Claude Desktop cheat sheet

Six phrases is all you need.

This page is for Claude Desktop — Anthropic's desktop app — which uses Mr. Mags through MCP (model context protocol). The phrases below are the most reliable triggers for the memory_save / memory_recall tools on that surface.

Using Mr. Mags on claude.ai, chatgpt.com, gemini.google.com, or a custom server? The browser extension handles capture automatically — bare facts get saved as you type, no special phrasing needed. This cheat sheet still helps but isn't required there.

To save something

"Remember that I teach biology."

"Remember that my third-period class has 28 students."

"Save this for later: [paragraph]."

Anything starting with "remember that" or "save" lands as a memory. Pick filenames in your head as you go — Claude will reuse them.

To check what's stored

"What do you know about me?"

"What do you know about my classes?"

"Show me everything you remember."

Claude will list filenames and pull up content as needed. The first one is the safest "is this thing working?" check.

To update something

"Update what you know about my schedule — third period is now AP Biology."

"Forget what I said about Sam — he transferred out."

"Update" overwrites. "Forget" deletes. Both are clean.

For your professional context (small, recurring stuff)

"I'm working on lesson plans for next week."

"This week's unit is cell biology."

Short context updates — Claude saves them as state, ready for any chat to reference.

If you're a teacher (one-time on first use)

"Set me up as a teacher."

"Load the teacher pack."

Claude loads 8 starter templates — lesson plan, rubric, parent email, IEP framing, classroom management, more — and sets a student-privacy rule (names default to initials in anything it writes). It's idempotent: running it again won't overwrite anything you've changed.


If something feels off

Claude doesn't seem to remember anything.
Quit Claude Desktop completely and reopen it. Mr. Mags only loads when Claude starts up.
Claude says "Mr. Mags isn't running."
Open Mr. Mags from your Applications folder. It lives in your menu bar (Mac) or system tray (Windows). The icon needs to be there.
I uninstalled Claude Desktop / moved Mr. Mags / something weird.
Reopen Mr. Mags. It self-heals — it'll re-write Claude Desktop's connection on every launch.
Where does my data live?
On your machine. Mac: ~/Library/Application Support/Mr. Mags/. Windows: %APPDATA%\Mr. Mags\. We don't collect it, so we don't have a copy.
