Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00185 | $0.04539 |
| Opus 5 | $0.00093 | $0.02269 |
| Sonnet 5 | $0.00037 | $0.00908 |
| Haiku 4.5 | $0.00018 | $0.00454 |
Grade A, and why
neo4j-spark-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 12d 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.
How it starts

Neo4j Connector for Apache Spark
When to Use
- Reading Neo4j nodes/relationships into Spark DataFrames
- Writing Spark DataFrames to Neo4j as nodes or relationships
- Databricks notebooks connecting to Neo4j
- Delta Lake → Neo4j ingestion pipelines
- Partitioned parallel reads from large Neo4j graphs
When NOT to Use
- Python bolt driver / execute_query →
neo4j-driver-python-skill - Cypher query writing →
neo4j-cypher-skill - GDS graph algorithms →
neo4j-gds-skill - Spring Boot + Neo4j →

Version Matrix
| Connector | Spark | Scala | Java | Databricks Runtime | Neo4j | Maven coordinate |
|---|---|---|---|---|---|---|
| 6.0.x | 4.0, 4.1 | 2.13 | 17+ | 17.3 LTS | 5.x, 2025.x, 2026.x | org.neo4j.connectors:spark:6.0.0-s_2.13 |
| 5.5.x / 5.4.x | 3.4, 3.5 | 2.12, 2.13 | 8+ | 14.3–16.4 LTS | 4.4, 5.x, 2025.x, 2026.x | org.neo4j:neo4j-connector-apache-spark_2.13:5.5.0_for_spark_3 |
Group ID changed in 6.0 — org.neo4j:neo4j-connector-apache-spark_<scala> is now a relocation POM pointing at org.neo4j.connectors:spark. On Spark 3.x stay on 5.5.x.
6.0 breaking changes
| Change | Migration |
|---|---|
| Spark baseline 3.5 → 4.0/4.1; Scala 2.12 and Java 8–11 dropped | Upgrade to 5.5.0 first, then Spark 4.x + Scala 2.13 + Java 17 |
Maven coordinate org.neo4j.connectors:spark:<version>-s_2.13 |
Replace old _for_spark_3 coordinate |
schema.optimization.type removed |
schema.optimization.node.keys, schema.optimization.relationship.keys, schema.optimization |
$stream.offset in partitioned reads removed |
Use partitions + query.count |
;-separated multi-statement script removed |
script.1, script.2, … script.N — executed in numbered order |
relationship.save.strategy default native → keys |
Set .option("relationship.save.strategy", "native") explicitly to keep old behaviour |
query option rewritten for Data Source V2 predicate push-down |
No action; verify plans on upgrade |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

neo4j-spark-skill is a skill published in the GitHub repository neo4j-contrib/neo4j-skills (109 stars, last pushed 5d ago), licensed MIT. It adds 185 tokens to every session and 4,539 once invoked, about $0.0009 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 2026-08-30.
