# omoa — Toggle oh-my-openagent plugin for OpenCode
# =============================================================================
#
# PURPOSE:
#   This script provides a simple way to enable or disable the oh-my-openagent
#   (omoa) plugin for OpenCode. oh-my-openagent is a third-party plugin that
#   adds multi-model orchestration, LSP tools, and other advanced features to
#   OpenCode. However, it can interfere with normal OpenCode operation, so it
#   needs to be toggled on/off as needed.
#
# CONTEXT:
#   - oh-my-openagent modifies the OpenCode config file (opencode.json) when
#     enabled, creating a backup first
#   - When disabled, the original config is restored from backup
#   - The OpenCode server and Telegram bot need to be restarted after toggling
#
# USAGE:
#   ./omoa.sh          — Show current status
#   ./omoa.sh on       — Enable oh-my-openagent
#   ./omoa.sh off      — Disable oh-my-openagent (restore from backup)
#   ./omoa.sh status   — Show current status (same as no args)
#
# TELEGRAM INTEGRATION:
#   This script is registered as an OpenCode skill in opencode.json under the
#   "skills" section. When the OpenCode Telegram bot is running, users can
#   invoke this via /commands → omoa_toggle in Telegram.
#
# UPSTREAM REPO:
#   https://git.hibbhome.com/Hibbhome/opencode-omoa-toggle
#
# KNOWN ISSUES (as of 2026-05-03):
#   - The omoa install command is fragile and may fail silently
#   - The --no-tui flag requires all options to be specified manually
#   - The script does not verify success before restarting services
#   - The enable/disable logic could be cleaner
#   - Needs overhaul to handle edge cases better

  # oh-my-openagent installer options:
  #   --no-tui     — Run non-interactively (required for scripts)
  #   --skip-auth  — Skip authentication setup (we handle auth separately)
  #   --claude=no  — Disable Claude provider (we use our own proxy)
  #   --gemini=no  — Disable Gemini provider
  #   --copilot=no — Disable GitHub Copilot provider
  #
  # Note: These options are required because --no-tui mode demands all
  # options be specified. The values here match our current setup where
  # we use custom providers (Zen, Mimo, etc.) instead of the built-in ones.
