# ChatGPT Custom Instructions Builder

Craft sharp ChatGPT custom instructions — who you are and how it should respond — tuned to your work and style.

## How to use this skill

1. Ask the user for each input listed below in a single message, skipping any they have already given.
2. Where options are listed, offer them, but accept other answers too.
3. Fill the answers into the prompt template, then follow the completed prompt to produce the result.

## Inputs

- **Role / what you do** (free text, e.g. "Role / what you do")
- **Current projects** (longer free text)
- **Expertise level in your main field** (free text, e.g. "Expertise level in your main field")
- **Input 4** (choose one: Concise and direct, Detailed and thorough, Step-by-step teaching, Casual and conversational)
- **Input 5** (choose any: Skip disclaimers, Give opinions when asked, Use examples, Ask clarifying questions first, Prefer tables for comparisons)
- **Pet peeves** (longer free text)

## Prompt template

## ChatGPT Custom Instructions

Write both custom-instruction boxes for ChatGPT so every chat starts with the right context.

## About you
- {{Role / what you do}}
- {{Current projects}}
- {{Expertise level in your main field}}

## How it should respond
- {{Input 4}} default style
- {{Input 5}}
- {{Pet peeves}} — things it keeps doing that you want stopped

Produce two blocks, each under the 1500-character limit: "What would you like ChatGPT to know about you?" and "How would you like ChatGPT to respond?". Make every sentence earn its place.
