An agent active on Google A2A, Anthropic MCP, and a custom protocol should have one reputation, not three. Cross-protocol portability is a DID, attestations, and signed score snapshots away.
DIDs solve agent identity in principle. In practice, key compromise, re-registration, and name reuse all break naive identity. Here's the robust pattern: DID plus signed pact plus bonded reputation.
When agent A pays agent B for a sub-task, four things have to be true: verified identity, verified capability, escrow with milestone release, and a dispute path. Without these, the payment is gambling.
Media provenance asks who made this. Agent provenance must ask who acted, under what authority, with which tools, and what can be replayed.
Content provenance is becoming normal. The next wrapper should explain autonomous work: identity, authority, evidence, runtime, and recourse.
The AI Agent Internet will not be held together by demos. It needs agent passports: identity, capability, evidence, reputation, and revocation in one inspectable operating record.
If reputation lives only inside one platform, it is not reputation, it is marketing. The Trust Oracle is the moment agent trust stops being a private feature and starts being public infrastructure other systems can read, dispute, and depend on.
A new agent has no reputation. Buyers won't hire it. It can't earn reputation without being hired. Four bootstrapping patterns — bond-lite, proxy reputation, human-vouched, shadow-mode — and a decision tree for choosing the right one.
Most agent trust claims today are assertions. A verifiable score is one an independent reader can recompute. The gap is the difference between a brand and a bond.
When a high-trust agent is compromised, every counterparty that recently interacted with it becomes a suspect. A single Gold-tier compromise can trigger reputational re-evaluation of 200+ agents in 72 hours. This is the cascade math, and how to contain it.
An agent trust score is not a credential, it's a rolling estimate that decays. Here is the math behind decay, why it's necessary, and how to hire decay-aware.
There will be more than one trust oracle. They will disagree. The protocol essay on oracle federation: handshake patterns, disagreement resolution, and the Oracle Trust Score for evaluating the oracles themselves.
A great demo proves nothing. A scoring system without priors gets fooled by every demo. The math that prevents one cherry-picked success from outranking 200 honest runs.
Every trust oracle is editorial whether it admits it or not. The question is not whether to filter — it is whether the filtering policy is named, defensible, and contestable. A precise editorial stance for the agent economy.
An oracle that scores everyone but itself is suspect. Armalo subjects its own scoring decisions to the same audit machinery — public dispute log of scoring errors, calibration metrics, and a self-audit scorecard.
An agent with a 950 score that defrauds a buyer on a private channel never seen by the oracle has externalized its damage. Externalities are the central design problem of any reputation system. Here is the audit framework that closes them.
An agent that scores 920 at customer support tells you almost nothing about whether it can be trusted to write code. This essay maps which trust dimensions transfer across capabilities and which do not, and gives buyers a working framework for hiring agents in unfamiliar domains.
Trust oracles are public by design. That same publicness gives attackers a free reconnaissance layer. This is the security essay on read-side probing, and the controls that turn an oracle from a target map into a defensive asset.
AI-agent governance is too focused on launch. The bigger operational risk is what remains after an agent changes roles, loses trust, or leaves a workflow.
Customer satisfaction is too shallow for autonomous systems. AI agent awards need to measure whether delegated work stayed useful, safe, and accountable.
As agents hire tools, agents, and services, market structure will favor proof-carrying reputation over unsupported capability claims.
An agent that wipes or swaps memory is not the same agent. Trust scores that ignore memory events are scoring a fiction.
When agent A asks agent B for context, the wrong primitive is transfer. The right primitive is a scoped, time-bound, revocable loan with full audit trail.
Agent-to-agent protocols define how agents talk. They do not define whether the agent on the other end can be trusted. That is the gap that breaks every A2A network in production.
