data-graph-database

data-graph-database is a skill for Claude Code, Codex from j4flmao/agent-skills. It costs 130 tokens per session (5,386 once invoked), scanned A, original, MIT.

A guide to graph databases, which store entities as nodes and their connections as relationships. It covers systems such as Neo4j and Neptune and query languages such as Cypher and Gremlin.

In plain words
What is it for?
Use it to design knowledge graphs, recommendation systems, fraud investigations, social networks, and graph traversals.
Why use it?
It helps model and query data where the connections between things matter as much as the things themselves.

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

data-graph-database 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 9d 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.

Data Graph Database

Purpose

Design graph data models for connected domains (social networks, recommendation engines, knowledge graphs, fraud detection) with optimal traversal patterns, platform selection, and scaling strategy.

Agent Protocol

Trigger

Exact user phrases: "Neo4j", "Amazon Neptune", "JanusGraph", "graph database", "graph model", "Cypher", "Gremlin", "RDF", "SPARQL", "graph traversal", "property graph", "knowledge graph", "graph schema", "node label", "relationship", "graph query".

Input Context

Before activating, verify:

  • Domain data (nodes, relationships, properties, cardinality)
  • Query patterns (depth of traversal, path enumeration, aggregations)
  • Transaction volume (reads/sec, writes/sec, complexity)
  • Consistency requirements (ACID vs CQRS)
  • Existing graph platform or greenfield
  • Integration points (existing databases, streaming, ML pipelines)
  • Expected graph size (millions, billions of nodes/edges)

Output Artifact

Graph data model with node labels, relationship types, traversal patterns, and platform-specific deployment config.

Response Format

// Neo4j schema + constraints + traversal queries
// Gremlin traversals for Neptune/JanusGraph
# JanusGraph storage backend config
# Neptune cluster config

No preamble. No postamble. No explanations. No filler/hedging/transitions. Compress output — why use many token when few do trick.

Completion Criteria

  • Graph data model designed (property graph or RDF)
  • Node labels and relationship types defined with constraints
  • Indexes created for high-traffic property lookups
  • Traversal patterns optimized for depth and cardinality
  • Platform selected (Neo4j, Neptune, JanusGraph) with rationale
  • Scaling strategy defined (sharding, replication, caching)
  • Query performance verified with PROFILE/explain

Max Response Length

300 lines of schema and queries.

Workflow

Step 1: Graph Data Modeling

Property graph: nodes (entities) with labels, relationships (edges) with types, properties on both. RDF: subject-predicate-object triples with URIs. Design around traversal patterns: ask "what queries will traverse from this node through which relationships?" Favor nodes for entities, relationships for connections, properties for attributes.

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.

data-graph-database is a skill published in the GitHub repository j4flmao/agent-skills (23 stars, last pushed 6d ago), licensed MIT. It adds 130 tokens to every session and 5,386 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
