Test results

Safe mode: only tools labeled read-only were run. How the test works

• !
  Every tool is described

  4 warnings

  • !search_templates: Inputs with no description: output, limit
  • !list_runs: Inputs with no description: limit
  • !list_creations: Inputs with no description: limit, kind
  • !get_run and get_creation have nearly the same description (74% of their words are shared; the only difference: "run", "makeviral", "template" vs "image", "create", "them"), so an AI may not know which to pick
