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.

References

Load these only when needed:

• Azure Entra and RBAC Role Assignment Operations — use for current service behavior, common failure modes, hard design rules, verification targets, and push-back conditions.
• Preflight commands — CLI commands to run before any mutation.
• Rollback playbook — concrete rollback steps for this service.
• Permission model — RBAC role definitions and PIM guidance.
• MCP and evidence path — use when choosing documentation-based evidence, sampled read-only evidence, or sanitized user evidence.
• Safety checklist — use for evidence labels, permanent assignment blast radius, PIM eligibility, guest/service-principal risk, propagation delay, and rollback limits.
• Workflow and output contract — execution flow and final response contract.
• Official sources — authoritative Azure documentation links.

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
