+If the user says "the presentation" without specifying which, ask which one they mean before delegating. Note that "the main presentation" or "the best-practice deck" generally refers to `presentation-claude-code` — the canonical reusable deck — but confirm if ambiguous.
 
 ## Why
 
-Each presentation has its own slide numbering, level system, journey-bar tick labels, and target audience. Per-presentation agents let each one keep a focused knowledge base and self-evolve without cross-contaminating the other. The vibe-coding agent preloads framework/structure/styling skills specific to that deck; the claude-gemini agent targets a non-technical audience and uses its own 6-level (2-day) system.

Per-presentation agents let each one keep a focused knowledge base and self-evolve without cross-contaminating the others. The vibe-coding agent preloads framework/structure/styling skills specific to that deck. The claude-gemini agent targets a non-technical GDG event audience and uses a journey-bar with 6 levels. The claude-code agent owns the canonical reusable best-practices deck (forked from the GDG one on 2026-04-30) — same audience voice, simpler structure (level-badge only, no journey bar), event-agnostic identity.
