Hi shashank, if you want to start developing application using Agentry, I think you should first understand what are all the tools provided by Agentry platform and how to uses them, you can refer to this site for documentation and manuals for Syclo. https://sycloresourcecenter.sap.com/
if you are not registered with this site, then you have to request for access send a request message to support@syclo.com. Once the access is granted you can explore all the documents you need.
hope this'd be helpful.
