ChatGPT AutoExpert
by spdustin
A set of custom-instruction prompts that turn plain ChatGPT into a more rigorous conversational or coding assistant, not an MCP tool server, but a prompt system predating MCP.

About
ChatGPT AutoExpert isn't an MCP server. It's a pair of custom-instruction templates you paste into ChatGPT's settings. The Standard Edition rewrites your question into a sharper version of itself before answering, picks an appropriate expert persona and reasoning framework for the topic, states its reasoning explicitly instead of just asserting an answer, and adds slash commands for quick summaries, counterarguments, or self-critique.
The Developer Edition targets ChatGPT Pro users with Advanced Data Analysis access: it adjusts how verbose generated code is, keeps a running file/symbol tree across a multi-turn coding session, supports a `/memory` command to checkpoint and reload conversation state, and can install custom Python wheels inside the analysis sandbox. Both editions are just markdown text pasted into ChatGPT's custom-instructions fields, nothing to run, no server process, no tool calls.
Key features
- Rewrites vague questions into precise ones before answering
- Auto-selects an expert persona and reasoning framework per topic
- Slash commands for summaries, alternate viewpoints, and self-review
- Developer Edition tracks file/symbol state across a coding session
- `/memory` command to checkpoint and resume long Advanced Data Analysis sessions
- Inline links to related topics to reduce hallucinated claims
Use cases
- Getting more rigorous, less hedged answers out of plain ChatGPT without any code
- Running longer coding sessions in ChatGPT's Advanced Data Analysis without losing file context between turns
- Quickly generating counterarguments or self-critiques of a draft answer via slash commands
- Teaching or research use where seeing the model's chosen reasoning framework matters as much as the answer
Available tools

Frequently asked questions
Is this an MCP server I can add to Claude or another client?
No. It's plain-text custom instructions for ChatGPT, written before the Model Context Protocol existed. There's no server process or tool-call interface to install.
Which edition should I use?
Standard Edition for general conversation and writing; Developer Edition only if you have ChatGPT Pro with Advanced Data Analysis and are doing coding work.
