"""Tool Trajectory verification script with detailed logging.

This script verifies the research agent tools work correctly by:
1. Testing each tool individually with logging
2. Verifying the tool call sequence (trajectory)
3. Outputting detailed logs for debugging

Usage:
    uv run python scripts/verify_tool_trajectory.py
