In `@crates/wisp-bin/src/main.rs`:
- Around line 391-415: Reject a parsed --line value of 0 before calling tmux by
validating the Option<usize> in run_statusline_group: in the
StatuslineSubcommand::Install(args) and ::Uninstall(args) branches check if
args.line == Some(0) and return an Err with a clear message (e.g. "statusline
line must be >= 1") instead of proceeding; this prevents invalid 0 rows from
being dispatched to install_statusline or uninstall_statusline.
- Around line 346-349: The Statusline branch currently loads config before
checking mutually-exclusive CLI flags, so move or duplicate the flag validation
to run before load_runtime_config in the Command::Statusline(statusline) arm:
perform the same mutual-exclusion check that run_statusline_group() enforces
(e.g. extract or call a helper like validate_statusline_flags(statusline) or
check_conflicting_statusline_flags(statusline)) and return an appropriate CLI
error if flags conflict, then call load_runtime_config() and
run_statusline_group(&config, statusline) only after validation succeeds.
In `@crates/wisp-bin/tests/smoke.rs`:
- Around line 48-61: The new smoke test only exercises the "statusline" command
but not the backwards-compatibility rewrite in parse_cli() for the "status-line"
alias, so add a parallel test that runs the binary with args ["status-line",
"--help"] (similar to the existing statusline_help_lists_nested_subcommands
test) and asserts the process succeeds and its stdout contains the same key
substrings ("Usage:", "install", "render", "uninstall"); locate the test
function statusline_help_lists_nested_subcommands and duplicate its logic in a
new test (e.g., status_line_help_lists_nested_subcommands) to ensure
parse_cli()'s rewrite branch is covered.

In `@crates/wisp-bin/src/main.rs`:
- Around line 346-349: The CLI currently validates only render flags and still
calls load_runtime_config() for Command::Statusline before rejecting invalid
--line values, which lets a broken config mask CLI errors; update the
Command::Statusline handling so validate_statusline_flags(&statusline) (or a
more specific pre-config validation for install/uninstall subcommands) runs and
returns an error for invalid --line values before any call to
load_runtime_config(), and apply the same change to the other statusline
handling branch (the run_statusline_group(...) calls around the other block) so
install/uninstall validation is performed and exits early on invalid line
numbers.
- Around line 263-299: parse_cli() currently reads env::args() directly which
prevents unit testing the hidden "ui" branch and the status-line rewrite;
extract the logic into a new function (e.g., parse_cli_args(args: &[&str]) ->
Result<ParsedCli, argh::EarlyExit>) that performs the same behavior (handle the
"ui" help/error path with ui_help_early_exit and UiMode::from_arg_value, rewrite
"status-line" to "statusline", default to "help", and call Cli::from_args to
produce ParsedCli::Public), then make parse_cli() a thin wrapper that collects
env::args() and calls parse_cli_args; update callers/tests to call
parse_cli_args directly to unit-test the ui branch, ui parse errors, and the
status-line rewrite without spawning the binary.

🧹 Nitpick | 🔵 Trivial
Consider pinning the toolchain channel to match the declared MSRV.
Using channel = "stable" allows the toolchain to drift ahead of the declared rust-version = "1.90" in Cargo.toml. This could lead to developers using features not available in 1.90 without CI catching the regression (since CI also uses a specific version). Consider either:
- Pinning the channel to
"1.90"here for consistency, or - Relying solely on CI's explicit
