Three tools with complete schemas and descriptions, but descriptions are generic and lack LLM-optimized guidance. All tools are read-only with proper enums for constrained inputs. Missing output schema documentation, error handling guidance, and parameter relationship documentation. Tool names follow verb_noun pattern correctly. No security or composition issues detected.

• Document output schemas for all three tools. Example: 'Returns {results: [{title: string, content: string, source: string}], total_matches: number}'. This enables LLMs to extract and chain results.
• Expand tool descriptions to 100-150 chars with explicit guidance: 'search_live_guide: Search Go style guides for specific patterns (naming, error handling, concurrency). Use when you need to find guidance on a specific coding practice. Returns matching sections with source.'
• Add format and constraint guidance to 'query' parameter: 'Search query (1-200 chars, case-insensitive). Examples: "error handling", "goroutine safety", "interface design". Partial matches supported.'
• Add topic descriptions to enum values in get_guide_topic and get_review_guidelines. Example: 'topic enum: naming (variable/function naming conventions), errors (error handling patterns), concurrency (goroutine/channel safety), testing (test structure), interfaces (interface design), formatting (code style), comments (documentation), imports (import organization), context (context.Context usage)'.
• Implement error handling guidance in descriptions: 'Returns error if query is empty or topic is invalid. If no matches found, returns empty results with suggestion to broaden query or try related topics.'
