Usage: test-chat-template [OPTIONS] PATH_TO_TEMPLATE
Options:
  -h, --help               Show this help message and exit.
  --with-tools             Add a tool and a tool call to the default JSON input
  --json <path>            Path to the JSON input file.
  --stop-on-first-fail     Stop testing on the first failure (default: false).
  --no-common              Use direct Jinja engine instead of common chat templates (default: use common).
  --output <path>          Path to output results (only for single template runs).
If PATH_TO_TEMPLATE is a file, runs that single template.
If PATH_TO_TEMPLATE is a directory, runs all .jinja files in that directory.
If PATH_TO_TEMPLATE is omitted, runs automated tests (default CI mode).
