Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full behavioral burden. It does disclose the payment model (x402, 0.05 USDC on Base, pay-per-use), which is real behavioral context an agent needs before calling. However, it says nothing about what the returned score means, its range or interpretation, latency, or failure behavior — large gaps for a scoring service.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, with the core purpose front-loaded and the pricing bracket clearly separated at the end. The 'Auto-created from research:' prefix is low-value noise, but the rest is compact and earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, no annotations, and an opaque required parameter. For a tool whose entire value is the score and risk profile it returns, the description explains neither the shape nor the interpretation of the result, so an agent cannot know what to do with the output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There is a single parameter named 'input' whose schema description is the content-free word 'entrada'. Although nominal schema coverage is 100%, that coverage conveys no meaning, and the tool description likewise never says what the input string should contain (a counterparty address, an agent ID, a payload?). The agent is left guessing at the one thing it must supply.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb+resource in Spanish: it generates a trust score and risk profile for autonomous-agent counterparties. That is a concrete, actionable purpose. It does not, however, differentiate itself from the many near-identical siblings (agent-trust-score, agent-trust-oracle, agent-trust-verify, agent-counterparty-trust-check), so an agent cannot tell which trust tool to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a genuine usage moment — run this before authorizing economic transactions or delegating authority — which is more than most definitions offer. But with a dozen overlapping trust siblings, there is no guidance on when to choose this tool over them and no exclusions, leaving the routing decision to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
