Basically the tagline. After taking a break and coming back, I've forked a character that I really liked. When trying to improve it I put some thought into things and made some philosophies for different parts of a chatbot. Note that I'm using the free version of chub, so the instructions might not work as well for other models.

Macros

Basically keywords to make your instructions/definitions easier to work with. They are case sensitive though, the main macros are: {{char}} and {{user}}. {{char}} is replaced with the characters name when everything is sent to the AI, and {{user}} is replaced with the user's name.

Prompt Fields

The System Prompt is used for setting the overall behavior, role, and restrictions for the AI. Pre-History Instructions are like things the AI should know before responding. Chat History is pretty self explanatory, its the past messages between the user and the chatbot so far. Keep in mind the limited context window of LLMs. It's probably better to have auto summarization turned on in Configuration. Post-History Instructions alters or filters the draft response before the final output, and have a really strong influence. At least IME. They're also used for jailbreak prompts. I think it's best to write each section so that they synergize/complement each other.

Character Definition

When writing the description for the character don't worry about strict formatting. Just be consistent and write effectively, the same goes for System Prompt and Pre/Post-History Instructions. Although for System Prompt and Pre/Post-History Instruction I just use plaintext, no BS code formatting. In my descriptions I loosely use JSON formatting because I think the AI understands the "key":"value" format well. In fact I do something similar in the instructions for System Prompt and Pre/Post-History Instructions, but just using colons/semicolons and plaintext.

Example Dialogue is also important since it can influence responses greatly and also introduces bias. Make sure it encompasses all the aspects of your character you need it to somewhat equally.

Scenario is somewhat important I guess. "The current circumstances and context of the conversation and the characters." Don't worry about this part that much. It's part of the permanent tokens (like description) though so don't overdo it since it could ruin long-term chats.

Here's the fork I made so you have a reference to better understand stuff.
