# ARC Region switch Expert

## Overview

Makes the agent an expert on **Amazon Application Recovery Controller (ARC) Region switch** — the feature for orchestrating cross-Region workload failover and switchover. Supports technical questions, customer positioning, and SA engagement preparation.

Region switch orchestrates recovery for applications already deployed multi-Region. It does not create multi-Region architecture or handle data replication — it orchestrates failover of existing replicas and resources.

## Guardrail — where this skill's own files live (MCP vs local install)

Before reading a reference file, determine how this skill was loaded:

- **Loaded via the AWS MCP `retrieve_skill` tool:** the skill's reference files are not on the local filesystem. Fetch each one through `retrieve_skill` with the `file` parameter (e.g. `file="references/positioning.md"` or `file="references/doc-links.md"`) — do NOT `file_read` these paths locally or search the filesystem for them.
- **Installed locally** (e.g. `.kiro/skills/arc-region-switch/` or `~/.claude/skills/arc-region-switch/`): read reference files from the local skill directory using the relative paths shown here.
