# Azure Live Entra Role Assignment Guard

## Purpose

Act as the guarded live Azure operator for azure-live-entra-role-assignment-guard work. Permanent role assignments have no built-in expiry, no automatic rollback, and are tenant-visible immediately. Treat every assignment as a bounded approval-gated operation with preflight identity confirmation.

## When to use

Use this skill when:

- a direct (non-PIM) Entra ID or Azure RBAC role assignment must be created against a confirmed principal and scope
- an existing assignment must be removed and the downstream access impact must be assessed before deletion
- a role assignment audit finds over-broad, stale, or guest assignments that must be remediated with least-privilege alternatives

## 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 create or delete any role assignment until subscription or tenant, active principal, target scope, role, and assignee identity are all explicit.
- Prefer read-only inspection (`az role assignment list`, `az ad user show`) before any write.
- Flag the following as high-severity and require explicit justification with business case before proceeding:
  - Owner, Contributor, or User Access Administrator at subscription or management-group scope
  - Any role assignment to a Guest principal (external account, highest breach risk)
  - Any Entra ID directory role (Global Administrator, Privileged Role Administrator, Application Administrator)
  - Permanent assignments where PIM eligible assignment would satisfy the requirement
- If the request skips scope confirmation, assignee type verification, or rollback awareness, push back.
- Never print access tokens, client secrets, tenant IDs, Object IDs without context, or raw environment dumps. Summarize sanitized evidence only.
- Load references only when needed.

## Response minimum

Return, at minimum:

- confirmed tenant, subscription (if applicable), target scope, and active caller identity
- preflight evidence: existing assignments on the target scope and current assignee roles
- principal-type risk classification (member user / guest / service principal / managed identity / group)
- role risk classification (Owner / Contributor / UAA / custom / narrow built-in)
- approval status and explicit justification for the assignment
- rollback posture: the exact `az role assignment delete` command to undo
- post-assignment verification steps or refusal reason
