Failure cases for autogen agents

1. extract all telescopes that are up for auction on https://astromart.com/ (using a wrong url; using wrong assumption of the html structure)
2. Find $a + b + c$, given that $x+y \\neq -1$ and
\\begin{align}
ax + by + c & = x + 7,\\
a + bx + cy & = 2x + 6y,\\
ay + b + cx & = 4x + y.
\\end{align}.
(using numpy; need the hint: use sympy)
3. What date is today? Which big tech stock has the largest year-to-date gain this year? How much is the gain? (using outdated ticker FB; need the hint: FB -> META)
