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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered by structured data. The only behavioral addition is the 'latest first' sort order, which is useful but thin; no pagination, result-size, or empty-result behavior is disclosed.

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?

It is short and front-loaded, but the Korean and English sentences are verbatim duplicates, so roughly half the text is redundant translation rather than added 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 read-only, two-parameter list tool with no output schema, the description is minimally sufficient. It nonetheless omits the default and maximum page size (10/20) and what the returned guides contain, which an agent would want when deciding how to page.

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 game parameter carries a description (a slug, cross-referencing list_games) but limit is described only by default/min/max constraints. The description adds nothing about either parameter, not even that filtering by a game slug narrows results, so it does not compensate for the gap.

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 gives a clear verb+resource ('latest strategy guides from the GameBattle community') plus an ordering hint (최신순/latest). It is not a tautology, but it never contrasts itself with the closest siblings such as list_games or search_battle_zones, so an agent must infer the distinction.

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 or when-not-to-use guidance. The description never mentions the related list_games or any search_* sibling, nor does it say whether the game filter is required to get meaningful results.

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