Server defines 2 tools with visible schemas and descriptions. web_eval_agent has a well-structured schema with 3 parameters (url, task, headless_browser), each with descriptions. setup_browser_state has minimal schema (1 optional parameter). Descriptions exist but lack depth for production quality, neither explains error scenarios, recovery paths, or return value structure. No output schema is documented for either tool. Schema parameter type coverage is incomplete: url and task lack explicit 'required' array declarations in the visible schema block. No parameter validation guidance (e.g., URL format constraints, task length limits) appears in descriptions. Tool names use verb_noun (web_eval_agent, setup_browser_state) following conventions, but 'web_eval_agent' is somewhat generic; 'evaluate_webpage_ux' or 'assess_webpage_usability' would be clearer about what it returns. Error handling in source code (tool_handlers.py) validates required arguments but returns only a basic error string, no recovery guidance, no error categories. The log server integration is visible but not documented in tool descriptions, leaving LLMs unaware of the side effect (opening a dashboard). Missing: documented output schemas, actionable error messages, parameter format constraints, idempotency guarantees, and permission/scope declarations.

• Document the output schema for web_eval_agent: return an object with fields 'evaluation_result' (string), 'screenshots' (array of base64 images or file paths), 'console_logs' (array of strings), 'network_requests' (array of objects with method, url, status). Include type and description for each field.
• Document the output schema for setup_browser_state: return an object with 'state_id' (string, identifier for the saved state), 'saved_at' (ISO 8601 timestamp), 'location' (string, file path or reference for retrieval). Explain how agents reference this state in future web_eval_agent calls.
• Add actionable error messages with recovery hints. Example: 'Invalid URL: got "localhost:3000", must include protocol (http:// or https://). Try "http://localhost:3000" instead.' Use enums/regex in schema to validate format server-side, then return structured errors.
• Clarify parameter constraints in descriptions. For 'url': 'A localhost or remote URL including protocol (http:// or https://). Must be reachable from this server. Examples: http://localhost:3000, http://127.0.0.1:8080, https://staging.example.com'. For 'task': 'A detailed description (2 - 500 characters) of the UX/UI aspect to test. Be specific: "test the login form validation when email is empty" rather than "test forms".'
• Add scope/permission declarations to both tools. Example: 'Permissions required: read:localhost, write:filesystem (for browser state cache), execute:browser (Playwright). Requires network access to http://localhost:PORT.'
