Add a script that counts Tailscale tailnet entities and slices them several ways for a quick at-a-glance inventory.

What it does

scripts/tailscale-entity-rollup.sh sources coily tailscale status --json and emits a YAML rollup:

  • by_type - people / physical machines / k8s workloads / personal devices (disjoint, sums to total)
  • by_os - linux / macOS / windows / android / iOS (disjoint)
  • by_online - online vs offline (disjoint)
  • by_tag - OVERLAPPING, one node can carry several tags
  • rollup - reconciles the overlap (tagged vs untagged nodes, tag assignments, multi-tagged count)

Defaults baked in

  • Always sources via coily tailscale (audited passthrough, never bare tailscale).
  • Always emits colorized YAML via bat -l yaml. bat auto-detects a terminal, so redirecting to a file writes plain YAML. Falls back to cat when bat is absent.

Person-linked data is limited to masked emails (first letter + domain) in by_type. No display names or owner mapping.
