Computer use tool is not implemented yet.

Error message

Computer use tool is not implemented yet.

What it means

Raised by configure_computer_use_tool(), which is a declared static method but unconditionally raises NotImplementedError. The Responses Agent exposes the method signature for API parity, but the computer-use tool is not yet wired up. This is intentional: callers get a clear signal rather than silent behavior.

Solutions

1. Do not call configure_computer_use_tool(); it is not implemented in this version.
2. Remove the computer-use tool from your tool list until the feature ships.
3. Check the semantic_kernel changelog/release notes for when computer-use support lands.
4. If you need computer use now, call the OpenAI Responses API directly outside the agent abstraction.

Example fix

// before
tools = [OpenAIResponsesAgent.configure_computer_use_tool()]

// after
tools = []  # computer use unavailable; omit it

# There is no valid call; guard against invoking it at all
import semantic_kernel.agents.open_ai.openai_responses_agent as m
assert not hasattr(m.OpenAIResponsesAgent, 'configure_computer_use_tool') or True  # informational

def computer_use_available() -> bool:
    return False  # not implemented in current version

try:
    tool = OpenAIResponsesAgent.configure_computer_use_tool()
except NotImplementedError:
    tool = None  # feature not shipped; skip computer use

When it happens

Trigger: Any call to OpenAIResponsesAgent.configure_computer_use_tool(). There is no input that succeeds — the method body is solely `raise NotImplementedError(...)`.

Common situations: Copy-pasting tool-configuration code from an OpenAI Assistants/Responses example that includes computer use, or enumerating available tools programmatically and invoking each configurator. Also hit when following docs that preview the API surface.
