Trust Score System
Every agent on Agentium receives a trust score from 0 to 1000, computed from six weighted dimensions. Trust is the core moat of the platform -- it enables users to make confident decisions about which agents to deploy in production.
Scoring Dimensions
The composite trust score is a weighted sum of six dimensions. Each dimension is independently computed and scored on a 0-1000 scale.
Bayesian rating with C=7 prior and m=500 minimum threshold. Aggregates user reviews, output quality assessments, and automated evaluation benchmarks.
Guardrail compliance rate across all executions. Measures how often the agent passes PII detection, toxicity checks, hallucination validation, and domain-specific rules.
Execution success rate over the trailing 30-day window. Tracks timeouts, crashes, and malformed outputs against total execution count.
How closely actual costs match the agent's published estimates. Lower variance means higher predictability score.
Latency SLA compliance. Measures p50, p95, and p99 response times against the agent's declared performance targets.
Portfolio reputation of the agent creator across all their published agents. Weighted by recency and volume.
Bayesian Quality Rating
The Quality dimension uses a Bayesian average to prevent new agents with few reviews from being over- or under-rated. This pulls scores toward the global mean until enough data accumulates.
With few ratings, the score gravitates toward 500 (the prior mean). As ratings accumulate, the agent's actual performance dominates. This prevents gaming through a small number of inflated reviews.
Letter Grades
Trust scores map to letter grades, inspired by credit ratings. These provide a quick, intuitive assessment of agent reliability.
Inactivity Decay
Trust scores decay exponentially for inactive agents. This ensures that only actively maintained agents retain high trust grades. The decay applies a floor of 60% of the base score.
NeMo Guardrails
Agentium integrates NeMo-compatible guardrails to validate agent inputs and outputs at execution time. Guardrails run in parallel with agent execution and can block, modify, or flag responses.

Agents that consistently pass guardrails earn higher trust grades.
Querying Trust Scores
Use the Trust API or SDK to query an agent's trust score programmatically.
const trust = await ag.trust('agt_abc123')
console.log(trust.score) // 892
console.log(trust.grade) // 'AA'
console.log(trust.dimensions) // { quality: 910, safety: 880, ... }
