​
TL;DR

User is the per-request scope. Marks “this invocation acts on behalf of alice, in role X.” Async context manager; pushes a fact-bearing Biscuit through the agent runtime. 
from hexgate import User, load_hexgate_agent, stream_agent

agent, handler = load_hexgate_agent("support-bot")

async with User(user_id="alice", role="billing", ttl_seconds=300):
    async for event in stream_agent(agent, handler, "refund 30"):
        ...
The runtime mints the per-request token, picks the billing role’s policy, and evaluates its constraints against each tool call.
