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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety and idempotency profile is fully covered. The description adds useful detail that results include id/title/url and that ids feed 'fetch', but it does not disclose ranking, pagination, or result-count behavior for a search tool.

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 what is returned, the second explains the id-to-fetch handoff. Nothing is wasted, though the sentence runs a bit long with the parenthetical enumeration.

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 single-parameter read-only search with annotations covering the safety profile and no output schema, the description covers purpose, result shape (id/title/url), and the follow-up fetch step. It is nearly complete; only pagination/ranking and explicit sibling differentiation are missing.

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%, with the sole 'query' parameter documented as accepting Spanish or English text plus min/max length. The description adds no syntax or format guidance beyond the schema, so the baseline of 3 is appropriate for a fully documented single parameter.

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 ('Searches') and resource ('datosmcp for Central American public data'), and enumerates the three result categories (indicators, places, direct answer). It is clear but does not distinguish itself from the many search_* siblings in the toolset, which leaves some risk of wrong-tool selection.

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 says it returns ids that should be passed to 'fetch' for full text, which implies a two-step search-then-fetch workflow. However, there is no explicit when-to-use guidance versus the numerous sibling search tools (search_data, search_places, search_news, find_indicators, list_places, etc.), leaving usage context implied rather than stated.

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