🚀 What is Claude OS?

Claude OS is Claude Code's personal memory system - making AI the best coding assistant in the universe by remembering everything across sessions.

The Problem

You work with Claude Code on a feature, close the terminal, come back tomorrow... and Claude forgot everything. You explain the same architecture. You reference the same files. You repeat yourself constantly.

The Solution

Claude OS gives Claude persistent memory:

• 📝 Remembers decisions across all sessions
• 🔍 Searches past work automatically at session start
• 📚 Indexes your docs and makes them searchable
• 🧠 Learns patterns that improve over time
• 🤝 Shares with your team - one install, unlimited projects

Key Features

✅ Lightning-Fast Indexing - NEW! Tree-sitter hybrid indexing: 10,000 files in 30 seconds (vs 3-5 hours) ✅ One-Command Project Init - /claude-os-init and you're done ✅ Automatic Context Loading - Starts every session with relevant memories ✅ Session Management - Track work, save progress, resume later ✅ Documentation Ingestion - Auto-indexes your docs during setup ✅ Agent-OS Integration - Optional spec-driven development with 8 specialized agents ✅ Flexible AI - Choose local Ollama (free) or OpenAI API (paid) ✅ Team Sharing - ./install.sh for coworkers, works instantly ✅ 100% Local - Never leaves your machine, fully private ✅ Template System - Commands and skills shared via symlinks

⚡ NEW: Hybrid Indexing System

Claude OS v2.0 introduces lightning-fast tree-sitter based indexing!

The Problem with Traditional Indexing

Previous versions embedded EVERY file, which was painfully slow for large codebases:

• Pistn project (10,000 Ruby files): 3-5 hours to index
• Must complete before Claude can start working
• High resource usage, blocks productive coding

The Solution: Hybrid Two-Phase Indexing

Inspired by Aider's approach, Claude OS now uses:

Phase 1: Structural Index (30 seconds)

• ⚡ Parse files with tree-sitter (no LLM calls!)
• 📊 Extract symbols only (classes, functions, signatures)
• 🔗 Build dependency graph
• 🏆 PageRank importance scoring
• ✅ Ready to code immediately!

Phase 2: Semantic Index (optional, background)

• 🎯 Selective embedding (top 20% most important files)
• 📚 Full embedding for documentation
• 🔍 Deep semantic search when needed
• ⏰ Runs in background while you code

Performance Comparison

Feature	Before	After (Hybrid)
Pistn (10k files)	3-5 hours	30 seconds + 20 min optional
Files embedded	100,000+ chunks	~20,000 chunks (80% reduction)
Start coding	After full index	Immediately!
Resource usage	High Ollama load	Minimal CPU/memory
Query speed	Semantic search	Instant structural + semantic

⚡ Quick Start for Coworkers

Your coworker shared Claude OS with you? Here's the 3-minute setup:

Step 1: Clone and Install

# Clone the repository
git clone https://github.com/your-team/claude-os.git
cd claude-os

# Run the installer (handles everything)
./install.sh

The installer will:

• ✅ Set up Python environment
• ✅ Install all dependencies
• ✅ Configure MCP server
• ✅ Symlink commands and skills to ~/.claude/
• ✅ Optional: Install Agent-OS (8 agents by Builder Methods)
• ✅ Ask about AI provider (Ollama or OpenAI)
• ✅ Create start script

Step 2: Start Claude OS

./start.sh

This starts the MCP server at http://localhost:8051

Step 3: Initialize Your First Project

cd /path/to/your/project

In Claude Code, run:

/claude-os-init

Answer the questions (project name, tech stack, docs path, etc.) and you're done!

What you get:

• ✅ 4 knowledge bases created (memories, profile, index, docs)
• ✅ Documentation auto-indexed
• ✅ Codebase analyzed
• ✅ CLAUDE.md file with all context
• ✅ Ready to code with AI memory!

---

🎯 For First-Time Setup (Original Creator)

Prerequisites

Required:

• Python 3.11+ (python3 --version)
• Git (git --version)

Optional:

• Node.js 16+ (for React UI)

Installation

# 1. Clone the repository
git clone https://github.com/brobertsaz/claude-os.git
cd claude-os

# 2. Run the setup script
./setup.sh

# 3. Start all services
./start_all_services.sh

The setup script automatically installs:

• ✅ Ollama (if not present) + LLM models
• ✅ Redis (if not present) for caching/queues
• ✅ Python virtual environment
• ✅ All Python dependencies
• ✅ SQLite database
• ✅ Frontend dependencies (if Node.js present)

Visit http://localhost:5173 to use the web UI.

⚠️ IMPORTANT: Consolidate Your Files (Required for Team Sharing)

If you plan to share Claude OS with your team, you MUST run the consolidation script after setup:

./cli/claude-os-consolidate.sh

What this does:

• Moves all commands from ~/.claude/commands/ to templates/commands/
• Moves all skills from ~/.claude/skills/ to templates/skills/
• Creates symlinks so your local environment still works
• Enables team members to install Claude OS with ./install.sh

Without consolidation: Your coworkers' installations will be broken (symlinks will point to empty directories).

Then commit to git:

git add templates/ cli/ install.sh SHARING_GUIDE.md
git commit -m "Add packaging system for sharing"
git push

Now your team can clone and use ./install.sh!

🎨 The /claude-os-init Command

Initialize any project with Claude OS in under 2 minutes:

What It Does

cd /your/project

In Claude Code:

/claude-os-init

The command will:

1. Ask Questions Interactively:

   • Project name (auto-detects from folder)
   • Tech stack (Ruby on Rails, Python, Node.js, etc.)
   • Database (PostgreSQL, MySQL, etc.)
   • Development environment (Docker, Local, etc.)
   • Brief description
   • Documentation directory to ingest (optional)

2. Create Project in Claude OS:

   • Calls API to create project
   • Creates 4 knowledge bases automatically:
     • {project}-project_memories - Claude's memory
     • {project}-project_profile - Architecture & standards
     • {project}-project_index - Codebase index
     • {project}-knowledge_docs - Your documentation

3. Set Up Project Structure:

   your-project/
   ├── CLAUDE.md           # Auto-loaded every session!
   ├── .claude/            # Commands, skills, agents
   │   ├── ARCHITECTURE.md
   │   ├── CODING_STANDARDS.md
   │   └── DEVELOPMENT_PRACTICES.md
   └── .claude-os/         # Config and state (git-ignored)
       ├── config.json
       └── hooks.json
   

4. Ingest Documentation:

   • Scans your docs directory
   • Uploads all files to {project}-knowledge_docs
   • Creates vector embeddings for search

5. Analyze Codebase:

   • Runs initialize-project skill
   • Generates coding standards
   • Documents architecture
   • Indexes key files

6. Ready to Code:

   • Claude now knows your project
   • Memory persists across sessions
   • Context auto-loads on session start

---

🧠 How Claude OS Works

Session Workflow

Every Claude Code session automatically:

1. Checks for Active Session

   • Reads claude-os-state.json
   • Prompts: Continue working? Start something new?

2. Loads Context

   • Searches {project}-project_memories for recent work
   • Loads relevant patterns and decisions
   • Shows what it remembers

3. Works With Memory

   • Saves insights with /claude-os-remember
   • Searches memories with /claude-os-search
   • References past decisions automatically

4. Ends Session

   • Saves session summary
   • Updates memories
   • Tracks what was accomplished

Available Commands

All these work in any initialized project:

• /claude-os-init - Initialize new project
• /claude-os-search [query] - Search memories & docs
• /claude-os-remember [content] - Quick save to memories
• /claude-os-save [title] - Full-featured save with KB selection
• /claude-os-list - List all knowledge bases
• /claude-os-session [action] - Manage development sessions
• /claude-os-triggers - Manage trigger phrases

Available Skills

• initialize-project - Analyze codebase and generate standards
• remember-this - Auto-save when you say "remember this:"
• memory - Simple memory management

🤖 Agent-OS: Spec-Driven Development (Optional)

Created by Builder Methods (CasJam Media LLC) MIT Licensed • Optional Integration with Claude OS

Agent-OS adds structured workflows for planning and implementing features using 8 specialized agents.

Claude OS optionally integrates with Agent-OS during installation. Agent-OS is a separate open-source project created by Builder Methods, and we're grateful for their work in creating such powerful spec-driven development tools.

When to Use Agent-OS

Enable Agent-OS during /claude-os-init if you want:

• Structured feature planning with iterative requirements gathering
• Detailed specifications before coding
• Task breakdowns with clear implementation steps
• Verification workflows to ensure completeness

The 8 Agents

Specification Workflow:

1. spec-initializer - Initialize new spec directories
2. spec-shaper - Gather requirements through 1-3 questions at a time
3. spec-writer - Create detailed technical specifications
4. tasks-list-creator - Break specs into actionable tasks

Implementation Workflow:

5. implementer - Implement features following task list
6. implementation-verifier - Verify implementation completeness
7. spec-verifier - Verify specs and tasks consistency
8. product-planner - Create product documentation

Agent-OS Commands

Available when enabled:

• /new-spec - Initialize a new feature specification
• /create-spec - Full specification workflow (gather requirements → create spec → generate tasks)
• /plan-product - Create product mission, roadmap, and tech stack docs
• /implement-spec - Implement a specification following its tasks

How It Works

1. User: "/new-spec user-authentication"
   → Agent creates spec directory structure

2. User: "/create-spec"
   → spec-shaper asks 1-3 questions at a time
   → Gathers requirements iteratively
   → Identifies reusable code
   → Collects visual assets

3. Agent: spec-writer creates detailed specification
   → tasks-list-creator generates actionable tasks

4. User: "/implement-spec user-authentication"
   → implementer follows tasks step-by-step
   → implementation-verifier checks completeness

5. Result: Fully specified, implemented, and verified feature!

Agent-OS Project Structure

When enabled, your project gets:

your-project/
├── agent-os/
│   ├── config.yml          # Agent-OS configuration
│   ├── product/            # Product documentation
│   │   ├── mission.md      # Product mission
│   │   ├── roadmap.md      # Feature roadmap

│   └── standards/          # Coding standards (as skills)
└── .claude/agents/agent-os/  # 8 agents (symlinked)

AI Provider Options

Agent-OS requires AI for advanced features:

Option 1: Ollama (Local, Free)

• Requires 8GB+ RAM
• Fully private, no data leaves your machine
• Install: https://ollama.ai
• Then: ollama pull llama2

Option 2: OpenAI API (Cloud, Paid)

• Works on any machine
• ~$0.02 per request
• Requires API key (set during ./install.sh)

The installer will ask which you prefer!

Integration with Claude OS

Agent-OS agents deeply integrate with Claude OS:

• Search memories before creating specs (avoid reinventing)
• Save decisions to project_memories during planning
• Reference patterns from previous work
• Build knowledge that improves over time

This is the complete AI development system!

---

🤝 Team Collaboration

Sharing Claude OS

Step 1: Package for sharing

cd /path/to/claude-os
./cli/claude-os-consolidate.sh  # Move files to templates/
git add templates/ cli/ install.sh
git commit -m "Ready for team sharing"
git push

Step 2: Share repo URL with team

Send teammates:

• Repo URL
• Link to SHARING_GUIDE.md in the repo

Step 3: They install (3 minutes)

git clone <your-repo-url>
cd claude-os
./install.sh
./start.sh

Done! They can now use /claude-os-init on any project.

Per-Project Setup

Each team member:

1. Runs /claude-os-init in their project
2. Gets their own knowledge bases
3. CLAUDE.md is committed to git (shared)
4. .claude-os/ state is git-ignored (personal)

Result: Team shares context via CLAUDE.md, but each person has their own AI memory.
