  • Relevant campaign-level documents reviewed (world lore, prior session notes)

2. NPC Readiness

list_characters(character_type: "npc", module_id: module_id)

  • Maps uploaded and tokens placed (list_maps, get_map)

4. Plot Thread Check

  • Current plot hooks are clear
  • Player goals acknowledged
  • Clues/information properly placed
  • Multiple paths to success exist

5. Contingency Prep

  • "What if they skip X" planned
