Root cause of the never-passing agent-tools wait gate, revealed by #224's stderr surfacing:

nix build --no-link --print-out-paths nixpkgs#skopeo prints one path per output, and skopeo in current nixpkgs has two (man and out):

/nix/store/giy0w...-skopeo-1.23.0-man
/nix/store/q9ds7...-skopeo-1.23.0

The step's skopeo="$(nix build ...)/bin/skopeo" captures both lines, so every invocation tried to exec ...-man<newline>.../bin/skopeo → 'No such file or directory' on every retry, for the gate's whole lifetime (#221 onward) — indistinguishable, pre-#224, from the tag not resolving.

Fix: build nixpkgs#skopeo^out so exactly one path is printed.
