## What it does

The skill guides graph architecture decisions, helping you pick between Neptune Database for transactional traversals and Neptune Analytics for batch algorithms. It assists with openCypher, Gremlin, and SPARQL queries, Neo4j migrations, and GraphRAG pipelines. When creating or updating resources, the agent stops and asks for explicit confirmation before calling AWS commands.

Safety rules are strictly enforced. The skill rejects destructive actions like deleting clusters, running `reset-graph`, or initiating cluster failover, routing those changes to the AWS Console. Every created resource receives mandatory `created_by=neptune-skill` and `generation_model` tags. Storage encryption is applied by default because Neptune Database does not encrypt at rest automatically through the CLI.

Deploying Neptune Database requires a subnet group spanning at least two availability zones inside a VPC. Public endpoints cannot use open `0.0.0.0/0` inbound rules and require IAM authentication. Analytics memory resizing or version changes trigger warnings about potential brief query disruptions before proceeding.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-neptune -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-neptune -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-neptune -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws amazon-neptune
```

2. **Manually: put the files in place**
- File: `.github/skills/amazon-neptune/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-neptune -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/specialized-skills/database-skills/amazon-neptune
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill amazon-neptune -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/aws/agent-toolkit-for-aws/tree/HEAD/skills/specialized-skills/database-skills/amazon-neptune/SKILL.md

## When to use it
- choose between Neptune Database and Neptune Analytics engines
- tune graph queries in openCypher, Gremlin, and SPARQL
- run PageRank and community detection in Neptune Analytics
- deploy an encrypted Neptune cluster inside a VPC with IAM auth

## Example prompts
- Help me pick between Neptune Database and Neptune Analytics for a fraud ring detection system.
- Create a Neptune Database cluster in our VPC with storage encryption enabled.
- Write an openCypher query to trace user identity resolution across sessions.

description: Provides authoritative guidance on Amazon Neptune Database and Neptune Analytics for graph, knowledge-graph, and relationship-heavy workloads — fraud detection / fraud rings, agentic memory / chatbot context across sessions, recommendations, identity resolution, Gremlin / openCypher / SPARQL queries, supernode / slow traversal, Neo4j to Neptune migration / APOC compatibility, Neptune Database vs Analytics engine selection, PageRank / community detection, GraphRAG, and connectivity from Lambda / EC2 / applications. Creates and modifies Neptune Database clusters/instances and Neptune Analytics graphs on explicit user confirmation; blocks destructive operations (delete, reset-graph, failover, major upgrade) and redirects to change-control.

# Amazon Neptune

## Safety guidance

This skill covers creating and modifying Neptune resources when the user requests it. The agent MUST confirm the action with the user before executing. Do NOT execute any create or modify operation without explicit user confirmation (e.g., "yes", "proceed", "confirmed", "go ahead"). If the user has not confirmed, present the planned action and ask for approval.

### Execute these operations (after user confirmation)

**Neptune Database:**

- Create a cluster: `create-db-cluster` (requires a DB subnet group with subnets in ≥2 AZs — Neptune is deployed inside a VPC; optional public endpoints are supported with IAM auth — check the Neptune userguide "public endpoints" page for the minimum engine version). When enabling a public endpoint, ALSO scope the cluster's security-group inbound rule on port 8182 to known CIDR ranges or trusted source security groups — do NOT use `0.0.0.0/0`.
- Create an instance (add writer or reader to a cluster): `create-db-instance`
- Change backup retention: `modify-db-cluster --backup-retention-period`
- Enable/disable deletion protection: `modify-db-cluster --deletion-protection`
- Change CloudWatch log exports: `modify-db-cluster --enable-cloudwatch-logs-exports`
- Tag resources: `add-tags-to-resource`, `remove-tags-from-resource`

**Neptune Analytics:**

- Create a graph: `create-graph`
- Create a graph from S3 data: `create-graph-using-import-task`
- Create a graph snapshot (point-in-time backup): `create-graph-snapshot`
- Tag resources: `tag-resource`, `untag-resource`
```
