Orchestrate Sypha agents from your terminal for a keyboard-first, high-velocity development workflow.

The Sypha CLI lets you command AI agents directly from your terminal — plan, debug, and ship code without leaving the command line. It uses the same engine as our IDE extensions for a consistent agentic workflow across your stack.

Installation

npm install -g @sypha-ai/cli

conda install -c sypha_ai sypha-cli

Navigate to your workspace and run sypha to begin:

sypha                 # Start an interactive session
sypha --agent plan    # Start in a specific agent
sypha --continue      # Resume the most recent conversation here

Updating

npm update -g @sypha-ai/cli

Or just run /update inside the CLI.

Strategic capabilities

Terminal-first development

Plan and execute complex changes directly in your shell.

Model-agnostic

Switch between hundreds of models across ~40 providers (Claude, GPT, Gemini, Llama, local, and more) with no lock-in.

Specialised agents

Pick between Code, Plan, Debug, Orchestrator, and Ask agents, or define your own.

Automation

Authorise Sypha to write and run shell scripts for repetitive tasks.

Extensible

Add domain expertise with Sypha Skills.

Enterprise Access Control

On Teams, admins govern which tools need approval, which providers are allowed, and terminal/browser/MCP access — enforced live in every member's CLI within ~10s.
