Agent Saved 80,000 Characters of Lessons — the Next Agent Never Read Them

A Reddit user describes how their team auto-saved reviewer feedback for coding agents, accumulating 20 entries (80k characters) in 12 hours — only to find the next agent never read that field, only the coding standards and pinned notes. They had built the writing side of agent memory but no path for lessons to influence the next run. Fix: disable auto-append by default, make rule extraction and task linking separate steps, and ask where/when info is read and how to verify it prevents repeat mistakes. The real work, they conclude, isn't saving conversations but deciding what should affect the next decision.
