Dialogue Example
### Input template
f"---\nNAME: {theorem.full_name}\n\n"
f"---\nPROOF_BEFORE: {proof_before}\n\n"
f"---\nSTATE_BEFORE: {state}\n\n"
f"---\nTACTIC: "
### Input example
---
NAME: square_sub_one_divisible_eight
---
PROOF_BEFORE: rw [h, pow_two]
---
STATE_BEFORE: m n : N
h : n = 2 * m + 1
⊢ 8 | (2 * m + 1) * (2 * m + 1) - 1
---
TACTIC:
### Output example
rw [← Nat.mod_add_div (2 * m + 1) 8]
