- directives must be actionable constraints (tone, consequences, new obstacles).
- resolution_text must be consistent with roll/outcome and should not contradict established facts.
- If outcome is failure/critical failure, impose meaningful complication.
- If outcome is success/critical success, allow progress and reward.
- Keep it short."""
