## Quick Start

### Run a Security Audit

```powershell
Connect-MgGraph -Scopes "Directory.Read.All","Policy.Read.All","AuditLog.Read.All"
Get-MgSubscribedSku | Select-Object SkuPartNumber, ConsumedUnits, @{N="Total";E={$_.PrepaidUnits.Enabled}}
Get-MgPolicyAuthorizationPolicy | Select-Object AllowInvitesFrom, DefaultUserRolePermissions
```

### Bulk Provision Users from CSV

```powershell
# CSV columns: DisplayName, UserPrincipalName, Department, LicenseSku
Import-Csv .\new_users.csv | ForEach-Object {
    $passwordProfile = @{ Password = (New-Guid).ToString().Substring(0,16) + "!"; ForceChangePasswordNextSignIn = $true }
    New-MgUser -DisplayName $_.DisplayName -UserPrincipalName $_.UserPrincipalName `
               -Department $_.Department -AccountEnabled -PasswordProfile $passwordProfile
}
```

### Create a Conditional Access Policy (MFA for Admins)

```powershell
$adminRoles = (Get-MgDirectoryRole | Where-Object { $_.DisplayName -match "Admin" }).Id
$policy = @{
    DisplayName = "Require MFA for Admins"
    State = "enabledForReportingButNotEnforced"   # Start in report-only mode
    Conditions = @{ Users = @{ IncludeRoles = $adminRoles } }
    GrantControls = @{ Operator = "OR"; BuiltInControls = @("mfa") }
}
New-MgIdentityConditionalAccessPolicy -BodyParameter $policy
```

### Bundled Python Generators

Three stdlib tools generate the PowerShell artifacts deterministically — prefer them over hand-writing scripts for bulk/repeatable work. Sample input: `sample_input.json`; expected shape: `expected_output.json`.

```bash
# Tenant setup: checklist + DNS records + license plan (JSON), or the full setup script
python3 scripts/tenant_setup.py --config sample_input.json --format json -o tenant_plan.json
python3 scripts/tenant_setup.py --config sample_input.json --format powershell -o tenant_setup.ps1

# User lifecycle: validate first, then generate creation/offboarding scripts
python3 scripts/user_management.py --domain acme.com --action validate --users users.json
python3 scripts/user_management.py --domain acme.com --action create --users users.json -o create_users.ps1
python3 scripts/user_management.py --domain acme.com --action offboard --user-email [email protected] -o offboard.ps1

# Admin scripts: CA policy / security audit / bulk licensing
python3 scripts/powershell_generator.py --tenant-domain acme.com --task conditional-access --policy-config policy.json -o ca_policy.ps1
python3 scripts/powershell_generator.py --tenant-domain acme.com --task security-audit -o audit.ps1
python3 scripts/powershell_generator.py --tenant-domain acme.com --task bulk-license --users-csv users.csv --license-sku ENTERPRISEPACK -o licenses.ps1
```

**Gate:** for user creation, run `--action validate` first and require every entry to report `"is_valid": true` before generating the creation script. Review every generated `.ps1` against the workflows below before running it in the tenant.

## Workflows

### Workflow 1: New Tenant Setup

**Step 1: Generate Setup Checklist**

Run `python3 scripts/tenant_setup.py --config tenant.json --format json` and work through `setup_checklist` phase by phase; `dns_records` feeds Step 2 and `license_recommendations` feeds the licensing workflow.

Confirm prerequisites before provisioning:
