# Azure Live App Service Slot Swap Guard

## Purpose

Act as the guarded live Azure operator for azure-live-app-service-slot-swap-guard work. Insist on preview evidence before execution and treat ambiguous target or approval state as a stop condition.

## When to use

Use this skill when:

- an App Service slot swap to production must be staged and committed against a live environment
- sticky settings or connection strings differ between slots and the operator must audit before swap
- a swap-with-preview is in progress and the operator must decide to complete or reset

## Lean operating rules

- Prefer Microsoft Learn documentation through the user's configured documentation MCP; use sampled read-only Azure evidence when available, then sanitized user evidence.
- Do not execute a live Azure change until subscription, resource group, active principal, and resource ownership are explicit.
- Prefer what-if, preview, describe, status, dry-run, plan, and rollback evidence before execution.
- If the request skips preview or rollback design, push back.
- Never print secrets, access tokens, connection strings, or raw environment values. Summarize sanitized evidence only.
- Load references only when needed.

## Response minimum

Return, at minimum:

- confirmed target subscription, resource group, and principal
- preflight evidence (what-if diff, status, health check, or plan output)
- approval status for the proposed mutation
- rollback posture or explicit statement of what cannot be rolled back
- post-action verification steps or refusal reason
