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

With no annotations provided, the description carries the full behavioral burden. It does disclose a genuine behavioral trait beyond structured data — paid access at 0.05 USDC on Base via x402 — which is useful cost/payment context. It does not state whether the operation is read-only, what the report contains, latency, or any auth requirements.

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?

The core sentence is dense but front-loaded and informative. The 'Auto-created from research:' prefix is noise, and the bracketed pricing text is useful but appended rather than integrated, so there is modest waste.

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?

For a tool whose entire output is a trust report, there is no output schema and the description never says what the report contains or how it should be interpreted for a go/no-go decision. Combined with a generic 'input' parameter and no sibling routing, the definition is incomplete for its decision-support purpose.

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?

A single parameter with 100% schema description coverage, so the baseline is 3. The description adds no meaning to the parameter, and the schema's own description ('entrada') is effectively meaningless, but the high coverage rule keeps this at the minimum-viable baseline.

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 states a specific verb+resource: it emits a trust/identity report for agent-to-agent counterparties (wallet, DID or endpoint) prior to authorizing payments. That is clear. However, it does not differentiate itself from the many near-identical siblings such as agent-trust-scorer, agent-trust-oracle, agent-trust-verify, agent-counterparty-trust-check or agent-identity-attestor, so an agent cannot distinguish it from those.

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 usage context — 'antes de autorizar pagos o transacciones blockchain delegadas' — which implies when the tool is relevant. But it offers no explicit exclusions and never names or routes to any of the competing trust-scoring siblings, leaving the selection decision ambiguous.

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