Tool Call Managers

Tool Call Managers execute local code in response to AI-dispatched tool calls. The AI sends a structured call; the manager runs the corresponding logic and returns the result back to the agent.

All Tool Call Managers are discovered automatically by Agent Behaviour via GetComponentsInChildren — no registration needed.

Function Call Manager

Component: AI Dev Kit / Agent / Function Call Manager

Binds C# methods to AI-callable functions. Supports void, UniTask, and UniTask<T> return types, CancellationToken parameters, and full JSON argument binding.

public class FunctionCallManager : ToolCallManagerBase<FunctionCall, FunctionOutput>, IFunctionExecutor

Fields:

Field	Type	Description
functions	List<FunctionDescriptor>	Registered C# method bindings. Configure via the Inspector.

Add a function binding in the Inspector under Add Function, then select the target component and method name. The method signature is inspected at runtime to bind JSON arguments automatically.

Shell Command Call Manager

Component: AI Dev Kit / Agent / Shell Command Call Manager

Executes local shell commands on behalf of the AI. Only whitelisted commands (registered via the Shell Command Catalog) can be executed.

public class ShellCommandCallManager : ToolCallManagerBase<LocalShellCall, LocalShellOutput>, ILocalShellExecutor

Fields:

Field	Type	Description
registeredCommandKeys	string[]	Whitelist of command keys the AI is permitted to execute.
logOutputs	bool	Log stdout/stderr to the Unity console.

Security note: Always restrict registeredCommandKeys to the minimum set of commands your application requires.

Computer Use Call Manager

Component: AI Dev Kit / Agent / Computer Use Call Manager

Enables the AI to control the device — simulating mouse clicks, keyboard input, drag operations, scrolling, and screenshots.

public class ComputerUseCallManager : ToolCallManagerBase<ComputerUseCall, ComputerUseOutput>, IComputerUseExecutor

Fields:

Field	Type	Description
waitTimeInSeconds	float	Delay between consecutive computer use actions.
onInputEventReceived	UnityEvent<ComputerUseAction>	Fires for each input action so you can implement custom action handling.

Implement IComputerUseActionHandler to provide the actual platform-specific input simulation.

---

Custom Tool Call Manager

Component: AI Dev Kit / Agent / Custom Tool Call Manager

A base component for implementing completely custom AI-callable tools with arbitrary logic.

public abstract class CustomToolCallManager : MonoBehaviour, ICustomToolExecutor

Subclass this component, override ExecuteAsync, and add your component to the Agent's GameObject. The agent discovers it automatically.
