## What it does

This skill guides your coding agent through creating a multi-region AWS CloudTrail configuration across all regions. It establishes centralized API activity logging into an S3 bucket, streams logs to CloudWatch Logs, and sets up CloudWatch Logs Insights queries for compliance auditing.

The skill outlines steps from `references/cloudtrail-multi-region-setup.md` and provides targeted troubleshooting. It instructs you to check caller credentials with `aws sts get-caller-identity` and explicitly warns against attaching `*FullAccess` managed policies. The CloudWatch log group must reside in the exact same region as the trail itself.

Log delivery requires patience. Initial events need 5 to 15 minutes to show up after running `start-logging`, while opt-in AWS regions can take up to 24 hours to surface events.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill setting-up-cloudtrail-multi-region -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill setting-up-cloudtrail-multi-region -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/setting-up-cloudtrail-multi-region/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill setting-up-cloudtrail-multi-region -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/setting-up-cloudtrail-multi-region/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws setting-up-cloudtrail-multi-region
```

2. **Manually: put the files in place**
- File: `.github/skills/setting-up-cloudtrail-multi-region/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill setting-up-cloudtrail-multi-region -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/specialized-skills/operations-skills/setting-up-cloudtrail-multi-region
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/setting-up-cloudtrail-multi-region/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill setting-up-cloudtrail-multi-region -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/operations-skills/setting-up-cloudtrail-multi-region/SKILL.md

## When to use it
- enable centralized AWS API activity logging across all regions
- route CloudTrail events to Amazon S3 and CloudWatch Logs
- configure CloudWatch Logs Insights queries for security audits
- troubleshoot trail logging failures and permission denied errors

## Example prompts
- Set up a multi-region CloudTrail trail with S3 storage and CloudWatch Logs
- Check why events are missing from CloudWatch after creating my trail
- Configure CloudWatch Logs Insights queries for audit analysis

# Setting Up CloudTrail Multi-Region

## Overview

Domain expertise for enabling AWS CloudTrail across all regions to capture
comprehensive API activity logs and configuring CloudWatch Logs Insights for
security monitoring, compliance auditing, and operational analysis.

## Set up a multi-region trail

To create a centralized multi-region CloudTrail trail with S3 storage, CloudWatch
Logs integration, and log analysis, follow the procedure exactly.
See [CloudTrail multi-region setup procedure](references/cloudtrail-multi-region-setup.md).

## Troubleshooting

### S3 bucket already exists

Choose a different globally unique name, or add a timestamp or organization identifier.

### Permission denied errors

Verify your identity with `aws sts get-caller-identity`. Ensure your user/role has required actions attached. Do NOT use `*FullAccess` managed policies.

### Trail not logging

Verify IAM role permissions, check S3 bucket policy allows CloudTrail access, and ensure the trail is started with `start-logging`.

### Missing events in CloudWatch

Allow 5-15 minutes for initial log delivery. Verify the CloudWatch Logs role ARN is correct and the log group exists in the same region as the trail.

### Opt-in region events not appearing

This is normal — events from opt-in regions may take several hours. Wait up to 24 hours before investigating further.
