user8157: Are there any Suttas, Vinaya or Abhidhamma explaining sīlabbata-parāmāsa in detail?
Please kindly provide examples if knowing. Thank you

user471: Clinging to precepts and practices which lead to increase in unskillful mental qualities and decrease in skillful mental qualities is silabbata paramasa.

"When — by following a life of precept & practice (sīlabbata)
, a life, a holy life
that is followed as of essential worth — one's unskillful mental
qualities increase while one's skillful mental qualities decline: that
sort of precept & practice, life, holy life that is followed as of
essential worth is fruitless. But when — by following a life of
precept & practice, a life, a holy life that is followed as of
essential worth — one's unskillful mental qualities decline while
one's skillful mental qualities increase: that sort of precept &
practice, life, holy life that is followed as of essential worth is
fruitful."
AN 3.78

Also, purity of virtue is for the sake of purity of mind.
Clinging to the right precepts and practices, beyond the purpose of mental purification, is also silabbata paramasa, based on the raft simile of MN 22.

"In the same way, my friend, purity in terms of virtue (sīlavisuddhi)
is simply for
the sake of purity in terms of mind (cittavisuddhi).
Purity in terms of mind is simply
for the sake of purity in terms of view. Purity in terms of view is
simply for the sake of purity in terms of the overcoming of
perplexity. Purity in terms of the overcoming of perplexity is simply
for the sake of purity in terms of knowledge & vision of what is & is
not the path. Purity in terms of knowledge & vision of what is & is
not the path is simply for the sake of purity in terms of knowledge &
vision of the way. Purity in terms of knowledge & vision of the way is
simply for the sake of purity in terms of knowledge & vision. Purity
in terms of knowledge & vision is simply for the sake of total
Unbinding through lack of clinging. And it's for the sake of total
Unbinding through lack of clinging that the holy life is lived under
the Blessed One."
MN 24


In the same way, monks, I have taught the Dhamma compared to a raft,
for the purpose of crossing over, not for the purpose of holding onto.
Understanding the Dhamma as taught compared to a raft, you should let
go even of Dhammas, to say nothing of non-Dhammas."
MN 22
