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

With no annotations provided, the description carries the full burden. It discloses that this is credential-free public data, explains pagination behavior via next_page, and specifies that cc selects currency and l uses the locale's primary language for text. It does not mention rate limits or error behavior, but for a read-only browse operation the disclosed traits are substantial.

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?

Three sentences with no filler: the first states the core purpose and return contents, the second covers pagination, and the third explains the two optional parameters plus the credential-free nature. Information is front-loaded and every sentence 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?

For a browse tool with no output schema and no annotations, the description covers the essential context: what is returned (items with price/platforms/media, filter facets), how pagination works, how region and language are selected, and that no credentials are needed. It lacks explicit return structure details and error handling, but is complete enough for an agent to invoke it correctly.

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%, so the baseline is 3, but the description adds meaningful semantics beyond the schema: it explains that cc selects both region and currency, that l accepts a locale like en-US with primary language extraction, and that page advances with next_page signaling more results. This extra context helps an agent use the parameters correctly.

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 opens with a specific verb and resource: 'Browse a PlayStation Store category grid' and clarifies it returns a page for a specific category UUID with item prices, platforms, media, and filter facets. This clearly distinguishes it from sibling tools like playstation_search, playstation_deals, or playstation_product without needing to open their schemas.

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 explains how to paginate ('Pass page to advance; next_page is set when more results exist') and how cc/l affect region and language, which is useful usage context. However, it does not explicitly state when to choose this tool over alternatives or mention any exclusions, leaving the selection criteria implied rather than stated.

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