Got it! Thanks Artem. 'trace-condition' for the collection name makes perfect sense then. The alias prefix works too but I lean towards a shorter version because the prefix is always qualified by the collection name so you always have both in a command: 'show trace-condition trace-condition0'.  For example, for tunnel zones, the collection is called 'tunnel-zone' but the alias prefix is 'tzone', even something like 'tz' would work for me in that case.

Sorry for the nitpicking but because this is very user visible I really want all the CLI naming to feel consistent all around.
