TTRPG Session Forge

Q: How do I know the TTRPG Session Forge output is good?

The skill verifies itself against its own quality checks: No scene requires a specific player choice to function — every scene; states what happens if ignored; Clues are location-independent — the mystery survives any route; NPC cards pass the "playable in 5 seconds" test: motive + voice hook +.

🔵 Stable🕐 updated 2026-07-26 🔷 SkillSpec L3 pm-newgen

Prep tonight's TTRPG session in 30 minutes — three scenes with stakes, NPC voice cards, a flexible encounter, treasure/clues, and the 'players did something insane' toolkit — plus session-zero safety tools for new tables. Use when a game master says 'prep my D&D session', 'my players derailed everything', 'I need an NPC on the fly', or 'help me start a campaign'. Produces a one-page session plan built to survive contact with the players.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓No scene requires a specific player choice to function — every scene

✓states what happens if ignored

✓Clues are location-independent — the mystery survives any route

✓NPC cards pass the "playable in 5 seconds" test: motive + voice hook +

✓a sayable line

✓System-specific numbers are deferred to the GM's books, not invented

✓The plan fits one page; prep time target ≤30 minutes honoured

✓Session-zero pack included whenever the table is new, without being asked

⚠️ What it refuses to do

Do not write a plot the players must follow — railroads prep beautifully

and play terribly

Do not prep endings; prep pressures and let the table find the ending

Do not invent stat blocks or rules for named systems — structure is

portable, math belongs to the books at the table
