# — add a quick memory note
Starting your input with # saves it as a note to CLAUDE.md instead of sending it as a conversational message.
Mid-session, you'll sometimes hit on something worth remembering next time: a convention, a gotcha, a preference Claude should default to. Rather than context-switching to open CLAUDE.md and edit it by hand, prefixing a message with # saves it there directly.
This is the fast path for exactly the kind of detail that /init's auto-generated draft tends to miss — the reasoning behind a decision, not just the structure of the code. Small, frequent additions like this are usually what separates a genuinely useful CLAUDE.md from a stale one nobody maintains.
It's additive, not a replacement for reviewing the file occasionally — worth a skim now and then to prune anything that's stopped being true.
