Three tools with complete input schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (search_, get_). Descriptions are present but generic (avg ~120 chars, below 194-char baseline). Parameters lack individual descriptions in schema, LLMs cannot infer what 'qf' means from the name alone. Output schemas are not formally documented; responses are inferred from code. No error handling guidance, no pagination metadata, no per-item success/failure reporting. Composition is reasonable (three distinct concerns), but tools lack the polish expected of production-grade agents.

• Add individual descriptions to all schema parameters. For search_europeana, add 'qf': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Query filters as key:value pairs (e.g., TYPE:IMAGE, COUNTRY:france). See get_available_filters() for valid keys and values.'}
• Document output schemas explicitly. Define the structure of items returned by search_europeana: each item has title (string), id (string), type (string), year (string), creator (string), country (string), provider (string), thumbnail (string|null), link (string).
• Add error handling with recovery hints. Wrap httpx calls in try/except; catch HTTPStatusError and return structured errors like {'error': 'API_KEY_INVALID', 'message': 'EUROPEANA_API_KEY is missing or invalid. Set it as an environment variable.', 'retryable': false}.
• Enhance search_europeana to return pagination metadata: 'totalResults', 'itemsReturned', 'nextStart' (if more results exist), 'hasMore' (boolean). This enables LLMs to iterate without guessing.
• Expand get_available_filters description to ~100 chars: 'Retrieve available filter categories and example values for Europeana searches. Call this first to discover valid TYPE, COUNTRY, LANGUAGE, and other filter options before calling search_europeana.'
