Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (2)
🟢wenmar_vin(action, vin, vins, year)
Decode vehicle identification numbers into year, make, model, trim, engine, drivetrain, safety equipment and the matching catalog entry. action=decode takes `vin` (and optionally `year` to override the model year). action=batch takes `vins`, at most 50, and returns one result per VIN in order. A wrong check digit is not an error: the result has valid=false and a warning.

}🟢wenmar_vehicles(action, id, limit, make, model, ...)
Look up vehicles by year, make, model, submodel and engine. Actions: years; makes (optional `year`); models (`make`, optional `year`); submodels (`make`, `model`, `year`); engines (`make`, `model`, `year`, optional `submodel`); search (`query`, such as "2019 civic si" or "chevy 1500"); entry (`id`, such as "2019_honda_civic_si"). `make` and `model` take a name, an alias or an id. `term` narrows a list to names starting with it. `scope` is light (cars, MPVs and trucks; the default), all, or a vPIC vehicle type id.
