| Delegate | Assign to another reviewer | Reviewer cannot certify |
| Escalate | Request security review | Anomaly detected |

## Execution Flow

### Step 1: Generate Access Report
```tool
iam.get_access_report({
  scope: "{scope}",
  reviewType: "{reviewType}",
  includeEntitlements: true,
  includeLastUsed: true,
  includeRiskScores: true
})
```

### Step 2: Get User Entitlements
```tool
iam.get_entitlements({
  userId: "{userId}",
  includeGroups: true,
  includeRoles: true,
  includeApplications: true,
  includePermissions: true
})
```

### Step 3: Check Employment Status
```tool
hr.get_employee_status({
  userId: "{userId}",
  includeJobHistory: true,
  includeDepartment: true,
  includeManager: true
})
```

### Step 4: Send Review Request
```tool
messaging.send_review_request({
  to: "{reviewerId}",
  template: "access_review",
  data: {
    reviewId: "{reviewId}",
    usersToReview: "{user_count}",
    dueDate: "{due_date}",
    reviewLink: "{link}"
  }
})
```

### Step 5: Certify Access
```tool
iam.certify_access({
  reviewId: "{reviewId}",
  userId: "{userId}",
  entitlements: "{entitlements}",
  action: "certify",
  certifiedBy: "{reviewerId}",
  justification: "{justification}"
})
```

### Step 6: Revoke Access
```tool
iam.revoke_access({
  userId: "{userId}",
  entitlements: "{entitlements_to_revoke}",
  reason: "access_review",
  reviewId: "{reviewId}",
  revokedBy: "{reviewerId}"

## Guardrails

- Never auto-certify access without human review
- Require justification for all certifications
- Escalate unresponsive reviewers to management
- Automatically revoke terminated employee access
- Flag unused access for mandatory review
- Document all certification decisions
- Maintain complete audit trail
- Alert on privileged access changes
- Enforce review deadlines with escalation
- Never allow self-certification of access
