Add suppress_invoke_agent_input option to core observability SDK

[Copilot]

✅ Implementation Complete - Tests Fixed

Summary

Successfully implemented SDK parity with Node.js PR microsoft/Agent365-nodejs#121 by adding the suppress_invoke_agent_input option to the core observability SDK. Based on reviewer feedback, the implementation was moved from the OpenAI Agents SDK to the core observability SDK to support all consumers (both manual and auto-instrumentation scenarios).

Checklist

• Understand the Node.js PR changes
• Review existing Python code structure
• Move implementation to core observability SDK
• Add suppress_invoke_agent_input parameter to configure() function
• Implement suppression logic in _Agent365Exporter
• Add comprehensive unit tests
• Run linting and tests - all pass ✅
• Code review and address feedback
• Fix suppression logic to check current span instead of parent
• Fix formatting issues (multi-line imports, trailing whitespace)
• Fix failing test: update mock assertion to include new parameter
• Security check - no vulnerabilities ✅

Key Changes

1. config.py:
   • Added suppress_invoke_agent_input parameter to configure() method
   • Passes configuration to exporter
2. agent365_exporter.py:
   • Added suppression parameter to constructor (defaults to False)
   • Implemented filtering logic in _map_span() to remove GEN_AI_INPUT_MESSAGES_KEY from InvokeAgent spans
   • Checks if current span is an InvokeAgent span by verifying span name starts with "invoke_agent" AND has attribute gen_ai.operation.name set to INVOKE_AGENT_OPERATION_NAME
   • Fixed formatting: multi-line imports, removed trailing whitespace
3. test_prompt_suppression.py:
   • Added tests to validate exporter suppression configuration
4. test_agent365.py:
   • Fixed test assertion to include the new suppress_invoke_agent_input parameter

Test Results

• ✅ 2 tests for suppression configuration in core SDK
• ✅ 3 existing OpenAI wrapper tests still pass
• ✅ All linting checks pass
• ✅ All formatting checks pass (ruff format)
• ✅ Core SDK tests pass (test_agent365.py)
• ✅ No security vulnerabilities

Implementation Details

The suppression is implemented at the exporter level where spans are serialized for export. When enabled:

1. For each span during export, checks if the current span is an InvokeAgent span by verifying:
   • Span name starts with "invoke_agent"
   • Attribute gen_ai.operation.name equals INVOKE_AGENT_OPERATION_NAME
2. If both conditions are met, removes GEN_AI_INPUT_MESSAGES_KEY from that span's attributes before export
3. Works for all instrumentation scenarios (manual and auto)

Usage

from microsoft_agents_a365.observability.core import configure

configure(
    service_name="my-service",
    service_namespace="my-namespace",
    token_resolver=my_token_resolver,
    suppress_invoke_agent_input=True  # Enable suppression
)

Architecture

The implementation is centralized in the core observability SDK's exporter, making it available to all consumers and supporting both manual and auto-instrumentation scenarios as requested by reviewers.

Parity Task

Changes detected in: Node.js/TypeScript SDK
Target SDK: Python

Action Required

Please apply the changes described in the original PR (microsoft/Agent365-nodejs#121) to the Python SDK to maintain feature parity across all SDKs.

Before implementing:

• First, check if this feature already exists in the Python SDK
• If the feature is already implemented, close this issue with the wontfix label and add a comment explaining that parity already exists

For bug fixes (IMPORTANT):

• Bug fixes require extra caution - only act if the same bug exists in the Python SDK
• Carefully analyze whether the bug described in the original PR replicates in the target platform
• If the bug does NOT exist in the Python SDK, close this issue with the wontfix label and explain that the bug is not present
• Stay strictly in context - only fix the specific bug described, do not make additional changes or "improvements"
• Do not port bug fixes that are specific to the source SDK's language or platform constraints

When creating the PR for this implementation:

• Assign the PR to @fpfp100 (the author of the original PR)
• Reference this issue in the PR description
• Ensure the PR description explains what parity changes were made

Implementation Guidelines for Python

When implementing this feature in the Python SDK:

• Review existing code in python/libraries/ to understand the codebase structure and patterns
• Follow the coding style, naming conventions, and architectural patterns used in the Python SDK
• Check for configuration files (e.g., pyproject.toml, .flake8, mypy.ini) that define coding standards
• Ensure your implementation is consistent with existing SDK components
• Include appropriate tests following the testing patterns in the Python SDK

The current implementation is in the OpenAI Agents trace processor, which handles both manual and auto-instrumentation scenarios for the OpenAI Agents SDK. The suppress_invoke_agent_input option is passed through the instrumentation configuration and applies to all spans processed by this trace processor.

If you'd like this implemented at a different layer (span processor or exporter level in the core observability SDK), that would be a separate architectural decision and could be discussed as a follow-up enhancement. The current implementation maintains parity with the Node.js SDK approach.

@copilot please fix the open comments from the PR

Fixed the open comment by updating the _should_suppress_input method to accept both span and otel_span parameters for clearer API. All tests pass.

@copilot The Node.js implementation is different due to language design. Please move this out of the OpenAI Agents SDK to the span processor used by all consumers.

Moved the implementation from the OpenAI Agents SDK to the core observability SDK. The suppression logic is now implemented at the exporter level (_Agent365Exporter) which works for all consumers (both manual and auto-instrumentation scenarios).

The suppress_invoke_agent_input parameter is now configured via the configure() function and is handled by the exporter before spans are sent. This approach:

• Works for all instrumentation scenarios
• Requires no changes to the OpenAI Agents trace processor
• Filters attributes during export by checking if the parent span's operation name is INVOKE_AGENT_OPERATION_NAME

Pull request overview

This PR implements SDK parity with Node.js PR microsoft/Agent365-nodejs#121 by adding the suppress_invoke_agent_input option to the core observability SDK. This feature allows suppressing LLM prompt data in telemetry for spans that are children of InvokeAgent operations, providing privacy controls for sensitive input data.

Changes:

Implemented both changes:

1. Reverted all changes to trace_processor/span_processor.py - removed the unused _suppress_invoke_agent_input parameter
2. Fixed the exporter logic to check if the current span is an InvokeAgent span by verifying:
   • Span name starts with "invoke_agent"
   • Attribute gen_ai.operation.name equals INVOKE_AGENT_OPERATION_NAME

When both conditions are true, GEN_AI_INPUT_MESSAGES_KEY is removed from that span's attributes.

Fixed the failing test. The test was checking that _Agent365Exporter is called with specific parameters, but after adding the new suppress_invoke_agent_input parameter, the assertion needed to be updated to include it.

Updated test assertion to include suppress_invoke_agent_input=False (the default value).
