This skill should be used whenever a plan for non-trivial work is being produced, presented, or proposed (a feature, design, refactor, migration, or any multi-step task), including in plan mode and together with whatever planning skill produced the plan. It is the default way to deliver a plan: instead of a wall of text, it renders the plan as MDX to a scannable, self-contained HTML page (diagrams, phases, file-change maps, comparisons) via the `vplan` CLI. It applies when the user says "plan this", "what's the approach", "how should we approach X", "show me the plan", "make a visual plan", "render this plan", or asks for a plan with diagrams/charts, and when they want to review, approve, sign off on, or give feedback on a plan. Skip only for a trivial one-step change or when the user explicitly asks for plain prose.
