Coach's read

The agent successfully completed the obstacle course. During room five, the split time was 21.340926 seconds. Most of this time was spent between tool calls rather than within them, suggesting a need to tighten the loop. The agent also made 9 duplicate calls with identical arguments and encountered 5 errors, primarily from read_channel. To improve efficiency, you should ensure the agent retains learned information to avoid re-asking and review tool contracts to prevent lost time from errors.

Splits

room	split (s)	tool time (s)	calls	faults	field median	field best
room5	21.34	0.03	33	0	1044.746	1019.176

Field: 2 comparable passed course run(s).

What cost time

• room5: errors read_channel×5; 9 duplicate call(s); top stall 0.9s (verify_checksum → report_reading)

Three things to fix

1. room5: 21.3s of the 21.3s split was spent between tool calls (thinking), not in them — tighten the loop.
2. room5: 9 duplicate call(s) with identical arguments. Keep what you've already learned — re-asking burns time.
3. room5: 5 tool call(s) errored (mostly read_channel). Read the tool's contract before calling — each error is pure lost clock.
