name	platform-custom-application-generate
description	Use this skill when users need to create or configure tab-based Salesforce Custom Applications with navigation, branding, and action overrides. Trigger when users mention custom apps, application metadata, app navigation, or organizing tabs into applications. Use when users want to create app containers for tabs and pages. Do NOT use when the goal is hosting a React UI bundle in the App Launcher — use experience-ui-bundle-custom-app-generate for that case.

Purpose

• Organize related functionality into focused applications
• Group tabs and components for specific user roles

• Use Standard navigation for general business applications or Console navigation for specialized service/support workflows requiring multi-tab workspaces
• Create professional, branded application identity with custom colors and branding
• Override standard actions with custom Lightning pages for enhanced user experience
• Enable profile-specific experiences through profile action overrides

Application Configuration

Navigation Type Selection (CRITICAL)

Decision Criteria for navType:

Choose "Standard" (DEFAULT) for:

• General business applications and most workflows
• Single-record focus or linear navigation patterns
• Standard tab-based navigation is sufficient

Choose "Console" ONLY when workflow requires:

• Managing multiple related records simultaneously in split-view
• Multi-tab workspace for handling complex, interconnected data
• Contextual information from multiple sources visible at once
• Examples: customer service operations, support desks, call centers

When in doubt: Default to "Standard" for most general business use cases

Navigation Settings

• isNavAutoTempTabsDisabled: Controls automatic temporary tab creation
• isNavPersonalizationDisabled: Controls user personalization features

Best Practices

• Always use Lightning UI: Set uiType to "Lightning" for modern apps

• Use clear, descriptive application names
• Group related functionality logically
• Consider different user roles and needs
• Test across different device types
• Ensure proper permissions and access control
• Provide meaningful descriptions for users
• Follow consistent naming conventions
• Always configure branding: Set headerColor to create professional application identity
• Use accessible brand colors: Ensure hex colors have sufficient contrast (WCAG AA compliant)
• Configure utility bars: Add useful quick-access tools for users
• Leverage action overrides: Customize page layouts for specific objects using FlexiPages from flexipage expert
• Use profile overrides: Provide role-specific experiences by referencing different flexipage expert generated pages per profile
