Accepting filters for function calls

[cs168898]

**Is your feature request related to a problem? Please describe. ** I saw a 'TODO:' in the source code (base_flow.go lines 363) for filtering function calls, I would like to check how would the function calls in the filter be defined? Through the agent dynamically generating it or through user definition or another way I have not thought of.

Describe the solution you'd like I hope to have a clear idea on how the filters will be defined, in order to build the filter as well as the filter acceptance functionality.

Additional context I have just started using and learning this project recently, hoping to contribute in some way 😀
