Id be careful adding coffee grounds directly to soil you plan to plant in soon.
they can be very acidic . any any nutrients from them need to be broken down first.
depends a bit on how much coffee you drink , and eggs you eat.
Soils in my corner of the world tend to be acidic so my additions are a mix of coffee grounds, eggshells, and lime mixed with peat moss, some vermiculite and composted manure. One thing one doesn't want to do here is decrease the pH of the soil.
