## How to run a command

When the user invokes a command:
1. Load the matching reference file using the Read tool
2. Follow the instructions in that reference exactly
3. If no command is specified:
   - With a URL → default to `audit`
   - With a business type → default to `plan`
   - Otherwise ask: "Would you like a full audit, a single-page analysis, or an SEO strategy?"
