The server defines 5 tools covering jOOQ documentation and reference material. Tools use clear action verbs (search, get) and have reasonable descriptions (120-180 chars each). However, schemas are problematic: only 2 of 5 tools have visible input parameters with type information; 3 tools have either empty schemas or no type annotations visible in the source. Parameter descriptions are present but minimal. No output schemas are documented. Error handling exists at the HTTP level (GlobalExceptionHandler) but tools themselves provide no recovery guidance. Security is adequate (read-only operations, no secrets exposed). Composition is good, tools are single-responsibility and chaining-capable via consistent naming.

• Add explicit output schemas to all 5 tools. Document response structure (e.g., 'Returns {sections: [{title: string, content: string, relevance: number}], total: number}'). This enables LLMs to understand what fields are available and plan multi-step workflows.
• Convert 'database' parameter in getDatabaseSupport to an enum with valid values: MySQL, PostgreSQL, Oracle, SQL Server, H2, MariaDB, etc. This prevents hallucinated database names and makes the tool self-documenting.
• Expand parameter descriptions to 50-100 chars each. For 'topic' in getSqlExamples, provide guidance: 'SQL operation topic: SELECT, INSERT, UPDATE, DELETE, JOIN, subqueries, CTEs, window functions, etc.'
• Add pagination parameters (limit, offset or cursor) to searchDocumentation and getSqlExamples. Document result limits in tool descriptions (e.g., 'Returns up to 20 matching sections; use offset to paginate').
• Add error recovery hints to tool descriptions. For getDatabaseSupport: 'If database not recognized, call searchDocumentation with "database support" first.' For searchDocumentation: 'If no results, try broader search terms or call getQueryDslReference() for reference material.'
• Document known limitations. If getCodeGenerationGuide always returns the same content (a static guide), state that in the description so LLMs know not to call it repeatedly.
