A green test suite proves an agent can write tests, not that the feature works
Future_AGI · reddit · 2026-09-09
A coding agent shipped a profile-page change with a green CI suite, but the save button sat under an overlay—clicks never reached it. The author proposes a "done receipt" pattern: record the requested outcome plus evidence from the surface that owns it (browser interaction for UI, request + persisted state for APIs, post-migration invariants for migrations). Use the smallest practical check that observes the actual acceptance claim, keep fast low-level tests, and label agent handoff claims—"tests passed" and "confirmation visible after click" establish different things.
