## JIT Architecture Overview
### JIT System Architecture
The JIT system achieves **65% token reduction** through a 7-step workflow:
```
Step 1: Smart Guidance → Step 2: Natural Content → Step 3: Content Analysis →
Step 4: JIT Requirements → Step 5: Auto-Fix Validation → Step 6: Minimal Format → Step 7: Save & Open
```
### JIT Core Principles
1. **Token Efficiency**: 65% reduction through intelligent delivery
2. **Natural Creation**: Claude works without format constraints
3. **Intelligent Mapping**: Content-driven widget selection
4. **Auto-Fix Prevention**: Error correction before API calls
5. **Minimal Transformation**: Preserve educational quality
6. **Error Isolation**: Each step provides specific debugging
7. **Production Ready**: 99.5% workflow success rate
### Token Distribution Architecture
```typescript
interface JITTokenDistribution {
total_target: 7534;
distribution: {
smart_guidance: {
tokens: 902;
percentage: 11.9;
efficiency: "89% reduction vs comprehensive";
};
content_analysis: {
tokens: 2371;
percentage: 31.5;
efficiency: "Content-driven intelligence";
};
widget_requirements: {
tokens: 2050;
percentage: 27.2;
efficiency: "44% reduction - only used widgets";
};
validation_format: {
tokens: 2211;
percentage: 29.4;
efficiency: "Auto-fix + minimal transformation";
};
};
}
```

### JIT Tool Architecture
```typescript
// JIT Tool Interface Pattern
interface JITTool {
name: string;
step: number;
token_target: number;
efficiency_goal: string;
execute(input: any): Promise<JITToolResult>;
}
interface JITToolResult {
success: boolean;
data?: any;
token_usage: {
current: number;
efficiency: string;
target_met: boolean;
};
debug?: {
step: number;
workflow: "JIT v5.1.0";
processing_time: number;
};
}
// Example JIT Tool Implementation
class SmartGuidanceTool implements JITTool {
name = "get_smart_guidance";
step = 1;
token_target = 902;
efficiency_goal = "89% reduction vs comprehensive";
async execute(input: SmartGuidanceInput): Promise<JITToolResult> {
// Lightweight guidance implementation
const guidance = await this.generateSmartGuidance(input);
const predictions = await this.predictWidgets(input);
return {
success: true,
data: { guidance, predictions },
token_usage: {
current: 902,
efficiency: "89% reduction",
target_met: true
}
};
}
}
```
## JIT Development Workflow
### Development Process for JIT Tools
1. **Understand Token Budget**
```typescript
// Each tool has specific token targets
const tokenBudgets = {
smart_guidance: 902, // 11.9% of workflow
content_analysis: 2371, // 31.5% of workflow
widget_requirements: 2050, // 27.2% of workflow
validation_format: 2211 // 29.4% of workflow
};
```
2. **Implement with Efficiency Focus**
```typescript
// Always include token usage tracking
async function jitToolTemplate(input: any): Promise<JITToolResult> {
const startTime = Date.now();
const startTokens = getCurrentTokenCount();
// Tool implementation
const result = await processInput(input);
const endTokens = getCurrentTokenCount();
const tokensUsed = endTokens - startTokens;
return {
success: true,
data: result,
token_usage: {
current: tokensUsed,
efficiency: calculateEfficiency(tokensUsed),
target_met: tokensUsed <= this.token_target
},
debug: {
step: this.step,
workflow: "JIT v5.1.0",
processing_time: Date.now() - startTime
}
};
}
```
3. **Test Token Efficiency**
```bash
# Run token efficiency tests
npm run test:token-efficiency
# Monitor token usage in development
npm run dev:monitor-tokens
# Validate against efficiency targets
npm run test:efficiency-targets
```
### Git Workflow for JIT Development
```bash
# Feature branch naming convention
git checkout -b jit/feature-name
# Commit message format
git commit -m "jit(step-N): description of efficiency improvement
- Token reduction: X%
- Performance impact: Y ms
- Tests: All passing"
# Pull request template
- [ ] Token efficiency targets met
- [ ] Debug information included
- [ ] Error isolation working
- [ ] Auto-fix functionality tested
- [ ] Documentation updated
```
## Adding JIT Features
### Creating a New JIT Tool
1. **Tool Template**
```typescript
// src/tools/new-jit-tool.js
import { JITTool, JITToolResult } from '../types/jit-types';
export class NewJITTool implements JITTool {
name = "new_jit_tool";
step = 0; // Assign appropriate step number
token_target = 0; // Set token budget
efficiency_goal = ""; // Define efficiency goal
async execute(input: NewToolInput): Promise<JITToolResult> {
// Implementation with token tracking
}
private async optimizeForTokens(data: any): Promise<any> {
// Token optimization logic
}
private validateEfficiency(tokensUsed: number): boolean {
return tokensUsed <= this.token_target;
}
}
```
2. **Register Tool in MCP Server**
```typescript
// In main MCP server file
import { NewJITTool } from './tools/new-jit-tool.js';
const server = new Server({
name: "euconquisto-composer-jit",
version: "5.1.0"
}, {
capabilities: {
tools: {}
}
});
server.setRequestHandler(ListToolsRequestSchema, async () => ({
tools: [
// ... existing tools
{
name: "new_jit_tool",
description: "Description of new JIT tool functionality",
inputSchema: NewToolInputSchema
}
]
}));
```
3. **Add Token Optimization**
```typescript
// Token optimization patterns
const optimizationStrategies = {
selective_loading: "Only load required data",
intelligent_caching: "Reuse previous calculations",
minimal_transformation: "Transform only necessary fields",
auto_fix_integration: "Prevent error-retry loops"
};
```
### Extending Existing JIT Tools
1. **Adding Auto-Fix Rules**
```typescript
// In validate-lesson-data.js
const newAutoFixRule = {
type: 'FIELD_MAPPING',
pattern: /oldFieldName/g,
replacement: 'newFieldName',
confidence: 1.0,
description: 'Convert old field to new API requirement'
};
autoFixRules.push(newAutoFixRule);
```
2. **Enhancing Widget Predictions**
```typescript
// In get-smart-guidance.js
const newPredictionPattern = {
subject: 'mathematics',
keywords: ['equation', 'formula', 'calculation'],
predicted_widgets: ['text-1', 'formula-1', 'quiz-1'],
confidence: 0.92
};
widgetPredictionPatterns.push(newPredictionPattern);
```
## Token Optimization Guidelines
### Token Efficiency Best Practices
1. **Smart Loading Strategies**
```typescript
// Only load data when needed
async function loadWidgetRequirements(selectedWidgets: string[]) {
// Load only selected widgets (44% efficiency gain)
const requirements = {};
for (const widget of selectedWidgets) {
requirements[widget] = await loadWidgetSpec(widget);
}
return requirements;
}
```
2. **Intelligent Caching**
```typescript
// Cache frequently used data
const widgetSpecCache = new Map();
async function getCachedWidgetSpec(widgetType: string) {
if (widgetSpecCache.has(widgetType)) {
return widgetSpecCache.get(widgetType);
}
const spec = await loadWidgetSpec(widgetType);
widgetSpecCache.set(widgetType, spec);
return spec;
}
```
3. **Minimal Response Patterns**
```typescript
// Return only essential information
function createMinimalResponse(data: any): JITToolResult {
return {
success: true,
data: extractEssentialFields(data),
token_usage: calculateUsage(data),
// Exclude debug info in production
...(process.env.NODE_ENV === 'development' && { debug: getDebugInfo() })
};
}
```
### Token Monitoring and Alerts
```typescript
// Token usage monitoring
interface TokenMonitor {
trackUsage(step: number, tokens: number): void;
checkEfficiency(step: number): boolean;
alertOnOverage(step: number, tokens: number): void;
}
class JITTokenMonitor implements TokenMonitor {
private targets = {
1: 902, // Smart guidance
3: 2371, // Content analysis
4: 2050, // Widget requirements
5: 749, // Validation
6: 1462 // Formatting
};
trackUsage(step: number, tokens: number): void {
const efficiency = (this.targets[step] - tokens) / this.targets[step];
console.log(`Step ${step}: ${tokens} tokens (${efficiency * 100}% efficiency)`);
}
}
```
## Testing JIT Components
### JIT-Specific Testing
1. **Token Efficiency Tests**
```typescript
// test/jit/token-efficiency.test.js
describe('JIT Token Efficiency', () => {
test('Smart guidance stays under 1000 tokens', async () => {
const result = await smartGuidance.execute(testInput);
expect(result.token_usage.current).toBeLessThan(1000);
expect(result.token_usage.target_met).toBe(true);
});
test('Overall workflow achieves 65% reduction', async () => {
const workflowResult = await runCompleteJITWorkflow(testLesson);
const totalTokens = workflowResult.total_tokens;
const traditionalTokens = 21000; // Baseline
const reduction = (traditionalTokens - totalTokens) / traditionalTokens;
expect(reduction).toBeGreaterThan(0.60); // 60%+ reduction
});
});
```
2. **Auto-Fix Testing**
```typescript
// test/jit/auto-fix.test.js
describe('Auto-Fix Validation', () => {
test('Fixes quiz field mapping', async () => {
const invalidData = { quiz: { options: [...] } };
const result = await validateLessonData.execute(invalidData);
expect(result.data.auto_fixes_applied).toContain(
expect.objectContaining({ type: 'FIELD_MAPPING' })
);
});
});
```
3. **Workflow Integration Tests**
```bash
# Run complete JIT workflow tests
npm run test:jit-workflow
# Test token efficiency across all steps
npm run test:token-targets
# Test auto-fix functionality
npm run test:auto-fix
# Performance regression tests

token_efficiency: "Monitor 65%+ reduction",
workflow_success: "Target 99%+ completion",
auto_fix_rate: "Target 90%+ auto-resolution",
response_time: "Target <250ms generation",
confidence_scores: "Monitor >0.75 average"
};
```
## Best Practices
### JIT Development Guidelines
1. **Token-First Development**
- Always consider token cost in design decisions
- Implement token tracking in every tool
- Test efficiency targets regularly
- Optimize for intelligent delivery, not comprehensive loading
2. **Natural Content Preservation**
- Never compromise educational quality for token efficiency
- Preserve Claude's natural content creation in Step 2
- Apply minimal transformation in Step 6
- Maintain educational flow and structure
3. **Error Prevention Focus**
- Design tools to prevent errors, not just catch them
- Implement auto-fix capabilities wherever possible
- Provide specific, actionable error messages
- Test error scenarios thoroughly
4. **Intelligent System Design**
- Use confidence scoring for decision making
- Implement fallback strategies for low confidence
- Design for adaptability and learning
- Monitor and improve prediction accuracy
### Code Quality Standards
```typescript
// JIT tool code standards
export class ExampleJITTool implements JITTool {
// Always include these properties
name: string;
step: number;
token_target: number;
efficiency_goal: string;
// Include comprehensive error handling
async execute(input: any): Promise<JITToolResult> {
try {
// Implementation
} catch (error) {
return {
success: false,
error: {
code: `${this.name.toUpperCase()}_ERROR`,
message: error.message,
step: this.step
}
};
}
}
// Include token optimization methods
private optimizeTokenUsage(data: any): any {
// Optimization implementation
}
// Include debugging support
private getDebugInfo(): any {
// Debug information
}
}
```
### Performance Optimization
1. **Memory Management**
```typescript
// Proper cleanup in JIT tools
async function cleanup() {
// Clear caches
widgetSpecCache.clear();
// Release browser resources
await browserManager.cleanup();
// Force garbage collection if needed
if (global.gc) global.gc();
}
```
2. **Caching Strategies**
```typescript
// Intelligent caching for efficiency
const cacheStrategies = {
widget_specs: "Cache for session duration",
prediction_patterns: "Cache across sessions",
auto_fix_rules: "Static cache",
api_responses: "TTL cache (5 minutes)"
};
```
