          The Experimental AI Microkernel

FyodorOS is a simulated operating system designed from the ground up for Autonomous AI Agents. Unlike traditional OSs designed for humans (GUI/CLI) or servers (API), FyodorOS exposes the entire system state as a Document Object Model (DOM), allowing Agents to "perceive" and interact with the kernel natively.

🚀 Vision

We believe that for AI Agents to be truly useful and safe, they need an environment built for them. FyodorOS provides:

• Structured Observation: The OS state (Filesystem, Processes, Users) is a queryable DOM tree.
• Cognitive Loop: Built-in ReAct (Reasoning + Acting) loop at the kernel level.
• Safety Sandbox: A strict, rule-based verification layer that constraints Agent actions before execution.
• Agent-Native Apps: Standard tools (browser, explorer, calc) that return structured JSON/DOM instead of plain text, minimizing token usage and parsing errors.
• Cloud Integration (v0.5.0): Native Docker and Kubernetes support.

📝 What's New

[0.6.0] - Verified System Integrity (Test Sweep Phase 2.3)

FyodorOS v0.6.0 focuses on system integrity and reliability:

• Verified Core Subsystems: Successfully passed extensive adversarial tests for Service Manager, Kernel Boot, Sandbox, and Plugin Lifecycle.
• Boot Determinism: Confirmed clean, deterministic startup and shutdown cycles.
• Teardown Correctness: Implemented proper LIFO (Last-In-First-Out) service shutdown to prevent ghost processes.
• Advanced Service Manager: New ServiceManager architecture supports:
  • Dependency Graphs: Services start and stop in topologically sorted order.
  • 3-Phase Shutdown: Warning -> Graceful -> Force protocol with timeouts.
  • Robustness: Non-blocking shutdown using threaded timeout enforcement.
• Sandbox Security Patch: Fixed a vulnerability where fallback to Python implementation allowed path traversal. Now enforces strict sandbox rooting.

[0.5.1] - Performance & Security Hardening

FyodorOS v0.5.1 focuses on stability, security, and speed:

• Startup Speed: 10x faster startup via lazy loading of heavy cloud dependencies.
• Security: Fixed critical shell login bypass and strengthened sandbox isolation.
• Stability: Robust C++ sandbox execution and deadlock prevention.

[0.5.0] - Cloud Integration

FyodorOS v0.5.0 introduces major cloud capabilities:

• Docker Integration: Agent control of containers via sys_docker_* syscalls.
• Kubernetes Integration: Deployment management and pod inspection.

✨ Key Features

🧠 Kernel-Level Agent

The OS integrates an LLM-powered agent directly into the shell.

• Command: agent "Research the latest news on AI"
• Mechanism: The agent perceives the system via SystemDOM, creates a To-Do list, and executes actions in a sandboxed loop.

🌐 Agent Browser (Playwright Integration)

FyodorOS includes a specialized browser for agents.

• DOM Tree Output: Returns a simplified, semantic JSON representation of web pages.
• Interaction: Agents can click and type using element IDs directly.
• Efficiency: Strips unnecessary noise (CSS/Scripts) to save context window.

🛡️ Safety Sandbox (Verified v0.6.0)

Every action taken by the Agent is intercepted by the C++ reinforced AgentSandbox.

• Virtual Filesystem: The agent is jailed in ~/.fyodor/sandbox. All paths are virtualized.
• Path Traversal Protection: C++ layer prevents escaping the sandbox (e.g., ../../etc/passwd). Verified Python fallback ensures security even without C++ extensions.
• Process Isolation: Commands run with cleared environments and restricted paths.
• App Whitelisting: Only authorized "Agent Apps" can be executed.

🧪 Test Coverage (v0.6.0)

We maintain rigorous test suites to ensure system invariants hold under pressure.

• Service Manager: Boot correctness, reverse teardown, failure resilience.
• Kernel: Deterministic boot, double-boot isolation, controlled shutdown.
• Sandbox: File resolution integrity, IOError containment, leakage prevention.
• Plugins: Lifecycle management (init/exec/teardown), fault tolerance.

Tests are run using pytest:

pytest tests/phase2_3/

🔌 Plugins (New in v0.3.0)

FyodorOS supports a powerful plugin system.

• Github Integration: github - List repos, create issues, view PRs.
• Slack Notifier: slack_notifier - Send notifications to Slack.
• Usage Dashboard: usage_dashboard - Background system monitoring. View with fyodor dashboard.
• Team Collaboration: team_collaboration - RBAC system extending UserManager.

Managing Plugins

fyodor plugin list
fyodor plugin activate github
fyodor plugin settings github token YOUR_TOKEN
fyodor plugin deactivate github

Developing Plugins (Polyglot Support)

FyodorOS supports Python, C++, and Node.js plugins.

Create a new plugin:

fyodor plugin create my_plugin --lang cpp

Build a plugin:

fyodor plugin build my_plugin

Install from Git:

fyodor plugin install https://github.com/user/repo

📦 Installation & Usage

1. Clone the Repository

   git clone https://github.com/Kiy-K/FyodorOS.git
   cd fyodoros
   

2. Install Package You can install FyodorOS as a Python package.

   Via pip (Recommended):

   pip install .
   playwright install chromium
   

   Via Conda:

   conda env create -f environment.yml
   conda activate fyodoros
   playwright install chromium
   

3. Launch the OS

   Option A: Using the CLI (if installed)

   # 1. Setup (Configure API Keys)
   fyodor setup
   
   # 2. Start (Auto-login as Guest)
   fyodor start
   
   # 3. Interactive Login
   fyodor login
   
   # 4. Login as specific user (e.g. root)
   fyodor login --user root
   
   # 5. Create a new user
   fyodor user developer secret123
   
   # 6. Open Launcher Menu (TUI)
   fyodor tui
   

   Option B: Using Convenience Scripts

   • Windows: Double-click run.bat
   • Linux/Mac: Run ./run.sh

4. Interact Inside the FyodorOS Shell:

   # Run a standard command
   guest@fyodoros:/> ls
   
   # Task the Agent
   guest@fyodoros:/> agent "Create a file named hello.txt in my home folder"
   
   # Manual Creation
   guest@fyodoros:/> create notes.txt "Meeting at 5pm"
   
   # Launch App Manually
   guest@fyodoros:/> navigate browser
   

💡 Use Cases

1. Web Research & Summary

Scenario: You want the agent to look up information and save it. Command:

agent "Go to https://example.com, read the main heading, and save it to /home/guest/summary.txt"

Agent Process:

1. Calls run_process("browser", ["navigate", "https://example.com"]).
2. Parses the returned DOM tree to find the <h1> tag.
3. Calls write_file("/home/guest/summary.txt", ...) to save the data.

2. System Management

Scenario: You want to add a new user securely. Command:

agent "Create a new user named 'developer' with password 'secure123'"

Agent Process:

1. Checks if user exists using run_process("user", ["list"]).
2. Calls run_process("user", ["add", "developer", "secure123"]).
3. Verifies the addition.

3. File Organization

Scenario: Organize a messy directory. Command:

agent "Move all .txt files from /home/guest to /home/guest/documents"

Agent Process:

1. Calls list_dir("/home/guest").
2. Identifies .txt files.
3. Calls run_process("explorer", ["move", ...]) for each file.
