Cognitive Ergonomics (candidate lens)

The five AM axes all protect the work: Verification checks the output, Context hygiene checks what the model sees, Autonomy/leash sets how much you delegate, Learning/compounding checks whether the system improves, Cost & governance checks whether it stays in bounds. None of them protect the operator.

Cognitive ergonomics is the candidate sixth lens: how well a person sustains the attention and judgment that supervising agents demands. As agents get cheaper and more parallel, the human’s attention — not the model — becomes the bottleneck, and the failure modes that human-factors research documented decades ago reappear unchanged.


Three findings from the research wiki explain why supervising agents is cognitively harder than writing code, and why none of the existing five axes captures it:

  • The supervision paradox (Bainbridge, 1983) — automation removes the easy work and leaves the human the hard, rare, high-stakes judgments, while eroding the vigilance needed to make them. A developer can be L5 on the Spine and still fail here.
  • Attention residue (Leroy, 2009) — hopping between concurrent agent sessions leaves part of your attention stuck on the last one, degrading judgment on the next. Orchestration is task-switching by design.
  • Flow and its fragility (Csikszentmihalyi, 1990) — high-quality work needs contiguous focus, which interruptions shatter instantly. Interrupt-driven orchestration is hostile to it unless deliberately managed.

The distinctive claim of this lens is that its signals already exist as operational data — the AIOS workspace toolkit computes them from your own session activity, locally, over active_hours (wall-clock time split into work blocks at idle gaps):

SignalWhat it measures
focus_block_avg_minMean length of an uninterrupted work block — a flow-condition proxy
context_switch_rateProject changes between consecutive prompts, per active hour — residue from switching what
interrupts_per_hourPrompts that hop to a different session, per active hour — residue from switching which agent
concurrent_sessions_peakMax distinct sessions active in a 5-minute window — supervision load

Today these produce a one-line reading of your attention pattern (deep-work-leaning · orchestration-heavy · mixed · no activity), plus a shadow band (04, vs your own baseline) in local reports and — when you push — in the Team Brain beside AM. The band is a coarse mirror, not a calibrated maturity score: we can measure the pattern; we cannot yet say which pattern is “more mature.”


Why this is a candidate and not an axis: a maturity axis needs bands — immature → mature — and we do not yet have the evidence to draw them honestly. The hard question is that the “mature” pattern is not obvious. A high concurrent_sessions_peak might indicate skilled L5 orchestration or attention-shredding overreach; a long focus_block_avg_min might be deep engagement or a failure to delegate. The signal is real; its interpretation is not settled.

Calibrating the bands would require:

  • Baseline windows — enough per-operator history to separate a normal day from a degraded one, rather than judging against an absolute threshold.
  • A decisions corpus — correlating attention patterns with downstream outcomes (were the judgments made under high interrupts_per_hour worse?), so bands map to quality, not just to a preferred work style.
  • Guarding against a bad incentive. A naive band (“more focus = more mature”) could penalize legitimate high-orchestration work. The lens must not become a productivity-surveillance metric; it is a mirror for the operator, tier-admin by default and computed locally.

Until that work is done, the five-axis model stands unchanged and this lens stays explicitly a research proposal.
