rgthree-comfy

rgthree-comfy is one of the most widely installed packs, so its nodes turn up in a large share of community workflows. Three of its properties make it a recurring agent-failure mode — all three fail quietly enough to look like success.

The three things that catch agents out

1. Some rgthree nodes are FRONTEND-ONLY. They are registered by the pack's JS (registerCustomNodes()), have no Python class, and are therefore absent from /object_info by design. Checking /object_info and concluding "this node doesn't exist" is wrong. /object_info lists 24 rgthree backend types; the toggles are not among them.
