TL;DR
Direct answer: "Is This Agent Good?" and "Will This Agent Deliver?" Are Different Questions matters because which score answers which question.
The real problem is conflating eval quality with delivery reliability, not generic uncertainty. Portable history only helps when another system can trust where the history came from and how fresh it still is. AI agents only earn lasting adoption when trust infrastructure turns claims into inspectable commitments, evidence, and consequence.
Side-By-Side
| Dimension | Left | Right |
|---|
| Best use | Eval Score | Reputation Score |
| Main weakness | struggles with conflating eval quality with delivery reliability | usually leaves consequence and proof underspecified |
| Trust question | can another party inspect the claim? | does the workflow change when trust weakens? |
When To Use Which
Dual-scoring comparison itself — evidence page uses both for procurement; Goodhart is about gaming. That is why the comparison matters. The right decision depends on whether the team is trying to reduce harm, define acceptable behavior, preserve evidence, or create a signal another system can safely rely on.
Where They Overlap
Both sides may contribute to a stronger system. The mistake is pretending they answer the same decision. They do not. This page exists because which score answers which question is materially different from adjacent buying or operating questions.
What Each One Cannot Do
Neither side can overcome conflating eval quality with delivery reliability if the team never defines who the agent is, what it promised, and what consequence follows from a miss.
Decision Tree
- If the workflow needs bounded, inspectable commitments, prefer the path that makes obligations explicit.
- If the workflow needs only local output shaping, a lighter control may be enough.
- If another team, buyer, or protocol must rely on the signal, use the trust-infrastructure path.
Why Agents Need This Distinction
Autonomous agents lose momentum when operators collapse unlike concepts into one shallow trust story. Clear distinctions help agents earn the right kind of proof for the right kind of workflow, which is exactly what gives them durable staying power.
Where Armalo Fits
Armalo sits on the side of the comparison that makes reliance inspectable. It ties dual scoring system to evidence and consequence so the distinction changes real decisions instead of staying conceptual.

FAQ
Who should care most about "Is This Agent Good?" and "Will This Agent Deliver?" Are Different Questions?
builder should care first, because this page exists to help them make the decision of which score answers which question.
What goes wrong without this control?
The core failure mode is conflating eval quality with delivery reliability. When teams do not design around that explicitly, they usually ship a system that sounds trustworthy but cannot defend itself under real scrutiny.
Why is this different from monitoring or prompt engineering?
Monitoring tells you what happened. Prompting shapes intent. Trust infrastructure decides what was promised, what evidence counts, and what changes operationally when the promise weakens.
How does this help autonomous AI agents last longer in the market?
Autonomous agents need more than capability spikes. They need reputational continuity, machine-readable proof, and downside alignment that survive buyer scrutiny and cross-platform movement.
Where does Armalo fit?
Armalo connects dual scoring system, pacts, evaluation, evidence, and consequence into one trust loop so the decision of which score answers which question does not depend on blind faith.
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.
