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.

- NVIDIA SkillSpector warn
SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 48 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00186 | $0.04438 |
| Opus 5.5 | $0.00074 | $0.01775 |
| Sonnet 5.5 | $0.00037 | $0.00888 |
| Haiku 4.5 | $0.00019 | $0.00444 |
Grade A, and why
neo4j-driver-python-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 6d 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
The opening of the file, as written. The whole thing — 435 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
- Writing Python code that connects to Neo4j
- Setting up driver, sessions, transactions, or async patterns
- Debugging result handling, serialization, or UNWIND batching
- Reviewing Neo4j driver usage in Python code
When NOT to Use
- Writing/optimizing Cypher →
neo4j-cypher-skill - Driver version upgrades →
neo4j-migration-skill - GraphRAG pipelines (

Installation
pip install neo4j # package name is `neo4j`, NOT `neo4j-driver` (deprecated since v6)
pip install neo4j-rust-ext # optional: 3–10× faster serialization, same API
Python >=3.10 required for v6.x. Python 3.14 supported [6.1+]. Pandas 3 and PyArrow 23/24 supported [6.2+]. PyArrow 25 and Bolt 6.1 uuid.UUID values supported [6.3+]; driver-created SSL contexts honour SSLKEYLOGFILE [6.3+]. Python 3.15 supported [6.4+]. Pin neo4j>=6.4.1 — 6.4.0 can spin forever on pool acquisition and double-encodes bearer tokens over HTTP Query API.
Neo4j 2026.08+ UUID properties require neo4j>=6.3 to round-trip as uuid.UUID. Storing UUID needs block store format (Enterprise); Community (aligned format) fails: storing properties of type UUID is not supported in aligned store format — store str(uuid).
Environment Variables
Load connection config from environment — never hardcode credentials.
import os
from dotenv import load_dotenv # pip install python-dotenv
load_dotenv(".env") # reads NEO4J_URI / NEO4J_USERNAME / NEO4J_PASSWORD / NEO4J_DATABASE
URI = os.getenv("NEO4J_URI", "neo4j://localhost:7687")
USER = os.getenv("NEO4J_USERNAME", "neo4j")
PASSWORD = os.getenv("NEO4J_PASSWORD", "")
DATABASE = os.getenv("NEO4J_DATABASE", "neo4j")
.env file format:
NEO4J_URI=neo4j+s://xxx.databases.neo4j.io
NEO4J_USERNAME=neo4j
NEO4J_PASSWORD=secret
NEO4J_DATABASE=neo4j
Add .env to .gitignore. Without python-dotenv, use export in shell or os.getenv directly.
What ships with it
5 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-driver-python-skill is a skill published in the GitHub repository neo4j-contrib/neo4j-skills (116 stars, last pushed 4d ago), licensed MIT. It adds 186 tokens to every session and 4,438 once invoked, about $0.0007 per session on Opus 5.5. 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.
