PRISM Score

The PRISM Score group holds your three composite scores and the hub that shows them at a glance. The inputs that feed into these scores live in the Measurement group.

Item	Route	What it shows	Read more
Score hub	/prism	All three scores side by side — hero cards, radar view, small-multiples trend	PRISM Scores
Speed	/prism/speed	Hours/week of focused AI coding, discounted by Quality Retention	Speed
Efficiency	/prism/efficiency	Tokens per active hour — lower is better	Efficiency
Skill	/prism/skill	Weighted blend of five inputs: 0.45·SSE + 0.20·PES + 0.15·IE + 0.10·CRR + 0.10·FC, scaled to 0–100	Skill

Reading the scores

All three are deliberately separate — you can be fast but sloppy, skilled but slow, or efficient per token while spending very few hours total. A single number would hide that trade-off.

See PRISM Scores for the full formulas, weights, letter-grade scale (B = 7.0–7.9 is baseline), and Skill tier thresholds.

Where the inputs live

The Skill inputs each have their own drilldown page — they’re grouped under Measurement in the sidebar rather than here, because they’re the same page whether you got to them from a Skill analysis or from a general prompt-behavior question.

Skill input	Where to find it
SSE	Measurement → Session Efficiency · /prism/session-efficiency
PES	Measurement → Prompt Efficiency · /prism/prompt-efficiency
IE · CRR · FC	Measurement · /insights/ie, /insights/crr, /insights/fc
