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

With no annotations, the description carries the full disclosure burden. It does useful work by explaining what each ranking is based on (anticipation votes vs. star ratings) and what fields accompany entries (release date, platform, trailer link), effectively pre-describing return content. However, it says nothing about ordering rules, pagination, or any access constraints.

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 dense sentence that front-loads the core resource and packs the ranking basis and included fields without filler. Slightly compressed but every clause earns its place.

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?

No output schema and no annotations, so the description justifiably covers returned fields. But it omits usage context and leaves the 'limit' parameter unexplained, leaving gaps for a simple read tool with a 50%-covered schema.

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 50%: the 'list' enum has its own description and the description's two ranking modes roughly map to it. But 'limit' is undocumented in both schema and description, so its behavior (count, page size?) is unaddressed. Baseline 3 is appropriate given partial coverage.

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 resource (game hype rankings) with two well-defined modes: unreleased games ranked by member anticipation votes, and released games ranked by 1-5 star ratings. An agent can tell this is a ranking tool, distinct from release_calendar or official_game_trailers, though it never explicitly names or contrasts with those siblings.

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 explicit when-to-use guidance or routing to alternatives. The description implies the tool is for rankings, but an agent choosing between this, release_calendar, and official_game_trailers gets no conditions from the text.

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