The probe skill was a Claude-only file, and its promises held on one machine: its shield needs an
account named probe and digits, which CONTRIBUTING never asks for, and its long-run advice was
macOS's. The switches every checkout has for an unattended run are plain text in CONTRIBUTING
now, read by any tool; METHOD points there, AGENTS.md drops the skills folder, and .gitignore
leaves .claude/ to each person.
