doca-argp

Use this skill for hands-on DOCA Arg Parser CLI work on a shipped sample or new DOCA-using app — adding / removing / renaming flags; wiring doca_argp_init → register params → doca_argp_start → doca_argp_destroy in order; picking a parameter type from the full public enum (DOCA_ARGP_TYPE_STRING, _INT, _BOOLEAN, _DEVICE, _DEVICE_REP, _DOUBLE — six values, not three); preserving the standard --device / --representor / --json (-j; real flag is --json, NOT --json-config) / --sdk-log-level surface; or debugging DOCA_ERROR_BAD_STATE / INVALID_VALUE / NOT_SUPPORTED / IO_FAILED from doca_argp_*. Trigger on implicit phrasings: "add a custom flag to a DOCA sample", "should I use getopt here", "BAD_STATE registering a new param", "my JSON config key is rejected", or "my sample's --json is ignored". Refuse and route elsewhere for variadic-flag / subcommand / shell-completion features, DOCA Core context, or DOCA Log internals.
