Fill this in from your own project, not from a demo. The readings only teach you something when the numbers are yours.
Your four readings
Run these in the project you shipped, and write down what came back.
| Command | What it tells you | Your reading |
|---|---|---|
/usage | What the work in this session has cost | |
/context | How full the conversation has become, and what is taking up the space | |
/model | Which brain you used, and what else you could have picked | |
/memory | What the project remembers between sessions |
Date you took these readings
The five you reach for day to day
| Command | What it does | When you reach for it |
|---|---|---|
/clear | Wipes the conversation so the next task starts with nothing behind it | Every time you start something unrelated to what you just did |
/usage | The meter | Before a big task and again after it, so you learn what that kind of work costs |
/context | How full the room is | Any time a search or a large file read might have poured into the conversation |
/model | Switches which brain is working | Deep model for planning, faster one for carrying out a settled plan |
Esc Esc | Opens the rewind menu on an empty input line | When Claude did something you did not ask for and you want to stand at an earlier point |
The rest of the shelf
Waiting for the day you need them, and not before.
| Command | What it does |
|---|---|
/help | Lists every command available to you |
/status | What Claude currently knows about your setup, the model, the project, the account |
/compact | Squeezes the conversation into a summary and keeps working from that. Add an instruction after it, like keep the database decisions and drop the styling chatter, and it keeps what you named instead of guessing |
/config | Where your preferences live |
/memory | The project's long-term notes |
/effort | How hard Claude thinks before it answers |
/btw | A side question that never enters the history Claude carries forward. Try it once in your own setup before you lean on it |
/export | Lifts a whole conversation out as a file, to keep or to share |
/rewind | The typed version of Escape twice |
/desktop | Hands the current terminal session over to the desktop app, history intact |
/add-dir | Adds another folder alongside the one you started in |
Clear or compact
Both free up space. Compact is crushing the trash down so it takes less room in the can. Clear is carrying the bag out to the curb and starting with an empty can.
A summary quietly drops details you did not know you needed, so keeping the important things in a document you control is the safer habit. Lean on clear, and steer compact when you do use it.
