 ## Code Style Guidelines

 - Use Tailwind CSS for styling in the web app
 - Keep components small and focused on a single responsibility
 
+## Tool Input Parameter Handling
+
+When implementing or modifying tool input parameter handling in the Inspector:
+
+- **Omit optional fields with empty values** - When processing form inputs, omit empty strings or null values for optional parameters, UNLESS the field has an explicit default value in the schema that matches the current value
+- **Preserve explicit default values** - If a field schema contains an explicit default (e.g., `default: null`), and the current value matches that default, include it in the request. This is a meaningful value the tool expects
+- **Always include required fields** - Preserve required field values even when empty, allowing the MCP server to validate and return appropriate error messages
+- **Defer deep validation to the server** - Implement basic field presence checking in the Inspector client, but rely on the MCP server for parameter validation according to its schema
+
+These guidelines maintain clean parameter passing and proper separation of concerns between the Inspector client and MCP servers.
+
 ## Project Organization
 
 The project is organized as a monorepo with workspaces:
 
-- `web/`: Web application (Vite, TypeScript, Tailwind)
+- `clients/web/`: Web application (Vite, TypeScript, Tailwind)
 - `core/`: Core shared code used by web, CLI, and TUI
-- `cli/`: Command-line interface for testing and invoking MCP server methods directly
-- `tui/`: Terminal user interface
+- `clients/cli/`: Command-line interface for testing and invoking MCP server methods directly
+- `clients/tui/`: Terminal user interface
 - `test-servers/`: Composable MCP test servers, fixtures, and harness
