Mantella is a Skyrim and Fallout 4 mod which allows you to naturally speak to NPCs using Whisper (speech-to-text), LLMs (text generation), and xVASynth / XTTS (text-to-speech).
When checking the length of Mantella conversations histories, there is a "close friend" level, but this level does not exist for the npc.relationship_rank check. This "close friend" level needs to be also added for npc.relationship_rank.
"trust" is used to tell an LLM how well a given NPC knows the player:
