Eight tools with clear verb-noun naming (list_, get_, compare_, search_) and comprehensive descriptions (100-250 chars each). All tools have documented input schemas with types and descriptions. Output schemas are well-structured with metadata fields. Error handling returns actionable guidance ('Call list_indicators to see valid names'). Main gaps: no enum constraints on category/period parameters, no explicit output schema documentation in docstrings, and missing parameter validation details (e.g., date format YYYY-MM-DD stated in description but not in schema format field).

• Add enum constraints to 'category' parameter in list_indicators: {"enum": ["inflation", "employment", "growth", "housing", "consumer", "rates", "stress", "markets", "fiscal"]}
• Add enum constraint to 'period' parameter in compare_indicators: {"enum": ["1y", "2y", "5y", "10y"]}
• Document output schemas in each tool's docstring. Example: 'Returns: {"name": str, "title": str, "category": str, "units": str, "frequency": str, "series_id": str, "source": str, "latest_value": float, "change_1m": float, "change_1y": float, ...}'
• Add 'format': 'date' to start/end parameters in get_history schema to enforce YYYY-MM-DD at parse time, not runtime.
• Add offset/limit pagination to list_indicators and release_calendar. Return total count and next_offset to enable multi-page discovery of large indicator catalogs.
