neo4j-graphrag-skill

neo4j-graphrag-skill is a skill for Claude Code from neo4j-contrib/neo4j-skills. It costs 228 tokens per session (5,177 once invoked), scanned A, original, MIT.

A guide for building GraphRAG retrieval systems with Neo4j. GraphRAG combines a language model with searches through a knowledge graph and can use vector, full-text, or Cypher-based retrieval.

In plain words
What is it for?
Selecting Neo4j retrievers, writing retrieval queries, connecting retrievers to language models, routing between retrievers, and debugging retrieval quality.
Why use it?
It helps choose and connect the right retriever when ordinary document search is not enough and relationships between data matter.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

neo4j-graphrag-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Neo4j GraphRAG Skill

When to Use

  • Building GraphRAG retrieval pipelines with neo4j-graphrag Python package
  • Choosing between VectorRetriever, HybridRetriever, VectorCypherRetriever, HybridCypherRetriever
  • Writing retrieval_query Cypher fragments for graph-augmented context
  • Wiring retriever + LLM into a GraphRAG pipeline
  • Using LLM-routed multi-retriever with ToolsRetriever
  • Debugging low retrieval quality
  • Integrating Neo4j with LangChain, LlamaIndex, or Haystack

When NOT to Use

  • KG construction from documentsneo4j-document-import-skill
  • Plain vector/semantic search without graph traversalneo4j-vector-index-skill
  • Hybrid search that combines vector with fulltext or other ranked sourcesneo4j-vector-index-skill
  • GDS algorithms (PageRank, Louvain, node embeddings)neo4j-gds-skill
  • Agent long-term memoryneo4j-agent-memory-skill
  • Writing raw Cypher queriesneo4j-cypher-skill

Retriever Selection

Has fulltext index?
  YES → Hybrid variants (HybridRetriever / HybridCypherRetriever)
  NO  → Vector variants (VectorRetriever / VectorCypherRetriever)

Need graph traversal after vector lookup?
  YES → Cypher variants (VectorCypherRetriever / HybridCypherRetriever)
  NO  → plain variants

Natural-language-to-Cypher?        → Text2CypherRetriever (no embedder needed)
LLM should route between retrievers? → ToolsRetriever
Vectors stored in external DB?      → WeaviateNeo4jRetriever / PineconeNeo4jRetriever / QdrantNeo4jRetriever
Retriever Vector Fulltext Graph Best For
VectorRetriever Baseline semantic search

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
