There are some additional things I need to implement first but I do have a hands on repo that you actually try at

https://github.com/gitsense/gsc-rules-demos

One of the rules shows how you can inject information when you know an agent wants to read a certain file. So if you have skills related to a certain file/directory, you can inject the information when you need to.

So using the OPs visualization tool, if you find the agent wandering you could create a new rule to guide the agent and compare it with and with guidance.
