+| # | Priority | Type | Action | Status |
+|---|----------|------|--------|--------|
+| 1 | HIGH | Missing Concept | Add Ultraplan row to Hot table — cloud-based plan drafting with browser review, inline comments, and flexible execution (`/ultraplan`) | ✅ COMPLETE (row added after Power-ups with beta badge and /ultraplan location) |
+| 2 | HIGH | Missing Concept | Add Claude Code Web row to Hot table — run tasks on cloud infrastructure at claude.ai/code with PR auto-fix and parallel sessions | ✅ COMPLETE (row added after Ultraplan with beta badge, claude.ai/code location, and Web Scheduled Tasks inline link) |
+| 3 | HIGH | Stale URL | Commands URL `/slash-commands` not in official sitemap — redirects to `/skills` page; docs say "commands merged into skills" | ❌ INVALID (RECURRING from 2026-03-10; URL still resolves via redirect; user chose to keep as-is) |
+| 4 | MED | Missing Concept | Add Desktop App row to Hot table — standalone app with visual diff, Dispatch, computer use, and parallel sessions | ❌ INVALID (RECURRING from 2026-03-17; user considers it a platform surface, not a configuration concept) |
