## What it does

The skill guides operations with the embedded Neo4j Graph Data Science plugin. It assists in building Cypher procedures and Python workflows using `graphdatascience` 2.x endpoints in snake_case.

Coverage includes graph projections via `gds.graph.project.native`, FastRP embeddings, and memory estimation. The client requires an active GDS plugin. Without it, calls fail with `GdsNotFound`. Aura Graph Analytics remote sessions are out of scope.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add neo4j-contrib/neo4j-skills --skill neo4j-gds-skill -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/neo4j-gds-skill/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/neo4j-gds-skill/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add neo4j-contrib/neo4j-skills --skill neo4j-gds-skill -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/neo4j-gds-skill/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add neo4j-contrib/neo4j-skills --skill neo4j-gds-skill -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/neo4j-gds-skill/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install neo4j-contrib/neo4j-skills neo4j-gds-skill
```

2. **Manually: put the files in place**
- File: `.github/skills/neo4j-gds-skill/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add neo4j-contrib/neo4j-skills --skill neo4j-gds-skill -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/neo4j-contrib/neo4j-skills --path neo4j-gds-skill
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/neo4j-gds-skill/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add neo4j-contrib/neo4j-skills --skill neo4j-gds-skill -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/neo4j-contrib/neo4j-skills/tree/HEAD/neo4j-gds-skill/SKILL.md

## When to use it
- project in-memory graphs using native or Cypher definitions
- run PageRank, Louvain, or FastRP algorithms on graph projections
- chain execution steps using the `mutate` execution mode
- check memory requirements before calculating large graphs

## Example prompts
- Write a Python snippet to project an in-memory graph with gds.graph.project.native
- Run Louvain community detection and stream the resulting community IDs
- Chain FastRP embeddings into a KNN pipeline using mutate mode

description: Neo4j Graph Data Science (GDS) embedded plugin via Python client or Cypher —
  covers graphdatascience client 2.x, GraphDataScience, gds.graph.project.native,
  gds.graph.project.cypher, snake_case endpoints, graph catalog operations,
  stream/stats/mutate/write modes, memory estimation, PageRank, Louvain, WCC, FastRP, KNN,
  Node Similarity, ML pipelines, and cleanup. Use for Aura Pro, self-managed, local, or
  offline Neo4j DBMS with the GDS plugin installed. Does NOT cover Aura Graph Analytics
  GDS Sessions, AuraGraphDataScience, GdsSessions, gds.graph.project.remote, or AuraDB
  Cypher API projection/session management — use neo4j-aura-graph-analytics-skill.
  Does NOT handle Cypher authoring — use neo4j-cypher-skill.
  Does NOT cover driver setup — use neo4j-driver-python-skill or other driver skill.

## When to Use
- Running GDS algorithms against embedded GDS plugin through Python client (`graphdatascience`)
- Running GDS algorithms through `CALL gds.*` Cypher procedures
- Aura Pro, self-managed Neo4j, local Neo4j, or offline DBMS with GDS plugin installed
- Projecting named in-memory graphs, running centrality/community/similarity/path/embedding algorithms
- Chaining algorithms via `mutate` mode; building FastRP → KNN pipelines
- Writing node embeddings for Neo4j vector indexes / structural similarity search
- Memory estimation before large graph operations

## When NOT to Use
- **Aura Graph Analytics Sessions / AGA / `GdsSessions` / `AuraGraphDataScience`** → `neo4j-aura-graph-analytics-skill`
- **AuraDB Cypher API with `{ memory: ... }` or `{ sessionId: ... }`** → `neo4j-aura-graph-analytics-skill`
- **Cypher query authoring** → `neo4j-cypher-skill`
- **Driver/connection setup** → `neo4j-driver-python-skill`
- **GraphRAG retrieval** → `neo4j-graphrag-skill`
- **Creating/querying vector indexes over written embeddings** → `neo4j-vector-index-skill`

| Context | Use |
|---|---|
| Aura Pro with GDS plugin | This skill |
| Self-managed/local/offline Neo4j with GDS plugin | This skill |
| AuraDB serverless analytics session | `neo4j-aura-graph-analytics-skill` |
| Self-managed Neo4j attached to AGA session | `neo4j-aura-graph-analytics-skill` |
| Non-Neo4j data source | `neo4j-aura-graph-analytics-skill` |

---

## Pre-flight

Use only with embedded GDS plugin.

```python
from graphdatascience import GraphDataScience

gds = GraphDataScience("neo4j+s://xxx.databases.neo4j.io", auth=("neo4j", "pw"))   # AuraDS; aura_ds auto-derived
gds = GraphDataScience("bolt://localhost:7687", auth=("neo4j", "password"))
print(gds.server_version())
```

```cypher
RETURN gds.version() AS gds_version
```

GDS plugin unavailable: client raises `GdsNotFound` at construction; Cypher raises `Unknown function 'gds.version'`. AuraDB serverless analytics → `neo4j-aura-graph-analytics-skill`. Self-managed/local → install or enable GDS plugin.

```bash
pip install "graphdatascience>=2.1"          # 2.1 required for GDS 2026.09
pip install "graphdatascience[rust-ext]"     # optional: faster serialization
```
