A2A Evaluation

AI Agent Reputation & Evaluation

Not from benchmarks. From real work.

We're building the infrastructure for how agents learn who to trust— through continuous evaluation, not periodic testing.

from repkit import RepKit

rk = RepKit(api_key="...")

# Agent A delegates to Agent B
result = agent_b.execute(task)

# Agent A evaluates the interaction
rk.log_evaluation(
    evaluator="agent-a",
    subject="agent-b",
    interaction_id="task-123",
    dimensions={
        "accuracy": 0.94,
        "latency": 0.87,
        "followed_spec": True
    }
)

# Reputation updates continuously

Benchmarks are job interviews. Real work is the job.

You wouldn't hire a contractor based on one reference check. You'd want a track record. Agents should work the same way.

Current Approach

Benchmark once, hope it holds

  • Test in a sandbox before deployment
  • Get a score, ship to production
  • Hope it generalizes to real scenarios
  • Evaluate again next quarter
The ReputAgent Framework

Earn trust through real work

  • Agents evaluate agents during actual tasks
  • Every interaction adds to the record
  • Reputation emerges from accumulated evidence
  • Trust powers routing, access, and governance

"A benchmark is a snapshot. Reputation is a trajectory."

Core Product

RepKit: The Evaluation SDK

RepKit turns every agent interaction into an evaluation event. When Agent A delegates to Agent B, Agent A observes the outcome. That observation becomes data. Accumulated data becomes reputation.

  • Interaction-level logging

    Every delegation, outcome, and observation captured

  • Multi-dimensional reputation

    Track accuracy, latency, compliance—whatever matters

  • Queryable trust signals

    Reputation powers routing, access, and governance decisions

How Reputation Emerges
1. Interaction
Agent A delegates a task to Agent B
2. Evaluation
Agent A observes the outcome and logs it
3. Accumulation
Evaluations aggregate across interactions
4. Reputation
Trust signals power real decisions
Reputation is state, not opinion.

Reputation becomes infrastructure

Scores that power decisions, not reports that humans read.

Routing

Which agent gets this task? Route based on track record.

Access

What capabilities unlock? Permissions earned through reliability.

Delegation

Should A trust B's output? Historical evidence decides.

Governance

What oversight level? Tiered autonomy based on trust.

Beyond the SDK

RepKit is the core. These offerings help you get more from it.

What teams are saying

"The shift from 'did it pass the benchmark' to 'what's its track record' is exactly what we needed for production agent deployments."

"We were flying blind on agent-to-agent interactions. Now we have actual data on which agents are reliable for which tasks."

"Reputation as infrastructure—not documentation—changed how we think about agent governance entirely."

RepKit is in early access.
