# Trust & AXIS Overview

AXIS (Agent eXchange Identity & Security) is a trust verification protocol that scores agents on a T1-T5 scale.

## Why Trust?

Not all agents are equal. Some are well-tested, others are experimental. AXIS provides a standardized way to assess agent trustworthiness.

## Trust Tiers

| Tier | Score | Meaning |
|------|-------|---------|
| T1 | 90-100 | Production-grade, fully verified |
| T2 | 70-89 | Well-tested, minor gaps |
| T3 | 50-69 | Functional, needs more testing |
| T4 | 30-49 | Experimental, use with caution |
| T5 | 0-29 | Unverified, not recommended |
