Pre-Session Checklist
1. Content Readiness
Load the module being run and campaign-level context:
# Campaign-level documents (world lore, session notes)
list_documents() # omit module_id for campaign-level docs
# Module content
get_module_details(module_id)
list_documents(module_id)
Verify:
- Backstory or description document exists and is complete
- Read-aloud text prepared for key moments
- DM notes cover contingencies
- Maps/handouts referenced are available
- Relevant campaign-level documents reviewed (world lore, prior session notes)
2. NPC Readiness
list_characters(character_type: "npc", module_id: module_id)
# Also check by location if the session spans areas:
list_characters(character_type: "npc", location: "Tavern District")
For each NPC players will likely encounter:
- Name, role, location defined
- Motivation and goals clear
- Key information they know documented
- Ability scores set (for skill checks during play)

- Monster stat blocks accessible (verify via
search_catalog(category: "monster")) - Tactics noted in DM notes
- Terrain/environmental factors documented
- Treasure/loot defined
- 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
- "What if NPC dies" contingency
- Backup hooks ready
- Improvisation anchors noted
