operatorstack Run:
yskill run .
Follow each returned operation exactly.
ask_user: ask the user using the host's normal interface.agent_task: perform the task and return schema-valid JSON.run_command: yskill executes it itself; you will not see this kind.
Resume the run after each operation:
yskill resume <run-id> --response response.json --skill .
Do not skip an operation or invent its response. The program bounds the investigation: at least three hypotheses, cheapest-to-disprove first, at most three failed attempts, and completion requires a causal chain.
