142| Term | Meaning |\n\
143|------|---------|\n\
144| **Allowed standalone flags** | Flags that take no value (`--verbose`, `-v`). Listed on flat commands. |\n\
145| **Flags** | Same as standalone flags, but in the shorter format used within subcommand entries. |\n\
146| **Allowed valued flags** | Flags that require a value (`--output file`, `-j 4`). |\n\
147| **Valued** | Same as valued flags, in shorter format within subcommand entries. |\n\
148| **Bare invocation allowed** | The command can be run with no arguments at all. |\n\
149| **Subcommands** | Named subcommands that are allowed (e.g. `git log`, `cargo test`). |\n\
150| **Positional arguments only** | No specific flags are listed; only positional arguments are accepted. |\n\
151| **(requires --flag)** | A guarded subcommand that is only allowed when a specific flag is present (e.g. `cargo fmt` requires `--check`). |\n\
