# Welcome
### 🚀 What is Orbitron?
**Orbitron** is an **intelligent terminal-based AI assistant** for cloud engineers.\
It is built to **maximize productivity in DevOps and infrastructure operations** across various cloud platforms, including AWS, GCP, and Azure.
Without needing to memorize or manually execute complex CLI commands, Orbitron **understands natural language instructions**\
and automates infrastructure tasks using AI. This allows engineers to experience **a more intuitive and efficient workflow**.
Orbitron is not just a command execution tool; through its **context-aware AI engine**, it understands user intent and context\
and performs a variety of tasks such as **cloud resource management, deployment automation, system diagnostics, and policy validation**.
As a result, Orbitron serves as a **`next-generation CLI companion that seamlessly integrates AI into a developer's terminal environment`**,\
lowering the barrier to complex cloud engineering and improving operational efficiency across teams.

### 🌟 Key Features
#### 1. AI-Powered Cloud Engineering
Orbitron enables **direct AI collaboration within your terminal** for DevOps and infrastructure operations.
Instead of memorizing complex commands, simply communicate in natural language, and the AI will handle **instance provisioning, resource inspection, permission verification, deployment automation**, and more. This allows engineers to break free from repetitive, error-prone tasks and focus on core design and operations.
#### 2. Multi-Cloud Support
Orbitron supports all major cloud platforms including **AWS, GCP, and Azure**.
Manage multiple cloud resources from a single unified interface without configuring separate CLI environments for each platform. This enables organizations to minimize cloud vendor lock-in and **maximize operational efficiency in multi-cloud strategies**.
#### 3. Multi-Model AI Backend
Orbitron integrates with a variety of large language models (LLMs).\
Users can select the most suitable model for their needs.
Supported Models:
* **Google Vertex AI**
* **AWS Bedrock**
* **Gemini**
* **OpenAI**
* **Anthropic**
* **Custom Model**
This flexible backend architecture provides a **scalable AI infrastructure** that avoids vendor lock-in.
#### 4. MCP (Model Context Protocol) Integration
Orbitron **dynamically connects external tools and services** through standardized protocols.
Access various resources like databases, APIs, and file systems via MCP servers, enabling the AI to leverage real-time information for task execution. Tool caching and status monitoring ensure stable and efficient scaling.
#### 5. Interactive Bash Mode
Use the `!` prefix to **instantly execute terminal commands** and cancel running tasks with the ESC key.
Asynchronous execution with real-time output display allows seamless switching between AI conversations and shell commands. System messages and bash history are filtered from AI context to maintain a clean conversation environment.
#### 6. Shell Hooks System
Automatically execute **custom shell commands before and after AI tool execution**.
Validate conditions or block execution with preToolUse hooks, and perform post-processing with postMessageUse hooks. Set hooks for specific tools or all tools, making it ideal for team workflow automation and policy enforcement.
#### 7. Automatic Conversation Compaction & Context Preservation
For extended sessions, Orbitron **automatically summarizes conversations at 85% context window capacity**, retaining only essential information. Streaming-based summarization and intelligent message management ensure both **memory efficiency and response speed**, enabling continuous work without context loss over time.
#### 8. Intuitive Terminal UI (TUI)
Orbitron provides a **visually clear and responsive interface** even in text-based environments.
Command execution, result display, log navigation, and session management flow naturally within the terminal, supporting modern UX features like file drag-and-drop, image preview, and keyboard shortcuts. With **75x faster TUI startup** (3-5 seconds → 0.04 seconds), you can begin work immediately.
#### 9. Session Export & Permission Management
Export conversation history in various formats including **TXT, MD, and JSON** for easy team sharing and documentation. Session-level permission management controls access to sensitive operations, providing a secure environment for collaboration.
#### 10. Automatic Update System
**Automatically checks for the latest version every 6 hours** and handles updates seamlessly across platforms.
Compliant with XDG standards, with instant updates available via the `/update` command in TUI. Critical security updates provide immediate notifications to maintain system stability.
