This server exhibits critical deficiencies across naming, descriptions, parameter validation, and schema completeness. Tools are defined with names that lack action verbs (gmail-template, google-calendar, knowledge-base, api-caller), making intent ambiguous to LLMs. Parameter descriptions exist but are minimal and generic. Most critically, input schemas lack proper JSON Schema structure with type definitions, they are defined as simple string/object mappings in tool-routing-agent.ts without formal types, descriptions per parameter, or constraints. Output schemas are entirely undocumented. Error handling is minimal with no recovery guidance. The server shows no evidence of following the 54 Agentic Tool Patterns.

• Rename tools with action verbs: 'gmail-template' → 'create_email_draft', 'google-calendar' → 'create_calendar_event', 'knowledge-base' → 'search_knowledge_base', 'api-caller' → remove or split into domain-specific tools (e.g., 'query_external_api') with an allow-list.
• Expand tool descriptions to 150 - 250 chars, each answering: What does it do? When should the LLM call it? What does it return? Prerequisites? Example: 'Creates a Gmail draft without sending. Use when the user wants to review before sending. Returns draft_id and draft_url. Requires Gmail authentication.'
• Add per-parameter descriptions: instead of {'to': 'string'}, use {'to': {'type': 'string', 'description': 'Recipient email address (valid format required). Example: [email protected]'}}. Include constraints: max length, format, allowed values.
• Document all output schemas with field names, types, and descriptions. Example: create_calendar_event returns {'event_id': 'string (unique identifier)', 'event_url': 'string (shareable link)', 'created_at': 'ISO 8601 timestamp'}.
• Add input validation and error messages: 'Invalid email format: must be [email protected]'; 'Invalid time range: start must be before end'; 'Method must be one of: GET, POST, PUT, DELETE'.
• Remove or redesign 'api-caller' to be domain-specific. If generic HTTP calling is needed, require an explicit allow-list of approved URLs, enforce authentication headers, and validate request payloads against expected schemas.
• Implement recovery guidance in error responses: 'Email address not found. Try search_users(name) first to find the correct address.' instead of a bare error.
