You don't.

If you really wanted to add to the AGI environment variables, you could 
hack on res_agi.c, but I don't think this is what you want to do.

I'm thinking you want channel variables.

It's a piece of cake to read and write channel variables in the dialplan 
using ${} and SET(). It's only slightly more difficult to read and write 
channel variables in your AGI using "GET VARIABLE" and "SET VARIABLE."

Just decide on a meaningful name, SET() it in the dial plan and "GET 
VARIABLE" in your AGI.

Thanks in advance,
