Perhaps Mathstodon can be a place to note some folklore that are useful but too trifling to devote an entire paper to. Here's one (that I recalled on browsing MathOverflow mathoverflow.net/questions/435): If one is trying to prove a Hilbert space identity or inequality which is invariant under a unitary group action, one can often reduce "for free" to the irreducible components of that group action.
