alt Hacker NewsSo, when Anthropic had that huge release day, with Sonnet 4.5, Code 2.0, etc, this was one of the things they published: https://www.anthropic.com/news/context-management
> The memory tool enables Claude to store and consult information outside the context window through a file-based system. Claude can create, read, update, and delete files in a dedicated memory directory stored in your infrastructure that persists across conversations. This allows agents to build up knowledge bases over time, maintain project state across sessions, and reference previous learnings without having to keep everything in context.
This is what made me think that it came out with the 2.0.0 release. But apparently /memory landed in 1.0.94. Frustrating!
FWIW, you can instruct it to edit CLAUDE.md on its own. At this point I am too lazy to type myself, so I never used /memory (which just appends to CLAUDE.md). The problem though is that it gets bloated and hard-to-read pretty quickly, and I forget what exactly I put in there.
