rope
Let an agent explain ropes, their materials and constructions, relay strength ratings and safety standards from public sources, describe specialised ropes, and distinguish rope from cord, cable and string.
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 ropes, their materials and constructions, relay strength ratings and safety standards from public sources, describe specialised ropes, and distinguish rope from cord, cable and string.
A length of strong fibres or wires twisted or braided together to give tensile strength, made from natural fibres such as hemp, manila, sisal and cotton, synthetic fibres such as nylon, polyester, polypropylene and aramid, or steel as wire rope, used for hauling, lifting, mooring, climbing, rescue, agriculture and play, with specialised forms such as climbing rope, skipping rope, bowden cable and traditional whips and weapons such as the Karbatsche and meteor hammer; ropes are rated by construction, diameter and breaking strength.
What it is for: Pulling, lifting, securing and climbing.
It can be explain materials and constructions; relay ratings and standards; describe specialised ropes; distinguish from cord and cable.
Distinguishing features
Tensile strength
Twisted or braided construction
Material variety
Safety-rated uses
What it looks like
A flexible twisted or braided line, from a few millimetres to many centimetres thick.
Physical character
nylon rope strength: about 1000 kg per cm^2 of cross-section approximate - varies by construction
dynamic climbing rope diameter: about 8.5-11 mm
wire rope: steel strands around a core construction
How it is recognised
Twisted or braided line of fibres or wires
Natural fibre, synthetic, wire rope; climbing, skipping, mooring, bowden cable
Cord and string are thinner; cable may be electrical; chain uses links
