Add Occam's razor

A lot of our templated ADBC examples are more verbose than they strictly need to be. For example, in the quickstarts, this:

dbapi.connect(
    driver="postgresql",
    db_kwargs={"uri": "postgresql://postgres:mysecretpassword@localhost:5432/demo"},
)

can be reduced to this:

dbapi.connect("postgresql://postgres:mysecretpassword@localhost:5432/demo")

It'd be great if the ADBC agent skill incorporated an instruction to be concise where possible, with details about how.
