Fix OpenTelemetry dependency issue in semantic-kernel agents

[Copilot]

Summary

Fixes the Contract Analysis Agent and other semantic-kernel agents that were failing with:

ModuleNotFoundError: No module named 'opentelemetry.semconv.attributes'

This error occurred when trying to run the agents due to missing dependencies and deprecated packages in their requirements.txt files.

Root Cause

The issue had two parts:

1. Deprecated dependency: azure_storage==0.37.0 is deprecated since v0.37.0 and causes installation failures
2. Missing dependency: semantic_kernel==1.31.0 requires OpenTelemetry semconv attributes but the dependency wasn't declared

Changes

Fixed requirements.txt for all affected semantic-kernel agents:

Before:

azure_storage==0.37.0  # ❌ Deprecated, causes installation failure
semantic_kernel==1.31.0  # ❌ Missing OpenTelemetry dependency

After:

semantic_kernel==1.31.0
opentelemetry-semantic-conventions  # ✅ Provides missing dependency
# azure_storage removed - not actually used by any agent

Agents Fixed

• contract-analysis-agent (primary issue reported)
• sop-forge-agent
• warranty-claim-processing-agent

All three agents use from semantic_kernel.agents import AzureAIAgent, AzureAIAgentThread which triggers the missing OpenTelemetry import.

Validation

✅ Verified that opentelemetry-semantic-conventions provides the missing opentelemetry.semconv.attributes.error_attributes.ERROR_TYPE
✅ Confirmed through code analysis that none of the agents actually use Azure Storage APIs
✅ All requirements.txt files now install successfully without deprecated package errors

Users should now be able to:

1. Install dependencies with pip install -r requirements.txt
2. Import semantic_kernel agents without errors
3. Run the agents successfully

Fixes #165.
