mockgen-tailwind

Generate HTML mockup screens from PRD.md files for UI/UX human designer review. Creates a Node.js + Alpine.js + HTMX mockup server with admin dashboard layout (left sidebar navigation, header with logo/notifications/locale/user menu, footer with copyright/version) served as partials, organized by user role in a mockup/ folder. Input: application name (mandatory), version (mandatory), module (optional). Output: mockup/ folder in the application's context folder containing MOCKUP.html index page, server.js, package.json, partials/, and role-specific content subfolders. Trigger on keywords: "generate mockup", "generate mockups", "create mockup screens", "HTML mockup", "UI mockup from user stories", "mockup from PRD.md", "generate screens", "create UI screens". Accepts application name and version as input (e.g., `/mockgen-tailwind hub_middleware v1.0.3`). Optionally accepts a module name to limit generation to screens for that module only (e.g., `/mockgen-tailwind hub_middleware v1.0.3 module:Location Information`). When module is specified, only content files for that module are generated/updated; partials, sidebars, server files, and other module screens are left untouched. Automatically excludes strikethrough (deprecated/removed) items.

Mockgen HTML

Generate a Node.js + HTMX + Alpine.js mockup server from PRD.md for UI/UX designer review. Header, footer, and sidebar are served as partials. Content pages are HTMX fragments swapped into a shell layout. All image/PDF links open in new tabs.

Input

This skill uses standardized input resolution. Provide:

ArgumentRequiredExampleDescription
<application>Yeshub_middlewareApplication name to locate the context folder
<version>Yesv1.0.3Version to scope processing (filter user stories <= this version)
module:<name>Nomodule:Location InformationLimit generation to a single module

Application Folder Resolution

The application name is matched against root-level application folders:

  1. Strip any leading <number>_ prefix from folder names (e.g., 1_hub_middlewarehub_middleware)
  2. Match case-insensitively against the provided application name
  3. Accept snake_case, kebab-case, or title-case input (all match the same folder)
  4. If no match found, list available applications and stop

Auto-Resolved Paths

FileResolved Path
PRD.md<app_folder>/context/PRD.md
Module Models<app_folder>/context/model/
Output (mockup)<app_folder>/context/mockup/

Example Invocations

  • /mockgen-tailwind hub_middleware v1.0.3 (all modules, up to v1.0.3)
  • /mockgen-tailwind hub_middleware v1.0.3 module:Location Information (one module, specific version)
  • /mockgen-tailwind "Hub Middleware" v1.0.3 module:Employer (title-case app name)

Version and Module Filtering

  • Only include user stories, NFRs, constraints, and references from sections whose version tag is less than or equal to the target version
  • If a module is provided (e.g., module:Location Information), only generate/update screens for that specific module. All other modules are skipped. Common screens (home, profile, account, notifications), partials (shell, header, footer, sidebars), and server files are NOT regenerated when a module filter is active — only the module's own content fragments are written (and MOCKUP.html is updated for only that module's cards).
  • If no module is provided, process all modules (default behavior)

Argument parsing: The module: prefix is the canonical form. Also accept:

  • module:"Location Information" (quoted, with space)
  • module:location_information (snake_case — convert to title-case for matching)
  • Natural language: for Location Information module, only Location Information

Version Gate

Before starting any work, resolve the application folder first (see Input Resolution below), then check CHANGELOG.md in the application folder (<app_folder>/CHANGELOG.md):

  1. If <app_folder>/CHANGELOG.md does not exist, skip this check (first-ever execution for this application).
  2. If <app_folder>/CHANGELOG.md exists, scan all ## vX.Y.Z headings and determine the highest version using semantic versioning comparison.
  3. Compare the requested version against the highest version:
    • If requested version >= highest version: proceed normally.
    • If requested version < highest version: STOP immediately. Print: "Version {requested} is lower than the current application version {highest} recorded in <app_folder>/CHANGELOG.md. Execution rejected." Do NOT proceed with any work.

Workflow

Step 1: Parse PRD.md

Read the auto-resolved PRD.md file and extract:

  1. Application name: Derive from the parent folder name containing PRD.md. Strip leading number and underscore prefix, then title-case. Example: 1_hub_middleware -> "Hub Middleware"

  2. Application initials: First letter of each word, uppercase. Example: 1_hub_middleware -> "HM"

  3. Modules: Each ## Module Name section under a # Module Category heading. Record the module name and its description (the line after the heading).

  4. User stories per module: Lines matching - [USxx#####] As a {Role} user, I want to... Extract: tag, role, action summary.

  5. Unique roles: Collect all distinct roles from user stories. Example: "Hub Administrator", "Hub Operation Support"

  6. Target version (from input argument): If a version was provided, record it for filtering in the next sub-step.

1a: Version Filtering and Strikethrough Exclusion (MANDATORY)

PRD.md is a version-controlled document. Each section (User Story, Non Functional Requirement, Constraint, Reference) has a version tag in square brackets, e.g., [v1.0.1]. Items may also be marked with strikethrough (~~) to indicate they are deprecated/removed.

Strikethrough exclusion (always applied, regardless of version parameter):

  • Any line wrapped in ~~strikethrough~~ markup MUST be excluded from processing
  • This includes user stories, NFRs, constraints, and references
  • Example: ~~[USHM00006] As a Hub Administrator user, I want to...~~SKIP
  • Partially strikethrough lines (where only part is struck) should still be excluded if the tag identifier is within the strikethrough

Version filtering (applied only when a target version is provided):

  • Each section under a module has one or more version tags like [v1.0.0] or [v1.0.1]
  • Items listed under a version tag belong to that version
  • When a target version is specified (e.g., v1.0.1):
    • Include items from sections whose version tag is <= target version
    • Exclude items from sections whose version tag is > target version
  • Version comparison uses semantic versioning: compare major, then minor, then patch
  • When no target version is specified, include all items from all versions (but still exclude strikethrough items)

Version tracking per section: Record which version tag each item belongs to, as this will be used for traceability in the generated screens.

Example parsing of a section with multiple versions:

### User Story
[v1.0.0]
- ~~[USHM00006] As a Hub Administrator user, I want to manage...~~
- [USHM00009] As a Hub Administrator user, I want to map...
[v1.0.1]
- [USHM00012] As a Hub Administrator user, I want to manage the list...

With target version v1.0.0:

  • USHM00006 → EXCLUDED (strikethrough)
  • USHM00009 → INCLUDED (v1.0.0 <= v1.0.0, not strikethrough)
  • USHM00012 → EXCLUDED (v1.0.1 > v1.0.0)

With target version v1.0.1 (or no version specified):

  • USHM00006 → EXCLUDED (strikethrough)
  • USHM00009 → INCLUDED
  • USHM00012 → INCLUDED

1c: Module Filtering (applied only when a module argument is provided)

When a module argument is present, apply module filtering after version filtering:

  1. Match the specified module against the list of parsed modules (case-insensitive, ignoring leading/trailing whitespace). Also accept snake_case input by converting it to title-case for comparison (e.g., location_information → match "Location Information").
  2. Record the matched module name for use in Step 3 and beyond.
  3. If no module matches, stop and report the available module names to the user before proceeding.
  4. Module filter scope: the filter only affects content fragment generation (Step 6e). All other steps complete normally (parsing, design system, planning) but output is restricted to the filtered module's screens.

Module-filtered generation mode differs from full generation in these ways:

AspectFull GenerationModule-Filtered
Common screens (home, profile, account, notifications)Generate for every roleSKIP — already exist
Partials (shell, header, footer)GenerateSKIP — already exist
Sidebar per roleGenerateSKIP — already exist
server.js + package.jsonGenerateSKIP — already exist
Module content files (target module)GenerateGenerate / overwrite
Module content files (other modules)GenerateSKIP — leave untouched
MOCKUP.htmlGenerate full fileUpdate only the target module's cards
footer.html version stringUpdateUpdate (version may have changed)

MOCKUP.html partial update (module-filtered mode):

  • Read the existing MOCKUP.html
  • Locate the screen cards section for the target module (search by module name heading or existing card tags)
  • Replace only those cards with freshly generated ones reflecting the new screens
  • Update the total screen count per role (add net new screens)
  • Update the version badge if it changed
  • Update the "N new screens added in vX.Y.Z" banner text
  • Leave all other role sections and cards unchanged

Step 1b: Discover and Load Module Models

After parsing PRD.md, look for module models at the auto-resolved model path: <app_folder>/context/model/

For each module extracted in Step 1:

  1. Convert the module name to kebab-case to derive the model folder name:

    • Lowercase the module name and replace spaces with hyphens
    • Examples: "Location Information" → location-information, "Industrial Classification" → industrial-classification, "Employer" → employer
  2. Check for {model_dir}/{kebab-module}/model.md

  3. If the file exists, parse it and extract the following sections:

    • Section 2 – Collection Catalog: collection names and types (Root Collection, Audit Collection, etc.)
    • Section 5 – Field Detail per Collection: for each collection — field name, type, required, nullable, constraints/notes
    • Section 6 – Embedded Document Definitions: embedded type name and its sub-fields
    • Section 7 – Enum Definitions: enum name and all allowed values with descriptions
    • Section 9 – Index Recommendations: indexed fields (used to identify search/filter parameters)
  4. Store this as the module model for the module, keyed by module name

Field classification (used during content generation in Step 6e):

CategoryDefinitionUsage
System fields_id, _audit, _version, deleted, deletedAt, deletedByExclude from user-facing forms
Audit-only fieldsFields whose Source is CONVENTION and type is AuditShow in detail views only
Required form fieldsRequired: Yes AND not a system fieldMandatory inputs in create/edit forms
Optional form fieldsRequired: No AND not a system fieldOptional inputs in create/edit forms
Read-only after creationFields marked as unique identity keys (e.g., companyRegistrationNumber)Show in edit forms as readonly
Search/filter fieldsFields referenced in Index RecommendationsRender as filter controls in list screens
Enum fieldsType matches an entry in Section 7 Enum DefinitionsRender as <select> dropdowns
Embedded object fieldsType is a custom embedded document type (not a primitive)Render as <fieldset> sub-group
Embedded array fieldsType ends in [] (e.g., PersonInCharge[])Render as repeatable row with Add/Remove

Fallback: If no model.md exists for a module, infer fields from user story text (original behavior).


Step 2: Load Design System

Load the design system using a two-tier resolution strategy:

2a: PRD.md Design System Reference (Primary Source)

Check if PRD.md contains a # Design System section. If it does:

  1. Extract the referenced file path (e.g., from [DESIGN_SYSTEM.md](reference/DESIGN_SYSTEM.md))
  2. Resolve the path relative to PRD.md's location
  3. If the referenced file exists, read it and extract:
    • Color palettes (primary, secondary, accent, neutral — hex values)
    • Typography (font families, font sizes, weight scale)
    • Spacing scale (if overriding Tailwind defaults)
    • Component patterns (button styles, card styles, form input styles, table styles, badge/chip styles, modal patterns)
    • Layout grid rules
  4. Apply extracted tokens to the Tailwind CDN <script> config block in shell.html (custom colors, fonts), all generated partials (consistent color classes), and component rendering

2b: Context Design Folder (Fallback)

If PRD.md does not have a # Design System section, or the referenced file does not exist, fall back to the application's <app_folder>/context/design/ folder. This folder contains pre-defined design tokens and Tailwind component guidelines maintained externally by the UI/UX team.

Read all files in {app_name}/context/design/ (where {app_name} is the resolved application folder name from Step 1). Apply the design tokens and guidelines found there to all generated mockup screens.

Expected files (any or all may be present):

  • design-system.md — Colors, typography, spacing, and visual style definitions
  • components.md — Reusable component patterns and Tailwind class conventions
  • guidelines.md — Layout rules, accessibility standards, and stack-specific guidelines

2c: Default Fallback

If neither the PRD reference nor the {app_name}/context/design/ folder provides design tokens, use sensible defaults: a neutral color palette, Inter/system font stack, and standard Tailwind utility classes for spacing and layout.

2d: Process Flow Status States

If PRD.md contains a # High Level Process Flow section, scan it for entity status lifecycle descriptions (e.g., "Received → Validated → Enriched → Active"). For each status lifecycle found:

  • Ensure list screens for the corresponding module include a status column with colored badges for each state
  • Use design system color tokens for badge colors (e.g., success color for active/completed states, warning for pending, danger for failed/rejected)

Step 3: Plan Screen Files

For each role, determine ALL screens to generate. Every clickable link, tab, or action in any generated screen MUST have a corresponding content fragment file. No link may point to # or be a dead end.

Module filter applied here: If a module argument was provided (Step 1c), plan only the screens for that module across all roles. Skip common screens (home, profile, account, notifications) and skip all other modules entirely. The screen plan table should list only the filtered module's screens.

3a: Core Screens (content fragments)

  1. home.html: Default home/dashboard page with welcome message and summary widgets
  2. profile.html: User profile page (linked from header user dropdown)
  3. account.html: Account settings page (linked from header user dropdown)
  4. notifications.html: Notifications page (linked from header notification bell)
  5. One screen per module that has user stories for this role

3b: Sub-Screens (Detail / Edit / Create)

For each module screen, analyze the user stories and identify sub-screens needed:

User Story PatternSub-Screen Required
"view details of X"{module}_detail.html - Detail view for a single record
"add/create/register X"{module}_create.html - Create/add form
"edit/update/modify X"{module}_edit.html - Edit form (pre-filled)
"view history/audit of X"{module}_history.html - History/audit log view
"view associated X of Y"{module}_{sub}_list.html - Associated records list

3f: Report Layout Screens (conditional — if PRD.md contains report-related content)

Scan PRD.md for report-related content:

  • NFRs mentioning "report", "Report interface", "generate report", "report generation"
  • User stories describing generating/downloading PDF, Excel, or CSV reports
  • A "Report" module or report-related NFRs defining specific report types

If report requirements are found, generate HTML report layout mockups for each identified report. These layouts serve as draft previews for human designers/stakeholders to verify the report structure before the AI coding agent implements the actual report generation code (JasperReports JRDesign API for Java, Puppeteer for Laravel/React).

For each identified report, create a standalone HTML file in a reports/ subfolder:

Report SourceFile Generated
NFR describes "Staff Allocation Summary report"reports/staff_allocation_summary.html
User story: "generate Job Demand report by country"reports/job_demand_by_country.html
Report module NFR: "Monthly Activity Report"reports/monthly_activity_report.html

Report layout file conventions:

  • Each report layout is a standalone self-contained HTML document (not a content fragment) with its own <html>, <head>, <body> tags and Tailwind CDN <script> in the head
  • Layout simulates a print-ready A4 page with appropriate margins and sizing:
    <body class="bg-gray-100">
      <div class="mx-auto bg-white shadow" style="width: 210mm; min-height: 297mm; padding: 15mm;">
        <!-- Report content -->
      </div>
    </body>
    
  • Report header: Report title (centered, bold), generation date, filter parameters used
  • Report body: Data table or summary layout using actual fields from the module model (if model/{module}/model.md exists, use its field definitions for column headers)
  • Report footer: Page indicator text ("Page 1 of 1"), generation timestamp
  • Use sample data rows (5-10 rows) with realistic placeholder values matching model constraints
  • Apply the design system colors from Step 2 for header background, borders, and accents
  • For landscape reports (wide tables with many columns), use style="width: 297mm; min-height: 210mm;"

Report parameter section: Above the report data, include a gray-shaded "Parameters" box showing the filter criteria used to generate the report (e.g., Date Range: 2025-01-01 to 2025-12-31, Department: All, Status: Active).

Add to MOCKUP.html: Include a "Reports" section at the bottom of each role's screen cards (after all module cards) listing the report layout links. Report links open in new tabs pointing directly to the standalone HTML files (no server route needed — static files).

Add to sidebar: If reports are present, add a "Reports" navigation group in each role's sidebar with links opening report layouts in new tabs.

3c: Tabbed Screens

If a module screen contains tabs (e.g., a detail page with Overview, Documents, History tabs), each tab MUST be a separate content fragment file unless the tab content is trivially small. Use the naming convention: {module}_tab_{tab_name}.html

Example: employer_tab_overview.html, employer_tab_documents.html, employer_tab_history.html

3d: Screen File Naming Convention

Convert names to snake_case, no .html extension in HTMX route references. Example: "Location Information" -> location_information

3e: Build Screen Plan

Build a complete screen plan. Every entry must map to a generated file:

RoleFolder NameScreen FileSourceDescription
Hub Administratorhub_administratorhomeCommonDashboard home
Hub Administratorhub_administratorprofileCommonUser profile
Hub Administratorhub_administratoraccountCommonAccount settings
Hub Administratorhub_administratornotificationsCommonNotifications list
Hub Administratorhub_administratorlocation_informationModuleUSHM00006, USHM00009

Hub Operation Supporthub_operation_supporthomeCommonDashboard home

Hub Operation Supporthub_operation_supportemployer_detailSub-screenView employer details
Hub Operation Supporthub_operation_supportemployer_createSub-screenRegister new employer

Step 4: Create Output Folder Structure

Module filter: When a module argument is active, skip this step entirely — the folder structure already exists from a previous full generation. Only content files for the target module will be written in Step 6e.

Create the mockup folder at the auto-resolved mockup output path (full generation only):

<app_folder>/context/
  mockup/
    .gitignore                       # Git ignore for node_modules, etc.
    server.js                        # Express server
    package.json                     # Node.js dependencies
    MOCKUP.html                      # Landing/index page (static)
    partials/
      shell.html                     # Page shell (assembled server-side)
      header.html                    # Top header with Alpine.js dropdowns
      footer.html                    # Footer partial
      sidebar-{role_snake_case}.html # One sidebar per role with HTMX nav
    {role_snake_case}/
      content/
        home.html                    # Content fragment (no layout wrapper)
        profile.html
        account.html
        notifications.html
        {module_snake_case}.html
        {module_snake_case}_detail.html
        {module_snake_case}_create.html
        {module_snake_case}_edit.html
        ...

Step 4b: Generate Server Files

Module filter: When a module argument is active, skip this step entirely.

Generate .gitignore, server.js, and package.json using the templates from references/admin-layout-template.md.

.gitignore

Create a .gitignore file in the mockup folder with the following content:

node_modules/
package-lock.json
.DS_Store
*.log

Key behaviours of server.js:

  • GET / → serves MOCKUP.html (static landing page)
  • GET /:role → redirects to /:role/home
  • GET /:role/:page → assembles full HTML from shell + header + sidebar + content + footer
  • GET /api/content/:role/:page → returns content fragment only (for HTMX in-page swaps)
  • Injects {{ROLE}} into header and sidebar partials before responding (so HTMX links in dropdowns and sidebar reference the correct role)

Step 5: Generate MOCKUP.html Index

Module filter: When a module argument is active, do NOT regenerate the full MOCKUP.html. Instead, apply a partial update as described in Step 1c: update only the target module's screen cards, the version badge, and the per-role screen count. Leave all other content unchanged.

Create the index page using the template in references/mockup-index-template.md.

MOCKUP.html is a standalone static HTML file (no server required to open it) that shows:

  • Server startup banner with instructions (npm install && npm start)
  • Application name and description
  • Target version used for generation
  • Number of excluded items for transparency
  • For each role: role name, list of screen cards with links
  • ALL screen links use target="_blank" rel="noopener noreferrer" pointing to http://localhost:3000/{role}/{page} so they open in new tabs via the running server
  • A "Open Role Dashboard" quick-launch link per role section

Step 6: Generate Partials and Content Fragments

Use templates from references/admin-layout-template.md.

Apply the design system from Step 2 (colors, typography, spacing) to all templates.

Module filter: When a module argument is active, skip steps 6a–6d (shell, header, footer, sidebars). Proceed directly to 6e for the target module's content fragments only. Also update partials/footer.html if the version string changed (the footer version badge must always reflect the current target version).

6a: Generate partials/shell.html

Single shared shell file. The server replaces {{HEADER}}, {{SIDEBAR}}, {{CONTENT}}, and {{FOOTER}} at request time. Includes HTMX, Alpine.js, and Tailwind CDN.

6b: Generate partials/header.html

One header partial (or one per role if HTMX links differ per role). Contains:

  • Logo + App Name (left)
  • Notification bell with Alpine.js dropdown (x-data, @click, @click.outside)
  • Globe/locale selector with Alpine.js dropdown
  • Dark mode toggle button (dispatches to parent appShell() Alpine context)
  • User avatar with Alpine.js dropdown (Profile, Account, Logout)
  • All notification/profile/account navigation links use HTMX (hx-get, hx-target="#content-area")

6c: Generate partials/footer.html

Simple footer with copyright year and version string.

6d: Generate partials/sidebar-{role}.html (one per role)

Each sidebar contains HTMX-powered navigation links:

<a href="/{{ROLE}}/{{PAGE}}"
   hx-get="/api/content/{{ROLE}}/{{PAGE}}"
   hx-target="#content-area"
   hx-swap="innerHTML"
   hx-push-url="/{{ROLE}}/{{PAGE}}"
   ...>

Alpine.js :class binding highlights the active menu item based on window.location.pathname.

6e: Generate content fragments ({role}/content/{page}.html)

Each content fragment contains only the page content — no <html>, <head>, <body>, no Tailwind config, no CDN scripts. Structure:

[breadcrumb bar div]
[main content div with padding]

All navigation links within content fragments use HTMX (same pattern as sidebar).

Breadcrumbs: Home link uses HTMX; module link uses HTMX; current page is plain text.

Admin Layout: Screen Content Generation

For each module screen, analyze the user stories and generate appropriate UI mockup elements:

User Story PatternUI Element
"search for X based on parameters"Search form with filter fields + results table
"view details of X"Detail view with labeled fields in card/panel layout
"manage X" / "configure X"CRUD table with Add/Edit/Delete actions
"view history/changes"Timeline or audit log table with timestamps
"map X to Y"Two-panel mapping interface or matrix table
"activate/deactivate X"Alpine.js toggle switches in table rows or config panel
"view associated X"Related records table or linked cards section

Model-Driven Field Usage (MANDATORY when model file exists)

When a module model was loaded in Step 1b, use its actual field definitions — not generic placeholders — to populate every screen. Generic field names like "Field 1" or "Description" are not acceptable when a model is available.

Field type → HTML input mapping:

Model TypeForm InputNotes
String<input type="text">Use maxlength if constraints specify length
Number<input type="number">
BooleanAlpine.js toggle (x-data, @click)
ISODate<input type="date"> or <input type="datetime-local">
ObjectId (reference)<input type="text" readonly> or lookup widgetDisplay as read-only ID reference
Enum (Section 7 match)<select> with all enum values as <option>Show enum value descriptions as option text
Embedded Object<fieldset> grouping sub-fieldsLabel the fieldset with the embedded type name
Embedded Array ([])Repeatable section with "+ Add" / "Remove" buttonsShow one pre-filled example row

List / Search screens ({module}.html):

  • Filter form: render filter inputs only for fields that appear in Index Recommendations (Section 9). Use the correct input type per the mapping above. Enum-indexed fields use <select>. Date-indexed fields use date range pickers.
  • Results table: choose 5–7 of the most identifying non-system fields as columns. For embedded objects, show them as a single column (e.g., "Company Name" rather than expanding all sub-fields). Null/optional fields can be shown with a dash () in sample data.
  • Table row actions: View → {module}_detail, Edit → {module}_edit, Delete → Alpine.js confirm
  • Pagination (MANDATORY): Every results table MUST include a pagination bar directly below the table. Requirements:
    • Default page size: 10 items per page
    • Show "Showing X–Y of Z results" summary text on the left
    • Show page size selector (<select>) with options 10, 25, 50 on the right (default 10)
    • Show Previous / Next buttons and page number buttons in the centre
    • Page number buttons: show first page, last page, current page ± 1, with ... ellipsis for gaps
    • Use Alpine.js x-data="{ currentPage: 1, pageSize: 10, totalItems: 47 }" (sample total) to drive display state
    • Page buttons use HTMX hx-get linking to the same route (self-referential) — acceptable per Link Integrity Rule 6
    • Previous/Next buttons are disabled (visual only with opacity-50 cursor-not-allowed) when at first/last page
    • Use sample data: populate exactly 10 visible rows in the table (matching the default page size)

Detail screens ({module}_detail.html):

  • Show ALL non-system fields, grouped logically:
    • Basic fields: flat primitive fields in a 2-column grid card
    • Embedded objects (e.g., address, contact): each in its own labelled sub-card
    • Embedded arrays (e.g., personsInCharge): rendered as a sub-table with a row per item
    • Enum fields: display value wrapped in a colored badge/chip
    • ISODate fields: formatted as DD MMM YYYY HH:mm in sample data
    • Boolean fields: show as a green/red badge ("Active" / "Inactive")
  • Include Edit, Delete (Alpine.js confirm), and Back to List action buttons

Create screens ({module}_create.html):

  • Include ALL Required: Yes non-system fields as mandatory inputs (mark with *)
  • Include Required: No fields as optional inputs where they make sense for initial creation
  • Group embedded objects as <fieldset> sections with a legend
  • For embedded arrays: show one empty repeatable row with an "+ Add" button
  • Submit and Cancel buttons; Cancel navigates back to {module} list screen

Edit screens ({module}_edit.html):

  • Same structure as create screen but with sample data pre-filled in all inputs
  • Fields that serve as unique identity keys (e.g., companyRegistrationNumber) must be rendered as <input readonly> with a tooltip explaining they cannot be changed
  • Save and Cancel buttons

History / Audit screens ({module}_history.html):

  • Use fields from the audit/history collection (the non-root collection in the Collection Catalog):
    • changeType → colored badge using enum values from Section 7
    • fieldChanged → code-styled text (<code>)
    • previousValue / newValue → inline diff or truncated JSON display
    • changedAt → formatted timestamp
    • changedBy → plain text (e.g., "SYSTEM" or username)
  • Render as a chronological table, newest first
  • Pagination (MANDATORY): Include pagination bar below the history table. Default 10 items per page. Same Alpine.js + HTMX pattern as list screens (see above).

Sample data alignment: Placeholder values in screens must be consistent with field constraints:

  • countryCode → use actual allowed values (e.g., "MYS", "BHR", "MDV") per CONSHM constraints if present in model notes
  • Enum fields → use one of the defined enum values (not arbitrary strings)
  • companyRegistrationNumber → e.g., "201901012345 (1234567-X)"
  • ISODate fields → use realistic ISO dates (e.g., "2025-08-15T10:30:00Z")

Link Integrity Rules (CRITICAL)

Every clickable element MUST navigate to a real route. No href="#" allowed anywhere.

  1. Table row actions (View, Edit, Delete):

    • "View" / "Details" → HTMX link to /{role}/{module}_detail
    • "Edit" → HTMX link to /{role}/{module}_edit
    • "Delete" → Alpine.js inline confirm dialog (href="javascript:void(0)")
    • "Add New" / "Create" → HTMX link to /{role}/{module}_create
  2. Tabs within a screen:

    • Each tab MUST HTMX-link to its corresponding content file
    • The current tab is visually active; other tabs link to their respective content pages
  3. Header links:

    • Notification bell icon → HTMX nav to notifications
    • Notification dropdown "View all notifications" → HTMX nav to notifications
    • Locale dropdown options → javascript:void(0) (static language switcher mockup)
    • Night mode toggle → Alpine.js @click="toggleDark()" (no href)
    • Profile dropdown → HTMX nav to profile
    • Account dropdown → HTMX nav to account
    • Logout → href="/" (returns to landing page)
  4. Sidebar links: HTMX links to correct module screen routes (already enforced)

  5. Breadcrumb links: HTMX links

    • Home → /{role}/home
    • Module → /{role}/{module}
    • Detail / current → plain text, no link
  6. Pagination links: HTMX hx-get links to the same route (self-referential) are acceptable. Pagination is MANDATORY on every list — page buttons must use hx-get with the same route, not href="#"

  7. Back / Cancel buttons: HTMX link to the parent screen

  8. Images (inline previews, thumbnails, etc.):

    • Must open the full image in a new tab via <a href="..." target="_blank" rel="noopener noreferrer">
    • Use placeholder image URLs like https://placehold.co/800x600
  9. PDFs and documents (download/view links):

    • Must open in a new tab via <a href="..." target="_blank" rel="noopener noreferrer">
    • Never render PDFs inline within the mockup

Content guidelines:

  • Use placeholder/sample data that reflects the module context
  • Include appropriate form fields based on NFRs and constraints
  • Show the user story tags with their version as HTML comments for traceability (e.g., <!-- USHM00012 [v1.0.1] -->)
  • All interactive elements use Alpine.js (x-data, x-show, @click, :class)
  • Use Tailwind utility classes for all styling
  • Use inline Heroicons SVG (no external icon dependencies)

Common Screens Content

profile.html: User profile page showing:

  • User avatar, full name, email, role badge
  • Personal information form (read-only display): Name, Email, Phone, Department
  • "Edit Profile" button (HTMX links to self since it's a mockup)

account.html: Account settings page showing:

  • Change Password section (current password, new password, confirm password fields)
  • Notification Preferences (Alpine.js email/SMS toggles)
  • Language/Locale selector (Alpine.js)
  • Session Management (active sessions table)

notifications.html: Notifications list page showing:

  • Alpine.js filter tabs: All, Unread, Read
  • List of notification cards with: icon, title, message preview, timestamp, read/unread dot
  • Mark all as read button
  • Pagination (MANDATORY): Pagination bar below the notification list, default 10 items per page. Same Alpine.js + HTMX pattern as list screens.

Sub-Screen Content

{module}_detail.html: Record detail page showing:

  • Page title with record identifier
  • Back button (HTMX link to {module})
  • Detail cards/panels with all relevant fields from user stories
  • Action buttons: Edit (HTMX to {module}_edit), Delete (Alpine.js confirm), Back to List
  • Related data sections if applicable
  • If the entity has sub-entities, show them in HTMX-linked tabs or sections

{module}_create.html: Create/add form page showing:

  • Page title: "Add New {Entity}"
  • Breadcrumb: Home > {Module} > Add New
  • Form with all required fields derived from user stories
  • Submit and Cancel buttons (Cancel: HTMX link to {module})

{module}_edit.html: Edit form page showing:

  • Page title: "Edit {Entity}"
  • Breadcrumb: Home > {Module} > Edit
  • Pre-filled form with sample data
  • Save and Cancel buttons (Cancel: HTMX link to {module}_detail or {module})

Step 7: Output Summary

After generation, print a summary:

Mockup Generation Complete
===========================
Application: {App Name} ({Initials})
Target Version: {version or "latest (all versions)"}
Module Filter: {module name or "all modules"}
Output: {path}/mockup/

Filtering Summary:
- User stories included: {count}
- User stories excluded (strikethrough): {count}
- User stories excluded (version filter): {count}
- User stories excluded (module filter): {count}
- NFRs/Constraints included: {count}
- NFRs/Constraints excluded: {count}

| Role                  | Screens | Content Folder                    |
|-----------------------|---------|-----------------------------------|
| Hub Administrator     | 8       | hub_administrator/content/        |
| Hub Operation Support | 6       | hub_operation_support/content/    |

Files generated:
- .gitignore
- server.js + package.json
- partials/shell.html, header.html, footer.html
- partials/sidebar-hub_administrator.html
- partials/sidebar-hub_operation_support.html
- {N} content fragment files

Total: {N} files

Quick Start
===========
1. cd {mockup folder path}
2. npm install
3. npm start
4. Open http://localhost:3000 in your browser
   (or open MOCKUP.html directly for the index)

Step 7b: Link Integrity Validation (MANDATORY)

Before finalizing output, perform a link integrity check across ALL generated files:

  1. Scan every generated file for all href, hx-get, and hx-push-url attribute values
  2. Build a link registry: map every route reference to the file that should exist
  3. Verify each HTMX route resolves to an existing content fragment:
    • hx-get="/api/content/{role}/{page}" → verify {role}/content/{page}.html exists
    • href="javascript:void(0)" → acceptable for delete confirm, locale switcher
    • href="/" → acceptable for logout
    • target="_blank" links → acceptable for images, PDFs, external resources
    • href="#"NOT ALLOWED — dead link, must be fixed
  4. For any missing target file, either:
    • Generate the missing content fragment, OR
    • Update the link to point to an existing route
  5. Report any fixes made during validation in the output summary

If any href="#" is found in the final output (excluding anchor-only usage), the generation is incomplete.

Changelog Append

After all mockup files are successfully generated, append an entry to CHANGELOG.md in the application folder (<app_folder>/CHANGELOG.md):

  1. Read <app_folder>/CHANGELOG.md. If it does not exist, create it with:
    # Changelog
    
    - This file tracks all skill executions by version for this application.
    - The highest version recorded here is the current application version.
    - Skills MUST NOT execute for a version lower than the highest version in this file.
    
    ---
    
  2. Search for a ## {version} heading matching the current version.
  3. If the section exists: append a new row to its table.
  4. If the section does not exist: insert a new section after the --- below the context header and before any existing ## vX.Y.Z section (newest-first ordering), with a new table header and the first row.
  5. Row format: | {YYYY-MM-DD} | {application_name} | mockgen-tailwind | {module or "All"} | Generated HTML mockup screens |
  6. Never modify or delete existing rows.

Important Rules

  • Module filter is additive, not destructive: When module: is specified, only the named module's content files are written/overwritten. All other files (partials, other module content, server.js) remain untouched. If the target module does not exist in PRD.md, stop and report available module names before doing any file writes.
  • Version + module are independent axes: Both may be combined freely. module:Employer v1.0.2 means "generate Employer module screens as they exist at v1.0.2". Version filtering and module filtering each apply independently; a story must satisfy BOTH to be included.
  • ZERO dead links: Every href and hx-get in every file must resolve. No href="#"
  • Pagination on every list (MANDATORY): Every screen that renders a table or card list of records MUST include a pagination bar below it. Default page size is 10 items per page. Applies to: module list screens, history/audit screens, notifications screen, and any embedded sub-tables within detail screens that may grow unbounded. Use Alpine.js x-data for page state and HTMX hx-get (self-referential) for page navigation. Omitting pagination from any list is a generation error.
  • Partials for layout: Header, footer, and sidebar are partial files, NOT duplicated inline
  • Content fragments only: Role screen files contain only page content — no <html>/<head>/<body>
  • HTMX navigation: All in-app navigation uses HTMX (hx-get, hx-target, hx-push-url)
  • Alpine.js for interactivity: Dropdowns, toggles, confirm dialogs use Alpine.js
  • Images open in new tab: Any <img> link or image view action uses target="_blank"
  • PDFs open in new tab: Any PDF/document view link uses target="_blank" rel="noopener noreferrer"
  • MOCKUP.html links open in new tab: All screen card links in the index use target="_blank"
  • No external image dependencies; use https://placehold.co/ for placeholder images
  • Use inline SVG Heroicons only; no icon CDN dependencies
  • Sidebar navigation must link between screens within the same role using HTMX
  • Header navigation (notification, profile, account) links use HTMX
  • Table action buttons (View, Edit, Add) use HTMX navigation
  • Tabs within screens each link to a corresponding content fragment via HTMX
  • Back/Cancel buttons use HTMX to navigate to the parent list or detail screen
  • Preserve traceability: include user story tags with version as HTML comments in each screen (e.g., <!-- USHM00012 [v1.0.1] -->)
  • Do not generate screens for modules that have no user stories for a given role
  • Common screens (home, profile, account, notifications) are generated for EVERY role
  • Use consistent color scheme from the design system across all partials and content fragments
  • The version displayed in footer should be the target version if specified, or the latest version found in PRD.md
  • Strikethrough items MUST always be excluded — lines wrapped in ~~ are deprecated/removed
  • Version filtering: When a target version is provided, only include items from sections with version tags <= target version
  • Model-driven screens: When a module model file exists at model/{kebab-module}/model.md, use the actual field definitions (field names, types, required/nullable, enums) for all form inputs, table columns, and detail panels. Generic placeholder field names are NOT acceptable when a model is available. See Step 1b and the "Model-Driven Field Usage" section.
  • Enum accuracy: Enum select options must use the exact values from the model's Enum Definitions (Section 7), not inferred strings
  • Constraint-aware sample data: Sample values must respect field constraints noted in the model (e.g., use MYS, BHR, MDV for countryCode fields constrained by CONSHM018)
  • Report layouts: When PRD.md contains report-related NFRs or user stories, generate standalone HTML report layout files in reports/ subfolder. These are self-contained A4 mockups (not content fragments) for stakeholder review of report structure before coding. Use actual module model fields for column headers and realistic sample data rows. See Step 3f for full report layout generation rules.
