IToolRegistry

Namespace AgentPrism · Assembly AgentPrism.Abstractions.dll

The registry of tools registered in code.

public interface IToolRegistry

Remarks

Section titled “Remarks”

This registry is one of AgentPrism’s security boundaries. An agent definition can only point to a registered tool by name. Tool code cannot be written from the UI; only a selection is made from registered tools. This keeps anyone with UI access from running code on the server.

Methods

Section titled “Methods”

List()

Section titled “ List()”

Returns the definitions of all registered tools, ordered by name.

IReadOnlyList<ToolDescriptor> List()

Returns

Section titled “Returns”

TryGet(string, out AIFunctionDeclaration?)

Section titled “ TryGet(string, out AIFunctionDeclaration?)”

Fetches the tool with the given name.

bool TryGet(string name, out AIFunctionDeclaration? tool)

Parameters

Section titled “Parameters”

name string

The tool name. Comparison is case-sensitive.

tool AIFunctionDeclaration?

The tool found.

Returns

Section titled “Returns”

bool

true if the tool is registered.

Remarks

Section titled “Remarks”

The result is an AI.AIFunctionDeclaration, not an AI.AIFunction: a client-side tool (AddClientTool) is registered as a declaration-only AIFunctionDeclaration, which is not an AI.AIFunction and cannot be invoked. Every registered tool — server-side or client-side — is an AI.AIFunctionDeclaration, so AIFunctionDeclaration.JsonSchema is always available. Callers pass the result straight to ChatOptions.Tools, which accepts the broader AITool.
