# 🧠 Agents and Capabilities

## Monologue Agent

### Description

The Monologue Agent utilizes long and short term memory to complete tasks.
Long term memory is stored as a LongTermMemory object and the model uses it to search for examples from the past.
Short term memory is stored as a Monologue object and the model can condense it as necessary.

### Methods

| Method          | Description                                                                                                                                   |
| --------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| `__init__`      | Initializes the agent with a long term memory, and an internal monologue                                                                      |
| `_add_event`    | Appends events to the monologue of the agent and condenses with summary automatically if the monologue is too long                            |
| `_initialize`   | Utilizes the `INITIAL_THOUGHTS` list to give the agent a context for its capabilities and how to navigate the `/workspace`                    |
| `step`          | Modifies the current state by adding the most recent actions and observations, then prompts the model to think about its next action to take. |
| `search_memory` | Uses `VectorIndexRetriever` to find related memories within the long term memory.                                                             |

## Planner Agent

### Description

The planner agent utilizes a special prompting strategy to create long term plans for solving problems.
The agent is given its previous action-observation pairs, current task, and hint based on last action taken at every step.

`CmdRunAction`,
`CmdKillAction`,
`BrowseURLAction`,
`GithubPushAction`,
`FileReadAction`,
`FileWriteAction`,
`AgentRecallAction`,
`AgentThinkAction`,
`AgentFinishAction`,
`AgentSummarizeAction`,
`AddTaskAction`,
`ModifyTaskAction`,

### Observations

`Observation`,
`NullObservation`,
`CmdOutputObservation`,
`FileReadObservation`,
`AgentRecallObservation`,
`BrowserOutputObservation`

### Methods

| Method          | Description                                                                                                                                                                               |
| --------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `__init__`      | Initializes an agent with `llm`                                                                                                                                                           |
| `step`          | Checks to see if current step is completed, returns `AgentFinishAction` if True. Otherwise, creates a plan prompt and sends to model for inference, adding the result as the next action. |
| `search_memory` | Not yet implemented                                                                                                                                                                       |

## CodeAct Agent

### Description

The Code Act Agent is a minimalist agent. The agent works by passing the model a list of action-observation pairs and prompting the model to take the next step.

### Actions

`Action`,
`CmdRunAction`,
`AgentEchoAction`,
`AgentFinishAction`,

### Observations

`CmdOutputObservation`,
`AgentMessageObservation`,

### Methods

| Method          | Description                                                                                                                                                                                                                                             |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `__init__`      | Initializes an agent with `llm` and a list of messages `List[Mapping[str, str]]`                                                                                                                                                                        |
| `step`          | First, gets messages from state and then compiles them into a list for context. Next, pass the context list with the prompt to get the next command to execute. Finally, Execute command if valid, else return `AgentEchoAction(INVALID_INPUT_MESSAGE)` |
| `search_memory` | Not yet implemented                                                                                                                                                                                                                                     |
