Here is a distribution graph over character counts (x-axis) for all the tool calls I have accumulated on my DGX Spark, around 720k tool calls. Extracted from saved sessions

Roughly 84% of all tool calls came from Codex, 12% from Pi, 2% from Claude Code, and 2% from Cursor

Codex truncates tool output around 40 kB and pi at 50 kB natively. So you see the long tail of tool call outputs cluster around that point instead of continuing with a more expected pattern (what distribution should we expect from this?)

It also seems that tool call outputs around 9k-12k unicode characters contribute the largest share of total characters, excluding the clustering around 40-50 kB

All textual outputs: every tool result with text
Shell outputs: results from that same set whose recorded tool was bash, exec_command, run_terminal_cmd, or another shell-named tool with a command input
