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

With no annotations supplied, the description carries the full burden and does meaningful work: it discloses the returned fields (nombre, barrio, dirección, horario, web, dato, link) and an explicit content boundary ('Sin precios'). It does not mention ordering, pagination behavior beyond the limite parameter, or failure modes, which keeps it short of a 5.

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 tight sentences: the first front-loads what is searched and where, the second enumerates the return payload. Nothing is redundant, though 'con nota de INPUT' is opaque jargon that a reader outside the publication's vocabulary may not resolve.

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?

There is no output schema, so the description's return-field list is genuinely necessary and it supplies it. Combined with full schema coverage on the inputs, an agent has enough to call this correctly; only result ordering and the meaning of 'dato del lugar' remain underspecified.

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 100%, so all three parameters (barrio, limite, consulta) are already documented with examples and defaults in the schema. The description adds no syntax or interpretation guidance for them beyond the general domain, so the baseline 3 applies.

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 ('Busca') and a concrete resource set ('bares, cafés, librerías y espacios culturales de Buenos Aires'), and ties it to a named source section ('Dónde ir'). That content scoping implicitly separates it from buscar_discos, buscar_juegos and buscar_notas, but no sibling is named explicitly, so differentiation still requires the agent to infer it.

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?

Usage is only implied by the domain ('Dónde ir' places). There is no statement about when to prefer this over buscar_notas or notas_recientes, and no mention of prerequisites or what happens with zero results. 'Sin precios' is a scope exclusion, not routing guidance.

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