description = ''
Pre-fetch the agent-base container system closure, which every
agent builds from, into the host's /nix/store as part of this
host's NixOS build, instead of letting the first agent spawn
do all the work.
Enabling this adds roughly the full nixpkgs runtime closure +
claude-code + the harness binary to your system closure size
(low single-digit GB), but the first `nixos-container start`
for any agent then completes in seconds instead of minutes
because nothing's left to fetch.
Off by default because the toplevel is pinned to
`x86_64-linux` (nixos-containers run native arch). Enabling
on an aarch64 host would force nix to build the x86 closure
via cross or a remote builder, which is rarely what you want.
Flip to `true` on an x86_64 host when you care more about
first-spawn latency than host store size — or just
`nix build .#agent-base-toplevel` once manually to warm the
store.
