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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only the notion of 'filter facets', with no detail on pagination, locale/region behavior, or result volume that would go beyond the structured hints.

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 efficient sentence with the core resource front-loaded and no filler. It is appropriately sized for the amount of information conveyed, though it is arguably too terse given the surrounding ambiguity.

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?

The output schema exists, so return values need not be described, but the tool's cryptic parameters, lack of sibling differentiation, and absence of any usage context leave the definition under-specified for a 3-parameter browse endpoint.

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 description coverage is 0% and the three parameters (l, cc, page) are cryptic single-word names that the description never explains. 'Filter facets' hints that filtering exists but does not map to any parameter, so the description fails to compensate for the coverage 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 states a clear verb+resource: browsing the PlayStation Store 'all-games grid'. That is more specific than a generic catalog browse, but it offers no differentiation from nearby siblings such as playstation_category, playstation_latest, playstation_deals, or playstation_search, which also surface game listings.

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 guidance, no mention of when this is preferable to playstation_search or playstation_category, and no stated prerequisites. The agent is left to infer that this is the general unfiltered grid view.

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