Fix It Once: build a reusable AI instruction

Workbench · Prototype · Evidence status: idea

Build a reusable instruction

Turn a correction you keep making to AI into an instruction you can reuse.

This browser tool formats what you write into a scoped rule, checks and a test prompt. It does not use AI to diagnose the mistake or evaluate the result. Test the instruction on your next comparable task; the mistake may still recur.

Use sanitized examples. Your entries stay in this page's memory: this tool does not send or save them. No account or email is required. Anonymous action counts may be measured separately; they never include your entries or generated instruction.
