Took me a bit longer to get this one but still quite simple overall.
Spent quite some time on getting to know the try and assert operators better.

Run with example input here

# Get the indices matching the ascending/
# descending criteria
CheckAsc ← ≡°□⍚(⍣(⊸⍤.≍⍆.)⍣(⊸⍤.≍⇌⍆.)0)
# Get the indices matching the distance criteria
CheckDist ← ≡°□⍚(⍣(⊸⍤.≠1∈:0)0×⊓≥≤1,3⌵⧈-)
Split     ← ⊙(▽≠1)▽,,

PartOne ← (
  &rs ∞ &fo "input-2.txt"
  ⊜(□⊜⋕≠@ .)≠@\n.
  CheckAsc.
  ▽
  CheckDist
  ⧻⊚
)

PartTwo ← (
  &rs ∞ &fo "input-2.txt"
  ⊜(□⊜⋕≠@ .)≠@\n.
  CheckAsc.
  Split
  CheckDist.
  Split
  ⊙(⊂)
  ⧻

Decided to try and use Uiua for each day this year. At least I'm not the only one to get this idea ^^

Run with example input here

PartOne ← (
  &rs ∞ &fo "input-1.txt"
  ⊜(⊜⋕≠@ .)≠@\n.
  ≡⍆⍉
  ⌵/-
  /+
)

PartTwo ← (
  &rs ∞ &fo "input-1.txt"
  ⊜(⊜⋕≠@ .)≠@\n.
  ⊢⟜⊣⍉
  0
  ⍢(+⊙(:⊙(×⧻⊚◡⌕)↘1⟜⊢)|⋅(≠0⧻))
  ⊙(◌◌) # just cleaning up the stack
)
