Contact
There is no contact form here, and that is deliberate. A form needs either a server to receive it or a third-party script to handle it, and this site has neither — which is the same reason your prompts never reach us. An email address costs you one extra click and costs you nothing in privacy.
Especially worth writing about
A check that fires on a good prompt. This is the most valuable bug report we can get. A checker that cries wolf gets ignored, and then it catches nothing at all — so a false positive is a more serious defect than a missed problem. If one of the nine checks flagged something that was fine for your task, we want the prompt.
A check that missed something. Less urgent, but useful.
A guide that is wrong. The claims in the guides are demonstrated by the live checker, so they cannot silently drift — but the reasoning around them can still be mistaken.
A prompt worth adding to the library. If you have one that earns its place, send it.
We read everything. We do not always reply quickly.
