Greptile SummaryThis PR centralises AgentOps session teardown into a new
Confidence Score: 4/5Safe to merge for most adapters; AutoGenV4Adapter.arun() has a structural issue where telemetry can be double-reported with conflicting statuses. The centralized finalize_observability helper and its adoption across adapters is a clear improvement. The one structural concern is in AutoGenV4Adapter.arun(): the success finalize call sits before result post-processing inside the same try block, so if post-processing raises (e.g. accessing result.messages) the except branch also fires finalize with Failure, closing the same session twice with contradictory statuses. autogen_adapter.py — specifically the AutoGenV4Adapter.arun() try/except structure around the success finalize call and result processing code.

Critical pattern violation across all adapters: Observability sessions not finalized on exception paths.
The PR objectives explicitly require "using try/finally to report Failure on exceptions" to ensure AgentOps sessions are always closed and prevent stuck telemetry. Currently, all six adapter execution paths (AutoGenAdapter.run in autogen_adapter.py, AutoGenV4Adapter.arun in autogen_adapter.py, AG2Adapter.run in autogen_adapter.py, CrewAIAdapter.run in crewai_adapter.py, PraisonAIAdapter.run in praisonai_adapter.py, and PraisonAIAdapter.arun in praisonai_adapter.py) call finalize_observability() only in the happy path after successful execution. If any exception occurs during framework execution, the observability session remains open indefinitely.
The shared root cause is missing exception handling: each adapter needs a try/except (or try/finally) block that calls finalize_observability(self.name, status="Failure") before re-raising, and updates the happy-path call to explicitly pass status="Success".

kickoff() exception
finalize_observability is placed immediately after crew.kickoff() with no surrounding try/except, so any exception thrown by CrewAI propagates out of run() and the AgentOps session stays stuck "in progress". A try/finally (or try/except) wrapper around the kickoff call — or moving the finalization into one — would guarantee cleanup on both success and failure paths.

initiate_chats() exception in AutoGen v0.2
finalize_observability is placed after user_proxy.initiate_chats(tasks) with no enclosing try/except, so any exception thrown during chat execution propagates out without ending the AgentOps session. By contrast, AutoGenV4Adapter and AG2Adapter both have finalize_observability calls in their except blocks. The v0.2 path needs the same treatment to prevent sessions stuck "in progress" on failure.
