Instruction builder

Custom instructions fail for a boring reason: people write what they want the model to be, and never what they want it to stop doing. This asks for both. Pick what applies, edit the result, paste it into your settings once.

1. Who should the model be

Or write it yourself

2. What it is helping with Context it should assume every time Whatever you would otherwise retype at the start of every conversation.

3. How answers should read

4. What it should stop doing

This section is what makes the difference. Be specific.

5. Output shape optional

Language of answers

6. Anything else Your own rules, one per line

Your system instruction

Pick something on the left and it appears here.

Where this goes. ChatGPT: Settings, then Personalisation, then Custom instructions. Claude: Settings, then Profile, or a project's custom instructions. Gemini: Saved info. For a local model it belongs in the SYSTEM block of a Modelfile.

Read it before you paste it. A rule you did not mean is worse than no rule, because you will spend a week wondering why answers changed.

Or start from one that exists
