OpenSpec Install Skill

Install the OpenSpec CLI so that openspec is available globally. This skill covers only installing the CLI; it does not run openspec init. For project initialization after install, use openspec-initial.

When to Use

• First-time OpenSpec setup ("install OpenSpec", "get started with OpenSpec").
• User reports "openspec: command not found".
• Upgrading to the latest version.
• CI or scripts that need the CLI pre-installed.

Prerequisites

• Node.js 20.19.0 or higher — Check with node --version. If not installed, guide the user to install Node.js first (e.g. via nvm, fnm, or official installer).

Workflow

1. Check if already installed
   • Run openspec --version. If it succeeds, the CLI is already installed; suggest openspec-initial for project setup or upgrading via npm install -g @fission-ai/openspec@latest.
