  • Engineer — Learn: This research reveals that for 30–33% of Microsoft Graph tasks and ~3% of Google API tasks, no single minimal permission set exists — grants form incomparable antichains. Engineers designing agent authorization systems should factor in that least-privilege tooling and permission solvers may be unsolvable by design for a significant share of tasks, meaning automated minimal-grant selection is not a reliable safety net.
