terminal-opener

Open an executable and its argument array in a visible terminal window through a reusable, shell-free launch plan with dry-run, JSON, capability detection, detached fallback, and standalone recovery modes. Use when Codex needs to open an interactive CLI, SSH session, local development process, sandbox, or other argv-based command in a new host terminal; diagnose whether a supported terminal is available; or provide an actionable plan when the requested terminal is unsupported.

# Terminal Opener

Use `scripts/open-terminal.js` to preserve an executable and every argument as
separate process entries. Never interpolate a shell command string. Keep every
spawn on `shell: false`. Default to a non-launching plan. Use `--launch` only
after the user explicitly requests a real window and the argv has been reviewed.
The launched process inherits the full environment of the calling process,
including secret-bearing variables. The launcher does not filter the
environment. Run it from a shell whose environment is safe to expose to the
target command.

## Launch a command

Pass launcher options before `--`, then pass exactly one executable followed by
