From team-kit
Build or adapt a local harness to drive, inspect, and profile an interactive CLI or TUI without external services. Use for CLI UX checks, startup regressions, memory leaks, hangs, prompt flows, or terminal demos.

Use a repeatable local harness to exercise an interactive CLI instead of poking at it manually. First reuse the repo's own test/demo harness if it exists; otherwise assemble a temporary harness from standard local tools.

tmux: managed sessions, capture-pane, send-keys, attach/detach.SESSION="cli-harness-$(date +%s)"
tmux new-session -d -s "$SESSION" -- <command-under-test>
tmux capture-pane -pt "$SESSION"
tmux send-keys -t "$SESSION" "help" Enter
tmux capture-pane -pt "$SESSION"
tmux kill-session -t "$SESSION"
For Node CLIs:
NODE_OPTIONS="--inspect=127.0.0.1:0" tmux new-session -d -s "$SESSION" -- <node-cli-command>
Read the terminal output to find the inspector URL, then use Chrome DevTools-compatible tooling if profiling is needed.
Use a PTY script when you need deterministic waits in a repo that does not have tmux or a demo harness. Keep it temporary unless the user asks to add a reusable test.
import os
import pty
import select
import subprocess
import time
master_fd, slave_fd = pty.openpty()
proc = subprocess.Popen(
["<command>", "<arg>"],
stdin=slave_fd,
stdout=slave_fd,
stderr=slave_fd,
close_fds=True,
)
os.close(slave_fd)
deadline = time.time() + 30
buffer = b""
while time.time() < deadline:
ready, _, _ = select.select([master_fd], [], [], 0.25)
if not ready:
continue
chunk = os.read(master_fd, 4096)
buffer += chunk
if b"<ready text>" in buffer:
os.write(master_fd, b"help\n")
break
print(buffer.decode(errors="replace"))
proc.terminate()
os.close(master_fd)
If the CLI needs richer terminal control, use pty.fork() or an existing PTY library.
/tmp unless the repo already has a testing/demo harness.Guides creation, editing, and verification of skills for AI coding agents using test-driven development with subagent scenarios. Use when authoring or debugging skills.
