Eidos CLI

The CLI is a standalone structured machine interface—not another way to install Desktop. It updates .eidos files safely with revisions, exact matching, typed mutations, and validation.

  1. 01 · Machine interface

    Install Eidos CLI

    macOS and Linux 

    curl --proto '=https' --tlsv1.2 -LsSf https://download.eidos.space/cli/install.sh | sh

    Windows PowerShell

  2. 02 · Agent workflow

    Add the Eidos Skill to Codex

    The CLI owns the typed transaction boundary. The Skill teaches Codex to use context, apply, validation, and Graft. It installs from the same public tag as the stable CLI—not the moving development branch.

    Codex · global · Node.js 18+ 

    npx skills add \
  https://github.com/mayneyao/eidos/tree/cli-v0.34.0/skills/eidos \
  --skill eidos -g -a codex -y

    The Skill is pinned to CLI 0.34.0. Start a new Codex task after installation.

  3. 03 · First task

    Begin with a read-only check

    Have the agent load compact context and confirm the file and revision before deciding whether to mutate anything. 

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

Stable · 0.34.0. The installer resolves the stable release and verifies the download against its SHA256SUMS before replacing the binary.
