The Framework

Five dimensions of Human-AI proficiency

Inspired by DORA Metrics and Microsoft's SPACE framework. Behavioral signals from your logs — no surveys, no guesswork.

C

Context

How effectively you engineer context for the AI

CLAUDE.md usage, memory writes, cache hit rate

R

Reach

How broadly you leverage available capabilities

Tool diversity, subagent usage, skill adoption

A

Autonomy

How independently the agent works for you

Message ratio, interruption rate, delegation

F

Flow

How consistently you maintain a coding rhythm

Streak length, daily consistency, active days

T

Throughput

How much output you get for your investment

Cost efficiency, output volume, error rate

Scoring: Each dimension is 0–100. Autonomy weighs 25%, Context/Reach/Throughput 20% each, Flow 15%.
