Interesting approach. Context management for agents is an underexplored area. I've been looking at similar problems - the key challenge is keeping token usage low while giving the agent enough context to be useful. Tiered retrieval (facts first, full text only whenneeded) seems to work well in practice.

Agreed, in addition to this I'd say it's better to spend tokens once while ingesting the sources and storing the canonical reusable definition rather than having agents do the full exploration over and over again
