Second Brain Triage

Intelligent information triage system based on Tiago Forte's PARA method (Projects/Areas/Resources/Archive) for automatic categorization and priority scoring. Use when the user wants to organize notes, classify content, prioritize tasks, or manage their second brain knowledge base.

Intelligent information triage system based on Tiago Forte's PARA method (Projects/Areas/Resources/Archive) for automatic categorization and priority scoring.

Features

• Content Analyzer: Automatically identify content types (articles, videos, tasks, code, etc.) and extract metadata
• PARA Classifier: Smart categorization into Projects/Areas/Resources/Archive
• Urgency Scorer: Multi-dimensional algorithm to evaluate processing priority (1-10 scale)
• Relatedness Detector: Discover similarities and relationships between content items

Usage

Basic Usage

const { SecondBrainTriage } = require('./src');

const triage = new SecondBrainTriage();

// Triage single content item
const result = triage.triage('TODO: Complete project report, due this Friday');
console.log(result.summary);
// {
//   title: "Complete project report, due this Friday",
//   type: "task",
//   category: "Projects",
//   urgency: "High urgency",
//   urgencyScore: 8,
//   action: "Process today: recommend completing within 24 hours"
// }

// Batch triage
const results = triage.triageBatch([
  'https://github.com/user/repo',
  'Notes on learning React Hooks',
  'TODO: Fix login bug',
]);

// Export report
const report = triage.exportReport(results, 'markdown');

CLI Usage

# Analyze single content item
node scripts/triage.js "Text content to process"

# Analyze file
node scripts/triage.js --file ./notes.txt

# Batch analysis
node scripts/triage.js --batch ./items.json --output report.md

Classification Guide

PARA Categories

Category	Description	Examples
Projects	Items with clear goals and deadlines	"Develop new feature", "Complete report"
Areas	Long-term responsibilities and standards	"Health management", "Skill development"
Resources	Topics of interest and reference materials	"Technical articles", "Learning notes"
Archive	Completed or inactive items	"Finished projects", "Historical records"
Inbox	Temporary storage for uncategorized items	Content that cannot be determined

Urgency Levels

Score	Level	Description	Recommendation
9-10	Critical	Process immediately	Take action now
7-8	High	Process today	Complete within 24 hours
5-6	Medium	Process this week	Schedule within the week
3-4	Low	Low priority	Can be deferred
1-2	Minimal	Archive for reference	No immediate action needed

Scoring Algorithm

Urgency Scoring Dimensions

1. Time Sensitivity (30%): Deadlines, time keywords
2. Action Requirement (25%): Action verbs like must/plan/maybe
3. Consequences (20%): Potential impact of not processing
4. Context Signals (15%): Blockers, external dependencies
5. User Preferences (10%): Configurable priorities

Relatedness Detection

• Tag similarity (Jaccard coefficient)
• Title/description text similarity (Cosine similarity)
• Semantic similarity (based on semantic groups)
• Type matching

Configuration Options

const triage = new SecondBrainTriage({
  enableRelatedness: true,    // Enable relatedness detection
  urgencyThreshold: 5,        // Urgency threshold
});

Output Formats

Supported export formats:

• JSON (complete data)
