#!/usr/bin/env bash
# Bootstrap for the copilot-custom-logging plugin hooks (macOS/Linux).
#
# Copilot runs hook commands with the user's working directory, not the
# plugin directory, so a plain relative path to the dispatcher won't resolve.
# This bootstrap reads the event payload, locates otel_dispatch.py inside the
# installed plugin directory, and runs it. hooks.json embeds a copy of this
# script (it is the tiny entry point); all real logic lives in
# otel_dispatch.py.
#
# It always exits 0 (fail-open): a PreToolUse command hook is fail-closed on a
# non-zero exit, so telemetry problems must never block the user's tools.
