#!/usr/bin/env bash
# Desktop-notification hook: posts a notification describing the event that
# fired, falling back to a message on the controlling terminal when no
# notifier is present.
#
# Env vars read (set by coyote when the hook fires):
#   COYOTE_EVENT        dotted event name, e.g. turn.completed
#   COYOTE_AGENT_NAME   agent name, when the event carries one
#   COYOTE_TOOL_NAME    tool name, when the event carries one
#
# Wire it up under `hooks:` in your config.yaml:
#   hooks:
#     turn.completed:
#       - name: notify
#         command: ./hooks/notify.sh
#
# A relative command path like ./hooks/notify.sh resolves against the coyote
# config directory for global hooks, so this works with the default hooks dir.
#
# See https://github.com/Dark-Alex-17/coyote/wiki/Hooks for the full list of
# events and env vars. Hooks are fire-and-forget: this script never fails
# loudly, and coyote ignores its exit code either way.
