Give AI instructions you don’t have to repeat
Write down your preferences once, then test them on a small task. Includes a personal-instructions template and a coding-project version.
By Jed May
I keep written instructions for how AI assistants should work with me: use plain language, preserve unrelated work, and distinguish what was checked from what was guessed. This is a small version you can adapt.
Get the template
Download the personal-instructions template. No signup required.
Try it on one task
- Open the template and change the preferences to match your needs. Remove anything you do not want.
- Paste the instructions at the start of a new AI chat, followed by one task you can check yourself.
- Try: “Turn these notes into a short email: I can attend Saturday. Ask what time to arrive. I can bring folding chairs, but I haven’t decided how many.”
- Read the draft. It should ask about arrival time without inventing a time or promising a number of chairs.
These are instructions to try, not a guarantee that the assistant will follow every rule. Keep a saved copy and paste it into another chat when needed; this exercise does not depend on automatic memory.
For coding projects: AGENTS.md
Download the coding-project template. In a Codex project, save it as AGENTS.md in the repository root. If that file already exists, merge the relevant lines instead of replacing it. Start a new session in that project and ask the assistant to summarize the instructions before giving it a small task.
Codex reads project instructions from AGENTS.md; other coding tools may use different conventions. See OpenAI’s instructions documentation for discovery and override behavior.
Check what changed
Did the draft follow your preferences? Did it add a fact you never supplied? Change one instruction and repeat the task. A short rule about a recurring problem is more useful than a long list you never inspect.
