|
||||
|
||||
## Key Implementation Decisions
|
||||
|
||||
### 1. Single File Output (bundle.html)
|
||||
|
||||
**Decision**: Generate single self-contained HTML file rather than multi-file output
|
||||
|
||||
**Rationale**:
|
||||
- ✅ Easy deployment - single file to copy anywhere
|
||||
- ✅ No build process required for end-user
|
||||
- ✅ Works in email, documentation, LMS systems
|
||||
- ✅ No broken links or missing assets
|
||||
- ✅ Git-friendly (single file for version control)
|
||||
|
||||
**Implementation**:
|
||||
- Uses Parcel bundler with target: "browser"
|
||||
- Inlines all CSS (Tailwind + custom styles)
|
||||
- Inlines all JavaScript (React + dependencies)
|
||||
- Result: ~300KB single HTML file
|
||||
|
||||
### 2. Exact Code Preservation
|
||||
|
||||
**Decision**: Copy code examples character-for-character from documentation
|
||||
|
||||
**Rationale**:
|
||||
- ✅ Maintains learning fidelity - learners use documented code
|
||||
- ✅ Reduces bugs - no transcription errors
|
||||
- ✅ Simplifies attribution - exact match proves source
|
||||
- ✅ Future-proofs - code works as documented
|
||||
|
||||
**Implementation Process**:
|
||||
1. When fetching documentation, prioritize pages with concrete code
|
||||
2. Copy code blocks directly into CodeBlock components
|
||||
3. Never paraphrase or "improve" code
|
||||
4. Include comments/annotations from original
|
||||
5. Note any limitations in inline comments if needed
|
||||
|
||||
### 3. Progressive Disclosure Pattern
|
||||
|
||||
**Decision**: Order concepts from simple → complex, never introducing unexplained dependencies
|
||||
|
||||
**Rationale**:
|
||||
- ✅ Prevents cognitive overload
|
||||
- ✅ Allows learners to stop at any point with complete knowledge
|
||||
- ✅ Enables skipping advanced sections for basic users
|
||||
- ✅ Matches how documentation should be read
|
||||
|
||||
**Implementation Approach**:
|
||||
1. Extract all concepts from documentation
|
||||
2. Create dependency graph (Feature A requires Feature B knowledge)
|
||||
3. Topological sort: ensure all prerequisites satisfy before introducing concept
|
||||
4. Group related concepts into learning units
|
||||
5. Verify each unit is coherent and self-contained
|
||||
|
||||
### 4. Attribution & Respect
|
||||
|
||||
**Decision**: Always preserve original authorship and provide clear sourcing
|
||||
|
||||
**Rationale**:
|
||||
- ✅ Ethical - respects original authors' work
|
||||
- ✅ Legal - maintains license compliance
|
||||
- ✅ Educational - learners know source of information
|
||||
- ✅ Quality assurance - shows where to find authoritative information
|
||||
|
||||
**Implementation Details**:
|
||||
- Include source URL prominently
|
||||
- Quote documentation with "According to [source]: '...'"
|
||||
- Note which section each concept comes from
|
||||
- Include license information if provided
|
||||
- Link to original documentation when possible
|
||||

|
||||
|
||||
## Technology Stack Rationale
|
||||
|
||||
### React + TypeScript
|
||||
|
||||
**Why**:
|
||||
- Component-based architecture maps well to learning sections
|
||||
- TypeScript ensures type safety in complex UI state
|
||||
- Rich ecosystem for educational UI patterns
|
||||
- Easy to refactor and enhance sections independently
|
||||
|
||||
### Tailwind CSS
|
||||
|
||||
**Why**:
|
||||
- Responsive design with minimal custom CSS
|
||||
- Dark theme suitable for code display
|
||||
- `text-left` utility classes solve alignment issues
|
||||
- Composable utilities for consistent styling
|
||||
|
||||
### Shadcn/ui
|
||||
|
||||
**Why**:
|
||||
- Pre-built accessible components (Card, Tabs, Badge, Button)
|
||||
- Based on Radix UI - production-quality foundations
|
||||
- Easy to customize and extend
|
||||
- Reduces boilerplate code for common patterns
|
||||
|
||||
### Parcel Bundler
|
||||
|
||||
**Why**:
|
||||
- Zero-config build system
|
||||
- Automatically inlines assets into single file
|
||||
- Fast rebuild times during development
|
||||
- Produces optimized single HTML output
|
||||
|
||||
---
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Pattern 1: CodeBlock Component
|
||||
|
||||
Used for displaying code snippets with copy functionality:
|
||||
|
||||
```typescript
|
||||
<CodeBlock
|
||||
code={exactCodeFromDocs}
|
||||
language="python"
|
||||
/>
|
||||
```
|
||||
|
||||
**Features**:
|
||||
- Syntax highlighting by language
|
||||
- Dark background (`bg-slate-950`)
|
||||
- Copy button with visual feedback
|
||||
- Line numbers (optional)
|
||||
- Text-left alignment (Tailwind + CSS)
|
||||
|
||||
**Styling Considerations**:
|
||||
- Must explicitly set `text-left` (not inherited)
|
||||
- Pre element needs `text-left` class
|
||||
- Code element needs `text-left` class
|
||||
- Ensures alignment regardless of parent styles
|
||||
|
||||
### Pattern 2: APIExample Component
|
||||
|
||||
Used for API documentation tutorials:
|
||||
|
||||
```typescript
|
||||
<APIExample
|
||||
title="Add Memory"
|
||||
endpoint="/v1/memories"
|
||||
method="POST"
|
||||
curlCommand={exactCurlFromDocs}
|
||||
requestBody={exampleRequest}
|
||||
responseExample={exampleResponse}
|
||||
/>
|
||||
```
|
||||
|
||||
**Features**:
|
||||
- Tabbed interface (cURL, Request, Response)
|
||||
- Each tab contains copyable code blocks
|
||||
- Shows realistic API interaction flow
|
||||
- Helps readers understand before/after states
|
||||
|
||||
### Pattern 3: LearningObjective
|
||||
|
||||
Every section starts with clear learning goal:
|
||||
|
||||
```typescript
|
||||
<LearningObjective
|
||||
text="After this section, you'll understand Feature X and when to use it"
|
||||
/>
|
||||
```
|
||||
|
||||
**Purpose**:
|
||||
- Sets learner expectations
|
||||
- Provides clear success criteria
|
||||
- Helps learners focus attention
|
||||
- Enables self-assessment
|
||||
|
||||
### Pattern 4: DocumentationQuote
|
||||
|
||||
Highlights exact documentation statements:
|
||||
|
||||
```typescript
|
||||
<DocumentationQuote
|
||||
quote="Exact text from documentation"
|
||||
source="Documentation Section Name"
|
||||
url="Link to documentation page"
|
||||
/>
|
||||
```
|
||||
|
||||
**Styling**:
|
||||
- Distinct visual treatment (border, background)
|
||||
- Shows source attribution
|
||||
- Maintains reading flow while highlighting importance
|
||||
|
||||

|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Phase 1: Content Accuracy Testing
|
||||
- [ ] Verify each code example matches documentation exactly
|
||||
- [ ] Check that all curl commands work (can test with curl)
|
||||
- [ ] Verify Python SDK examples can be imported
|
||||
- [ ] Ensure all URLs in references still work
|
||||
|
||||
### Phase 2: Progression Testing
|
||||
- [ ] Can a learner read section 1 in isolation?
|
||||
- [ ] Do all prerequisites exist before introducing a concept?
|
||||
- [ ] Are there any confusing jumps in complexity?
|
||||
- [ ] Can someone stop after any section with complete understanding?
|
||||
|
||||
### Phase 3: UX Testing
|
||||
- [ ] Do code blocks display correctly on mobile?
|
||||
- [ ] Can all code be copied successfully?
|
||||
- [ ] Is navigation intuitive?
|
||||
- [ ] Is dark theme readable for extended periods?
|
||||
- [ ] Are code blocks left-aligned (not centered)?
|
||||
|
||||
### Phase 4: Attribution Testing
|
||||
- [ ] Every concept has documentation quote
|
||||
- [ ] Source sections are clearly noted
|
||||
- [ ] Original author/URL is credited
|
||||
- [ ] No claims made beyond what documentation states
|
||||
|
||||

|
||||
|
||||
## Known Limitations
|
||||
|
||||
### WebFetch Tool Behavior
|
||||
- Returns AI-summarized markdown, not raw documentation
|
||||
- Workaround: Fetch pages with higher code density (Quickstart vs Introduction)
|
||||
- Limitation: Can't get completely raw HTML via WebFetch
|
||||
|
||||
### Code Example Availability
|
||||
- Only tutorials can include code that exists in documentation
|
||||
- Can't invent "example" code beyond what's documented
|
||||
- When documentation lacks examples, must note this limitation
|
||||
|
||||
### Interactive Execution
|
||||
- Code examples are display-only, not executable in artifact
|
||||
- Workaround: Include clear instructions for running examples locally
|
||||
- Can't execute external APIs from bundled artifact (CORS restrictions)
|
||||
|
||||
---
|
||||
|
||||
## Maintenance Guidelines
|
||||
|
||||
### When to Update
|
||||
|
||||
Update the tutorial when:
|
||||
1. Documentation gets major updates
|
||||
2. Code examples are found to be outdated
|
||||
3. New versions released (API changes, deprecated features)
|
||||
4. User provides feedback about confusing sections
|
||||
5. Progression logic needs improvement
|
||||
|
||||
### Version Control
|
||||
|
||||
Always commit tutorials with:
|
||||
```
|
||||
Documentation Tutorial: [Documentation Name] - [Date]
|
||||
|
||||
- Updated to match [Documentation Version]
|
||||
- Added/Modified/Removed: [Key changes]
|
||||
- Tested with: [Test details]
|
||||
|
||||
Source: [Documentation URL]
|
||||
```
|
||||
|
||||
### Testing Before Deployment
|
||||
|
||||
```bash
|
||||
# 1. Build the artifact
|
||||
npm run build # or parcel build
|
||||
|
||||
# 2. Open in browser
|
||||
open bundle.html
|
||||
|
||||
# 3. Test on each section:
|
||||
# - Code blocks copy correctly
|
||||
# - All links work
|
||||
# - No broken styling
|
||||
# - Navigation functions
|
||||
|
||||
# 4. Test a few code examples locally
|
||||
# - Copy curl commands, run them
|
||||
# - Copy Python code, test imports
|
||||
# - Verify output matches documented behavior
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Extending the Skill
|
||||
|
||||
### To Support New Documentation
|
||||
|
||||
1. **Fetch the documentation**
|
||||
- Use WebFetch for initial content
|
||||
- Use MCP Exa or direct fetch for richer content
|
||||
- Look for Quickstart/Getting Started sections first
|
||||
|
||||
2. **Analyze structure**
|
||||
- Identify all sections and features
|
||||
- Extract exact quotes for each feature
|
||||
- Collect all code examples
|
||||
- Map dependencies
|
||||
|
||||
3. **Design progression**
|
||||
- Zero-prerequisite topics first
|
||||
- Build dependency graph
|
||||
- Order from simple → complex
|
||||
- Group related concepts
|
||||
|
||||
4. **Build artifact**
|
||||
- Create React component with sections
|
||||
- Use CodeBlock for code examples
|
||||
- Use APIExample for API docs
|
||||
- Include LearningObjective for each section
|
||||
|
||||
5. **Test thoroughly**
|
||||
- Content accuracy (code matches docs)
|
||||
- Progression logic (no unexplained jumps)
|
||||
- UX quality (styling, alignment, copy buttons)
|
||||
- Attribution (all sources credited)
|
||||
|
||||
### To Add New Component Types
|
||||
|
||||
Example: Adding a new "ConceptDiagram" component for architecture diagrams
|
||||
|
||||
```typescript
|
||||
// 1. Create component
|
||||
function ConceptDiagram({ title, svgUrl, description }) {
|
||||
return (
|
||||
<div className="my-4 p-4 bg-slate-900 rounded-lg">
|
||||
<h4>{title}</h4>
|
||||
<img src={svgUrl} alt={title} />
|
||||
<p>{description}</p>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
// 2. Add to main content flow
|
||||
<ConceptDiagram
|
||||
title="API Request Flow"
|
||||
svgUrl="./diagrams/api-flow.svg"
|
||||
description="How requests flow through the system"
|
||||
/>
|
||||
|
||||
// 3. Test rendering and styling
|
||||
// 4. Update SKILL.md with new pattern
|
||||
// 5. Document in this file
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Bundle Size
|
||||
- Target: < 400KB for single HTML file
|
||||
- Current: ~300KB (typical)
|
||||
- Optimization: Parcel handles minification automatically
|
||||
|
||||
### Load Time
|
||||
- Single file loads faster than multi-file artifact
|
||||
- No additional HTTP requests after page load
|
||||
- Dark theme reduces perceived latency (less "flashing")
|
||||
|
||||
### Rendering Performance
|
||||
- React handles DOM efficiently
|
||||
- Syntax highlighting done at build time
|
||||
- No dynamic code evaluation
|
||||
|
||||
---
|
||||
|
||||
## Accessibility Considerations
|
||||
|
||||
### Currently Implemented
|
||||
- ✅ Semantic HTML structure
|
||||
- ✅ Color contrast in dark theme
|
||||
- ✅ Keyboard navigation via Tab
|
||||
- ✅ Alt text for diagrams (when present)
|
||||
- ✅ Code blocks marked with language type
|
||||
|
||||
### Could Be Enhanced
|
||||
- [ ] ARIA labels for interactive elements
|
||||
- [ ] Transcripts for any embedded video
|
||||
- [ ] Dyslexia-friendly font option
|
||||
- [ ] High contrast mode toggle
|
||||
- [ ] Screen reader optimization for code blocks
|
||||
|
||||
---
|
||||
|
||||
## Debugging Guide
|
||||
|
||||
### "Code block styling looks wrong"
|
||||
|
||||
Check:
|
||||
1. Is `text-left` class present on CodeBlock div?
|
||||
2. Is parent element using `text-align: center`?
|
||||
3. Check browser dev tools - which CSS rule is winning?
|
||||
|
||||
Fix: Add explicit `!important` to text-left if inheritance issue:
|
||||
```css
|
||||
code, pre {
|
||||
text-align: left !important;
|
||||
}
|
||||
```
|
||||
|
||||
### "Copy button not working"
|
||||
|
||||
Check:
|
||||
1. Is Clipboard API available? (all modern browsers)
|
||||
2. Does code block have a unique ID?
|
||||
3. Check browser console for JavaScript errors
|
||||
|
||||
Test:
|
||||
```javascript
|
||||
// In browser console
|
||||
navigator.clipboard.writeText("test text")
|
||||
.then(() => console.log("Copy works"))
|
||||
.catch(e => console.log("Copy failed:", e))
|
||||
```
|
||||
|
||||
### "Documentation quote not showing"
|
||||
|
||||
Check:
|
||||
1. Is quote text actually in documentation?
|
||||
2. Is URL accessible?
|
||||
3. Check for HTML entity encoding issues
|
||||
|
||||
### "Navigation doesn't work"
|
||||
|
||||
Check:
|
||||
1. Are scroll IDs matching section anchor IDs?
|
||||
2. Is React Router properly configured?
|
||||
3. Check browser console for routing errors
|
||||
