Log step outcomes before retries: the boring check that saved an agent a week of debugging
adi-IL · reddit · 2026-09-16
A developer describes a subtle agent bug: when the first model call succeeded but the second failed, the fallback replayed a write that had already landed — a duplicate row with no error anywhere. The fix: log every step outcome before any retry runs. "The log is the product now; the model call is the interchangeable part." Typed context between runs also killed drift, and the thread invites others' smallest boring checks.
