Create the assistant

import openai, os

assistant = client.beta.assistants.create(
    name="DPX Treasury Assistant",
    instructions="""You are a DPX treasury intelligence assistant.

For any settlement or pricing request:
1. Call check_oracle_stability — if UNSTABLE, advise the user to wait
2. If a counterparty wallet is known, call get_esg_score
3. Call get_settlement_quote with amount, FX flag, and ESG score
4. Present: oracle status, ESG standing, fee breakdown, net recipient amount""",

Handle tool calls
