tracing

Normalizes the instruction by stripping whitespace and creating a
SHA-256 hash, then converting to a UUID for LangSmith compatibility.

Args:
    instruction: The task instruction string to hash
    seed: Integer seed to avoid collisions with existing examples

Returns:
    A UUID string generated from the hash of the normalized instruction
"""
# Normalize the instruction: strip leading/trailing whitespace
normalized = instruction.strip()

# Prepend seed as bytes to the instruction for hashing
seeded_data = seed.to_bytes(8, byteorder="big") + normalized.encode("utf-8")

# Create SHA-256 hash of the seeded instruction
hash_bytes = hashlib.sha256(seeded_data).digest()

# Use first 16 bytes to create a UUID
example_uuid = uuid.UUID(bytes=hash_bytes[:16])

return str(example_uuid)
