How the first alert is built
To check this alert, Claude Opus 5.5 (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 by near-unanimous agreement: the post cites "Police and fire are on scene" and points to "alert.uw.edu", identifying the university alert channel. One read dissented, saying no sender is explicitly named.
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
All 25 reads agree the hazard is named: the original post reports a "Reported shooting", a specific 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
Unanimous: the alert places the shooting "behind business on U Way NE near 42nd", a specific street location.
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.

Guidanceabsent0/25
Final assessment
All 25 reads agree no protective instruction is given. The updates describe the suspect, the victim, and responders on scene, but never tell recipients to avoid the area or take any action.
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
Unanimous: the thread is timestamped throughout, from "Sent at 6:56pm Thu" through "UPDATE at 7:46pm".
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.

Impactpresent25/25
Final assessment
All 25 reads find impact conveyed: the alert says "One injured" and that the injury "does not appear to be life threatening", stating the harm done and its severity.
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.
