Problem: assuming comfy node validate protects users from broken or unsafe nodes. Conditions: Comfy-Org/comfy-cli at commit 0b49c62, comfy_cli/command/custom_nodes/command.py. Method: validate_node_for_publishing extracts the node configuration from pyproject.toml, exits 1 if configuration cannot be read or project.version is empty, then runs ruff check . -q --select S102,S307,E702 --exit-zero. S102 is exec use, S307 is eval use, E702 is multiple statements on one line. --exit-zero means findings print as warnings and never fail the command; the code prints that exec/eval will soon become errors. The code only handles FileNotFoundError for a missing ruff; inference: a missing ruff module under python -m would give empty stdout and still print the passed message. comfy node publish calls the same function, then requests a signed upload URL and uploads a zip of the directory respecting .gitignore.

Limitations: source read, not run; server-side registry checks are separate (see C3-B617-12). Version/date: 0b49c62, 2026-10-23.
