Classify the presentation type before selecting the deck structure. Use the user's prompt, uploaded files, project sources, templates, brand guides, data, and prior examples as the primary authority. Do not force a classroom lesson structure onto corporate, proposal, verification, or investor decks.
Use SKILL.md as the primary steering file. For each user request, route the task to a deck type, then load the matching reference file. Prefer source-grounded plans and explicit QA reports.
