The main entry point for the agent loop is the `tool_use_agentic` method, which sets up the initial state and then calls into the `agent_loop` method to repeatedly select and execute tools until a terminating condition is met. + +## Key Components + +### SessionService + +The `SessionService` is responsible for managing sessions, which represent conversations between the user and the agent. It provides methods for: +- Creating new sessions +- Handling user messages +- Managing the agent loop +- Saving and loading sessions from storage + +### Session + +The `Session` class represents a conversation between the user and the agent. It maintains: +- A list of exchanges (messages between the user and agent) +- A list of action nodes (representing tools used by the agent) +- Project metadata (labels, repository reference) +- User context + +### ToolUseAgent + +The `ToolUseAgent` is responsible for determining which tool to use next based on the current state of the session. It uses an LLM to make this decision, taking into account: +- The conversation history +- Available tools +- User context +- Previous tool outputs + +### Agent Loop Flow + +The agent loop follows these steps: + +1. **Initialization**: + - A new session is created or loaded from storage + - The user's message is added to the session + - The agent loop is started + +2. **Loop Execution**: + - The `agent_loop` method is called, which repeatedly: + - Saves the current session state to storage + - Creates a new exchange ID for the next tool use + - Gets the next tool to use by calling `session.get_tool_to_use()` + - Invokes the selected tool with `session.invoke_tool()` + - Processes the result and updates the session state + - Continues until a terminating condition is met (like AttemptCompletion or AskFollowupQuestions) + +3. **Tool Selection**: + - The `get_tool_to_use` method in `Session` converts the session exchanges to a format the LLM can understand + - It calls the `ToolUseAgent.invoke()` method to get the next tool to use + - The LLM decides which tool to use based on the conversation history and available tools + - The selected tool and its parameters are returned + +4. **Tool Execution**: + - The `invoke_tool` method in `Session` executes the selected tool with the provided parameters + - The result is added to the session as a new exchange + - An action node is created to track the tool use and its result + +5. **Termination**: + - The loop continues until a terminating tool is selected (AttemptCompletion or AskFollowupQuestions) + - When a terminating tool is selected, the loop breaks and control is returned to the caller + +## Code Flow + +Here's the sequence of function calls that happen during the agent loop: + +1. `SessionService.tool_use_agentic()` - Entry point for the agent loop +2. `SessionService.agent_loop()` - Main loop that repeatedly selects and executes tools +3. `Session.get_tool_to_use()` - Determines the next tool to use +4. `ToolUseAgent.invoke()` - Uses an LLM to decide which tool to use +5. `Session.invoke_tool()` - Executes the selected tool +6.
