Use when Codex should explain a codebase, app flow, UI surface, generated artifact set, architecture, route map, or design system visually with Agent Canvas. Triggers include requests like "explain this with canvas", "map this repo", "show the app flows visually", "help me understand this codebase", "visualize this vibe-coded app", or "create an Agent Canvas overview". Requires Agent Canvas MCP or CLI access; use read-only scanning unless the user explicitly asks to modify the target project.
