Find the Claude Skills Quietly Eating Your Limit: The Hidden /skill-doctor Command
Every skill you install leaves a short note in Claude's context on every single message, even the ones you never use. Claude Code's /skill-doctor command shows what each skill costs and which ones never get used, so you can turn the dead weight off. How to run it, how to read it, and how to switch skills off
The people who never hit their Claude limit aren't using it better than you. A lot of them simply don't carry skills they never use.
Here's why it matters. For every skill you install, Claude Code keeps a short note in the conversation, the skill's name and description, so Claude knows the skill is there. That note is in context on every message. The full skill only loads when it's used, but the note never leaves. Install twenty skills, forget fifteen of them, and fifteen notes ride along with everything you send.
