BUILT TO ASK FIRST

It's built to wait for your OK in Langfuse.

When a job ends in “Create a comment”, it does the work, and is built to stop with it ready. You see exactly what it wrote and where it goes, then Send, Edit or Deny.

It works in Langfuse signed in as you. If it hits a sign-in, you sign in yourself: it's built not to type your passwords or card numbers.
