A side panel (F9, only when developer mode is on) lists entries by category:
animals and plants are auto-populated from their defs (so modded content shows up
automatically), plus action tools. Spawn entries arm a "tool in hand" — left-click
the world to spawn at the cursor (right-click clears); action tools (injure/kill/
infect) apply to the currently selected creature, so you can line up entities and
damage them to compare. Moddable via a new DevToolDef def type: mods add buttons
referencing a code handler kind (spawn-animal/plant/infect/damage/kill) + target,
without touching code. Localized dev.* ru/en. Build + --check-content clean
(13 def types).
