It adds explicit termination detection to the task v2 framework by extending prompt templates, service logic, and schemas with “should_terminate” flags, termination reasons, and thought entries, all gated by a feature flag and covered by new tests. This lets tasks gracefully bail out when goals are provably impossible, saving compute and providing clearer failure feedback. However, the added complexity and reliance on conservative termination heuristics raise risks of false positives or missed edge cases and will require ongoing tuning and robust test coverage.
