How the first alert is built
To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

Final assessment
Majority (16 of 25) find no sender or named authority; "Follow police instructions" references responders, not the issuer, so the source is absent.
Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

Locationpresent25/25
Final assessment
Unanimous: it cites "Arts & Letters, Boca", a specific place, so location is present.
Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

Guidancepresent25/25
Final assessment
All 25 reads agree it instructs "Remain alert. Seek shelter in secure location", protective actions, so guidance is present.
The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

Impactpresent18/25
Final assessment
Present by an 18 to 7 majority: it reports an armed intruder or shooter and to seek shelter in a secure location, with the armed shooter conveying lethal danger to people; dissenters see only hazard naming.
What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
