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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuinely useful return-shape semantics, notably that edited games carry a solo_en flag indicating store-exclusive publishing, but says nothing about failure behavior when the name/slug is not found.

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?

A single efficient sentence that front-loads what the entity is and what accompanies it. The parenthetical about solo_en is dense but earns its place by clarifying the return payload.

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 one-parameter lookup with no output schema, the description covers the entity type, the country field, and the developed-vs-edited game distinction including the solo_en flag. Missing only error/not-found behavior, which is a minor gap.

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?

Only one parameter exists and schema coverage is 100%, with the schema itself documenting the name-or-slug format and giving examples. The description merely restates the same name/slug duality, adding no new syntax or format detail; baseline 3 for full schema coverage is appropriate.

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?

States a specific resource (un estudio o editora) and what is returned (su país y sus juegos), which lets an agent distinguish it from game-focused siblings like ficha_juego or buscar_juegos. It lacks an explicit retrieval verb and never names an alternative tool, so it falls short of full sibling differentiation.

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 when-to-use guidance, no when-not-to-use, and no mention of any sibling tool. 'Acepta el slug o el nombre' is an input-format note, not a usage condition, so an agent gets no routing help from the description.

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