4 Agent Failure Modes: Writing State to Files is the Cure
sujingshen · x · 2026-07-03
The author summarizes four typical ways Agents fail: ① Context explosion leading to half-baked outputs; ② Declaring the job done upon seeing code, despite only completing 30%; ③ Marking completion after passing unit tests when end-to-end fails entirely; ④ Spending 20 minutes guessing the current state on every startup. The universal antidote to all these failures is the same: write states into files and let the Agent read them instead of relying on its memory.
