Container/Presentation Component

Use this skill to create a React component under src/components that follows the Container/Presentation pattern.

Refer to this skill's bundled references for detailed rules.

• references/component-architecture.md
• references/typescript-and-scss-rules.md

If the /react-container-presentation-component input is incomplete, ask questions first before creating files.

When To Use

• When the user runs /react-container-presentation-component
• When the user explicitly asks for a React component that follows the Container/Presentation pattern
• When the user wants help deciding or implementing ui vs features classification within the Container/Presentation pattern

Required Questions

If any of the following information is missing, ask the user using ask_user.

1. Component name
2. Type (ui or features)
3. Whether to replace existing components (only when creating ui)

Question requirements:

• Provide the type as options (ui, features)
• Require the component name to be in PascalCase
• For ui, ask whether direct usage of Mantine or other UI libraries in existing features should be replaced with the new component

Procedure

1. Check existing components

• Check whether src/components/ui/<ComponentName> or src/components/features/<ComponentName> already exists.
• If it exists, do not overwrite; confirm the preferred approach with the user.

1. Decide target directory

• ui: src/components/ui/<ComponentName>
• features: src/components/features/<ComponentName>

1. Re-check classification (only when ui is specified)

• Even when ui is specified, before creating files, review Reclassification Rule in references/component-architecture.md.
• If the implementation includes state management, side effects, async processing, context/store updates, or business logic, treat it as features.
• If the result is closer to features, do not proceed as ui; use ask_user and confirm one of the following before continuing.
• Create as features
• Keep ui and move state/logic to parent or features

1. Create required files

• ui: index.tsx, index.module.scss, index.stories.tsx
• features: index.tsx, use<ComponentName>.tsx, presentation.tsx, types.ts, presentation.module.scss, presentation.stories.tsx

1. Replace existing usages (only when creating ui)

• Only when the user approves, replace equivalent direct implementations using Mantine or other UI libraries in existing features with the new ui component.

1. Validate

• Run build and lint commands, and ensure both pass; if issues are introduced by newly added or updated files, fix them.
• Follow Storybook Minimum in references/component-architecture.md for story state decisions.
• Ask the user via ask_user whether to run a Storybook check (for example: "Run" / "Skip for now").
• Run npm run storybook only if the user selects "Run".
• If the user selects "Skip for now", explicitly mention in the final report that Storybook execution was skipped.

Output Contract

• Report the list of files created.
• If replacements were performed, report the list of changed files and replacement details.
• Provide one usage example of the created component.
• Report whether Storybook verification was executed (run/skip), and if run, include the command used.
• Explain why the component was classified as ui or features.
• Summarize where state, side effects, and rendering responsibilities were placed.
• Confirm whether there were any dependency direction violations.
• Clearly state any unresolved items.
