### Please complete the following tasks - [x] I have searched the [discussions](https://github.com/clap-rs/clap/discussions) - [x] I have searched the [open](https://github.com/clap-rs/clap/issues) and [rejected](https://github.com/clap-rs/clap/issues?q=is%3Aissue+label%3AS-wont-fix+is%3Aclosed) issues ### Rust Version rustc 1.91.1 (ed61e7d7e 2025-11-07) ### Clap Version v4.5.56 ### Minimal reproducible code cli named `min` ```rust use std::path::PathBuf; use clap::{Parser, command}; #[derive(Parser, Debug, Clone)] #[command(ignore_errors = true)] pub struct DirConfig { #[arg(long, global = true, value_hint = clap::ValueHint::DirPath)] pub root_dir: Option, #[arg(long, global = true, value_hint = clap::ValueHint::DirPath)] pub src_dir: Option, } #[derive(Parser, Debug)] #[command(name = "min")] #[command(version, about, long_about = None)] pub struct Args { #[command(flatten)] pub dir_config: DirConfig, #[command(subcommand)] pub command: Commands, } #[derive(Parser, Debug)] pub enum Commands { First(first::Args), } mod first { use clap::Parser; #[derive(Parser, Debug)] #[command(name = "first")] #[command(version, about, long_about = None)] pub struct Args { #[command(subcommand)] pub command: Commands, } #[derive(Parser, Debug)] pub enum Commands { Nested(nested::Args), } mod nested { use clap::Parser; #[derive(Parser, Debug)] #[command(name = "nested")] #[command(version, about, long_about = None)] pub struct Args { } } } fn main() { Args::parse(); } ``` ### Steps to reproduce the bug with the above code `min first --help` ### Actual Behaviour ```zsh error: a subcommand is required but one was not provided Usage: min [OPTIONS] For more information, try '--help'. ``` ### Expected Behaviour if i comment out the flattened global args ```rust pub struct Args { // #[command(flatten)] // pub dir_config: DirConfig, ``` Works ```zsh min first --help Usage: min first Commands: nested help Print this message or the help of the given subcommand(s) Options: -h, --help Print help -V, --version Print version ``` ### Additional Context _No response_ ### Debug Output ```zsh [clap_builder::builder::command]Command::_do_parse [clap_builder::builder::command]Command::_build: name="min" [clap_builder::builder::command]Command::_propagate:min [clap_builder::builder::command]Command::_check_help_and_version:min expand_help_tree=false [clap_builder::builder::command]Command::long_help_exists [clap_builder::builder::command]Command::_check_help_and_version: Building default --help [clap_builder::builder::command]Command::_check_help_and_version: Building default --version [clap_builder::builder::command]Command::_check_help_and_version: Building help subcommand [clap_builder::builder::command]Command::_propagate_global_args:min [clap_builder::builder::command]Command::_propagate pushing "root_dir" to first [clap_builder::builder::command]Command::_propagate pushing "src_dir" to first [clap_builder::builder::debug_asserts]Command::_debug_asserts [clap_builder::builder::debug_asserts]Arg::_debug_asserts:root_dir [clap_builder::builder::debug_asserts]Arg::_debug_asserts:src_dir [clap_builder::builder::debug_asserts]Arg::_debug_asserts:help [clap_builder::builder::debug_asserts]Arg::_debug_asserts:version [clap_builder::builder::debug_asserts]Command::_verify_positionals [clap_builder::parser::parser]Parser::get_matches_with [clap_builder::parser::parser]Parser::parse [clap_builder::parser::parser]Parser::get_matches_with: Begin parsing '"first"' [clap_builder::parser::parser]Parser::possible_subcommand: arg=Ok("first") [clap_builder::parser::parser]Parser::get_matches_with: sc=Some("first") [clap_builder::parser::parser]Parser::parse_subcommand [ clap_builder::output::usage]Usage::get_required_usage_from: incls=[], matcher=false, incl_last=true [ clap_builder::output::usage]Usage::get_required_usage_from: unrolled_reqs=[] [ clap_builder::output::usage]Usage::get_required_usage_from: ret_val=[] [clap_builder::builder::command]Command::_build_subcommand Setting bin_name of first to "min first" [clap_builder::builder::command]Command::_build_subcommand Setting display_name of first to "min-first" [clap_builder::builder::command]Command::_build: name="first" [clap_builder::builder::command]Command::_propagate:first [clap_builder::builder::command]Command::_check_help_and_version:first expand_help_tree=false [clap_builder::builder::command]Command::long_help_exists [clap_builder::builder::command]Command::_check_help_and_version: Building default --help [clap_builder::builder::command]Command::_check_help_and_version: Building default --version [clap_builder::builder::command]Command::_check_help_and_version: Building help subcommand [clap_builder::builder::command]Command::_propagate_global_args:first [clap_builder::builder::command]Command::_propagate pushing "root_dir" to nested [clap_builder::builder::command]Command::_propagate pushing "src_dir" to nested [clap_builder::builder::debug_asserts]Command::_debug_asserts [clap_builder::builder::debug_asserts]Arg::_debug_asserts:root_dir [clap_builder::builder::debug_asserts]Arg::_debug_asserts:src_dir [clap_builder::builder::debug_asserts]Arg::_debug_asserts:help [clap_builder::builder::debug_asserts]Arg::_debug_asserts:version [clap_builder::builder::debug_asserts]Command::_verify_positionals [clap_builder::parser::parser]Parser::parse_subcommand: About to parse sc=first [clap_builder::parser::parser]Parser::get_matches_with [clap_builder::parser::parser]Parser::parse [clap_builder::parser::parser]Parser::get_matches_with: Begin parsing '"--help"' [clap_builder::parser::parser]Parser::possible_subcommand: arg=Ok("--help") [clap_builder::parser::parser]Parser::get_matches_with: sc=None [clap_builder::parser::parser]Parser::parse_long_arg [clap_builder::parser::parser]Parser::parse_long_arg: Does it contain '='...
