metacritic_game_critic_reviews

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

With no annotations, the description discloses that the tool returns paginated data, lists the fields returned, and states it is credential-free public data. It does not mention rate limits or potential destructive effects, but the read-only nature is implied. The transparency is good but could be improved with rate limits or data freshness.

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 extremely concise with two sentences: the first states the purpose and return fields, the second notes the credential-free nature. It is front-loaded, no wasted words, and efficiently conveys essential information.

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 listing tool with 4 parameters all documented in the schema, the description covers the purpose, return fields, and auth requirements. It does not explain the return format (e.g., array) but that is typical. The completeness is adequate for the tool's complexity.

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 coverage is 100% with all parameters described (page, slug, sort, per_page). The description adds overall context (critic reviews, paginated, returned fields) but does not elaborate on individual parameters beyond what the schema already provides. The baseline is 3 for high schema coverage, and the description adds marginal value.

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 the tool lists Metacritic game critic reviews, specifying it returns paginated professional/publication reviews with fields like publication, score, quote, author, platform, and source URL. It distinguishes from the sibling tool 'metacritic_game_user_reviews' implicitly by focusing on critic reviews.

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 specifies the tool is for critic reviews and that it is credential-free, implying it can be used without authentication. However, it does not explicitly contrast with alternatives like metacritic_game_user_reviews or metacritic_game, but the sibling tool names provide context. No explicit when-not-to-use guidance is given.

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