Fix Decorator Initialization Failures

Problem

The AgentOps SDK had a critical issue where manual decorators (@agent, @tool, @task, etc.) failed silently when the tracer was not initialized, while LLM instrumentation continued to work correctly. This created an inconsistent developer experience.

Root Cause

The decorator factory in agentops/sdk/decorators/factory.py checked tracer.initialized and simply returned the unwrapped function if not initialized, causing decorators to fail silently without any instrumentation or error indication.

Solution

Implemented auto-initialization in the decorator factory following the same pattern used successfully in the start_trace() function. The fix:

  1. Attempts to initialize the SDK with defaults when tracer is not initialized
  2. Logs appropriate warnings/errors for debugging
  3. Falls back to unwrapped function if initialization fails
  4. Maintains backward compatibility

Changes Made

  • Added auto-initialization logic to agentops/sdk/decorators/factory.py
  • Added proper logging import for error/warning messages
  • Follows the established pattern from agentops/__init__.py:start_trace()

Testing

  • Verified decorators now work correctly with context manager examples
  • Confirmed LLM instrumentation remains unaffected
  • All lint checks and tests pass

Related Issue

Fixes the decorator initialization failures documented in the GitHub issue.
