DynamoHome: Skill for Claude Code

UI Feature Workflow – DynamoHome

Use this workflow when implementing a new UI feature or modifying existing UI.

Steps

1. Identify scope

Determine which module(s) are affected and read the existing components before making changes:

Module	Location
Recent files	src/components/Recent/
Sample graphs	src/components/Samples/
Learning resources	src/components/Learning/
Sidebar navigation	src/components/Sidebar/
Shared / reused	src/components/Common/

2. Add localized strings first

Before writing any JSX with user-visible text:

1. Add the key to src/locales/en.json
2. Add the same key (English value as placeholder) to all 13 other locale files
3. Key format: module.element.descriptor (e.g. recent.filter.label.search)

See the localization skill for patterns and the full locale list.

3. Implement the UI change

• Functional component with explicit prop interface
• CSS Modules for styling (styles['class-name'])
• <FormattedMessage> or useIntl() for all user-visible text
• No new libraries

If adding a new component, create ComponentName.tsx + ComponentName.module.css together in the module folder.

interface MyFeatureProps {
  value: string;
  onChange: (v: string) => void;
}

export const MyFeature = ({ value, onChange }: MyFeatureProps) => {
  const intl = useIntl();
  return (
    <div className={styles['my-feature']}>
      <span><FormattedMessage id="module.myfeature.label" /></span>
      <input
        value={value}
        onChange={e => onChange(e.target.value)}
        placeholder={intl.formatMessage({ id: 'module.myfeature.placeholder' })}
      />
    </div>
  );
};

4. Update SettingsContext if the feature needs persistence

If the feature requires persisting a user preference (e.g. a new view mode or toggle):

• Add the new field to SettingsContext.tsx
• Update saveHomePageSettings() in src/functions/utility.ts
• Adding new fields to the settings JSON is safe; never rename or remove existing fields
