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 hints at a read-only lookup ('consultar') but discloses nothing about return format, whether the value counts pending vs confirmed separately, or any constraints — for a no-annotation tool this is a significant gap.

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?

Short and front-loaded with the concept, followed by a compact two-argument block. The concept sentence answers 'what is a nonce' rather than 'what does this tool do', but nothing is padded.

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?

With no output schema and no annotations, the description leaves the return value ambiguous — it does not say whether a number, a list, or both confirmed and pending counts are returned. For a simple 2-param query tool this is adequate but not complete.

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?

Schema coverage is 0%, so the description must compensate and it largely does: it gives the allowed `red` values (`base` or `ethereum`), which the schema lacks as an enum, and explains `direccion` as the wallet whose counter is queried. This is real added value over the bare schema.

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 defines what a nonce is (sent transactions, confirmed and pending) but never states the tool's action as a verb — it never says it returns the counter for an address. The arg note ('Cartera cuyo contador se quiere consultar') implies the query, but the purpose is inferred rather than declared, and it does not distinguish itself from siblings like transaccion or saldo.

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?

There is no explicit when-to-use or when-not-to-use guidance and no named alternative among siblings such as transaccion or estado. Usage is only weakly implied by the argument notes.

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