Last week, I was refactoring a Go backend project. It spanned three days, four sessions, and roughly a dozen /compact operations.
The task itself wasn’t particularly complex, but one issue kept bothering me: every time I restarted the command-line session the next day, Claude would redo the modules I had already refactored.
This has nothing to do with the model “getting dumber.” It’s simply that the working memory was lost.
Later, I reviewed the Claude Code documentation again, combined it with my own hands-on experience, and wrote this article.
Specifically, I want to talk about the long-term task memory problem in AI coding agents — from the most basic file-based approach to more engineered infrastructure solutions.
I’ll cover the trade-offs of each path and what we should do at this point in time to handle memory for large, cross-session projects.
