Overview
Agent Tune is a personality-tuning file generator for AI agents. It lets you take a 5-minute test using research-grade instruments like MBTI, Big Five, Enneagram, DISC, or Attachment. Your results compile into a short Markdown file containing behavior rules for your AI agent, which you paste directly into system prompts for Claude, ChatGPT, Cursor, Gemini, or any API. No signup, email, or subscription is required—the tuning file is yours permanently.
Application scenarios
Thinking partners
Get an AI that pushes back on flawed premises and names assumptions instead of just agreeing.
Coding sessions
Receive code without unnecessary chatter or apologies—just the output you'd write, faster.
Writing and editing
Have an editor that preserves your voice, avoids adding unwanted punctuation, and edits drafts instead of rewriting them.
Problem-solving
Use the AI as a sounding board that stops asking what kind of help you want and delivers structured answers directly.
Project mapping
Identify blockers by having the AI ask about upstream dependencies rather than offering generic encouragement.
API integrations
Apply the same tuning file to any API call, ensuring consistent behavior across different models and platforms.

Target users
Agent Tune is built for professionals who want their AI to match their thinking style: thinkers who need a sounding board that pushes back, coders who want direct code without chatter, and writers who need an editor that respects their voice. It's also useful for anyone using Claude, ChatGPT, Cursor, Gemini, Copilot, or API-based agents who want consistent, calibrated behavior across every conversation and model.
How to use
Take a 5-minute test from the five research-grade instruments (MBTI, Big Five, Enneagram, DISC, or Attachment). No signup or email is needed. Receive your tuning file as a short Markdown document containing behavior rules for your agent. Paste the file into your system prompt for Claude, ChatGPT, Cursor, Gemini, Copilot, or any API call. The tuning works immediately on the next message.
Effect review
Agent Tune delivers exactly what it promises: a tangible, portable tuning file that changes how an AI responds. The test instruments are research-grade, and the output is concise—just a dozen lines that cancel defaults like "great question" openers and generic encouragement. For users who want their AI to push back, name flawed premises, or skip unnecessary chatter, this tool provides a clean, no-fuss solution. The lack of signup, subscription, or lock-in makes it especially practical for anyone who switches between models or APIs regularly. The real test is whether the personality match feels accurate in practice, but the concept is sound and the implementation is refreshingly straightforward.
