Diagnoses and fixes slow Neo4j Cypher queries by reading execution plans, identifying.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## When to Use
- Query takes unexpectedly long; need root-cause analysis
- EXPLAIN/PROFILE output in hand — needs interpretation
- Identifying which index is missing or unused
- Deciding between slotted / pipelined / parallel runtimes
- Monitoring live queries: SHOW QUERIES, SHOW TRANSACTIONS
- Cardinality estimates wrong (plan replanning needed)
## When NOT to Use
- **Writing Cypher from scratch** → `neo4j-cypher-skill`
- **GDS algorithm performance** → `neo4j-gds-skill`
- **Schema design / data modelling** → `neo4j-modeling-skill`
---
## EXPLAIN vs PROFILE
| | EXPLAIN | PROFILE |
|---|---|---|
| Executes query? | No | Yes |
| Returns data? | No | Yes |
| Shows `rows` (actual) | No | Yes |
| Shows `dbHits` (actual) | No | Yes |
| Shows `estimatedRows` | Yes | Yes |
| Cost | Zero | Full query cost |
Run `PROFILE` **twice** — first run warms page cache; second gives representative metrics.
```cypher
EXPLAIN MATCH (p:Person {email: $email}) RETURN p.name
PROFILE MATCH (p:Person {email: $email}) RETURN p.name
```
Query API alternative (no driver):
```bash
curl -X POST https://<host>/db/<db>/query/v2 \
-u <user>:<pass> -H "Content-Type: application/json" \

How to install
mdr add neo4j-contrib/neo4j-skills/neo4j-query-tuning-skill@sha256:e63397ed90c91e45The line at the top of this page pins the label v1.0.9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
