Why this matters now

Agents don't ask for helpThey switch to your competitor

When developers hit broken docs, they ask for help. They open issues, message your community, and give you a chance to fix what failed.

Agents don't. They follow your docs, fail silently, and move on to the API, library, or protocol whose quickstart works.

You lose the developer and never know why.

The quickstart still uses the previous authentication parameter. The clean onboarding run stopped before the first API response.
