/**

* CLI exit helpers for subcommand handlers.

*

* Consolidates the 4-5 line "print + lint-suppress + exit" block that was

* copy-pasted ~60 times across `claude mcp *` / `claude plugin *` handlers.

* The `: never` return type lets TypeScript narrow control flow at call sites

* without a trailing `return`.

*/

/* eslint-disable custom-rules/no-process-exit -- centralized CLI exit point */

// `return undefined as never` (not a post-exit throw) — tests spy on

// process.exit and let it return. Call sites write `return cliError(...)`

// where subsequent code would dereference narrowed-away values under mock.

// cliError uses console.error (tests spy on console.error); cliOk uses

// process.stdout.write (tests spy on process.stdout.write — Bun's console.log

// doesn't route through a spied process.stdout.write).

/** Write an error message to stderr (if given) and exit with code 1. */

export function cliError(msg?: string): never {

// biome-ignore lint/suspicious/noConsole: centralized CLI error output
