Birahu Blackstaff:
We're going to use cantrips and Orisons? Where is the list? Not in the PHB.
It does exist in the PHB as a single 1st level spell. Although the limitations given may be hard or difficult to adjudicate on the fly for the DM, so if you have a specific effect in mind, finding a corresponding (existing cantrip) can help or at least confirm hey this is something a cantrip can actually do.

Cantrips are minor spells studied by wizards during their apprenticeship, regardless of
school. The cantrip spell is a practice method for the apprentice, teaching him how to tap
minute amounts of magical energy. Once cast, the cantrip spell enables the caster to
create minor magical effects for the duration of the spell. However, these effects are so
minor that they have severe limitations. They are completely unable to cause a loss of hit
points, cannot affect the concentration of spellcasters, and can only create small,
obviously magical materials. Furthermore, materials created by a cantrip are extremely
fragile and cannot be used as tools of any sort. Lastly, a cantrip lacks the power to
duplicate any other spell effects.
Whatever manifestation the cantrip takes, it remains in effect only as long as the
wizard concentrates. Wizards typically use cantrips to impress common folk, amuse
children, and brighten dreary lives. Common tricks with cantrips include tinklings of
ethereal music, brightening faded flowers, glowing balls that float over the caster's hand,
puffs of wind to flicker candles, spicing up aromas and flavors of bland food, and little
whirlwinds to sweep dust under rugs. Combined with the unseen servant spell, it's a tool
to make housekeeping and entertaining simpler for the wizard.
According to a strict definition my idea of a cantrip "magic thistle" would it violate the rule or not:
Per the spell description "They are completely unable to cause a loss of hit points"
But what about the loss of 1 hit point? singular? the rule seems to be plural, or poorly written......
The list comes straight out of 1st edition I believe, republished in 2nd in something like "spell compendioum 4"? or something like that.....
