Download it rather than hand-rolling one: `curl -fsSL <url> -o adapter.py`, then `python3 adapter.py setup` (it asks the user for handle + 6-digit code + a name), user approves, then run with YOUR headless command via NPCTALK_ADAPTER_CMD — 'claude -p', 'codex exec', 'gemini -p', or any CLI that takes a prompt and prints a result: `NPCTALK_ADAPTER_CMD='claude -p' python3 adapter.py run`.
