get_game_info

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

No annotations are provided, so the description carries the burden. It discloses the return fields (ID, name, box art URL), which is useful, but it doesn't mention any potential errors, rate limits, or confirm that it's a read-only operation beyond the verb 'Obtiene'. The description adds value but lacks deeper behavioral context.

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?

The description is two concise sentences that immediately state what the tool does and what it returns. There is zero filler or redundancy, and the key information is front-loaded.

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 simple single-parameter lookup with no output schema, the description provides sufficient information: it names the resource, the lookup method, and the return fields. It could be slightly more complete by explicitly contrasting with get_top_games, but overall it's adequate for its simplicity.

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?

The schema has 100% coverage for the single parameter game_name, with a clear Spanish description. The tool description adds no additional parameter semantics beyond restating that the game is searched by name. The schema does the heavy lifting, so baseline 3 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?

The description clearly states a specific verb ('Obtiene'), resource ('información de un juego en Twitch'), and the method ('por su nombre'). It also lists the return fields, distinguishing it from siblings like get_top_games which list games rather than retrieve detail by name.

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?

The description implies the tool is for when you have a specific game name, which distinguishes it from get_top_games or other list-oriented tools. However, it doesn't explicitly state exclusions or name alternative tools, so it's clear but not fully explicit.

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