# Reference

Use this section when you already know what you're looking for: exact `swy` command syntax and flags, the MCP tool-to-CLI mapping, exit codes and error strings, and config file schemas. For task-oriented walkthroughs - installing the CLI, connecting an editor, writing your first policy - see the CLI and Policies sections instead.
