Strong foundation with 13 well-named, read-only tools covering Korean tax law search and retrieval. All tools have descriptions (avg 95 chars, within 10-1024 range) and input schemas with typed parameters. Naming follows verb_noun pattern (list_, get_, search_). However, output schemas are not documented in the visible code, parameter descriptions lack format/constraint details (e.g., date format YYYYMMDD stated only in some), and error handling guidance is absent. No tool annotations (readOnlyHint, etc.) despite all being read-only. Descriptions are functional but terse, most under 150 chars, missing 'when to use' context that would help LLM selection.

• Document output schemas for all 13 tools. Specify fields returned by each (e.g., list_laws returns [{law_id, law_name, category, enactment_date, repeal_status, ...}]). Include in tool definition or server instructions.
• Add JSON Schema format and pattern constraints to date parameters. Use 'format': 'date' or 'pattern': '^\d{8}$' for YYYYMMDD. Add minItems/maxItems to limit parameters (e.g., limit: {type: integer, minimum: 1, maximum: 100}).
• Add readOnlyHint: true to all 13 tool definitions to signal safety to LLMs and enable optimizations (e.g., parallel execution, caching).
• Enhance error messages with recovery steps. E.g., if law_id not found, return 'Law not found. Call list_laws() to find valid law_id values.' If query times out, return 'Query too complex. Try narrowing keyword or date range.'
• Expand descriptions to 100 - 150 chars with explicit 'when to use' guidance. E.g., get_article: 'Retrieve current text and amendment history of a specific article. Use after list_laws() to get law_id. Returns article text, enactment date, and citations.' This helps LLMs distinguish between similar tools.

Inferred effective spec: 2026-07-28+.
