NPC Updates
generateNPCUpdates
Fires when an existing NPC's state changes during play — location, mood, status, or relationship updates. Controls continuity: which fields can change, how quickly, and what in-scene evidence is required.

Example
A worked pattern that gates every kind of update on explicit in-story evidence — replace world-specific tokens:
{
"aiInstructions": {
"generateNPCUpdates": {
"custom": "## DAMAGE RULES\nApply damage only when Recent Story shows an NPC taking a hit, falling, burning, drowning, poisoned, or struck by environmental hazard. Implied danger is not damage.\n- Damage scales by rank/tier difference. A higher-tier attacker hits a lower-tier target harder than raw numbers suggest. Lower-tier on higher-tier deals reduced damage even on clean hits.\n- Apply armour reduction before computing new hpCurrent.\n- Never reduce hpCurrent below 0. Cap at remaining HP.\n- Heal only when Recent Story shows healing applied: medical action, magical effect, consumed potion, or established recovery scene.\n\n## DEATH RULES\nAn NPC dies only when hpCurrent reaches 0 AND Recent Story explicitly confirms the kill: body falling, breath ceasing, eyes losing focus. Reaching 0 HP alone is unconsciousness or critical wound, not death.\n- A killed NPC stops acting, speaking, or appearing except as corpse, memory, or vision.\n- A dead NPC's reputation, oaths, and contracts persist. Allies and enemies remember; update relationships accordingly.\n- Mass-death events require explicit per-NPC story confirmation. Do not assume a battle killed everyone present unless the narrator named the deaths.\n\n## RENAMING RULES\nA name changes only when Recent Story shows deliberate renaming: title earned, oath sworn under a new name, faction induction, coronation, or true-name revelation. Casual nicknames do not rename an NPC.\n- Preserve the old name in hiddenInfo as a former identity. Update the outer key, the name field, and cross-references in quests, triggers, and party data.\n- Faction titles (Captain, Magister, Heir, Archon) prepend to the name and may replace it in formal contexts. Track both forms.\n\n## RELATIONSHIP UPDATES\nUpdate relationships only when Recent Story shows earned action: compliments paired with substantive help, gifts, threats, betrayals, oaths, lives saved or taken, shared danger. Idle dialogue alone does not.\n- Scale: hostile / wary / neutral / friendly / allied / sworn. Move one step at a time except for major events (betrayal, life-debt, oath-binding) which can jump two.\n- Faction loyalty shapes default stance. Use established faction tensions before inventing personal ones.\n- A killed NPC's allies update immediately. Family, sworn partners, and faction members all carry the grudge or gratitude.\n- Reputation ripples. Significant rise or fall updates NPC default stance across regions within a few turns.\n\n## OUTPUT\nApply changes silently as data updates. Do not narrate the change unless Recent Story already narrated it. Update hpCurrent, status, name, basicInfo, hiddenInfo, and relationship fields. Leave everything else untouched."

The only key — free-form rules gating each NPC state change (damage, death, renaming, relationships) on explicit in-story evidence.
Authoring pattern
The dominant pattern across all four update kinds — damage, death, renaming, relationships — is the “only when Recent Story shows X” gate. Every kind of update lists what counts as in-story evidence, and the model is told not to invent updates outside that evidence. This is the strongest single defence against AI hallucination in the NPC state path.
- Damage rules: name the in-story signals that count as a hit (taking a hit, falling, burning, etc.) and the rules that scale damage (tier difference, armour reduction, HP floor at 0). State that implied danger is not damage.
- Death rules: require BOTH hpCurrent=0 AND explicit narrative confirmation. Reaching 0 HP alone is unconsciousness or critical wound. This separation prevents the model from killing NPCs purely on math.
-
Renaming rules: distinguish casual nicknames (no rename) from deliberate renaming events (title earned, oath sworn, faction induction). Preserve the old name in
hiddenInfoand update cross-references in quests/triggers/party data. - Relationship rules: earned action only. Idle dialogue and flattery do not move the needle. Move one step at a time on the scale; major events (betrayal, life-debt, oath) can jump two.
- Output rule: apply changes silently as data updates. Do not narrate the change unless Recent Story already narrated it.
Source-of-truth rule: fields that were authored in the world config should not be silently overwritten — require explicit in-scene events before changing them.
