AI Engine
Task Parsing Algorithm
The AI engine analyzes task descriptions and generates structured subtask breakdowns:
// Example: "Build Dashboard"
{
"subtasks": [
{ "name": "Design wireframe and layout", "hours": 3, "priority": "high" },
{ "name": "Implement component structure", "hours": 4, "priority": "high" },
{ "name": "Add interactive charts", "hours": 5, "priority": "medium" },
{ "name": "Style with CSS/Tailwind", "hours": 3, "priority": "medium" },
{ "name": "Test responsiveness", "hours": 2, "priority": "low" }
]
}
Risk Calculation Formula
Total Hours = Σ(subtask hours)
Corrected Hours = Total Hours × 1.4 (planning fallacy correction)
Effective Hours = Days Until Deadline × Hours Per Day × Energy Level
Raw Probability = (Effective Hours / Corrected Hours) × 100
Uncertainty Penalty = min(20, subtask_count × 2)
Final Probability = max(0, min(100, Raw Probability - Uncertainty Penalty))
Risk Levels
- Low Risk (Green): 70-100% completion probability
- Medium Risk (Yellow): 40-69% completion probability
- High Risk (Red): 0-39% completion probability

// Adjust planning fallacy factor
const planningFallacyFactor = 1.4; // Default: 1.4 (40% buffer)
// Change uncertainty penalty
const uncertaintyPenalty = Math.min(20, subtasks.length * 2);
// Modify risk thresholds
if (probability >= 70) riskLevel = 'low';
else if (probability >= 40) riskLevel = 'medium';
else riskLevel = 'high';
Styling Modifications
All styles are in index.html <style> section and Tailwind classes.
