Function run_staged 

pub async fn run_staged(
    print_only: bool,
    no_ai: bool,
    model: Option<String>,
    beta_header: Option<(String, String)>,
    context_dir: Option<&Path>,
    repo_path: Option<&Path>,
) -> Result<StagedOutcome>

Public entry point for the staged-commit command.

Mirrors crate::cli::git::run_twiddle’s shape so the MCP server can wrap it the same way: resolve the repo root (the injected path, or the CWD as the default), run AI preflight, build the client, and delegate to the test-injectable inner [run_staged_with_client].

no_ai skips AI entirely (no credential preflight, no client, no network call) and returns a deterministic type(scope): skeleton instead — see [run_staged_no_ai].
