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.

This skill provides a utility to safely launch executables in a visible terminal window (WezTerm) while avoiding shell injection vulnerabilities. It includes input validation and correctly discloses that launched processes inherit the parent process's environment variables.

What does this agent skill do?
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
its argument array:
node skills/terminal-opener/scripts/open-terminal.js \
--launch \
--cwd /absolute/host/path \
-- ssh -t example.test command-with-arguments
Run normal mode first. Let WezTerm try its mux with a new window, then let the
launcher fall back to a detached wezterm start process if the mux is not
available. When fallback is used, read muxFailure from JSON output (or the
human-readable failure line) to diagnose why the mux path failed.
Recover from terminal configuration
Add --recover or --standalone when user configuration or mux state may
interfere with the requested command. Start a detached WezTerm process with:
--skip-config start --always-new-process
Expect recovery mode to skip all user terminal configuration intentionally.
Inspect before launch
Omit --launch (or add --dry-run) and add --json to inspect the exact
executable, argv, working directory, terminal adapter, primary launch, and
fallback without opening a window. Treat the JSON plan as the composition
boundary for callers.
Run --detect --json without a command to probe terminal availability. Follow
the returned action when the adapter is missing or unsupported. Use WezTerm
for the current adapter; treat other requested terminals as unsupported plans,
not as commands to execute.
