Model & Harness Message Mix
Counts of message metadata by harness, session, role, direction, and modality. Bodies are not captured. I02 accounts disjoint tokens. I08 accounts settled action failure. Neither number is recomputed on this page.
All-time counts — window_from/window_to label the snapshot but do not filter.
Modality Mix by Harness: Stacked horizontal bars display the distribution of messages exchanged with each client harness:
Inbound Messages (Cyan)
User prompts, task handoffs, and tool results entering the agent harness runtime.
Outbound Messages (Emerald)
Assistant completions, reasoning summaries, and tool invocation requests initiated by the agent.
Modality Types
Tracks plain text, tool_use commands, tool_result returns, and structured protocol payloads.
Zero Content Capture
Strict privacy invariant: only metadata headers, directions, and modalities are logged. Content bodies remain uninspected.
Key message telemetry dimensions and capability indicators:
Total Messages
Count of distinct message exchanges in observation window
Active Harnesses
Distinct agent client runtimes (Claude, Codex, Grok, etc.)
I02 Model Tokens
Disjoint token accounting without double-counting reasoning
I08 Action Failure
Settled tool call failure rate; unsettled turns excluded from success
I02 model.tokens.direct
Disjoint sums of input_uncached, cache_write, cache_read, and output. Reasoning is included in output and is not part of the disjoint sum. Cache-read ratio of sums and mean of ratios are separate measures.
I08 harness.action_failure
Failed divided by settled terminal actions. Unsettled rows, where failed is null, are counted apart and are never treated as succeeded. This view does not store tool arguments.
Modality mix by harness
Widths are message_count shares. They are not tokens and not failure rates.
