Experience Lwr Site Generate

Experience LWR Site Builder

Build and configure Salesforce Experience Cloud Lightning Web Runtime (LWR) sites via metadata (DigitalExperienceConfig, DigitalExperienceBundle, Network, CustomSite, CMS contents).

IMPORTANT!!

Right after loading this skill, you MUST copy the selected workflows/steps to your plan as a TODO checklist and work on each of the item carefully to ensure correctness. You MUST load the relevant reference docs even though they may live outside of user's project folder.

When to Use

When working with Experience LWR sites:

• Creating and scaffolding new LWR site
• Adding pages (routes + views)
• Configuring LWC components, layouts, themes, or branding styles
• Setting up guest user access (public sites)
• Creating or modifying guest sharing rules (sharingGuestRules) for any Salesforce object (Account, Case, Contact, etc.) — including when the user refers to a "Site Guest User" username or any guest user by ID
• Troubleshoot deployment errors related to Experience LWR Sites

Supported Template: Build Your Own (LWR) - talon-template-byo

• More templates to support in the future.

Critical Rules

1. Before using any MCP tool, make sure they're actually available. If a tool is missing for the current task, let the user know and pause the current workflow.
2. MUST ALWAYS load the relevant reference docs before doing anything.
3. MUST ALWAYS strictly follow workflows in Common Workflows that match user's requirements. The instructions there should override any conflicting global rules and should have the highest priority over your existing knowledge.
4. Flexipage is abstracted away for newer LWR sites with DigitalExperienceBundle, so NEVER use any Flexipage-related MCP tool or skills to handle LWR sites' contents.

Core Site Properties

Before doing anything else, note down the following properties from the local project if available as they will be used for various operations. Check with the user if any of the following is missing:

• Site name: Required. (e.g., 'My Community').
• URL path prefix: Optional. Alphanumeric characters only. Convert from site name if not provided (e.g., 'mycommunity') and verify with the user for the converted value.
• Template type devName: talon-template-byo.

Project Structure in DigitalExperienceBundle Format

Site Metadata

• DigitalExperienceConfig
  • digitalExperienceConfigs/{siteName}1.digitalExperienceConfig-meta.xml
• DigitalExperienceBundle
  • digitalExperiences/site/{siteName}1/{siteName}1.digitalExperience-meta.xml
• Network
  • networks/{siteName}.network-meta.xml
• CustomSite
  • sites/{siteName}.site-meta.xml

DigitalExperience Contents

• digitalExperiences/site/{siteName}1/sfdc_cms__*/{contentApiName}/*
• These are the content components defining routes, views, theme layouts, etc. Each component must have a _meta.json and content.json file.

Content Type Descriptions

Important: Creating any new pages require BOTH sfdc_cms__route AND sfdc_cms__view.

Object Pages

Object Pages are dedicated pages used to display and manage record-level data for a specific Salesforce entity/object. For example, an custom object "Car" should have "Car_Detail", "Car_List", and "Car_Related_list" views.

Common Workflows

• See References for detailed capabilities.
• Always follow the steps defined in the workflows sequentially whether the task is small, big, quick, or complex.

Creating a New Site

Rules:

• NEVER generate the files manually.

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• ALWAYS read bootstrap-template-byo-lwr.md [blocked] within the skill directory. Do not proceed to the next step without loading the file.
• Follow the bootstrap doc strictly on site creation

Creating and Editing Standard or Object Pages

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• MUST read configure-content-route.md [blocked]
• MUST read configure-content-view.md [blocked]
• MUST read handle-component-and-region-ids.md [blocked]

Adding UI Components to Pages

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• MUST read handle-ui-components.md [blocked] to add LWCs to LWR sites.
• MUST read handle-component-and-region-ids.md [blocked] to handle id generation
• MUST read configure-content-themeLayout.md [blocked] if a component has one of the following requirements:
  • needs to be "sticky" and persistent across pages
  • is used as a theme layout

Creating Page Layouts / Container Components

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• MUST read handle-ui-components.md [blocked]

Creating Theme Layouts

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• CRITICAL:Before doing anything else, MUST Check with user whether this new theme layout reuses an existing theme layout Lightning web component or requires a new one. If it requires a new one, make sure to read handle-ui-components.md [blocked] to create the new theme layout component before proceeding. DO NOT skip this step even if doing so would be faster or more efficient.
• MUST read configure-content-themeLayout.md [blocked].
• MUST read configure-content-view.md [blocked] if need to apply theme layout to pages

Applying/Setting Theme Layouts

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• MUST read configure-content-view.md [blocked]

Configuring Branding

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• MUST read configure-content-brandingSet.md [blocked] to configure background colors, foreground colors, button colors, and other branding colors that affect all pages.

CUD Operations on DigitalExperience Contents

• Users can perform create, update, delete operations on DigitalExperience Contents.

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• Determine what content types the user wants to modify
• MUST read the reference doc related to the target content types if the doc exists. e.g., if modifying sfdc_cms__route, load configure-content-route.md [blocked].
• MUST read handle-component-and-region-ids.md [blocked] if creating or modifying view or theme layout
• Always Call execute_metadata_action to get the schema and examples for that content type after loading the corresponding reference docs.
  • Call once per content type per user request: If you're creating/modifying multiple items of the same content type (e.g., creating 3 routes), you only need to call execute_metadata_action ONCE for that content type. Reuse the schema and examples for all items of that type within the same user request.
  • For each unique content type you need to work with, always call execute_metadata_action using the following:

{  "metadataType": "ExperienceSiteLwr",  "actionName": "getSiteContentMetadata",  "parameters": {    "contentType": "<content type from table above>",    "shouldIncludeExamples": true  }}

Configuring Guest User Sharing Rules

• MUST read configure-guest-sharing-rules.md [blocked] and follow all steps there.

Retrieving Site Preview and Builder URLs After Deployment

Use when user requests to preview a site, access a builder site, or after successfully deploying a site.

Use the execute_metadata_action MCP tool to get the preview and builder URLs:

{  "metadataType": "ExperienceSiteLwr",  "actionName": "getSiteUrls",  "parameters": {    "siteDevName": "<site developer name>"  }}

The site developer name can be found in the CustomSite filename (e.g., sites/MySite.site-meta.xml → developer name is MySite).

If the site is not found, an error message will be returned indicating that the site may not be deployed. Ensure the site has been successfully deployed before calling this action.

Updating Experience Site URLs

Use when user wants to update or change site URLs (urlPathPrefix).

Steps (Follow the steps sequentially. Do not skip any step before proceeding):

• MUST read update-site-urls.md [blocked] to understand the three-component architecture and URL update workflow
• Follow the step-by-step workflow in the doc to update URLs consistently across all three components (DigitalExperienceConfig, Network, CustomSite)

Validation & Deployment

Use sf CLI to validate and deploy. Access help docs by attaching --help, e.g.:

• sf project deploy --help
• sf project deploy validate --help

Note that metadata types are space-delimited. Never wrap them in quotes or use commas. For example, --metadata "DigitalExperienceBundle DigitalExperience" is incorrect — always use --metadata DigitalExperienceBundle DigitalExperience.

Validate:

sf project deploy validate --metadata DigitalExperienceBundle DigitalExperience DigitalExperienceConfig Network CustomSite --target-org ${usernameOrAlias}

Deploy:

sf project deploy start --metadata DigitalExperienceBundle DigitalExperience DigitalExperienceConfig Network CustomSite --target-org ${usernameOrAlias}
