Token

A small piece of text (roughly a short word) used to measure how much Claude reads and writes, and so the cost. Careful: “token” also means an access password.

You’ll also find it as: tokens

How it appears in the course

/cost — shows how many tokens (and therefore how much money or how much of your limit) you’ve used.
What are the main slash commands? · Module 00, Installation and first steps · free
“Look in src/auth/” — where to search. “The token refresh” is the part that automatically renews the user’s “entry ticket”.
What does a good message look like? · Module 01, How to talk to Claude · free
Secrets and tokens (passwords and access keys). CLAUDE.md usually ends up in git, so others can see it.
What goes in CLAUDE.md, and what stays out? · Module 02, CLAUDE.md: your project’s memory
