-# Agents
-
-Agents can be viewed as an FSM using an LLM to generate inputs into the system that operates over a DAG.
-
-What this really means is that the agent is just a function without memory that uses text inputs and outputs in a
-defined order.
-
-```python
-def my_agent(*args, **kwargs) -> str:
-    # do whatever you want!
-    return "Hi I'm an agent!"
-```
-
-Now obviously, that's like saying water's wet, but we're going to be using that definition to inform our design of the
-library, namely, that we should *not* store agent state outside the function call.
-
-## The Agent Class
-
-So we don't have state, why are we using a class?
-
-Well, we want to initialize things, we want to have some configuration, and we want to have some helper functions.
-Preferably all in a single place.
-
-```python
-class BaseAgent:
-    def agent_primitives(self) -> list[BaseAgent]:
-        # Returns a list of Agents that are utilized by this agent to generate inputs
-        # We use agent primitives here instead of subagents because these are going to be part
-        # of the message graph, not a subagent tool call.
-        raise NotImplementedError
-    
-    def tools(self) -> list[BaseTool]:
-        # Returns a list of tools that the agent needs to run
-        raise NotImplementedError
-    
-    
-    def run(self, config, *args, **kwargs) -> ConversationGraph:
-        llm = get_llm(config)
-        tools = self.tools()
-        for agent in self.agent_primitives():
-            tools.extend(agent.tools())
-        tools = remove_duplicates(tools)
-        tools = initialize_tools(tools, config)
-        return self(llm, tools, config, *args, **kwargs)
-    
-    @staticmethod
-    def __call__(self, llm, tools, config, *args, **kwargs) -> ConversationGraph:
-        # Returns a ConversationGraph that can be parsed to get the output of the agent
-        # Use w/e args/kwargs you want, as long as llm/tools/config are satisfied. 
-        raise NotImplementedError
-```
-
-Doesn't seem too bad (I hope), it is a bit annoying that we don't initialize everything in the constructor, but
-hopefully we all kinda like it :)

-# LLM Client
-
-A quick wrapper over openai apis
-
-## Responsibilities
-
-- Transform "normal" chat/completions requests into graphs
-- Translate graphs into LLM requests
-- Keep a history of graphs parsed by it
-  - On Policy Data
-  - Deduplicating graphs, so we don't keep previous history as separate graphs
-
-## How to use
-Exactly the same as the openai api! Just with the additional support of graph inputs and outputs.

-Messages should be a graph (DAG, specifically) of immutable elements.
-
-## Why immutable elements?
-We want to train on policy
-- This means the context cannot change after we call a response.
-
-## Why a graph?
-Nodes and connections are a natural way to represent the flow of information in an agent conversation.
-
-## Will this be annoying to deal with?
-
-It shouldn't be! While there will be internal stuff that may look ???, for the interface, it should be as simple as your
-normal context window edits, so `message_history[2]['content'] = my_edit`, but internally we'll deal with the recordkeeping
-and how this ends up parsing into on policy training data, if requested.
-
-## Edges
-
-Edges are the connections between nodes, and there are two types we are concerned with:
-- **Sequential edges**: These represent the flow of conversation, connecting messages in the order they were sent. For example, a user message followed by an assistant response.
-- **Parallel edges**: These represent versioning, e.g. edit history, context squishing, etc.
-We, however, are only concerned about parallel edges when we break the prefix, and ignore any other parallel edges.
-
-## So what does this look like in practice?
