# Send Neo4j to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### MERGE Trap

MERGE matches the FULL pattern—MERGE (a)-[:KNOWS]->(b) creates duplicates if relationship missing
Safe upsert: merge nodes separately, then merge relationship
Use ON CREATE SET and ON MATCH SET for conditional properties—without these, nothing updates on match
For simple node upsert: MERGE (n:User {id: $id}) with unique constraint on id

### Indexes

No index on property = full label scan—always index properties used in WHERE
Unique constraint auto-creates index—prefer constraint over plain index when applicable
Check plan with EXPLAIN before production—look for "NodeByLabelScan" without filter pushdown
Text search needs full-text index: CREATE FULLTEXT INDEX FOR (n:Post) ON EACH [n.title, n.body]

### Variable-Length Paths

Unbounded [*] explodes on connected graphs—always set upper bound [*1..5]
[*0..] includes start node—usually unintended, start from [*1..]
shortestPath() returns one path only—use allShortestPaths() for all equally short paths
Filter inside path is expensive: [r:KNOWS* WHERE r.active] scans then filters—consider data model change

### Cartesian Product

Two disconnected patterns multiply: MATCH (a:User), (b:Product) returns rows × rows
Connect patterns or split with WITH—unintended cartesian kills performance
Same variable in two patterns = implicit join, no cartesian
PROFILE query shows "CartesianProduct" operator when it happens

### WITH Scope Reset

Only variables in WITH carry forward—MATCH (a)--(b) WITH a loses b
Aggregation forces WITH: MATCH (u:User) WITH u.country AS c, count(*) AS n
Common mistake: filtering after aggregation requires second WITH
Pagination: WITH n ORDER BY n.created SKIP 10 LIMIT 10

### NULL Propagation

OPTIONAL MATCH returns NULL for missing patterns—NULLs propagate through expressions
WHERE after OPTIONAL MATCH filters out NULLs—use COALESCE() to preserve rows
count(NULL) returns 0—useful: OPTIONAL MATCH (u)-[:REVIEWED]->(p) RETURN count(p)
Property access on NULL throws no error, returns NULL—silent data loss

### Direction

Query direction ignored with no arrow: (a)-[:KNOWS]-(b) matches both ways
Creation requires direction—must pick one, can't create undirected
Wrong direction = empty results—if relationship is (a)-[:OWNS]->(b), query (b)-[:OWNS]->(a) finds nothing

### Batch Operations

Large creates in single transaction exhaust heap—use CALL {} IN TRANSACTIONS OF 1000 ROWS
UNWIND $list AS item CREATE (n:Node {id: item.id}) for batch inserts
apoc.periodic.iterate() for complex batch logic with progress
Delete in batches: MATCH (n:Old) WITH n LIMIT 10000 DETACH DELETE n in loop

### Parameter Injection

Always use parameters $param not string concatenation—prevents Cypher injection
Parameters also enable query plan caching—literal values recompile each time
Pass as map: {param: value} in driver, :param {param: value} in browser
List parameter for IN: WHERE n.id IN $ids
