There is, however, an internal check inside the Counter-Strike client.dll that will make the game simply exit if a debugger is detected in the system. Using the normal Counter-Strike client.dll it is NOT possible to debug your bot inside a listenserver.

What you can do however, is debug a DEDICATED server, then connect to it using the loopback connection :

hl.exe -dev -console +connect 127.0.0.1:27015

this command line will make HL connect to the HLDS server that is running on your OWN machine (this way you will be able to debug your bot while you are playing the game).
