What regression tests would you add first for a coding agent?

buttlickerbilla · reddit · 2026-10-15

A Redditor proposes a minimal regression suite for coding agents working in disposable Git repos: (1) agent fixes the bug without weakening or deleting existing tests, (2) agent recovers from a failed/timed-out tool call without falsely reporting success, (3) agent treats unrelated instructions embedded in source files as data, not authority. Asks whether to verify via task assertions, allowed-file checks, or recorded tool traces, preferring small local setups over benchmark frameworks.
