 - **`rewindFlag`** — `--rewind`. Use for subscribe commands that support message replay (default: 0).
 - **`timeRangeFlags`** — `--start`, `--end`. Use for history and stats commands. Parse with `parseTimestamp()` from `src/utils/time.ts`. Accepts ISO 8601, Unix ms, or relative (e.g., `"1h"`, `"30m"`, `"2d"`).
-- **`forceFlag`** — `--force` / `-f`. Use for destructive commands (delete, revoke) that require user confirmation. When `--force` is provided, skip the interactive prompt. When `--json` is used without `--force`, fail with an error requiring `--force`. Use `promptForConfirmation()` from `src/utils/prompt-confirmation.js` for the interactive prompt — do NOT use `interactiveHelper.confirm()` (inquirer-based, inconsistent UX).

 There are some relevant Node.js projects we can draw inspiration from:
 
 - [Vorpal interactive CLI](https://vorpal.js.org/) with source code at https://github.com/dthree/vorpal
-- [Inquirer package](https://www.npmjs.com/package/inquirer) for common interactive command line user interface commands
+- Node.js built-in `node:readline` module for interactive prompts (confirmation, selection)
 
 [oclif](https://oclif.io/) does not appear to have any plugins to support an interactive/embedded CLI mode.
 However, a [REPL plugin](https://github.com/sisou/oclif-plugin-repl) exists, although that's unlikely to share much with the goals of interactive CLI.
