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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the temporal scope (years from 1998) but says nothing about auth requirements, pagination, or result size; with annotations carrying the safety burden, a 3 is appropriate.

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 short fragments with no filler, and the catalog contents are front-loaded before the routing hint. The first fragment is a bare noun phrase, which is terse to the point of being slightly cryptic, but nothing is wasted.

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?

An output schema exists, so return-value structure need not be explained, and the read-only annotations cover the safety profile. For a zero-required-parameter discovery tool, the description supplies enough to call it and route onward; only the absence of any scope/limit note keeps it from a 5.

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 optional `format` parameter with 100% schema description coverage, so the schema already documents the text/json choice fully. The description adds no format syntax or default behavior beyond what the schema states, making the baseline 3 correct.

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 enumerates the exact catalog dimensions returned — report types, years (with the 1998 lower bound), and company groups — which tells the agent this is a discovery/enumeration tool rather than one returning report data. It lacks an explicit verb ("Lists..."), relying on the name to supply it, so it is clear but slightly implicit.

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?

"Next: get_arconel_reporte" is a concrete routing instruction that tells the agent this tool is the discovery step preceding get_arconel_reporte, which is the key usage signal. It does not state when NOT to use it or name other alternatives, but the workflow direction is unambiguous.

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