Single tool (mykg_search_nodes) with acceptable naming and reasonable description, but lacks critical parameter descriptions and comprehensive output schema documentation. Tool name follows verb_noun pattern ('search_nodes') which is good, but the input schema is incomplete: 'type' and 'limit' parameters have descriptions but lack explicit type declarations in the visible schema structure. The tool description (153 chars) is adequate but does not fully explain what fields are returned or how results are ranked beyond the brief ranking statement. No error handling guidance is documented. The server relies on STDIO transport which is a hard architectural limitation.

• Document the complete output schema with explicit field names, types, and descriptions. Example: {"results": [{"node_id": string, "name": string, "type": string, "confidence_score": float, "rank_method": string}], "total_count": integer}
• Add constraints to numeric parameters in the schema: limit should specify minimum=1, maximum=100 (or appropriate ceiling), with default=20
• Expand tool description to include: 'Returns ranked search results for nodes in the knowledge graph. Prefer exact name matches, then prefix, then substring, then alias, then attribute values. Use this to discover node IDs before calling other tools like mykg_get_node.'
• Add parameter descriptions: 'type: Filter results to nodes of this type only (optional). Omit to search across all types.' and 'limit: Maximum number of results to return (1-100, default 20).'
• Document error cases with recovery guidance: 'No matches found. Try simplifying the query or use a shorter substring.' and 'Limit exceeds maximum (100). Use pagination with smaller limits.'
• Consider adding a 'match_method' field to results so LLMs understand why a particular node was ranked (useful for explaining search quality to users)

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
