Three well-named, read-only tools with clear descriptions and proper input schemas. All tools start with action verbs (get_, search, cite_affected). Descriptions are detailed (150 - 250 chars) and explain what each tool does and when to use it. Input schemas use Zod with type declarations and parameter descriptions. However, output schemas are not formally documented, responses are free-text strings rather than structured objects. Error handling returns text messages but lacks categorization (retryable vs. fatal). No tool annotations (readOnlyHint, idempotentHint) despite all being read-only. Missing pagination for search results (limit capped at 25 but no offset/cursor). Overall solid foundation with room for structured output and error guidance.

• Convert all tool responses from free-text strings to structured JSON objects. E.g., get_section should return {cite, caption, url, text, history} as separate fields. Document the output schema in tool registration.
• Add readOnlyHint and idempotentHint annotations to all three tools via the tool registration API. This signals to LLMs that these tools are safe to call repeatedly without side effects.
• Enhance error responses with error codes and recovery guidance. Return {error: 'not_found', message: '...', retryable: false, suggestion: 'Try search_cites() first'} instead of plain text.
• Add offset/cursor pagination to search tool. Accept optional 'offset' parameter (default 0) and return {cites: [...], total: N, offset: 0, limit: 10, has_more: true} so agents can fetch all results.
• Document cite format constraints in parameter descriptions. E.g., 'RCW cite in format CHAPTER.SECTION (e.g., 9A.36.021) or CHAPTER (e.g., 9A.36)' to guide LLM input validation.
