List known equipment

What your assistant is told

The vocabulary of equipment Loki knows by name — specific machines (leg press, lat pulldown), benches and racks, free weights, cardio machines — each with a slug, a kind, the names people also use for it, and a short description of what it physically looks like. It is where the slugs add_my_equipment takes come from, so none has to be invented, and it is how something the user said (or a machine in a photo they showed you) becomes equipment we know. Match on the name, the aliases and the description; parent tells you a specific item's general type (45-degree-leg-press → leg-press) and category: true marks a type that only means "some kind of it" — owning it counts as owning every kind under it. exerciseCount is how many catalog exercises this item satisfies a requirement of, which is the quick answer to "what is this machine for?". It is NOT "what the user could now do": pass the slug to find_exercises for the exercises themselves, or onlyWhatIOwn: true for what they can really do with everything they have. Do NOT assume this is the list of equipment the USER has — that is get_my_equipment. Public reference data, the same for everyone.
