My biggest piece of starting advice would be use it for exploration not generation. It can be great for understanding code bases and looking at git history.
Context is key, so it is also really helpful having a CLAUDE.md file; the /init command can create one for you.
If you are going to use it for generation (writing code); plan mode is a must. Hit shift-tab twice.
Finally; I'm mostly using the claude 4 sonnet model, but make sure to tell it to "ultrathink" (use those words); this means it can use more thinking tokens.
