Before installing ARIA, ensure you have:

Operating System

ARIA is pure YAML + Markdown read by Claude Code at runtime -- there is no compilation, no native binaries, and no OS-specific dependencies. It runs wherever Claude Code runs.

OS Status Notes
macOS Fully supported bash and curl pre-installed
Linux Fully supported bash and curl pre-installed on most distros
Windows (WSL) Fully supported Same as Linux -- run everything inside WSL
Windows (native) Supported Use Git Bash for the installer. Clone-and-install method recommended over pipe-to-shell.

The installer (install.sh) requires a bash-compatible shell -- bash, zsh, or Git Bash. PowerShell and CMD are not supported for installation, but once installed ARIA runs entirely through Claude Code which works on any OS.

Required

  • Claude Code -- ARIA runs as slash commands inside Claude Code
  • A supported platform -- either Plane (self-hosted or cloud) or Linear with at least one team/project
  • Platform API key -- see your platform's API settings to generate one
  • Node.js 18+ -- required to run MCP servers via npx (Linear only; Plane uses Claude Code's built-in MCP)
  • Git -- for optional Git/GitHub integration features
  • GitHub CLI (gh) -- for PR creation and review automation

Platform Permissions

Your API key needs access to:

  • Read and write work items, epics, sprints, milestones, and documents
  • Read team/project and user information
  • Manage labels, comments, and properties
