Commands

This page discusses how to register that commands are loaded/unloaded in a callback

Example Agent Response

{
    "task_id": "task uuid here",
    "user_output": "some user output here",
    "commands": [
        {
            "action": "add",
            "cmd": "shell"
        },
        {
            "action": "add",
            "cmd": "jsimport"
        }
    ]
}

Walkthrough

It's a common feature for agents to be able to load new functionality. Even within Mythic, you can create agents that only start off with a base set of commands and more are loaded in later. Using the commands keyword, agents can report back that commands are added ("action": "add") or removed ("action": "remove").

This is easily visible when interacting with an agent. When you start typing a command, you'll see an autocomplete list appear above the command prompt with a list of commands that include what you've typed so far. When you load a new command and register it back with mythic in this way, that new command will also appear in that autocomplete list.
