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, and it discloses almost nothing: no auth requirements, no units or currency, no indication of whether the returned figures are aggregated, rates, or totals. The only concrete behavior conveyed is the date-range scoping.

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?

Very compact and front-loaded: metrics first, then the range constraint and format. The slash-separated bilingual fragment is slightly cryptic but there is no wasted prose.

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 annotations, no output schema and 0% parameter coverage, this tool needs more than a terse fragment. An agent cannot tell what the response contains, in what units, or what constraints the date range carries, leaving meaningful gaps for a data-retrieval tool.

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 description coverage is 0% and both fecha_ini/fecha_fin are undocumented in the schema, so the description must compensate. It does usefully supply the expected date format (yyyy-MM-dd) and implies the pair forms an inclusive range, but adds nothing about which ranges are valid or what the boundaries mean.

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 concrete resource and scope — public finance data covering Gasto, ISR, IVA and IEPS over a date range — which is clearly distinct from siblings like get_tasa_hoy, get_dolar_hoy or get_udis_hoy. It lacks an explicit verb, but the metrics and domain make the purpose unmistakable.

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 specifies a date range but gives no guidance on when to prefer this tool over alternatives or what prerequisites apply. There is no mention of when-not to use it, nor any reference to sibling tools covering other financial indicators.

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