Multi-step research agent
The research agent is inspired by this project and BabyAGI.
The idea is as follows: we start with a research question and some source of data we can retrieve from. We retrieve the data relevant for the original question, but then instead of feeding it into the LLM prompt to answer the question, like a conventional RAG would do, we use it to ask an LLM what further questions, based on the retrieved context, would be most useful to answer the original question. We then pick one of these to do retrieval on, and by repeating that process, build a tree of questions, each with attached context, which we store as a knowledge graph.
When we decide we’ve done this for long enough (currently just a constraint on the number of nodes), we then walk back up the graph, first answering the leaf questions, then using these answers (along with the context retrieved for their parent question) to answer the parent question, etc.
Technically speaking, the flow consists of two tasks, QuestionTask and AnswerTask. The QuestionTask starts with a user question, and embeds this into the graph as the first un-answered question. Its get_next_unit() method looks up all the as yet un-answered questions, and chooses the one that’s most salient to the original question (so that question is the TaskUnit it returns). Its worker then retrieves the context (RAG-style) for that question, but instead of answering it,
creates up to 3 further questions that would be most helpful to answer in order to answer the original question. We thus build up a tree of questions, where each non-leaf node has a retrieval context attached to it - all stored in the knowledge graph for easy retrieval. This goes on until we have enough questions (currently just a fixed number of iterations).
The AnswerTask then rolls the tree back up. It ignores all the questions without a retrieved context; and the TaskUnit that its get_next_unit() returns is then any question that has no un-answered children. Its worker then proceeds to answer that question using its retrieved context and the answers from its children, if any. This goes on until we’ve worked our way back up to answering the original question.
This shows how the tasks can create TaskUnits for themselves and for each other, which enables a whole new level of self-organization.
The different Tasks don’t have to all form part of a connected DAG either. For example, two tasks could take turns creating TaskUnits for one another - just one of many interaction patterns possible within the architecture.

Question: Why did Arjuna kill Karna, his half-brother?
Answer: Arjuna killed Karna despite him being his half-brother because of the overriding principle of dharma (righteous duty) that governed the war. Although Karna was Kunti’s eldest son and thus Arjuna’s brother, Karna fought on the Kaurava side, opposing the Pandavas. Karna had promised Kunti he would spare her other sons but would fight Arjuna in mortal combat. When Kunti revealed Karna’s identity, Krishna explained that had the Pandavas known earlier, they would not have fought, but "you had to fight. It was dharma. All is as it must be." This shows that the warrior code prioritized duty to righteousness and cosmic order above familial ties. Krishna’s counsel to Bhima after killing Vikarna—"Dharma is what matters. Not family. Not friends. Dharma."—further underscores that adherence to dharma justified Arjuna’s act. Thus, Arjuna’s killing of Karna was an act fulfilling his warrior dharma, overriding personal and familial bonds in the context of the great war.
