# What does this PR do? list-deps takes positional args OR things like --providers the issue with this, is that these args need to be optional since by nature, one or the other can be specified. add a check to list-deps that checks `if not args.providers and not args.config`. If this is true, help is printed and we exit. resolves #4075 ## Test Plan before: ``` ╰─ llama stack list-deps Traceback (most recent call last): File "/Users/charliedoern/projects/Documents/llama-stack/venv/bin/llama", line 10, in <module> sys.exit(main()) ^^^^^^ File "/Users/charliedoern/projects/Documents/llama-stack/src/llama_stack/cli/llama.py", line 52, in main parser.run(args) File "/Users/charliedoern/projects/Documents/llama-stack/src/llama_stack/cli/llama.py", line 43, in run args.func(args) File "/Users/charliedoern/projects/Documents/llama-stack/src/llama_stack/cli/stack/list_deps.py", line 51, in _run_stack_list_deps_command return run_stack_list_deps_command(args) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/charliedoern/projects/Documents/llama-stack/src/llama_stack/cli/stack/_list_deps.py", line 135, in run_stack_list_deps_command normal_deps, special_deps, external_provider_dependencies = get_provider_dependencies(build_config) ^^^^^^^^^^^^ UnboundLocalError: cannot access local variable 'build_config' where it is not associated with a value ``` after: ``` ╰─ llama stack list-deps usage: llama stack list-deps [-h] [--providers PROVIDERS] [--format {uv,deps-only}] [config | distro] list the dependencies for a llama stack distribution positional arguments: config | distro Path to config file to use or name of known distro (llama stack list for a list).
