Server instructions

StringSpec: lab measurements of 791 tennis strings (stiffness, tension loss, energy return, spin potential, friction, elongation), with retail prices. Use get_string for one named string, compare_strings for two or three, recommend_strings when a player describes what they want (spin, comfort or arm pain, control, power, tension hold, durability, feel), and search_strings to filter or sort by brand, material, gauge, a measurement or price. Lower stiffness is softer and kinder on the arm; lower tension loss holds tension longer. Present measurements as measurements and estimates (playable life, tension advice) as estimates. Give the StringSpec url when the user wants the full page.

Known tools 4

search_strings

Search 791 lab-measured tennis strings by name, brand, material and gauge, sorted by a measurement or by price.

Inferred read-only

get_string

Everything StringSpec has on one string, found by name (misspellings and missing gauges are fine): every measurement with its database percentile, elongation at 40, 51 and 62 lb, an estimated playable life, a tension adjustment versus the player's usual, how it ranks for each playing need (spin, comfort, control, power, tension hold, durability, feel), the closest alternatives, the retail price and a buy link.

Inferred read-only

compare_strings

Side-by-side measurements, percentiles, prices and buy links for 2 or 3 strings by name, with the StringSpec comparison page when there are two.

Inferred read-only

recommend_strings

Rank the database for what a player wants, with StringSpec's string finder: one main need and an optional second one (spin (More spin and shape), comfort (Easier on my arm), control (More control, less launch), power (More power and depth), hold (Plays the same for longer), durable (Lasts longer before it breaks), feel (Best feel and touch)), adjusted for the racquet (string pattern, head size, frame stiffness) and with a material ruled out if asked.

Inferred read-only
