# Ork Meter installer for Windows (PowerShell 5.1 or later).
#
#   irm https://orkmeter.com/install.ps1 | iex
#
# Installs the Ork Meter plugin for each agent it finds on your PATH:
#   Claude Code (2.1.280 or later)   via `claude plugin ...`
#   Codex (the Codex CLI)            via `codex plugin ...`, then setup,
#                                    which needs Python 3.11, 3.12 or 3.13
#
# This script downloads nothing itself. Claude Code and Codex fetch the
# plugins, and every release they fetch is pinned by SHA-256: the Claude
# marketplace file names the plugin zip's digest, and the Codex installer's
# release.json names the wheel's. Run it again at any time to update in place.
# It needs no administrator rights and writes only through the agents' own
# plugin commands. Source and support: https://orkmeter.com/install
