fix benchmark

[sergical]

always said slower

From Claude Code

⏺ Looking at the benchmark script, the calculation is mathematically correct:

  diff=$(echo "scale=2; $agent_avg - $direct_avg" | bc)
  percent=$(echo "scale=1; ($agent_avg - $direct_avg) / $direct_avg * 100" | bc)

  However, there's a presentation issue - the output assumes agent mode is always slower:

  echo "  +${diff}s (${percent}% slower)"

  Problem: If direct mode is actually slower than agent mode, you'd get confusing output like:
  - +-1.5s (-10% slower)

  The fix should handle both cases:

  # Calculate difference
  diff=$(echo "scale=2; $agent_avg - $direct_avg" | bc)
  percent=$(echo "scale=1; ($agent_avg - $direct_avg) / $direct_avg * 100" | bc)

  # Determine if slower or faster
  if (( $(echo "$diff > 0" | bc -l) )); then
    echo "Difference:"
    echo "  +${diff}s (${percent}% slower)"
  else
    abs_diff=$(echo "scale=2; -1 * $diff" | bc)
    abs_percent=$(echo "scale=1; -1 * $percent" | bc)
    echo "Difference:"
    echo "  -${abs_diff}s (${abs_percent}% faster)"
  fi

  Would you like me to fix this in the script?
