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.

SkillSpector: 3 findings, up to medium
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 →
- medium Data Exfiltration · line 393 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

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 | $0.00177 | $0.05420 |
| Opus 5 | $0.00088 | $0.02710 |
| Sonnet 5 | $0.00035 | $0.01084 |
| Haiku 4.5 | $0.00018 | $0.00542 |
Grade A, and why
neo4j-import-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.

Neo4j Import Skill
When to Use
- Importing CSV, JSON, or Parquet files into Neo4j
- Batch-upserting nodes and relationships (UNWIND + CALL IN TRANSACTIONS)
- Migrating relational data (SQL → graph)
- Bulk-loading large datasets offline (neo4j-admin import)
- Choosing between online (Cypher) and offline (admin) import methods
- Verifying import completeness (counts, constraints, index states)
When NOT to Use
- Unstructured docs, PDFs, vector chunks →
neo4j-document-import-skill - Live application writes (MERGE/CREATE in app code) →
neo4j-cypher-skill - neo4j-admin backup/restore/config →
neo4j-cli-tools-skill - GDS algorithm projection from existing graph →

Method Decision Table
| Dataset size | DB state | Source | Method |
|---|---|---|---|
| Any size | Online | CSV (Aura or local) | LOAD CSV + CALL IN TRANSACTIONS |
| < 1M rows | Online | List/API response | UNWIND + CALL IN TRANSACTIONS |
| > 10M rows | Offline (local/self-managed) | CSV / Parquet | neo4j-admin database import full |
| Any size | Online | APOC available | apoc.periodic.iterate + apoc.load.csv |
| Any size | Online | JSON/API | apoc.load.json or driver batching |
| Incremental delta | Offline (Enterprise) | CSV | neo4j-admin database import incremental |
Aura: only https:// URLs — no file:///. Use neo4j-admin import only on self-managed.
Pre-Import Checklist
Run in this exact order — skipping causes hard-to-debug duplicates or missed index usage:
Constraints BEFORE import. Additional indexes AFTER import.
- Constraints create implicit RANGE indexes used by MERGE during load + enforce uniqueness
- Additional non-unique indexes (TEXT, RANGE on non-key props, FULLTEXT) created after load — Neo4j populates them async from the committed data; poll
populationPercentuntil 100% - Creating extra indexes before import slows every write during load with no benefit
- Create uniqueness constraints (enables index used by MERGE):
CREATE CONSTRAINT IF NOT EXISTS FOR (n:Person) REQUIRE n.id IS UNIQUE; CREATE CONSTRAINT IF NOT EXISTS FOR (n:Movie) REQUIRE n.movieId IS UNIQUE;Neo4j 2026.06+ (Enterprise/Aura, GA):
ALTER CURRENT GRAPH TYPE SET { … }replaces all individual constraint statements with a single declarative block. Seeneo4j-cypher-skill/references/graph-type.md. Use individualCREATE CONSTRAINTon Community Edition or pre-2026.02.
What ships with it
4 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-import-skill is a skill published in the GitHub repository neo4j-contrib/neo4j-skills (109 stars, last pushed 5d ago), licensed MIT. It adds 177 tokens to every session and 5,420 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.
