Memory Fabric - Graph Orchestration
Knowledge graph orchestration via mcp__memory__* for entity extraction, query parsing, deduplication, and cross-reference boosting.
Overview
Comprehensive memory retrieval from the knowledge graph
Cross-referencing entities within graph storage
Ensuring no relevant memories are missed
Building unified context from graph queries

Unified Search Workflow
Step 1: Parse Query Extract search intent and entity hints from natural language:
Input: "What pagination approach did database-engineer recommend?"
Parsed:
- query: "pagination approach recommend"
- entity_hints: ["database-engineer", "pagination"]
- intent: "decision" or "pattern"
Step 2: Execute Graph Query Query Graph (entity search):
mcp__memory__search_nodes ({
query : "pagination database-engineer"
})
Step 3: Normalize Results Transform results to common format:
{
"id" : "graph:original_id" ,
"text" : "content text" ,
"source" : "graph" ,
"timestamp" : "ISO8601" ,
"relevance" : 0.0 -1.0 ,
"entities" : [ "entity1" , "entity2" ] ,
"metadata" : { }
}
Step 4: Deduplicate (>85% Similarity) When two results have >85% text similarity:
Keep the one with higher relevance score
Merge metadata
Mark as "cross-validated" for authority boost
Step 5: Cross-Reference Boost If a result mentions an entity that exists elsewhere in the graph:
Boost relevance score by 1.2x
Add graph relationships to result metadata
Step 6: Final Ranking Score = recency_factor × relevance × source_authority
Factor Weight Description recency 0.3 Newer memories rank higher relevance 0.5 Semantic match quality source_authority 0.2 Graph entities boost, cross-validated boost
Result Format {
"query" : "original query" ,
"total_results" : 4 ,
"sources" : {
"graph" : 4
} ,
"results" : [
{
"id" : "graph:cursor-pagination" ,
"text" : "Use cursor-based pagination for scalability" ,
"score" : 0.92 ,
"source" : "graph" ,
"timestamp" : "2026-01-15T10:00:00Z" ,
"entities" : [ "cursor-pagination" , "database-engineer" ] ,
"graph_relations" : [
{ "from" : "database-engineer" , "relation" : "recommends" , "to" : "cursor-pagination" }
]
}
]
}
Entity Extraction Memory Fabric extracts entities from natural language for graph storage:
Input: "database-engineer uses pgvector for RAG applications"
Extracted:
- Entities:
- { name: "database-engineer", type: "agent" }
- { name: "pgvector", type: "technology" }
- { name: "RAG", type: "pattern" }
- Relations:
- { from: "database-engineer", relation: "uses", to: "pgvector" }
- { from: "pgvector", relation: "used_for", to: "RAG" }
Load Read("${CLAUDE_SKILL_DIR}/references/entity-extraction.md") for detailed extraction patterns.
Graph Relationship Traversal Memory Fabric supports multi-hop graph traversal for complex relationship queries.
Example: Multi-Hop Query Query: "What did database-engineer recommend about pagination?"
1. Search for "database-engineer pagination"
→ Find entity: "database-engineer recommends cursor-pagination"
2. Traverse related entities (depth 2)
→ Traverse: database-engineer → recommends → cursor-pagination
→ Find: "cursor-pagination uses offset-based approach"
3. Return results with relationship context
Integration with Graph Memory Memory Fabric uses the knowledge graph for entity relationships:
Graph search via mcp__memory__search_nodes finds matching entitiesGraph traversal expands context via entity relationshipsCross-reference boosts relevance when entities match
Integration Points
With memory Skill When memory search runs, it can optionally use Memory Fabric for unified results.
With Hooks
prompt/memory-fabric-context.sh - Inject unified context at session startstop/memory-fabric-sync.sh - Sync entities to graph at session end
Configuration
MEMORY_FABRIC_DEDUP_THRESHOLD=0.85
MEMORY_FABRIC_BOOST_FACTOR=1.2
MEMORY_FABRIC_MAX_RESULTS=20
MCP Requirements Required: Knowledge graph MCP server:
{
"mcpServers" : {
"memory" : {
"command" : "npx" ,
"args" : [ "-y" , "@anthropic/memory-mcp-server" ]
}
}
}
Error Handling Scenario Behavior graph unavailable Error - graph is required Query empty Return recent memories from graph
