Load the codex-claude-loop skill, source its lib, and run cl_doctor.
Report each check plainly. If codex is missing, point at npm install -g @openai/codex
then codex login. If the repo resolved is not the one the user means, tell them to set
CL_REPO. Do not start a wave until every check passes.
If the user is running this harness for the first time, offer cl_selfreview — Codex
adversarially reviewing this harness before they trust it with their tree.
