Agent sessions charted on per-user lanes, then compressed into metrics a lead can act on: output per prompt, leverage, and tool health.
The work moved. An engineer's day is now prompts, parallel agent runs, and review. Commit counts and hours online describe the old job, not this one.
One board shows it. Every agent session lands on that engineer's lane: solid while the agent runs, dotted while they wait, striped while subagents work in parallel.
Rest is not penalized. Idle over 10 minutes counts as a break, not as wait. The metrics measure effectiveness in the zone, not time at the desk.
Compare, then coach. Select any set of engineers and see the same metrics side by side. The gap between a 4-minute prompt and a 1-minute prompt is a coaching conversation, not a mystery.
