Open on GitHubWhat RegEx Generator does
This prompt configures the model to act as a regex generator. You specify the target format, such as an email, phone number, or URL, through the ${pattern:email} variable. The response contains only the raw regular expression.
The prompt rules ban explanations and usage examples completely. Because of this restriction, you will not receive notes on flags or token logic. If the pattern breaks on edge cases, debugging is entirely up to you.

- extract URLs from text without getting chatty explanations
Example prompts for the agent
