Example Prompts

Basic secret sharing:

Share this API key securely: sk-abc123xyz

With custom expiration:

Create a secret link for the password hunter2 that expires in 1 hour

Share this token ghp_xxxxxxxxxxxx as a secret that expires in 10 minutes

With custom max reads:

Create a secret for my-db-password that can be read up to 3 times

Share this SSH key passphrase correct-horse-battery-staple so that 5 people can read it

Combining expiration and max reads:

Create a secret link for postgres://user:pass@host/db that expires in 2 hours and can only be read twice

Share the credentials admin / P@ssw0rd! as a secret valid for 30 minutes and readable only once
