Turn your corrections into a saved skill

Build-along · ~25 min at your own keyboard

A list of corrections only helps if the assistant reads it before it writes. Put the rules in a saved skill or in a project's instructions. Ask the assistant to write the file for you, then read what it wrote. This step matters. Assistants add rules. They fill gaps with habits that sound reasonable and are not yours. A rule you never said will shape every answer from now on. Read each line and ask if you said it. Strike the ones you did not. Then test in a fresh chat with a new task.

Checkpoints

  • ▸You should now see a saved file built from your corrections.
  • ▸You should now see a list of lines you struck or rewrote, with a reason for each.
  • ▸You should now see one of your rules applied in a fresh chat.
The three ways this goes wrong
  • The file has twelve rules and you only wrote four. — Strike the eight you did not say. If one is useful, add it to your list in your own words first, then keep it.
  • You read the file once and it all looked fine. — Read it again slowly, one line at a time, and ask yourself whether you said that. Look hard at any rule about tone.
  • The fresh chat ignores your rules. — Check that the file is saved in the place your assistant reads, and that the new chat is inside that project.
