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.
Students, Faculty, and Staff: Due to the possibility of severe weather in Orange County and across Central North Carolina on Tuesday, June 23, the University is postponing the Alert Carolina test until Wednesday, June 24, between 5 p.m. and 7 p.m. During the system test, NO ACTION is required. If further changes to the timing of the test are required, the University will communicate any changes no later than 4 p.m. on Wednesday, June 24 via Alert Carolina. We test the Outdoor Emergency Sirens and messaging systems regularly throughout the year to make sure the equipment and notification processes work as planned, and to educate our community on what to do in the event of an emergency. During the test, anyone outside on or near campus will hear the sirens. The sirens are not designed to be heard inside a building or vehicle. The sirens will sound an alert tone along with a brief prerecorded voice message.

Final assessment
Present, unanimous at 25 of 25: the notice says "the University is postponing the Alert Carolina test" and promises further word "via Alert Carolina", naming both the institution and its branded channel.
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, 25 of 25 with no dissent: the postponement is attributed to "the possibility of severe weather in Orange County and across Central North Carolina", a named meteorological threat.
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, 25 of 25: the text geolocates both the weather, "Orange County and across Central North Carolina", and the sirens, audible to "anyone outside on or near campus".
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.

Guidanceabsent7/25
Final assessment
Absent by 7 of 25: the only direction given is "During the system test, NO ACTION is required", which withholds rather than supplies a protective step. A minority counted that line itself as an instruction.
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.

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, 0 of 25 voting present: severe weather appears purely as a scheduling reason, and nothing in the text says what that weather could do to people or property.
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.
