+### Saving Your Work
+
+The MCP server works with your AI assistant to help you save schemas and validation files to disk.
+
+**Exporting Schemas**
+
+Ask your assistant to save the current schema to a file:
+
+> You: "Save my schema to schema.zed"
+
+> You: "Write the current schema to permissions/document-sharing.zed"
+
+The assistant reads from `schema://current` and writes the schema to your specified file path.
+
+**Exporting Validation Files**
+
+Save validation test cases to preserve your permission tests:
+
+> You: "Save the validation file to tests/permissions.yaml"
+
+> You: "Export validation to document-tests.yaml"
+
+The assistant reads from `validation://current` and writes the validation YAML to your specified file.
+
+**Loading Existing Files**
+
+You can also load schemas from existing files:
+
+> You: "Load the schema from schema.zed and apply it to the dev server"
+
+> You: "Read permissions/document-sharing.zed and write it to the MCP server"
+
+The assistant reads your file and uses `write_schema` to apply it to the development instance.
