Agent System Prompt Tuner

A well-tuned system prompt can be the difference between an LLM that gives generic responses and one that nails your use case. But finding the right prompt takes iteration—testing different instructions against real inputs and comparing outputs. Without tooling, this means manually copy-pasting into a chat interface over and over.

This workflow handles that for you. Put your prompts and test cases in a Google Sheet, run the workflow, and get all responses written back automatically. All you need is a Google Sheet and a NoClick account.
