The server demonstrates solid schema coverage with 31 tools, most with explicit descriptions and proper JSON Schema input validation. However, there are consistent gaps in parameter descriptions, limited error handling guidance, and insufficient context about tool relationships and composition. Tool naming is generally clear and action-oriented (search_, get_, list_), and descriptions are present for all tools. Output schemas are partially documented but lack explicit field-level descriptions. The server shows good use of regex patterns for law_id validation. Main weaknesses: many parameters lack descriptions (e.g., limit defaults without explanation of constraints), no recovery guidance in error scenarios, and minimal support for chaining tools through shared ID fields. The auxiliary tools (17-26) are less mature than legislation tools (1-9).

• Add explicit descriptions to all auxiliary table tools explaining their content and use cases. E.g., get_legal_ranges_table: 'Returns a reference table of Spanish legal/normative ranges (Ley, Real Decreto, Orden, Resolución, etc.). Use to understand the type hierarchy when analyzing laws.'
• Add min/max constraints to numeric parameters. E.g., 'limit': {'type': 'integer', 'description': 'Maximum results (1-100, default 20)', 'minimum': 1, 'maximum': 100}
• Add regex patterns to date parameters in schemas. E.g., 'date': {'type': 'string', 'pattern': '^\d{8}$', 'description': 'Date in YYYYMMDD format (e.g., 20240315)'}
• Document output schemas for each tool as a separate 'output_schema' field or in the description. Example: 'Returns: {"laws": [{"law_id": string, "title": string, "date": string}], "total": integer, "next_cursor": string|null}'
• Add error handling guidance to descriptions. E.g., get_consolidated_law: 'If the law_id format is invalid, the tool will return an error. Ensure law_id matches BOE-X-YYYY-NNNNN pattern.'
• For tools with overlapping functionality (e.g., get_consolidated_law, paginate_law_text, summarize_law_sections), add interdependencies in descriptions: 'Use summarize_law_sections() first for a quick overview; then paginate_law_text() or get_law_text_block() for detailed content.'
• Clarify pagination behavior in search tools. E.g., search_consolidated_legislation: 'Returns up to {limit} results. If more results exist, includes a next_cursor field in response for fetching the next page.'
