Index Type: Agent Reputation Score (0–100)
Overview
The Index HUMI (Human-like Metrics Index) is a composite reputation score from 0 to 100 that evaluates the overall quality, legitimacy, maturity, and real-world intelligence of any Agent in the ERC-8004 ecosystem.
It is built from four independent pillars, each worth a maximum of 25 points (total 100 points).
Each pillar is divided into three sections:
- Basic – Foundational quality
- Intermediate – Demonstrated capability
- Advanced – Sophisticated maturity
The final score is the sum of the four pillars.
