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. Authority is attributed at both ends: "Seattle Fire Department is on the scene" and, in the all clear, "Seattle Fire Department determined there is no gas leak".
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
Present, 25 of 25. The location is exact, "Raitt Hall in the Quad", with a map link, and it is repeated in the all clear.
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. A protective instruction is given plainly: "Please avoid the area and building", later lifted by "All clear."
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. Every read agrees no consequence or severity is conveyed: the alert reports a smell, then states firefighters "determined there is no gas leak at Raitt Hall."
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.
