sf-lwc: Lightning Web Components Development

Use this skill when the user needs Lightning Web Components : LWC bundles, wire patterns, Apex/GraphQL integration, SLDS 2 styling, accessibility, performance work, or Jest unit tests.

When This Skill Owns the Task

Use sf-lwc when the work involves:

• lwc/**/*.js, .html, .css, .js-meta.xml
• component scaffolding and bundle design
• wire service, Apex integration, GraphQL integration
• SLDS 2, dark mode, and accessibility work
• Jest unit tests for LWC

Delegate elsewhere when the user is:

• writing Apex controllers or business logic first → sf-apex
• building Flow XML rather than an LWC screen component → sf-flow
• deploying metadata → sf-deploy

Required Context to Gather First

Ask for or infer:

• component purpose and target surface
• data source: LDS, Apex, GraphQL, LMS, or external system via Apex
• whether the user needs tests
• whether the component must run in Flow, App Builder, Experience Cloud, or dashboard contexts
• accessibility and styling expectations

Recommended Workflow

1. Choose the right architecture

Use the PICKLES mindset:

• prototype
• integrate the right data source
• compose component boundaries
• define interaction model
• use platform libraries
• optimize execution
• enforce security

2. Choose the right data access pattern

3. Start from an asset when useful

Use provided assets for:

• basic component bundles
• datatables
• modal patterns
• Flow screen components
• GraphQL components
• LMS message channels
• Jest tests
• TypeScript-enabled components

4. Validate for frontend quality

Check:

• accessibility
• SLDS 2 / dark mode compliance
• event contracts
• performance / rerender safety
• Jest coverage when required

5. Hand off supporting backend or deploy work

Use:

• sf-apex for controllers / services
• sf-deploy for deployment
• sf-testing only for Apex-side test loops, not Jest

High-Signal Rules

• prefer platform base components over reinventing controls
• use @wire for reactive read-only use cases; imperative calls for explicit actions and DML paths
• do not introduce inaccessible custom UI
• avoid hardcoded colors; use SLDS 2-compatible styling hooks / variables
• avoid rerender loops in renderedCallback()
• keep component communication patterns explicit and minimal

Output Format

When finishing, report in this order:

1. Component(s) created or updated
2. Data access pattern chosen
3. Files changed
4. Accessibility / styling / testing notes
5. Next implementation or deploy step

Suggested shape:

LWC work: <summary>
Pattern: <wire / apex / graphql / lms / flow-screen>
Files: <paths>
Quality: <a11y, SLDS2, dark mode, Jest>
Next step: <deploy, add controller, or run tests>
