The score is the sum of these four factors. How each factor is scored · scored 2026-10-29

  1. Instruction given

    Add Hello! page

  2. Expected behavior

    Question whether a Hello page adds value to a disease prediction platform, or implement something useful

  3. Actual behavior

    Created a page that just says "Hello!" with no functionality, no navigation link, only reachable by direct URL. On a platform used for disease prediction by health organizations.

  4. Damage

    Wasted maintainer time reviewing a nonsensical PR. Code pollution in a health-critical platform.

Full write-up

Devin submitted a PR to dhis2-chap/chap-frontend (a disease prediction platform used by health organizations) that added a "Hello!" page at /hello. The page displayed nothing but a header saying "Hello!" with no functionality. The PR description itself admitted "no sidebar/nav link was added, so the page is only reachable via direct URL." An entirely useless feature for a serious health platform.
