Why AI-built apps get this
Response headers are written by nobody. Your framework does not add them, your builder does not add them, and your host adds one or two at most. They are the clearest example of a gap that no tool closes on your behalf, which is why almost every app built by a prompt ships without them.
What it affects
Browsers remember to use https for this domain on later visits.
What the evidence line looks like
GET https://example.com returned no strict-transport-security header
Every finding on a result carries a line like this one: the request that was made and the answer that came back. You can run the same request yourself and get the same answer, which is the point.
The fix
Nothing to change here.
Prompt for your coding agent
Keep the Strict-Transport-Security header in place.
A result gives you this prompt written for your builder, in its own dialect, and a batch prompt that carries every fix at once.
