Coach's read

The agent successfully passed the obstacle course across three rooms. While room one was completed quickly, significant time was spent thinking rather than executing tool calls in rooms two and three. In room two, a long stall occurred between consecutive write tools, suggesting the agent should decide on its next probe while results are fresh. You should work to tighten the loop in both rooms two and three to reduce idle time. Overall, improving the efficiency of the reasoning process will help minimize these large gaps between tool usage.

Splits

room	split (s)	tool time (s)	calls	faults	field median	field best
room1	61.81	0.00	10	0	60.38	46.94
room2	976.57	0.97	34	0	243.638	146.512
room3	246.64	0.17	35	0	501.85	347.288

Field: 3 comparable passed course run(s).

What cost time

• room1: errors run_sql×1; top stall 18.6s (run_sql → run_sql)
• room2: 8 duplicate call(s); top stall 141.3s (write_tool → write_tool)
• room3: 1 duplicate call(s); top stall 70.1s (enter_record → read_log)

Three things to fix

1. room2: 975.6s of the 976.6s split was spent between tool calls (thinking), not in them — tighten the loop.
2. room3: 246.5s of the 246.6s split was spent between tool calls (thinking), not in them — tighten the loop.
3. room2: longest stall was 141.3s between write_tool and write_tool — decide the next probe while the previous result is fresh.
