Tool definitions are inferred from test files rather than explicit registration code. No input schemas visible in source, all tools scored 0 for schema. Descriptions are present but generic (10-50 chars), falling below the 20-char minimum for meaningful scoring. No parameter descriptions found. No output schemas documented. No error handling guidance. Tools lack verb-noun clarity (e.g., 'session_list' vs 'list_sessions'). This server does not meet baseline quality for production agent use.

• Add explicit tool registration with full JSON Schema input definitions. Include type, description, and constraints for every parameter. Example: 'action' should be enum: ['get', 'set', 'clear'] with description 'Cookie operation: get retrieves all cookies, set adds/updates cookies, clear removes all cookies.'
• Expand tool descriptions to 50-200 characters. Include WHEN to use (e.g., 'Call before browser_evaluate to ensure page is loaded'), prerequisites, and what the tool returns. Example: 'Navigate browser to URL with security checks. Validates URL format and blocks file:// and javascript: schemes. Returns navigation status and final URL after redirects.'
• Document output schemas for all tools. Specify returned fields, types, and pagination support. Example: session_list should return {sessions: [{id: string, name: string, created_at: ISO8601}], total: number}.
• Add parameter descriptions for all inputs. Clarify enums, ranges, and formats. Example: browser_cookies 'action' param should state 'One of: get (retrieve all cookies), set (add/update cookies array), clear (delete all cookies).'
• Implement error handling guidance. Return actionable errors with recovery hints. Example: 'URL validation failed: invalid scheme. Use http://, https://, or data: URLs. Blocked schemes: file://, javascript://, data:image.'.
