Yes, I deleted it so I could see if the agent worked without it because I had a similar issue yesterday when trying to add urls but the agent worked fine when I removed the urls. Today it didn't work with or without the pdf added but I will add it now. I am wondering if the problem is usernames. I mention a number of stacker news users in the pdf with @username. Maybe this is the issue. Also would have caused an issue with the urls as @usernames were included.
