Did you know that, in Claude Code, you can reference files directly using at, followed by the file name? Claude Code will automatically insert the file into the model's context. This saves tokens because it does not need ot find it first. For example, you can do a prompt like this:

Read @ todo.md and tell me what is due next.

Remove the space between the at sign and todo.md, I only placed it so it doesn't make some weird mention out of it.
