I'd rephrase to say, you should have a concrete idea what will probably
happen to the signal(s) as a result of adding or removing an operation --
and this is to avoid sending invalid or dangerous signals to the speakers.
In my mind at least, that's a bit different from having a specific goal in
mind. Part of the process is, "I wonder what it sounds like if I do...?" but
this process should also take valid numeric results into account.

I find it helpful to think in terms of signal ranges. If I know that
SinOsc.ar ranges -1 .. +1, then I can predict that SinOsc.ar * 0.5 will
range -0.5 .. +0.5, and SinOsc.ar * 0.5 + 1 will range +0.5 .. +1.5, and so
on (and this is no longer valid as an audio signal, but it would be ok as an
LFO to control some other UGen). When I add something to a SynthDef, I may
not know exactly what it will sound like, but I can check my ranges and be
reasonably sure I'm not doing something crazy or deafening.
