The Reclassify tool in Spatial Analyst offers automatic classification methods (Jenks, quantile, equal intervals, etc.). However, when using the tool in scripting (Python, ModelBuilder…) the class boundaries can only be hard coded. E.g. in ModelBuilder boundaries are set from the raster used at model development and do not adapt to other rasters passed as arguments to the model. This makes automatic reclassification useless in programming.
Thus the following suggested improvement: the classification method keyword and its parameters should be “programmable” along with the tool.
