Teacher Assistant
The assistant queries the current grading context, shows a trace of planning and tool use, and leaves each risk and next action for teacher confirmation.

The trace and final answer share one demo, so teachers can inspect which context was used before taking action.
The visible trace summarizes planning, tool use, and GradeOS data retrieval while the answer is assembled.

Assistant boundaries
The assistant retrieves accessible batch, result, and class information; marketing examples are never treated as real classroom data.
Planning, retrieval, and tool use appear as a readable summary so teachers can see where the answer came from.
The assistant points to risk and the next review priority. Correction, confirmation, and publication remain teacher actions.
The answer is useful because the reasoning and classroom evidence remain close.
