Four tools with complete schemas and basic descriptions, but significant gaps in parameter documentation and error handling guidance. All tools are READ_ONLY, which is appropriate, but descriptions lack actionable context for LLM selection. Parameter descriptions are minimal (e.g., 'Name pattern to search for' without format constraints). No output schemas documented. Error handling provides no recovery guidance. Naming is clear and verb-based (search_, get_, list_), following baseline conventions.

• Add output schema documentation to all tools. Example for search_nodes: 'Returns {success: bool, count: int, nodes: [{id: string, node_type: string}]}'. This enables LLMs to chain calls and extract node_id for get_node_context.
• Replace example values in descriptions with formal constraints. Change 'supports wildcards like 'main', 'Parser'' to 'Supports * and ? wildcards; case-sensitive'. Remove example values to prevent literal reuse.
• Enhance error responses with actionable recovery guidance. Instead of generic 500 errors, return structured errors: {error: 'node_not_found', message: 'Node src/main.rs:main not found', suggestion: 'Try search_nodes(pattern="main") to find available nodes'}.
• Add pagination parameters (limit, offset) to search_nodes and get_dependency_graph. Document result caps (e.g., 'Returns max 50 results; use offset for pagination'). Prevents context window exhaustion.
• Clarify tool selection in descriptions. For get_node_context vs get_dependency_graph: 'get_node_context: Returns source code + immediate dependencies (useful for understanding implementation). get_dependency_graph: Returns full dependency tree (useful for impact analysis).'
