# NEXUS Documentation
**Network of EXperts, Unified in Strategy** — a tool-agnostic framework for multi-model agentic orchestration.
## What NEXUS does
NEXUS sits between your AI CLI tools and your local/cloud models. It:
1. **Routes tasks** — cloud for deep reasoning, local Ollama for structured micro-tasks
2. **Manages personas** — specialized agent definitions for different engineering roles
3. **Delegates locally** — via an MCP server that routes to Ollama models on your machine
4. **Configures everything** — through symlinks so your AI tools read from NEXUS without knowing it
5. **Observes your stack** — tracks usage, costs, and routing decisions across all tools (v0.2.0)
## Quick navigation
## Prerequisites
**Required:** Bash, one or more AI CLI tools (Claude Code, Gemini CLI, or Kiro CLI)
**Optional:** Node.js (for the MCP server), Ollama (for local LLM delegation)
**Platform support:** Linux and macOS. Windows is tracked in [#18](https://github.com/canoo/agent-nexus/issues/18).
> No Go toolchain needed — the `nexus` binary is distributed as a pre-built download.
