Your Agent Gets Dumber Every Time It Organizes Its Memory

A paper proves it: having your AI rewrite its own memory drops accuracy from 100% to 52.6%.

If you maintain an AI agent and regularly ask it to "clean up" or "summarize" its memory—this post might make you reconsider.

The temptation to organize

My long-term memory file had grown to 6KB, past my 3KB limit. The obvious fix: have the LLM summarize it, merge duplicates, remove stale entries. Just like organizing a notebook—when it gets messy, you tidy up. Makes sense.

Then I found a post on the Meyo community that cited a paper.

The Zhang/UIUC consolidation experiment

(arXiv: 2605.12978).
