+# Bug Fixes Implementation Summary
+
+## Successfully Fixed 3 Critical Bugs in AgentOps Codebase
+
+### Bug #1: ✅ FIXED - Bare Exception Handling (Security & Reliability Issue)
+
+**Files Modified:**
+- `agentops/helpers/system.py` (8 functions fixed)
+- `agentops/helpers/serialization.py` (1 function fixed)
+
+**Changes Made:**
+- Replaced all bare `except:` clauses with `except Exception as e:`
+- Added proper logging of caught exceptions for debugging
+- Preserved functionality while preventing masking of critical system exceptions
+
+**Impact:**
+- ✅ No longer catches `SystemExit`, `KeyboardInterrupt`, and other critical system exceptions
+- ✅ Improved debugging capability with proper error logging
+- ✅ Enhanced security by not hiding security-related exceptions
+- ✅ Follows Python best practices for exception handling
+
+**Example Fix:**
+```python
+# Before (dangerous)
+except:
+    return {}
+
+# After (safe)
+except Exception as e:
+    logger.debug(f"Error getting SDK details: {e}")
+    return {}
+```
+
+---
+
+### Bug #2: ✅ FIXED - Race Condition in Singleton Client (Concurrency Issue)
+
+**Files Modified:**
+- `agentops/client/client.py`
+
+**Changes Made:**
+- Added `threading.Lock()` class variable for thread safety
+- Implemented double-checked locking pattern in `__new__` method
+- Ensured thread-safe singleton instance creation
+
+**Impact:**
+- ✅ Prevents multiple client instances in multi-threaded environments
+- ✅ Eliminates race conditions during client initialization
+- ✅ Ensures consistent state across threads
+- ✅ Maintains singleton pattern integrity
+
+**Implementation:**
+```python
+class Client:
+    _lock = threading.Lock()  # Class-level lock
+
+    def __new__(cls, *args, **kwargs):
+        # Double-checked locking pattern
+        if cls.__instance is None:
+            with cls._lock:
+                if cls.__instance is None:
+                    cls.__instance = super(Client, cls).__new__(cls)
+                    # Initialize safely within lock
+        return cls.__instance
+```
+
+---
+
+### Bug #3: ✅ FIXED - Resource Leak in Stream Processing (Memory Issue)
+
+**Files Modified:**
+- `agentops/instrumentation/providers/openai/stream_wrapper.py`
+
+**Changes Made:**
+- Added proper context token cleanup in `try/finally` blocks
+- Ensured context tokens are always detached, even during exceptions
+- Added graceful error handling for cleanup operations
+
+**Impact:**
+- ✅ Prevents memory leaks from unreleased context tokens
+- ✅ Eliminates context pollution in OpenTelemetry tracing
+- ✅ Improves long-term performance and stability
+- ✅ Ensures proper resource cleanup under all conditions
+
+**Implementation:**
+```python
+async def __anext__(self):
+    try:
+        # ... stream processing ...
+        return chunk
+    except StopAsyncIteration:
+        try:
+            # Proper span finalization
+            self._span.set_status(Status(StatusCode.OK))
+            self._span.end()
+        finally:
+            # Always detach context token
+            if hasattr(self, '_token') and self._token:
+                try:
+                    context_api.detach(self._token)
+                except Exception:
+                    pass  # Ignore detach errors during cleanup
+        raise
+    except Exception as e:
+        # ... error handling ...
+        finally:
+            # Always cleanup resources
+            if hasattr(self, '_token') and self._token:
+                try:
+                    context_api.detach(self._token)
+                except Exception:
+                    pass
+        raise
+```
+
+---
+
+## Verification
+
+All fixed files have been verified to compile successfully:
+- ✅ `agentops/helpers/system.py`
+- ✅ `agentops/helpers/serialization.py`
+- ✅ `agentops/client/client.py`
+- ✅ `agentops/instrumentation/providers/openai/stream_wrapper.py`
+
+## Impact Assessment
+
+These fixes address:
+
+1. **Security & Reliability**: Proper exception handling prevents masking critical system errors
+2. **Concurrency Safety**: Thread-safe singleton prevents race conditions and state corruption
+3. **Memory Management**: Proper resource cleanup prevents memory leaks and performance degradation
+
+The AgentOps SDK is now more robust, secure, and reliable for production use.
