Phase 1 of WebMCP support: a zero-dependency, feature-detected engine in packages/ui/webmcp plus a read-and-comment tool catalog for plan review and annotate (read_document, add_comments, update_comment, remove_comments, reveal, nudge_user, list_documents). No decision tools; the human approves. Zero footprint in browsers without document.modelContext (DOM, network, console, timers, and cookies identical to main), idle until called where the API exists, and never registered inside the annotate iframes. Adds an optional inReplyTo field on annotations for threaded replies. Client-only; no server changes.
AI-assisted (Claude) under maintainer direction.
