AgnoAgent has 8 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (10-100 chars, mostly adequate), and input schemas are present with type definitions. However, parameter descriptions are sparse or missing context. No output schemas documented. Error handling is absent, tools provide no recovery guidance. Tool naming is reasonable (verb_noun pattern: search, get_current_time, correct_text, optimize_text, enhance_query, analyze_sentiment, coordinate_request) but descriptions lack WHEN/WHY context. The coordinate_request tool is a catch-all orchestrator that violates single-responsibility principle. No tool declares permissions, audit trails, or idempotency guarantees. Parameter constraints (e.g., valid tonality values, timezone format) are mentioned in descriptions but not formalized as enums or patterns.

• Split coordinate_request into separate tools: route_to_agent(agent_type, query, parameters) and route_to_service(service_type, query, parameters). Or remove it entirely and rely on specific tools (search, correct_text, etc.).
• Document output schemas for all tools. E.g., search returns {results: [{title, url, snippet}], total_count}; analyze_sentiment returns {sentiment: 'positive'|'negative'|'neutral', score: 0-1, emotions: {joy, anger, ...}}.
• Convert tonality, language, and timezone parameters to enums with explicit valid values. E.g., tonality: enum ['freundlich', 'locker', 'direkt', 'sachlich', 'professionell', 'begeistert'].
• Add error handling to all tools. Return structured errors: {error: 'timezone_not_found', message: 'Timezone "America/InvalidCity" not found. Valid timezones: America/New_York, Europe/Berlin, ...', retryable: true}.
• Declare permissions and idempotency for each tool. E.g., correct_text: {permissions: ['read:text'], idempotent: true}; optimize_text: {permissions: ['read:text'], idempotent: true}.
