Use this notebook to inspect the real-time runtime stream, collected event packets, and frontend-ready packet transports.
Its imports and arguments are checked against shipit-agent 3.0. The outputs were saved when it was written, for an earlier release.

# ── IMPORTANT ─────────────────────────────────────────────────────────────
# Disable the built-in planner for this demo.
#
# shipit ships a `plan_task` tool that runs BEFORE the first LLM call
# whenever the router policy decides the prompt is "plan-ish" (long, or
# containing keywords like "plan", "research", "task"). It injects a static
# scaffold ("Goal: … Plan: 1. Clarify … 2. Select the right tools …") into
# the message history as a user-role context message.
#
# That scaffold primes many models (gpt-4o-mini, gpt-oss-120b, even Claude)
# to answer by *describing* a plan instead of *executing* one — which is
# exactly what you were seeing: 7 events, no `tool_called`, final answer is
# a prose "Step-by-step plan (executed)" with zero real tool calls.
#
# For a tool-use demo we want the model to call tools directly. Kill auto-plan:
agent.router_policy = RouterPolicy(auto_plan=False)
# Also raise the iteration cap — a 2-source research task realistically
# needs 5–6 tool loops (search, open_url, open_url, maybe retry, summarize).
agent.max_iterations = 8
# Tighter prompt: removes plan-coded keywords and adds a hard stop condition
# so the model cannot loop forever waiting for perfect data.

"2. Call `open_url` on TWO different domains and extract the current price "
