## TL;DR

IAM policy simulators and access troubleshooters let agents explain permission failures before widening privileges.

## Core Explanation

Permission errors are easy to misdiagnose. A denied request may be caused by a missing allow, an explicit deny, a resource policy, a boundary, an organization rule, a condition expression, or the wrong identity. Agents need policy evaluation evidence before proposing broader access.

For safe remediation, the agent should cite the principal, resource, action, policy source, and simulator or troubleshooter result. The least risky fix is usually a narrow permission change tied to a tested request, not a broad admin role.
