Comprehensive guide for building full-stack applications with Convex and TanStack Start. This skill should be used when working on projects that use Convex as the backend database with TanStack Start (React meta-framework).

Orchestrates debates among multiple advisors on high-impact architecture, technology, or product decisions. Dispatches 3–5 domain-archetype subagents (pragmatic-engineer, architect-advisor, security-advocate, product-mind, devils-advocate, the-thinker) through opening statements, tensions, position evolution, and synthesis phases. Preserves dissent and delivers actionable recommendations with documented risks. Use when evaluating trade-offs, stress-testing a PRD or tech spec, resolving dilemmas with multiple viable options, or when a decision needs diverse expert perspectives. Don’t use for simple yes/no questions, factual lookups, creative brainstorming without trade-offs, or tasks where one expert perspective is enough.

Generate keyboard-navigable HTML slideshow decks for presentations, tech talks, leadership briefings, onboarding walkthroughs, and any sequential visual narrative. Use whenever the user wants slides, a deck, a presentation, a tech talk, a brown-bag, a briefing, or any sequential walkthrough — especially when they want to share via a link rather than as a PowerPoint or Keynote file. Prefer HTML over .pptx whenever the deck contains live code, embedded interactivity, or will be shared as a URL
