Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (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.

  • Sourceabsent0/25

    Final assessment

    No branded sender in the Drupal AVOID body. Majority 0/25.

    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.

    5. absent: I mark S absent (UO Seafoam AVOID, pass 5).
    6. absent: Downed power line is the hazard, not a sender (UO Seafoam AVOID, pass 6).

  • Hazardpresent25/25

    Final assessment

    Downed power line names a specific situation. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: Hazard is a downed power line, a specific named infrastructure failure. (UO Seafoam AVOID, pass 1).
    2. present: Downed power line names the threat. (UO Seafoam AVOID, pass 2).
    3. present: H is present via downed power line. (UO Seafoam AVOID, pass 3).
    4. present: I count H 1 because a downed power line is specified. (UO Seafoam AVOID, pass 4).
    5. present: Not a generic incident. (UO Seafoam AVOID, pass 5).
    6. present: I mark H present. (UO Seafoam AVOID, pass 6).
    7. present: Named hazard: downed power line. (UO Seafoam AVOID, pass 7).
    8. present: H holds. (UO Seafoam AVOID, pass 8).
    9. present: The body names the downed power line. (UO Seafoam AVOID, pass 9).
    10. present: I score H 1. (UO Seafoam AVOID, pass 10).
    11. present: A downed power line is a specific threat. (UO Seafoam AVOID, pass 11).
    12. present: Hazard element is satisfied by the fallen line. (UO Seafoam AVOID, pass 12).
    13. present: I count H present. (UO Seafoam AVOID, pass 13).
    14. present: The what is a downed power line on a campus road. (UO Seafoam AVOID, pass 14).
    15. present: H verdict 1: the hazard is explicit. (UO Seafoam AVOID, pass 15).
    16. present: Power line down is a named situation. (UO Seafoam AVOID, pass 16).
    17. present: I read a concrete hazard. (UO Seafoam AVOID, pass 17).
    18. present: The text is not a weather watch; it names the line. (UO Seafoam AVOID, pass 18).
    19. present: H remains present on this short AVOID. (UO Seafoam AVOID, pass 19).
    20. present: I treat downed power line as the hazard noun. (UO Seafoam AVOID, pass 20).
    21. present: Hazard is specific, not a blank incident. (UO Seafoam AVOID, pass 21).
    22. present: H passes the named-threat test. (UO Seafoam AVOID, pass 22).
    23. present: I leave H at 1 (UO Seafoam AVOID, pass 23).
    24. present: The Drupal AVOID states the downed line as the reason. (UO Seafoam AVOID, pass 24).
    25. present: H is present (UO Seafoam AVOID, pass 25).
  • Locationpresent25/25

    Final assessment

    Seafoam Lane is a named road. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: Location is Seafoam Lane, a named road (UO Seafoam AVOID, pass 1).
    2. present: Seafoam Lane is a specific place (UO Seafoam AVOID, pass 2).
    3. present: L is present (UO Seafoam AVOID, pass 3).
    4. present: I count L 1 (UO Seafoam AVOID, pass 4).
    5. present: Named street satisfies location (UO Seafoam AVOID, pass 5).
    6. present: I mark L present (UO Seafoam AVOID, pass 6).
    7. present: Where: Seafoam Lane (UO Seafoam AVOID, pass 7).
    8. present: L holds (UO Seafoam AVOID, pass 8).
    9. present: I score L 1 (UO Seafoam AVOID, pass 9).
    10. present: A named lane is a place (UO Seafoam AVOID, pass 10).
    11. present: Location element is satisfied (UO Seafoam AVOID, pass 11).
    12. present: Seafoam Lane is not a campus-wide vague area (UO Seafoam AVOID, pass 12).
    13. present: I count L present (UO Seafoam AVOID, pass 13).
    14. present: The where is Seafoam Lane at OIMB as named in the body (UO Seafoam AVOID, pass 14).
    15. present: L verdict 1: a street name is enough (UO Seafoam AVOID, pass 15).
    16. present: The avoid target is a specific lane (UO Seafoam AVOID, pass 16).
    17. present: I read a concrete location (UO Seafoam AVOID, pass 17).
    18. present: The text names Seafoam Lane twice-worth as the place (UO Seafoam AVOID, pass 18).
    19. present: L remains present on this short AVOID (UO Seafoam AVOID, pass 19).
    20. present: I treat Seafoam Lane as the location noun (UO Seafoam AVOID, pass 20).
    21. present: Location is specific, not campus-at-large (UO Seafoam AVOID, pass 21).
    22. present: L passes the named-place test (UO Seafoam AVOID, pass 22).
    23. present: I leave L at 1 (UO Seafoam AVOID, pass 23).
    24. present: The Drupal AVOID states the lane to avoid (UO Seafoam AVOID, pass 24).
    25. present: L is present (UO Seafoam AVOID, pass 25).
  • Guidancepresent25/25

    Final assessment

    AVOID is a protective instruction. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: Guidance is AVOID, a protective instruction (UO Seafoam AVOID, pass 1).
    2. present: AVOID tells recipients to stay away (UO Seafoam AVOID, pass 2).
    3. present: G is present (UO Seafoam AVOID, pass 3).
    4. present: I count G 1 (UO Seafoam AVOID, pass 4).
    5. present: The text instructs people to avoid the lane (UO Seafoam AVOID, pass 5).
    6. present: I mark G present (UO Seafoam AVOID, pass 6).
    7. present: Avoid-area guidance is in the rubric (UO Seafoam AVOID, pass 7).
    8. present: G holds (UO Seafoam AVOID, pass 8).
    9. present: I score G 1 (UO Seafoam AVOID, pass 9).
    10. present: An imperative AVOID is guidance (UO Seafoam AVOID, pass 10).
    11. present: Guidance element is satisfied (UO Seafoam AVOID, pass 11).
    12. present: Stay-away instruction is explicit (UO Seafoam AVOID, pass 12).
    13. present: I count G present (UO Seafoam AVOID, pass 13).
    14. present: The how is AVOID Seafoam Lane (UO Seafoam AVOID, pass 14).
    15. present: G verdict 1: AVOID is protective (UO Seafoam AVOID, pass 15).
    16. present: Recipients are told to keep off the lane (UO Seafoam AVOID, pass 16).
    17. present: I read a concrete instruction (UO Seafoam AVOID, pass 17).
    18. present: The text is not informational-only; it orders avoidance (UO Seafoam AVOID, pass 18).
    19. present: G remains present on this short AVOID (UO Seafoam AVOID, pass 19).
    20. present: I treat AVOID as the guidance verb (UO Seafoam AVOID, pass 20).
    21. present: Guidance is specific, not a status-only note (UO Seafoam AVOID, pass 21).
    22. present: G passes the protective-action test (UO Seafoam AVOID, pass 22).
    23. present: I leave G at 1 (UO Seafoam AVOID, pass 23).
    24. present: The Drupal AVOID opens with the stay-away command (UO Seafoam AVOID, pass 24).
    25. present: G is present (UO Seafoam AVOID, pass 25).
  • Timepresent25/25

    Final assessment

    10/21/25 7:46 AM is a date and clock. Majority 25/25.

    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.

    See all 25 individual reads
    1. present: 10/21/25 7:46 AM is an explicit date and clock time (UO Seafoam AVOID, pass 1).
    2. present: T is present via 10/21/25 and 7:46 AM (UO Seafoam AVOID, pass 2).
    3. present: I count T 1 (UO Seafoam AVOID, pass 3).

    7. present: T holds (UO Seafoam AVOID, pass 7).
    8. present: I score T 1 (UO Seafoam AVOID, pass 8).

    11. present: T is present on this AVOID (UO Seafoam AVOID, pass 11).
    12. present: The stamp is a real clock, not a vague today (UO Seafoam AVOID, pass 12).
    13. present: I count T present (UO Seafoam AVOID, pass 13).

    17. present: I read an explicit timestamp (UO Seafoam AVOID, pass 17).
    18. present: The first line is a dated clock (UO Seafoam AVOID, pass 18).
    19. present: T remains present on this short AVOID (UO Seafoam AVOID, pass 19).
    20. present: I treat 7:46 AM as the time noun (UO Seafoam AVOID, pass 20).
    21. present: Time is specific, not a day-only label (UO Seafoam AVOID, pass 21).
    22. present: T passes the date-and-clock test (UO Seafoam AVOID, pass 22).

  • Impactabsent0/25

    Final assessment

    No explicit consequence in the first-burst AVOID. Majority 0/25.

    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.

    See all 25 individual reads
    1. absent: Impact is absent: no injury or severity is stated (UO Seafoam AVOID, pass 1).
    2. absent: Downed power line names the situation, not a harm clause (UO Seafoam AVOID, pass 2).
    3. absent: I code I 0 (UO Seafoam AVOID, pass 3).
    4. absent: AVOID is guidance not impact (UO Seafoam AVOID, pass 4).
    5. absent: I mark I absent (UO Seafoam AVOID, pass 5).
    6. absent: The rubric example list is not matched (UO Seafoam AVOID, pass 6).
    7. absent: I find no harm sentence (UO Seafoam AVOID, pass 7).
    8. absent: Impact fails (UO Seafoam AVOID, pass 8).
    9. absent: I score I 0 (UO Seafoam AVOID, pass 9).
    10. absent: Naming the downed line is the hazard, not impact (UO Seafoam AVOID, pass 10).
    11. absent: I is 0 on this AVOID (UO Seafoam AVOID, pass 11).
    12. absent: No injuries, deaths, or damage totals appear (UO Seafoam AVOID, pass 12).
    13. absent: I do not count I (UO Seafoam AVOID, pass 13).
    14. absent: Impact identity is missing from the flattened Drupal body (UO Seafoam AVOID, pass 14).
    15. absent: I verdict 0: no consequence clause (UO Seafoam AVOID, pass 15).
    16. absent: Nothing here functions as a named harm (UO Seafoam AVOID, pass 16).
    17. absent: I read no impact element (UO Seafoam AVOID, pass 17).
    18. absent: The product never says anyone was hurt (UO Seafoam AVOID, pass 18).
    19. absent: I remains absent on this short AVOID (UO Seafoam AVOID, pass 19).
    20. absent: I treat the timestamp as time, not an impact (UO Seafoam AVOID, pass 20).
