would be nice to rebase shell_command on top of this

Yep! In the end I think it will allow us to keep only unified_exec

there is lots of logic in /Users/pakrym/code/codex/codex-rs/core/src/exec.rs that I'm afraid we'll rediscover again with a separate implementation

we have an entire thing to kill trees of child processes in shell_command

Instead of starting with a completely new pipe implementation can we reuse/extend/share the one we have for shell_command?

The stdout/stderr reader tasks spawned here are only awaited by reader_handle, but ProcessHandle::terminate (and Drop) only aborts that one handle; the actual stdout/stderr tasks are not stored anywhere. If a child process is terminated while a grandchild keeps stdout/stderr open, those reader tasks will keep running indefinitely, leaking tasks and continuing to read from the pipes. Consider storing those JoinHandles (or wiring a cancellation token/timeout) so terminate() can abort the actual reader tasks.
Useful? React with 👍 / 👎.

Update exec_command description to match pipe default
The tool spec still says exec_command “Runs a command in a PTY”, but this commit changes the default to pipe mode unless tty=true. Clients (including the model) often rely on the top‑level description rather than per‑field docs, so they may omit tty and end up running commands that require a TTY (e.g., interactive prompts, isatty‑gated behavior) in non‑TTY mode, causing hangs or different output. Consider updating the description to reflect the new default and the tty flag.
