Why it matters
Tereza Tížková’s publisher notes describe Factory Missions as an orchestrator assigning sequential workers and independent validators. The orchestrator defines completion criteria before implementation; validators combine code checks with interaction through a running application. Deferred loading of tool specifications reduces context overhead but does not define authorization. The useful design is a separation of implementation and validation, while the talk’s cost savings and long-run examples lack enough benchmark detail to establish general reliability.
My takeaway: Define the intended outcome before starting an agent loop and keep its acceptance criteria outside the worker’s control. Test real application behavior as well as lint, types and unit tests. Evaluate model routing with failures and retries included, and enforce permissions separately from which tool descriptions enter context.
