implement-pythonpart

Implements an ALLPLAN 2027 PythonPart from an accepted implementation plan, or applies a clearly specified change to PythonPart scripts (.py) and parameter dialog files (.pyp). Looks up the framework APIs and examples, writes the code, and type checks it until it is clean. Use when the user asks to implement a PythonPart plan, write or modify a PythonPart script or pyp file, or add a parameter to a PythonPart. Does not gather requirements or plan; use the plan-pythonpart skill for that.
