes) and a shared max_height so panes stay visually equal. - Rust: compare case in the spec validator (>=2 variants, non-empty value) and the window-size estimator (scales with variant count, grows for image/video variants). - Mirrored compare tool in the Python aiui-mcp package for remote/headless sessions. - Extracted the Markdown-to-sanitized-HTML renderer out of Form.svelte into companion/src/lib/markdown.ts so both widgets share one DOMPurify allowlist instead of drifting. - docs/skill.md and CHANGELOG.md updated.
