FSS Link 🔗

Spin up links. Get work done. 🚀

FSS Link is a portable, scriptable agent that links tools, models, and knowledge into multi-instance workflows. Install anywhere with Node.js, launch 1-8 agents at once, feed them templated tasks, and watch them go.

• Lightweight distribution (~15 MB bundle, requires Node.js 20+)
• Spawn many agents with structured prompts
• Portable Mini-RAG indices that travel with your projects
• Local-first with LM Studio/Ollama priority
• Professional tools built in TypeScript for seamless integration

🎯 Why "Link"?

Link connects things—tools, models, tasks, and knowledge. FSS Link is a lightweight distribution that runs wherever Node.js is installed. Start an agent, or spawn eight in parallel with templated prompts. Each project carries its own Mini-RAG index, so knowledge travels with the work.

🚀 Quick Start

# Interactive mode
fss-link

# Single-shot task
fss-link run "Audit the repo for security keys and open PR fixes."

# Launch 6 parallel agents with templated plan
fss-link spawn --count 6 --template ./templates/regression.yml

# Portable RAG - indexes travel with projects
cd project && fss-link rag index . && fss-link rag query "error handling"

📦 Installation

FSS Link v1.0.13 is now published to NPM! Install it globally for the best experience:

# Method 1: NPM Global Install (Recommended)
npm install -g fss-link

# Now you can use fss-link anywhere
fss-link --help
fss-link --version  # Should show v1.0.13

🔄 Node.js Version Requirements

FSS Link requires Node.js 20+. If you have an older version, upgrade first:

# Check your current Node version
node --version

# If you have Node 18 or older, upgrade to Node 20:
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt-get install nodejs -y

# Verify upgrade
node --version  # Should show v20.x.x
npm --version   # Should show v10.x.x

# Method 2: Clone and Build from Source (Development)
git clone http://192.168.1.3:3000/foxadmin/fss-link.git
cd fss-link
npm install
npm run build

# Install globally for 'fss-link' command
npm link

# Now you can use fss-link anywhere
fss-link --help

# Method 3: Run without installing globally
npx fss-link
# OR from source
cd fss-link
npx fss-link

✅ Note: FSS Link is now published to npm as fss-link v1.0.13!

🔧 Enhanced Features & Tools

This agent extends FSS Link v0.0.10+ with professional development tools and intelligent workflow automation:

🧠 TypeScript Mini-RAG System

Built-in semantic search that travels with your projects. No Python dependencies, no setup complexity.

• Deep Semantic Search: Find code by describing what it does, not just what it's called
• Cross-Reference Analysis: Discover how different parts of the system interact
• Context-Aware Suggestions: Get recommendations based on the entire project context
• Portable Indices: Knowledge travels with your projects

📋 Enhanced Task Management

Built on FSS Link's native TodoWrite tool with professional enhancements for complex development workflows.

• Persistent Task Lists: Never lose track of what needs to be done
• Visual Progress Indicators: Instantly see what's complete, in-progress, or pending
• Intelligent Task Breakdown: Automatically decompose complex features into actionable steps
• Multi-Agent Coordination: Tasks shared across multiple agent instances

🔍 Professional Web Research

TypeScript-native web research tools eliminate context switching between development and external resources.

• Integrated Research: Gather documentation without leaving the development workflow
• Content Processing: Smart extraction and summarization of technical content
• Project Memory: Maintain research context across sessions

🎵 Voice Feedback System

Long-running operations need progress updates. Audio feedback enables multitasking during complex automated tasks.

• TTS Integration: Stay informed about progress without watching the screen
• Multi-Voice Support: Assign different voices to different types of work
• Bluetooth Audio: Use wireless speakers for clear feedback

⚡ Local Model Optimization

Designed for local-first development with intelligent model switching.

• LM Studio Priority: Optimized for local inference workflows
• Ollama Secondary: Fallback for different model architectures
• Cloud Enhancement: Remote models as capability extension, not dependency

🖥️ Local Model Recommendations

Based on extensive testing with the FSS Enhanced FSS Link prototype:

⚡ High-Speed Development - qwen/qwen3-4b-2507

• Performance: 120+ tokens/second on dual RTX 3090 setup
• Context Window: 190k tokens with KV quantisation + Flash Attention
• Best for: Code completion, refactoring, documentation, analysis
• Experience: Comparable to Gemini Flash with enhanced system prompts

🧠 Complex Problem Solving - qwen/qwen3-30b-a3b-2507

• Performance: Slower but significantly more capable reasoning
• Context Window: 131k tokens with KV quantisation + Flash Attention
• Best for: Architecture decisions, complex debugging, system design
• When to use: Multi-step problems requiring deep analysis
