moth setup [--yes] [--dry-run] [--url http://127.0.0.1:4747] [--timeout 300]
1 packages python, torch, tokenizers / safetensors / numpy, and PySide6 for the desktop pet. Anything missing:
the exact pip command, run only when you say yes at the prompt (never by --yes, never with sudo).
2 weights pip install: offers to download them (about 860 MB, into ~/.cache/moth/<repo>). Hugging Face download:
checks they're complete (`moth update` or `hf download` finish a partial one).
3 memory moth needs about 1 GB; the pet won't wake it with less than ~3 GB free.
4 hooks the coding agents found here and whether moth is hooked in; one question per harness, installed
by moth/hooks.py (backs up and merges configs). Then show_in_harness (Pi / OpenCode, default off).
5 autostart start the pet at login (moth/autostart.py).
6 the pet start it now, detached, and wait until moth answers on /api/health. Logs: ~/.moth/pet.log and the
server's log (~/.moth/serve.log).
Each step says what's already done and only offers what's missing, so running it again is safe. --yes takes every
default; --dry-run only prints. Without a terminal to ask in (CI, a pipe) it behaves like --dry-run unless --yes is
given. Exit 0 when moth can run here and nothing failed (a declined hook or autostart is fine), 1 otherwise; a dry run
exits 0. Stdlib only at import (torch and PySide6 are probed in child processes).
