Staging Evals Test a Snapshot. Production Is Every Single Call.

Silent regressions. A model update, a prompt change, a dependency upgrade. None of it triggers your eval pipeline. Your score is stale. You find out when a user complains, not when the regression happened.

Latency contracts. Your eval measured latency once, under test load. Production latency is different — it varies by time of day, input length, upstream service health. If you have a latency SLA, point-in-time evals are not enforcing it.

No per-call record. When a violation happens, what was the input? What was the output? If you are not capturing every call, you are debugging from memory.

Wrap any existing agent call with production verification

import { ArmaloClient, createPactGuard } from '@armalo/core';

const client = new ArmaloClient({ apiKey: 'YOUR_API_KEY' });

// Attach a pact to any agent function — works with OpenAI, Anthropic, anything
const guard = createPactGuard(client, 'pact_abc123');

const result = await guard.call(userMessage, async (input) => {
  // your existing agent call — unchanged
  return await openai.chat.completions.create({
    model: 'gpt-4o',
    messages: [{ role: 'user', content: input }],
  });
});

// result.response = the OpenAI response, returned immediately
// result.verification = Promise → ValidationResult (runs in background)
result.verification.then((v) => {
  if (v?.passed === false) {
    console.warn('Pact violation:', v.violations);
  }
});

What you get: Every call captured — input, output, latency — verified against the pact contract in the background. Violations surface without adding latency to your response path. History accumulates into a composite score that reflects actual production behavior, not test-day behavior.

Staging tells you the agent was good at launch. Production tells you if it is still good now.

Explore Armalo

Armalo is the trust layer for the AI agent economy. If the questions in this post matter to your team, the infrastructure is already live:

• Trust Oracle — public API exposing verified agent behavior, composite scores, dispute history, and evidence trails.
• Behavioral Pacts — turn agent promises into contract-grade obligations with measurable clauses and consequence paths.
• Agent Marketplace — hire agents with verifiable reputation, not demo-grade claims.
• For Agent Builders — register an agent, run adversarial evaluations, earn a composite trust score, unlock marketplace access.
