Umbraco Quickstart Sets up everything needed for Umbraco extension development in one command. Usage
Full setup with custom credentials
/umbraco-quickstart MyUmbracoSite MyExtension --email a@a.co.uk --password Admin123456
With default credentials (admin@test.com / SecurePass1234)
/umbraco-quickstart MyUmbracoSite MyExtension
Just Umbraco instance name (will prompt for extension name)
/umbraco-quickstart MyUmbracoSite
No arguments (will detect existing or prompt for names)
- /umbraco-quickstart
- Workflow
- 1. Parse arguments
- First argument
-
- Umbraco project name (e.g., "MyUmbracoSite")
- Second argument
- Extension name (e.g., "MyExtension")
--email
(optional): Admin email (default:
admin@test.com
)
--password
(optional): Admin password (default:
SecurePass1234
)
If arguments not provided, check what exists and prompt for missing names.
2. Check what exists
Check for Umbraco instance:
find
.
-name
"*.csproj"
-exec
grep
-l
"Umbraco.Cms"
{
}
\
;
2
/dev/null | head -5 Check for extension projects: find . -name "umbraco-package.json" 2
/dev/null | head -10 3. Take action If no Umbraco instance: Use the provided name (first argument) or prompt for one Create with /package-script-writer [ProjectName] If no extension: Use the provided name (second argument) or prompt for one Create with /umbraco-extension-template [ExtensionName] If extension not registered: Register with /umbraco-add-extension-reference [ExtensionName] 4. Warn about optional resources Check extended workspace (including /add-dir directories) and warn if missing: If CMS source not found: ⚠ Umbraco CMS source not found in extended workspace. For better code generation, add it: git clone https://github.com/umbraco/Umbraco-CMS.git /add-dir /path/to/Umbraco-CMS/src/Umbraco.Web.UI.Client If UUI source not found: ⚠ UUI library source not found in extended workspace. For UI component reference, add it: git clone https://github.com/umbraco/Umbraco.UI.git /add-dir /path/to/Umbraco.UI/packages/uui If testing skills not installed: ⚠ Testing skills not installed. To add testing capabilities: /plugin install umbraco-cms-backoffice-testing-skills@umbraco-backoffice-marketplace 5. MANDATORY: Enter Plan Mode Do NOT proceed to building until this step is complete. Tell the user setup is complete and show the login credentials Read PRE-BUILD-PLANNING.md from the umbraco-backoffice skill Ask the user what they want to build ✅ Setup complete! Your extension is ready. Login: admin@test.com / SecurePass1234 What would you like to build? Describe your idea and I'll help you plan the implementation. Examples: - "A dashboard that shows recent content changes" - "A property editor for picking colours" - "A tree in Settings for managing custom data" When the user describes what they want: Enter plan mode with /plan Follow the PRE-BUILD-PLANNING.md workflow: Draw ASCII wireframe of the UI Label extension types needed (section, dashboard, workspace, etc.) Identify UUI components Map data flow (contexts, APIs) Identify which sub-skills to invoke Include these MANDATORY sections in the plan document (they will be actioned after plan approval):
Pre-Build Setup
[ ] Load
/umbraco-backoffice
skill for best practices and examples
Implementation [Your implementation steps here - skills to invoke, files to create]
Post-Build Validation (REQUIRED - DO NOT SKIP)
Step 1: Initial Build
[ ] Run
npm run build
in extension directory
-
[ ] Verify build completes without errors
Step 2: Code Review
[ ] Spawn
umbraco-extension-reviewer
agent
-
[ ] Fix all Critical/High severity issues
Step 3: Rebuild (if fixes were made)
[ ] Run
npm run build
again
-
[ ] Verify build still succeeds
Step 4: Restart Umbraco
[ ] Stop the running Umbraco instance
[ ] Run
dotnet run
to restart
-
[ ] Wait for startup to complete
Step 5: Browser Validation
Check if browser automation is available (any of:
dev-browser
skill, Playwright MCP, Claude computer use).
If browser automation IS available:
-
[ ] Navigate to backoffice login (http://localhost:5000/umbraco)
-
[ ] Login with credentials
-
[ ] Navigate to extension location
-
[ ] Verify: no console errors, UI renders, interactions work
-
[ ] Take screenshot of working extension
If NO browser automation available, output manual testing steps for user.
Exit plan mode only when wireframe AND all validation sections are in the plan
⚠️ Do NOT generate code until planning is complete and approved by the user.
Goal
Get the user to a working, validated extension. Follow the workflow: PLAN → BUILD → VALIDATE. Don't just report - take action.
Default Credentials
When creating an Umbraco instance, these defaults are used:
Email:
admin@test.com
Password:
SecurePass1234
These are safe for local development and don't contain special characters that cause escaping issues.
Example
/umbraco-quickstart MyUmbracoSite MyDashboard
This will:
Create Umbraco instance (e.g. "MyUmbracoSite") if not exists
Create extension (e.g. "MyDashboard")
Register the extension with the Umbraco project
Warn about missing CMS/UUI source if applicable
Enter plan mode to design the extension (wireframe, extension types, validation steps)
Build using identified sub-skills
Run
npm run build
Run
umbraco-extension-reviewer
and fix issues
Rebuild if fixes were made
Restart Umbraco
Browser validation (automatic if browser automation available, manual steps otherwise)
