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.

Sourcepresent25/25
Final assessment
Present, unanimously. The HAWK ALERT tag identifies the university system and the NWS is named as the issuing agency.
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
Present, unanimously. The message names a tornado warning directly.
What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

Locationpresent25/25
Final assessment
Present, unanimously. Johnson County is stated as the warned area.
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, unanimously. Seek immediate shelter is an unambiguous protective instruction, reinforced by a link for further information.
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.

Timepresent25/25
Final assessment
Present, unanimously. The warning is valid until 1 pm, and the word immediate conveys urgency.
When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

Impactabsent0/25
Final assessment
Absent, unanimously. The alert names the tornado warning but never describes what the tornado could do or how severe it may be.
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.
