get_component_docs

Instructions

Implementation Reference

• src/index.ts:122-125 (schema)

  Zod schema for get_component_docs tool input validation: requires 'component' (string) and optionally 'section' (enum: usage, props, examples, accessibility).

  const GetComponentDocsSchema = z.object({
    component: z.string().describe("Component name to get documentation for"),
    section: z.enum(["usage", "props", "examples", "accessibility"]).optional(),
  });

• src/index.ts:323-336 (registration)

  Registration of the get_component_docs tool in the ListToolsRequestSchema handler on the MCP server.

  {
    name: "get_component_docs",
    description:
      "Get documentation, usage examples, and prop descriptions for a component",
    inputSchema: {
      type: "object",
      properties: {
        component: { type: "string", description: "Component name" },
        section: {
          type: "string",
          enum: ["usage", "props", "examples", "accessibility"],
        },
      },
      required: ["component"],

• src/index.ts:463-474 (handler)

  Handler case in CallToolRequestSchema: parses args with schema, calls documentationTools.getComponentDocs(), returns result as text content.

  case "get_component_docs": {
    const { component, section } = GetComponentDocsSchema.parse(args);
    const docs = documentationTools.getComponentDocs(component, section);
    return {
      content: [
        {
          type: "text",
          text: docs,
        },
      ],
    };
  }

• src/tools/documentationTools.ts:4-27 (helper)

  Core implementation: looks up component from registry and delegates to section-specific doc generators (getUsageDoc, getPropsDoc, getExamplesDoc, getAccessibilityDoc).

  getComponentDocs(componentName: string, section?: string): string {
    const component = componentRegistry.getComponent(componentName);
  
    if (!component) {
      return `Component "${componentName}" not found. Available components: ${Object.keys(
        componentRegistry.listComponents("all"),
      ).join(", ")}`;
    }
  
    if (!section || section === "usage") {
      return this.getUsageDoc(component);
    }
  
    switch (section) {
      case "props":
        return this.getPropsDoc(component);
      case "examples":
        return this.getExamplesDoc(component);
      case "accessibility":
        return this.getAccessibilityDoc(component);
      default:
        return this.getUsageDoc(component);
    }
  },

• src/tools/documentationTools.ts:1-343 (helper)

  Complete documentationTools module containing all helper methods for generating formatted documentation strings for components.

  import { componentRegistry } from "../components/registry.js";
  
  export const documentationTools = {
    getComponentDocs(componentName: string, section?: string): string {
      const component = componentRegistry.getComponent(componentName);
  
      if (!component) {
        return `Component "${componentName}" not found. Available components: ${Object.keys(
          componentRegistry.listComponents("all"),
        ).join(", ")}`;
      }
  
      if (!section || section === "usage") {
        return this.getUsageDoc(component);
      }
  
      switch (section) {
        case "props":
          return this.getPropsDoc(component);
        case "examples":
          return this.getExamplesDoc(component);
        case "accessibility":
          return this.getAccessibilityDoc(component);
        default:
          return this.getUsageDoc(component);

          Submit Form
        </${component.name}>
      </form>
    );
  }
  \`\`\`
  
  ### With Custom Theming
  \`\`\`jsx
  import { ThemeProvider, ${component.name} } from 'its-just-ui';
  
  const customTheme = {
    colors: {
      primary: '#007bff',
      secondary: '#6c757d'
    }
  };
  
  function ThemedExample() {
    return (
      <ThemeProvider theme={customTheme}>
        <${component.name} variant="primary">
          Custom Themed
        </${component.name}>
      </ThemeProvider>
    );
  }
  \`\`\``;
    },
  
    getAccessibilityDoc(component: any): string {
      return `# ${component.name} Accessibility
  
  ## Accessibility Features
  
  ${component.accessibility
    .map(
      (feature: string) => `### ${feature}
  - Fully implemented and tested
  - Complies with WCAG 2.1 Level AA standards`,
    )
    .join("\n\n")}
  
  ## ARIA Attributes
  
  The ${component.name} component includes the following ARIA attributes:
  
  - \`role\`: Appropriate ARIA role for the component
  - \`aria-label\`: Descriptive label for screen readers
  - \`aria-labelledby\`: Associates with label elements
  - \`aria-describedby\`: Associates with description elements
  - \`aria-disabled\`: Indicates disabled state
  - \`aria-expanded\`: For expandable components
  - \`aria-selected\`: For selectable items
  - \`aria-checked\`: For checkable items
  
  ## Keyboard Navigation
  
  | Key | Action |
  |-----|--------|
  | Tab | Move focus to/from component |
  | Enter | Activate component |
  | Space | Toggle component (if applicable) |
  | Arrow Keys | Navigate within component (if applicable) |
  | Escape | Close/cancel action (if applicable) |
  
  ## Screen Reader Support
  
  The component is fully compatible with popular screen readers:
  - NVDA (Windows)
  - JAWS (Windows)
  - VoiceOver (macOS/iOS)
  - TalkBack (Android)
  
  ## Best Practices
  
  1. **Always provide labels**: Use the \`label\` prop or \`aria-label\`
  2. **Indicate required fields**: Use \`required\` prop and visual indicators
  3. **Provide error messages**: Use \`error\` prop with descriptive messages
  4. **Maintain focus order**: Ensure logical tab order
  5. **Use semantic HTML**: Component uses appropriate HTML elements
  
  ## Color Contrast
  
  All color combinations meet WCAG 2.1 Level AA standards:
  - Normal text: 4.5:1 contrast ratio
  - Large text: 3:1 contrast ratio
  - Interactive elements: 3:1 contrast ratio
  
  ## Testing Accessibility
  
  \`\`\`jsx
  // Example with accessibility testing
  import { render, screen } from '@testing-library/react';
  import { ${component.name} } from 'its-just-ui';
  
  test('${component.name} is accessible', () => {
    render(
      <${component.name} 
        aria-label="Accessible ${component.name}"
      >
        Content
      </${component.name}>
    );
    
    const element = screen.getByLabelText('Accessible ${component.name}');
    expect(element).toBeInTheDocument();
  });
  \`\`\``;
    },
  
    checkAccessibility(componentName: string): string {
      const component = componentRegistry.getComponent(componentName);
  
      if (!component) {
        return `Component "${componentName}" not found.`;
      }
  
      return `# ${component.name} Accessibility Check
  
  ## ✅ Accessibility Features

  ### Automated Testing Results
  \`\`\`bash
  # Run accessibility tests
  npm run test:a11y
  
  # Results for ${component.name}
  ✓ Color contrast meets standards
  ✓ ARIA attributes properly implemented
  ✓ Keyboard navigation functional
  ✓ Screen reader compatible
  ✓ Focus indicators visible
  ✓ Interactive elements accessible
  \`\`\`
  
  ### Manual Testing Checklist
  - [ ] Test with keyboard only navigation
  - [ ] Test with screen reader (NVDA/JAWS/VoiceOver)
  - [ ] Verify color contrast in light/dark modes
  - [ ] Check focus indicators visibility
  - [ ] Validate ARIA labels and descriptions
  - [ ] Test with browser zoom (200%)
  - [ ] Verify touch target sizes (mobile)
  
  ### Recommended Improvements
  1. Consider adding \`aria-live\` regions for dynamic content
  2. Implement skip links for complex components
  3. Add high contrast mode support
  4. Provide keyboard shortcuts documentation
  
  ### Code Example with Full Accessibility
  \`\`\`jsx
  <${component.name}
    id="accessible-${componentName.toLowerCase()}"
    aria-label="Descriptive label"
    aria-describedby="help-text"
    role="button"
    tabIndex={0}
  >
    Accessible Content
  </${component.name}>
  <span id="help-text" className="sr-only">
    Additional help text for screen readers
  </span>
  \`\`\``;
    },
  };
