• Provide the actual tool registration code from 'playwright/lib/mcp/browser/tools' showing schema definitions, descriptions, and parameter types.
• Add comprehensive descriptions to both tools explaining WHAT they do, WHEN to use them, and WHAT they return. Target 50-200 characters per description.
• Define complete JSON Schema for each tool's input parameters with types, constraints, and per-parameter descriptions. Example: { url: { type: 'string', description: 'Full HTTP(S) URL to navigate to' } }.
• Document output schemas showing all fields returned from browser_navigate and browser_click responses.
• Implement error handling that returns structured, actionable messages. E.g., 'Navigation timeout after 30s to https://example.com, browser may be unresponsive. Try check_browser_status() or reconnect.' instead of raw errors.
• Add parameter descriptions for both tools explaining valid input ranges, formats, and defaults. For browser_click: 'Selector must be a valid CSS selector string (e.g., "button.submit", "[data-testid=login]").'
• Implement idempotency hints or confirmation patterns for destructive browser actions (navigate, click) to prevent accidental re-execution.
• Document which parameters are required vs optional and what smart defaults apply.
