How the first alert is built
To check this alert, Claude Opus 5 (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
Present, 25 of 25. The post names UW policing throughout, with "UWPD is continuing its investigation" and a callback number, and it directs readers to "alert.uw.edu".
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.

Hazardpresent25/25
Final assessment

Locationpresent25/25
Final assessment
Present, 25 of 25. The scene is pinned to "Triangle Garage near UW Medical Center", with the suspect "last seen at the bus stop on the south side of NE Pacific St."
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
Present, 25 of 25. Recipients are told to "Avoid area", and if they see the suspect to not "attempt to make contact and instead call 9-1-1."
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.

Impactpresent23/25
Final assessment
Present, 23 of 25. The warning that "The suspect is armed" and that readers should not make contact conveys the danger of an encounter; two reads wanted an explicit statement of harm.
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.
