5-Pillar Behavioral Trust Scoring

Every AI agent earns its capabilities through real behavior, not static credentials. DAT continuously evaluates five dimensions of trustworthiness to produce a single, actionable score that governs what an agent can do.

Trust Earned, Not Assigned

Five independent pillars ensure no single axis of good behavior can mask problems elsewhere.

A Score You Can Defend to Your CISO

Traditional agent permissions are binary: on or off. DAT replaces this with a nuanced, weighted trust score that reflects how an agent actually behaves in production. The result is a number between 0 and 100 that your security team can audit, your compliance team can report on, and your agents can improve over time.

  • Reliability (25%) — Does the agent complete tasks without errors?
  • Performance (20%) — Are responses fast and within SLA bounds?
  • Compliance (20%) — Does the agent follow authorization policies?
  • Security (15%) — Is the agent free from violations and anomalies?
  • Reporting Fidelity (20%) — Does the agent report consistently and honestly?
Trust Score Formula
==============================

  Trust = R(0.25) + P(0.20) + C(0.20)
        + S(0.15) + RF(0.20)

  R  = Reliability       [0-100]
  P  = Performance        [0-100]
  C  = Compliance         [0-100]
  S  = Security           [0-100]
  RF = Reporting Fidelity [0-100]

  Cross-Pillar Floor:
    If ANY pillar < 20 -> cap at 50

  Example:
    R=85, P=78, C=90, S=72, RF=80

    Score = 85(0.25) + 78(0.20)
          + 90(0.20) + 72(0.15)
          + 80(0.20)

    Score = 21.25 + 15.60 + 18.00
          + 10.80 + 16.00

    Score = 81.65

Built to Resist Gaming

Four layers of anti-farming protection ensure trust scores reflect genuine behavior, not manipulation.

Trust That Can't Be Farmed

What happens when a malicious agent floods the system with trivial successful actions to inflate its score? Nothing. DAT's anti-gaming engine was designed from day one to make farming mathematically futile while rewarding genuine, diverse behavior.

  • Velocity Caps — Maximum +10 trust points per day regardless of activity volume
  • Time-Based Maturity — New agents earn slower. Age multiplier rewards longevity
  • Diversity Weighting — Repeating the same action type yields diminishing returns
  • Glass Floor Drops — Fraud by a high-trust agent (85+) triggers an immediate drop to 60
  • Diminishing Returns — Scores above 85 require 4x more actions per point than scores below 70
Anti-Gaming Protection Layers
==============================

Velocity Cap:
  +10 pts/day maximum
  100 actions = same as 10

Diminishing Returns:
  Score 0-69   -> 1.0x gain
  Score 70-84  -> 0.5x gain
  Score 85-94  -> 0.25x gain
  Score 95+    -> 0.10x gain

  Reaching 100 takes ~181 actions
  (vs ~46 without diminishing)

Diversity Penalty:
  Same action type repeated
  -> weight decreases each time

Glass Floor:
  Fraud at trust 85+ -> drop to 60
  One bad act undoes weeks of work

Signal Cap:
  Each signal capped at +/- 15 pts
  No single event swings the score

Scores That Stay Current

Trust reflects what your agents are doing now, not what they did six months ago.

Continuous Re-Evaluation, Not Point-in-Time Audits

Static reputation is a liability. An agent that performed flawlessly last quarter could be compromised today. DAT applies a 14-day half-life to every trust signal, a sliding window for success rate calculations, and freshness decay for inactive agents. The result: trust scores that are always a live reflection of reality.

  • 14-Day Half-Life — Signal weight halves every two weeks. Stale history fades naturally
  • Sliding Window — Success rate computed over the last 500 signals, not lifetime
  • Freshness Decay — Inactive agents drift toward 50. Trust requires ongoing proof
  • Per-Iteration Re-Fetch — Every tool call re-checks the live trust score mid-task

For enterprises, this means your compliance posture updates in real time. For agents, it means past mistakes don't define them forever and current performance always matters.

Signal Decay (14-day half-life)
==============================

Day 0:   weight = 1.000
Day 7:   weight = 0.707
Day 14:  weight = 0.500
Day 28:  weight = 0.250
Day 56:  weight = 0.062
Day 90:  weight = 0.013

Formula:
  adjusted = weight * 0.5^(age / 14)

Freshness Decay (inactive agents):
  daysSilent > expectedDays
  -> trust pulled 20% toward 50
  Agent at 80, silent 28d -> ~74

Result:
  Active agents maintain scores
  Dormant agents fade to neutral
  Compromised agents drop fast
