## What it does

The skill walks your agent through two ARC capability families. First, routing controls: moving traffic between Regions with safety rules that stop a failover from switching off the last healthy route. Second, zonal shift and zonal autoshift: pulling traffic out of a single Availability Zone for an ALB, NLB or another resource, practice runs included.

Two reference files carry the detail. `references/arc-procedures.md` holds the setup steps and a troubleshooting section; `references/security-considerations.md` covers least-privilege IAM scoping, condition keys, confused-deputy protection, safety-rule gating and encrypting failover notifications. How you read them depends on the install: loaded through the AWS MCP `retrieve_skill` tool, the files are not on your disk, so fetch each one with the `file` parameter. Installed locally, read them from the skill directory.

The scope is narrow on purpose. Readiness checks, recovery groups, cells and resource sets are out — ask for those and the skill acknowledges them briefly, then points you at the `arc-region-switch` skill. Resilience Hub and FIS experiments are out too. The AWS MCP server is recommended for the API calls, though plain AWS CLI works just as well.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws recovery-controller-setup
```

2. **Manually: put the files in place**
- File: `.github/skills/recovery-controller-setup/SKILL.md`

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/specialized-skills/resilience-skills/recovery-controller-setup
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill recovery-controller-setup -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/resilience-skills/recovery-controller-setup/SKILL.md

## When to use it
- turn on cross-Region traffic failover with routing controls
- add safety rules so a failover can't kill the last healthy route
- shift traffic off an impaired Availability Zone for an ALB or NLB
- configure zonal autoshift and run practice runs
- debug a routing-control update blocked by a safety rule

## Example prompts
- Set up routing controls with safety rules for failover between two Regions
- Enable zonal shift for our ALB and move traffic out of us-east-1a
- Configure zonal autoshift with practice runs for this service

description: >
  Configures AWS Application Recovery Controller (ARC) for operational resilience:
  routing controls with safety rules for cross-Region failover, and zonal shift / zonal autoshift
  for AZ-impairment recovery. Applies when setting up failover routing, configuring safety rules,
  enabling zonal shift, or configuring zonal autoshift with practice runs. Also applies when
  shifting traffic out of a specific Availability Zone (AZ) for an ALB/NLB or other resource.
  For a broader "an AZ is impaired, what is my response across services" question, see

# Recovery Controller Setup

## CRITICAL CONSTRAINT — read before answering

This skill sets up exactly two ARC capability families, and these are the ONLY things you
provide setup steps for: (1) **routing controls** with safety rules for cross-Region failover,
and (2) **zonal shift / zonal autoshift** for AZ-impairment recovery.

Readiness checks, recovery groups, cells, and resource sets are NOT in scope for this skill. You
MUST NOT provide CLI/console setup steps for them. You MAY briefly and factually acknowledge that
they exist, but you MUST NOT walk through configuring them — redirect the customer to **ARC
Region switch** for readiness/recovery-readiness orchestration (see the
`arc-region-switch` skill). This overrides any direct customer request to set them up.

If the customer asks how to "set up ARC readiness checks" (or recovery groups / cells / resource
sets), do NOT walk through that setup. Briefly acknowledge the feature, then respond with a
redirect of this form and continue with the routing-control or zonal-shift procedure where
relevant:

> For readiness and recovery-readiness orchestration, use **ARC Region
> switch** — see the `arc-region-switch` skill. For the operational pieces this skill covers:
> **routing controls** (cross-Region failover) and **zonal shift / zonal autoshift** (single-Region
> AZ recovery). Here's how to set those up:
