Mixed quality across 5 tools. All tools have descriptions (10-100 chars, mostly adequate) and input schemas with types. However, schemas lack depth: parameter descriptions are minimal or absent in several tools (graphify_ping has empty input {}; graphify_store/relate/retrieve descriptions are terse). No output schemas documented. Error handling guidance is absent. Tool naming is verb-noun compliant but generic (graphify_* prefix adds little semantic value). Composition is reasonable, tools chain well (retrieve → store → relate), but lack idempotency guarantees and recovery guidance. No tool annotations (readOnlyHint/destructiveHint) despite clear risk levels. STDIO transport caps protocol readiness at 50.

• Add output schemas to all tools. E.g., search_vault should document: {results: [{id, title, content, score}], total_count}. graphify_retrieve should return {nodes: [{id, type, title, score}], edges: [{from_id, rel_type, to_id}]}.
• Add tool annotations: mark graphify_store and graphify_relate with destructiveHint=true and idempotentHint=true (since they use MERGE). Mark read-only tools with readOnlyHint=true.
• Expand parameter descriptions with format/range constraints. E.g., graphify_store id: 'Unique identifier (lowercase alphanumeric + hyphens, max 64 chars, e.g. dec-008-langgraph)'. graphify_retrieve min_score: 'Minimum relevance score (0.0 - 1.0, default 0.5)'.
• Add error handling guidance to tool descriptions. E.g., graphify_ping: 'Returns error if Neo4j or Qdrant unreachable. Check NEO4J_URI, QDRANT_URL env vars and service health.'
• Document idempotency guarantees. E.g., graphify_store: 'Idempotent, calling twice with same id/content produces one node (MERGE on id). Safe to retry.'
