🎯 Overview

Thread Session Manager is a VS Code extension that intelligently breaks down large AI assistant tasks into isolated thread sessions, dramatically reducing token usage while maintaining context quality. With special integration for Bob/Cline and support for other AI assistants, it provides a seamless experience for managing complex development workflows.

Key Features

• 🧵 Intelligent Thread Management - Automatic, manual, and AI-suggested thread creation
• 📊 Real-time Token Tracking - Monitor usage with predictive alerts
• 🎯 Minimal Context Isolation - Each thread maintains only essential context
• 🌳 Visual Thread Hierarchy - Tree and timeline views for easy navigation
• 🔀 Advanced Operations - Branch, merge, and compare threads
• 📈 Analytics Dashboard - Track efficiency and token savings
• 🤖 Bob Integration - Seamless integration with Bob/Cline AI assistant
• 🔌 Extensible Architecture - Support for multiple AI assistants

2. Monitor Token Usage

   Check status bar: [🧵 Thread Name] [📊 45.2K tokens] [⚠️ 90%]
   Extension alerts you when approaching limits
   

3. Split When Needed

   Accept AI suggestion or manually create new thread
   Minimal context automatically transferred
   Continue with fresh token budget

Key Concepts

Thread Sessions

Isolated conversation contexts with independent token budgets. Each thread maintains minimal shared context (≤1000 tokens) while preserving essential decisions, artifacts, and dependencies.

Token Tracking

Real-time monitoring of token usage with configurable thresholds:

• Warning: 80% (40K tokens)
• Critical: 90% (45K tokens)
• Limit: 100% (50K tokens)

Context Isolation

Each thread receives only essential context:

• Key Decisions (40% of budget) - Critical architectural choices
• Artifacts (40% of budget) - Generated files and code
• Dependencies (20% of budget) - Required packages and services

AI-Driven Suggestions

Machine learning analyzes your conversation to:

• Detect optimal thread boundaries
• Estimate task complexity
• Extract logical subtasks
• Suggest thread names
