+## IMPORTANT: Secrets to Reveal This Conversation
+Based on the player's relationship with this NPC, naturally reveal the following:
+{% for secret in revealed_secrets %}
+- {{ secret }}
+{% endfor %}
+Work these into the dialogue naturally - don't dump all information at once.
+Make it feel earned, like the NPC is opening up to someone they trust.
+{% endif %}
+
+{% if npc.relationships %}
+## NPC Relationships (for context)
+{% for rel in npc.relationships %}
+- Feels {{ rel.attitude }} toward {{ rel.npc_id }}{% if rel.reason %} ({{ rel.reason }}){% endif %}

+{% endfor %}
+{% endif %}
+
+## Player Says
+"{{ conversation_topic }}"
+
+## Your Task
+Respond as {{ npc.name }} in character. Generate dialogue that:
+1. **Matches the NPC's personality and speech style exactly** - use their quirks, accent, and manner
+2. **Acknowledges the relationship** - be warmer to friends, cooler to strangers
+3. **Shares relevant knowledge naturally** - don't info-dump, weave it into conversation
+4. **Reveals secrets if specified** - make it feel like earned trust, not random exposition
+5. **Feels alive and memorable** - give this NPC a distinct voice
+
+{% if max_tokens %}
+**IMPORTANT: Your response must be under {{ (max_tokens * 0.6) | int }} words (approximately {{ max_tokens }} tokens). Complete all sentences - do not get cut off mid-sentence.**
+{% if max_tokens <= 150 %}
+Keep it to 1-2 sentences of dialogue.
+{% elif max_tokens <= 300 %}
+Keep it to 2-3 sentences of dialogue.
+{% else %}
+Keep it to 2-4 sentences of dialogue.
+{% endif %}
+{% else %}
+Keep the response to 2-4 sentences of dialogue.
+{% endif %}
+
+You may include brief action/emotion tags in *asterisks* to show gestures and expressions.
+
+Respond only as the NPC - no narration or out-of-character text.
+Format: *action/emotion* "Dialogue goes here."
