wrench
Let an agent explain wrenches and their kinds, relay sizing, standards and use from tool references, describe specialised and powered wrenches, and distinguish wrenches from pliers, screwdrivers and the British and American naming differences.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain wrenches and their kinds, relay sizing, standards and use from tool references, describe specialised and powered wrenches, and distinguish wrenches from pliers, screwdrivers and the British and American naming differences.
A hand tool for gripping and turning nuts, bolts, pipes and fittings, called a spanner in British English, in forms from open-ended, ring and combination spanners through adjustable and socket wrenches, tube spanners for recessed nuts, spanner wrenches with pins for slotted collars, oil-filter wrenches and specialised tools such as the Basque wrench to powered impact wrenches; wrenches are standardised by size and are among the most common tools.
What it is for: Turning nuts, bolts and fittings.
It can be explain kinds; relay sizing and standards; describe specialised tools; distinguish related tools.

What the second pass must settle

- How should tool references be linked?
- The registry entry has merged aliases naming specialised tools and a pin vise; should they be split off?
