## What it does

This skill guides Amazon S3 configuration with AWS CLI. Its quick-start example creates a bucket, enables versioning, blocks public access, and applies AES256 server-side encryption. The guidance also covers bucket policies, logging, MFA Delete, and replication across regions.

The `references/` directory contains guides for bucket setup, lifecycle rules, Terraform configuration, and presigned URLs. These can inform setups for backups, application assets, and analytics. Review access policies carefully: an overly permissive policy or a public bucket puts stored data at risk.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill aws-s3-management -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/aws-s3-management/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/aws-s3-management/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill aws-s3-management -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/aws-s3-management/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill aws-s3-management -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/aws-s3-management/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts aws-s3-management
```

2. **Manually: put the files in place**
- File: `.github/skills/aws-s3-management/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill aws-s3-management -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/aws-s3-management
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/aws-s3-management/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill aws-s3-management -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/aj-geddes/useful-ai-prompts/tree/HEAD/skills/aws-s3-management/SKILL.md

## When to use it
- create an S3 bucket with AWS CLI
- turn on object versioning
- prevent public access to a bucket
- configure encryption and lifecycle rules
- set up access with presigned URLs

## Example prompts
- Configure an S3 bucket for backups with versioning, encryption, and public access blocked.
- Plan the bucket settings for hosting a static site on S3.
- Show me how to set S3 lifecycle rules and grant access with presigned URLs.

## Overview

Amazon S3 provides secure, durable, and highly scalable object storage. Manage buckets with encryption, versioning, access controls, lifecycle policies, and cross-region replication for reliable data storage and retrieval.

## When to Use

- Static website hosting
- Data backup and archival
- Media library and CDN origin
- Data lake and analytics
- Log storage and analysis
- Application asset storage
- Disaster recovery
- Data sharing and collaboration

## Quick Start

Minimal working example:

```bash
# Create bucket
aws s3api create-bucket \
  --bucket my-app-bucket-$(date +%s) \
  --region us-east-1

# Enable versioning
aws s3api put-bucket-versioning \
  --bucket my-app-bucket \
  --versioning-configuration Status=Enabled

# Block public access
aws s3api put-public-access-block \
  --bucket my-app-bucket \
  --public-access-block-configuration \
    BlockPublicAcls=true,IgnorePublicAcls=true,\
    BlockPublicPolicy=true,RestrictPublicBuckets=true

# Enable encryption
aws s3api put-bucket-encryption \
  --bucket my-app-bucket \
  --server-side-encryption-configuration '{
    "Rules": [{
      "ApplyServerSideEncryptionByDefault": {
        "SSEAlgorithm": "AES256"
      }
// ... (see reference guides for full implementation)
```

| [S3 Access with Presigned URLs](references/s3-access-with-presigned-urls.md) | S3 Access with Presigned URLs |

## Best Practices

### ✅ DO

- Enable versioning for important data
- Use server-side encryption
- Block public access by default
- Implement lifecycle policies
- Enable logging and monitoring
- Use bucket policies for access control
- Enable MFA delete for critical buckets
- Use IAM roles instead of access keys
- Implement cross-region replication

### ❌ DON'T

- Make buckets publicly accessible
- Store sensitive credentials
- Ignore CloudTrail logging
- Use overly permissive policies
- Forget to set lifecycle rules
- Ignore encryption requirements
