5 prompts to cut your Claude bill in half

Explain how I'm being charged when I use you. What actually costs money, what makes a conversation expensive, and what are the 3 habits that burn the most usage for someone like me who uses you for [what you mainly use Claude for]?

Look at how we've been working together and tell me honestly: what am I doing that wastes usage? Give me the top 3 changes ranked by how much they'd save.

Create a file in this folder called CLAUDE.md that keeps you efficient by default: short answers unless I ask for detail, no repeating whole files back to me, ask before big reads. Write it yourself, save it, and read it back to me.

Add this rule to the file: when I give you a big task, first tell me the cheapest way to do it. If a simpler approach gets 90% of the result, offer it before doing the expensive version.

Teach me the reset move: how do I know when this conversation has gotten heavy and I should start a fresh one instead of continuing? Give me a simple rule of thumb I'll actually remember, then add it to the file.
