Command-line tool

Eidos CLI

Create, inspect, and edit Eidos Files, or launch the editor in your local browser. Revision checks and typed validation give automation and agents a safe boundary.

  1. 01 · Install

    Install Eidos CLI

    macOS and Linux 

    curl -fsSL https://download.eidos.space/cli/install.sh | sh

    Windows PowerShell 

    irm https://download.eidos.space/cli/install.ps1 | iex

  2. 02 · Local Web Editor

    Create a file and open it in your browser

    The commands work on macOS, Linux, and Windows. The editor listens only on localhost; files stay local and no account is required.

    Run after installing the CLI 

    eidos create tracker.eidos
eidos serve tracker.eidos --open

  3. 03 · Agent workflow

    Set up the Eidos Skill

    Write the CLI-bundled Eidos Skill to the current project or your user profile so coding agents with Agent Skills support can read context, apply changes, and validate results.

    Current project or global · no Node.js or npx 

    eidos skills init

    The Skill ships with the CLI. Start a new task after setup so your agent loads it.

  4. 04 · First task

    Begin with a read-only check

    Have the agent confirm the file and revision before making changes. 

    Use the Eidos skill to inspect ./tracker.eidos.
Show context first and do not mutate yet.
