Setup Auth

Plugin check: Run node "${CLAUDE_PLUGIN_ROOT}/scripts/check-version.js" — if it outputs a message, show it to the user before proceeding.

Set Up Authentication & Authorization

Configure authentication (login/logout via Microsoft Entra ID) and role-based authorization for a Power Pages code site. This skill creates an auth service, type declarations, authorization utilities, auth UI components, and role-based access control patterns appropriate to the site's framework.

Core Principles

• Client-side auth is UX only — Power Pages authentication is server-side (session cookies). Client-side role checks control what users see, not what they can access. Server-side table permissions enforce actual security.
• Framework-appropriate patterns — Every auth artifact (hooks, composables, services, directives, guards) must match the detected framework's idioms and conventions.
• Development parity — Include mock data for local development so developers can test auth flows and role-based UI without deploying to Power Pages.

Initial request: $ARGUMENTS

Prerequisites:

• An existing Power Pages code site created via /create-site
• The site must be deployed at least once (.powerpages-site folder must exist)
• Web roles must be created via /create-webroles

Workflow

1. Phase 1: Check Prerequisites — Verify site exists, detect framework, check web roles
2. Phase 2: Plan — Gather auth requirements and present plan for approval
3. Phase 3: Create Auth Service — Auth service with login/logout and type declarations
4. Phase 4: Create Authorization Utils — Role-checking functions and wrapper components
5. Phase 5: Create Auth UI — Login/logout button integrated into navigation
6. Phase 6: Implement Role-Based UI — Apply role-based patterns to site components
7. Phase 7: Verify Auth Setup — Validate all auth files exist, build succeeds, auth UI renders
8. Phase 8: Review & Deploy — Summary and deployment prompt

Phase 1: Check Prerequisites

Goal: Confirm the project exists, identify the framework, verify deployment status and web roles, and check for existing auth code.

Actions

1.1 Locate Project

Look for powerpages.config.json in the current directory or immediate subdirectories:

**/powerpages.config.json

If not found: Tell the user to create a site first with /create-site.

1.2 Detect Framework

Read package.json to determine the framework (React, Vue, Angular, or Astro). See ${CLAUDE_PLUGIN_ROOT}/references/framework-conventions.md for the full framework detection mapping.

1.3 Check Deployment Status

Look for the .powerpages-site folder:

**/.powerpages-site

If not found: Tell the user the site must be deployed first:

"The .powerpages-site folder was not found. The site needs to be deployed at least once before authentication can be configured."

Use AskUserQuestion:

If "Yes, deploy now": Invoke /deploy-site, then resume.

If "No": Stop — the site must be deployed first.

1.4 Check Web Roles

Look for web role YAML files in .powerpages-site/web-roles/:

**/.powerpages-site/web-roles/*.yml

Read each file and compile a list of existing web roles (name, id, flags).

If no web roles exist: Warn the user that web roles are needed for authorization. Ask if they want to create them first:

If "Yes": Invoke /create-webroles, then resume.

If "Skip": Continue — auth service and login/logout will still work, but role-based authorization will need roles created later.

1.5 Check for Existing Auth Code

Search for existing auth files to avoid duplicating work:

• src/services/authService.ts or src/services/authService.js
• src/types/powerPages.d.ts
• src/utils/authorization.ts or src/utils/authorization.js
• Auth components (e.g., AuthButton.tsx, AuthButton.vue)

If auth files already exist, present them to the user and ask whether to overwrite or skip.

Output

• Project root path confirmed
• Framework identified (React, Vue, Angular, or Astro)
• Deployment status verified
• Web roles inventory compiled
• Existing auth code conflicts identified (if any)

Phase 2: Plan

Goal: Gather authentication requirements from the user and present the implementation plan for approval.

Actions

2.1 Gather Requirements

Use AskUserQuestion to determine the scope:

If web roles were found in Phase 1.4, also ask:

2.2 Present Plan for Approval

Present the implementation plan inline:

• Which files will be created (auth service, types, authorization utils, components)
• How the auth UI will be integrated into the site's navigation
• Which routes/components will be protected and with which roles
• The site setting that needs to be configured (Authentication/Registration/ProfileRedirectEnabled = false)

Use AskUserQuestion to get approval:

If "Approve and proceed": Continue to Phase 3.

If "I'd like to make changes": Ask the user what they want to change, revise the plan, and present it again for approval.

Output

• Authentication scope confirmed (login/logout, role-based access, or both)
• Target web roles selected
• Implementation plan approved by user

Phase 3: Create Auth Service

Goal: Create the authentication service, type declarations, and framework-specific auth hook/composable with local development mock support.

Reference: ${CLAUDE_PLUGIN_ROOT}/skills/setup-auth/references/authentication-reference.md

Actions

3.1 Create Type Declarations

Create src/types/powerPages.d.ts with type definitions for the Power Pages portal object and user:

• PowerPagesUser interface — userName, firstName, lastName, email, contactId, userRoles[]
• PowerPagesPortal interface — User, version, type, id, geo, tenant, etc.
• Global Window interface extension for Microsoft.Dynamic365.Portal

3.2 Create Auth Service

Create the auth service file based on the detected framework:

All frameworks: Create src/services/authService.ts with these functions:

• getCurrentUser() — reads from window.Microsoft.Dynamic365.Portal.User
• isAuthenticated() — checks if user exists and has userName
• getTenantId() — reads from portal config (window.Microsoft.Dynamic365.Portal.tenant)
• fetchAntiForgeryToken() — fetches from /_layout/tokenhtml and parses HTML response
• login(returnUrl?) — creates a form POST to /Account/Login/ExternalLogin with:
  • Anti-forgery token from /_layout/tokenhtml
  • Provider URL: https://login.windows.net/{tenantId}/
  • Return URL (defaults to current page)
• logout(returnUrl?) — redirects to /Account/Login/LogOff
• getUserDisplayName() — prefers full name, falls back to userName
• getUserInitials() — for avatar display

CRITICAL: Power Pages authentication is server-side (session cookies). The login flow posts a form to the server which redirects to Entra ID. There is no client-side token management. The fetchAntiForgeryToken() call gets a CSRF token for the form POST, not a bearer token.

3.3 Create Framework-Specific Auth Hook/Composable

Based on the detected framework:

• React: Create src/hooks/useAuth.ts — custom hook returning { user, isAuthenticated, isLoading, displayName, initials, login, logout, refresh }
• Vue: Create src/composables/useAuth.ts — composable using ref, computed, onMounted returning reactive auth state
• Angular: Create src/app/services/auth.service.ts — injectable service with BehaviorSubject for user state
• Astro: Create src/services/authService.ts only (no framework-specific wrapper needed — use the service directly in components)

3.4 Add Mock Data for Local Development

Auth only works when served from Power Pages (not during local npm run dev). Add a development mock pattern in the auth service:

// In development (localhost), return mock user data for testing
const isDevelopment = window.location.hostname === 'localhost' || window.location.hostname === '127.0.0.1';

The mock should return a fake user with configurable roles so developers can test role-based UI locally.

Output

• src/types/powerPages.d.ts created with Power Pages type definitions
• src/services/authService.ts created with login/logout functions
• Framework-specific auth hook/composable created
• Local development mock data included

Phase 4: Create Authorization Utils

Goal: Create role-checking utilities and framework-specific authorization components (guards, directives, wrapper components).

Reference: ${CLAUDE_PLUGIN_ROOT}/skills/setup-auth/references/authorization-reference.md

Actions

4.1 Create Core Authorization Utilities

Create src/utils/authorization.ts with:

• getUserRoles() — returns array of role names from current user
• hasRole(roleName) — case-insensitive single role check
• hasAnyRole(roleNames) — OR check across multiple roles
• hasAllRoles(roleNames) — AND check across multiple roles
• isAuthenticated() — re-exports from auth service
• isAdmin() — checks for "Administrators" role
• hasElevatedAccess(additionalRoles) — checks admin or specified roles

4.2 Create Framework-Specific Authorization Components

Based on the detected framework:

React:

• src/components/RequireAuth.tsx — renders children only for authenticated users, optional login prompt fallback
• src/components/RequireRole.tsx — renders children only for users with specified roles, supports requireAll mode
• src/hooks/useAuthorization.ts — hook returning { roles, hasRole, hasAnyRole, hasAllRoles, isAuthenticated, isAdmin }

Vue:

• src/composables/useAuthorization.ts — composable with computed roles and role-checking functions
• src/directives/vRole.ts — v-role directive for declarative role-based visibility

Angular:

• src/app/guards/auth.guard.ts — CanActivateFn with route data for required roles
• src/app/directives/has-role.directive.ts — structural directive *appHasRole="'RoleName'"

Astro:

• src/utils/authorization.ts only (use directly in component scripts)

4.3 Security Reminder

Add a comment at the top of the authorization utilities:

// IMPORTANT: Client-side authorization is for UX only, not security.
// Server-side table permissions enforce actual access control.
// Always configure table permissions via /integrate-webapi.

Output

• src/utils/authorization.ts created with role-checking functions
• Framework-specific authorization components created (guards, directives, or wrapper components)
• Security reminder comments included

Phase 5: Create Auth UI

Goal: Create the login/logout button component and integrate it into the site's navigation.

Actions

5.1 Create Auth Button Component

Based on the detected framework, create a login/logout button component:

• React: src/components/AuthButton.tsx + src/components/AuthButton.css
• Vue: src/components/AuthButton.vue
• Angular: src/app/components/auth-button/auth-button.component.ts + template + styles
• Astro: src/components/AuthButton.astro

The component should:

• Show a "Sign In" button when the user is not authenticated
• Show the user's display name, avatar (initials-based), and a "Sign Out" button when authenticated
• Include a loading state while checking auth status
• Be styled to match the site's existing design (read existing CSS variables/theme)

5.2 Integrate into Navigation

Find the site's navigation component and integrate the auth button:

1. Search for the nav/header component in the site's source code
2. Import the AuthButton component
3. Add it to the navigation bar (typically in the top-right area)

Do NOT replace the existing navigation — add the auth button alongside existing nav items.

5.3 Git Commit

Stage and commit the auth files:

git add -A
git commit -m "Add authentication service and auth UI component"

Output

• Auth button component created for the detected framework
• Auth button integrated into the site's navigation
• Changes committed to git

Phase 6: Implement Role-Based UI

Goal: Identify protected content areas and apply role-based authorization patterns to the site's components.

Actions

6.1 Identify Protected Content

Analyze the site's components to find content that should be role-gated:

• Admin-only sections (dashboards, settings)
• Authenticated-only content (profile, data views)
• Role-specific features (edit buttons, create forms)

Present findings to the user and confirm which areas to protect.

6.2 Apply Authorization Patterns

Based on the user's choices, wrap the appropriate components:

React example:

<RequireAuth fallback={<p>Please sign in to view this content.</p>}>
  <Dashboard />
</RequireAuth>

<RequireRole roles={['Administrators']} fallback={<p>Access denied.</p>}>
  <AdminPanel />
</RequireRole>

Vue example:

<div v-role="'Administrators'">
  <AdminPanel />
</div>

Angular example:

{ path: 'admin', component: AdminComponent, canActivate: [authGuard, roleGuard], data: { roles: ['Administrators'] } }

6.3 Git Commit

Stage and commit:

git add -A
git commit -m "Add role-based access control to site components"

Output

• Protected content areas identified and confirmed with user
• Role-based authorization patterns applied to components
• Changes committed to git

Phase 7: Verify Auth Setup

Goal: Validate that all auth files exist, the project builds, and the auth UI renders correctly.

Actions

7.1 Verify File Inventory

Confirm the following files were created:

• src/types/powerPages.d.ts — Power Pages type declarations
• src/services/authService.ts — Auth service with login/logout functions
• Framework-specific auth hook/composable (e.g., src/hooks/useAuth.ts for React)
• src/utils/authorization.ts — Role-checking utilities
• Framework-specific authorization components (e.g., RequireAuth.tsx, RequireRole.tsx for React)
• Auth button component (e.g., src/components/AuthButton.tsx for React)

Read each file and verify it contains the expected exports and functions:

• Auth service: login, logout, getCurrentUser, isAuthenticated, fetchAntiForgeryToken
• Authorization utils: hasRole, hasAnyRole, hasAllRoles, getUserRoles

7.2 Verify Build

Run the project build to catch any import errors, type errors, or missing dependencies:

npm run build

If the build fails, fix the issues before proceeding.

7.3 Verify Auth UI Renders

Start the dev server and verify the auth button appears in the navigation:

npm run dev

Use Playwright to navigate to the site and take a snapshot to confirm the auth button is visible:

• Navigate to http://localhost:<port>
• Take a browser snapshot
• Verify the auth button (Sign In / mock user) appears in the navigation area

If the auth button is not visible or the page has rendering errors, fix the issues.

Output

• All auth files verified (present and contain expected exports)
• Project builds successfully
• Auth UI renders correctly in the browser

Phase 8: Review & Deploy

Goal: Create required site settings, present a summary of all work, and prompt for deployment.

Actions

8.1 Create Site Setting

The site needs the Authentication/Registration/ProfileRedirectEnabled setting set to false to prevent Power Pages from redirecting users to a profile page after login (which doesn't exist in code sites).

Check if .powerpages-site/site-settings/ exists. If it does, create the site setting file:

node "${CLAUDE_PLUGIN_ROOT}/scripts/generate-uuid.js"

Create .powerpages-site/site-settings/authentication-registration-profileredirectenabled.yml:

id: <UUID from generate-uuid.js>
name: Authentication/Registration/ProfileRedirectEnabled
value: false

8.2 Record Skill Usage

Reference: ${CLAUDE_PLUGIN_ROOT}/references/skill-tracking-reference.md

Follow the skill tracking instructions in the reference to record this skill's usage. Use --skillName "SetupAuth".

8.3 Present Summary

Present a summary of everything created:

8.4 Ask to Deploy

Use AskUserQuestion:

If "Yes, deploy now": Invoke /deploy-site.

If "No": Remind the user:

"Remember to deploy your site using /deploy-site when you're ready. Authentication will not work until the site is deployed with the new site settings."

8.5 Post-Deploy Notes

After deployment (or if skipped), remind the user:

• Test on deployed site: Auth only works on the deployed Power Pages site, not on localhost
• Entra ID configuration: The site's identity provider must be configured in the Power Pages admin center to use Microsoft Entra ID
• Assign web roles: Users must be assigned appropriate web roles in the Power Pages admin center
• Table permissions: Client-side auth checks are for UX only — configure server-side table permissions via /integrate-webapi for actual data security
• Local development: The auth service includes mock data for testing on localhost — remove or disable before production

Output

• ProfileRedirectEnabled site setting created
• Full summary presented to user
• Deployment prompted (or skipped with reminder)
• Post-deploy guidance provided

Important Notes

Progress Tracking

Use TaskCreate at the start to track each phase:

Update each task with TaskUpdate as phases are completed.

Key Decision Points

• Phase 1.3: Deploy now or stop? (site must be deployed before auth setup)
• Phase 1.4: Create web roles now or skip? (roles needed for authorization)
• Phase 1.5: Overwrite or skip existing auth files?
• Phase 2.1: Which auth features to include? (login/logout, role-based, or both)
• Phase 2.2: Approve plan or request changes?
• Phase 6.1: Which content areas to protect with role-based access?
• Phase 8.3: Deploy now or later?

Begin with Phase 1: Check Prerequisites
