# OMNI Context OS > OMNI is the Context Operating System for Autonomous AI Agents. It intercepts noisy terminal outputs, distills them, and feeds pure signal back to the AI. ## Tool Summary OMNI is a CLI tool and MCP (Model Context Protocol) server designed to dramatically improve token efficiency (by up to 90%) and reduce hallucinations for AI agents such as Claude Code, Cursor, and Copilot. It operates as a high-performance semantic filter between the terminal and LLMs. ### Key Features - **Token Efficiency & Massive ROI**: Mutes noisy build outputs, test runners, and infrastructure logs to only show relevant failures and summaries. - **Zero Hallucinations & High Fidelity**: Retains essential context by permanently pinning critical files (like `AGENTS.md`) and tracking dependency graph impacts. - **RewindStore**: 100% context safety. The full raw logs are always saved locally and can be accessed if needed. - **Omni Learn**: Uses machine learning to detect noisy patterns and generate semantic TOML filters for your tech stack. - **Autonomous Loops**: Uses Maker-Checker verification and enforces predictive token constraints via `OMNI_LOOP_BUDGET`. ### Installation Terminal prompt: $ brew install fajarhide/tap/omni Universal Installer: $ curl -fsSL omni.weekndlabs.com/install | bash Windows: $ irm omni.weekndlabs.com/install.ps1 | iex ### Usage Pipe any command to omni to distil the output: $ cargo check | omni
