Set App Registration Native

Wire auth.config.json to an Entra ID app registration for a Power Apps Wrap mobile app.

This skill is manual by design:

• Do not create or patch app registrations from this skill.
• Use the public Power Apps Wrap app-registration page to create/configure the registration, then write the pasted client ID into auth.config.json.
• Do not direct the user to add redirect URIs or API permissions manually. Tenant-wide admin consent is not required for this Wrap registration flow.

Workflow

1. Verify app root -> 2. Resolve environment + tenant -> 3. Open Wrap registration URL -> 4. Capture client ID -> 5. Write auth.config.json -> 6. Validate JSON -> 7. Summary

Step 1 — Verify app root

From the current directory, verify a generated mobile app root:

bashCopy code
test -f auth.config.json && test -f app.config.js && test -f power.config.json

If this fails, stop and tell the user to run /create-mobile-app first or open the generated app folder.

Step 2 — Resolve environment + tenant

Telemetry checkpoint: resolve_registration_environment

Use the same environment selected by the generated app. Prefer .resolved-environment.json, then auth.config.json.environment, then power.config.json + resolver:

bashCopy code
ENV_ID=$(node -e "console.log(require('./power.config.json').environmentId || '')")
TENANT_ID=$(node -e "try { const j=require('./.resolved-environment.json'); console.log(j.tenantId || '') } catch { console.log('') }" 2>/dev/null)
if [ -z "$TENANT_ID" ]; then
  TENANT_ID=$(node -e "try { const j=require('./auth.config.json'); console.log((j.environment && j.environment.tenantId) || '') } catch { console.log('') }" 2>/dev/null)
fi
if [ -z "$TENANT_ID" ] && [ -n "$ENV_ID" ]; then
  node "${PLUGIN_ROOT}/scripts/resolve-environment.js" "$ENV_ID" > .resolved-environment.json
  TENANT_ID=$(node -e "const j=require('./.resolved-environment.json'); console.log(j.tenantId || '')")
fi
echo "$ENV_ID"
echo "$TENANT_ID"

If ENV_ID is empty, stop: power.config.json is not initialized.

If TENANT_ID is empty, stop: environment resolution failed. Do not guess the tenant and do not use a stale msal.tenantId as the authority source.

Step 3 — Open Wrap app-registration page

Telemetry checkpoint: open_wrap_app_registration

Print the public Power Apps Wrap URL for the active environment:

textCopy code
https://make.powerapps.com/environments/<environment-id>/wraps#create-app-registration

Tell the user:

textCopy code
Open the Power Apps Wrap app-registration page for this environment:
https://make.powerapps.com/environments/<environment-id>/wraps#create-app-registration

Create/register the app there, then paste the Application (client) ID here.
The Wrap page configures the native registration. Do not add redirect URIs or
API permissions manually; tenant-wide admin consent is not required.
If you already have a client ID, paste it directly.
If you cannot configure auth now, type skip.

Step 4 — Capture client ID

Ask:

textCopy code
Paste the Entra ID app registration client ID for tenant <tenant-guid> (GUID format), or type skip:

• If the user enters skip, leave msal.clientId blank, ensure msal.tenantId is set to the resolved tenant, preserve/add the environment cache, print the skip warning in Step 7, and stop.
• Otherwise validate GUID format before editing.

Step 5 — Write auth.config.json

Telemetry checkpoint: write_native_auth_configuration

Update auth.config.json:

• msal.clientId = pasted client ID
• msal.tenantId = resolved tenant ID from Step 2
• Preserve any top-level environment object.
• If environment is missing and .resolved-environment.json exists, copy the non-secret resolved environment fields into top-level environment.

Use structured JSON editing. Do not store tokens, secrets, or current-user Dataverse identity fields.

Example target shape:

jsonCopy code
{
  "msal": {
    "clientId": "<client-id>",
    "tenantId": "<tenant-guid>"
  },
  "environment": {
    "environmentId": "<environment-id>",
    "environmentUrl": "https://org.crm.dynamics.com",
    "tenantId": "<tenant-guid>",
    "cachedAt": "<iso timestamp>"
  }
}

Do not touch src/playerConfig.ts; auth identifiers live in auth.config.json only.

Step 6 — Validate JSON

Telemetry checkpoint: validate_native_auth_configuration

bashCopy code
node -e "JSON.parse(require('fs').readFileSync('auth.config.json','utf8')); console.log('auth.config.json OK')"

If dependencies are installed, optionally run:

bashCopy code
npx tsc --noEmit

Do not run npm install or native builds from this skill.

Step 7 — Summary

If a client ID was written:

textCopy code
App registration wired.
Client ID : <client-id>
Tenant    : <tenant-guid>
Config    : auth.config.json

If skipped:

textCopy code
Auth client ID was not configured.
Tenant was preserved in auth.config.json: <tenant-guid>
The app will fail to sign in until a client ID is added.
Run /set-app-registration-native later, or paste a client ID into auth.config.json.
