Query: A simplification of "Effective quasimorphisms on right-angled Artin
  groups"   This paper presents a simplification of the main argument in "Effective
quasimorphisms on right-angled Artin groups" by Fern\'os, Forester and Tao.
  Their article introduces a family of quasimorphisms on a certain class of
groups (called RAAG-like) acting on CAT(0) cube complexes. They show that these
have uniform defect of $12$ and take the value of at least $1$ on a chosen
element. With the Bavard Duality they conclude that hyperbolic elements of
RAAG-like groups have stable commutator length of at least $1/24$.
  Their proof that the quasimorphisms take the value $1$ is quite technical and
relies on some tools they introduce: the essential characteristic set and
equivariant Euclidean embeddings. Here it is shown that this is unnecessary and
a much shorter proof is given.
  This was originally part of my master thesis "Stable commutator length gap in
RAAG-like groups" supervised by Alessandra Iozzi at ETH Z\"urich.
