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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and open-world profile is covered. The description adds 'paginated', a genuinely useful behavioral trait not present in the annotations, but says nothing about rate limits, result caps, or how paging relates to page/page_size. Adds modest value over the annotations.

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 front-loaded sentence with no filler; every clause (search target, scope, pagination) carries information. It is efficiently structured, though the extreme brevity leaves the parameter gaps it should ideally cover.

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?

An output schema exists, so return values need not be described. But with five parameters at 0% coverage and regional/locale fields that materially change results, the description is too thin to let an agent invoke this correctly. The pagination hint alone is insufficient.

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% across 5 parameters, so the description must carry the semantics and mostly does not. 'Paginated' vaguely gestures at page/page_size, but the required term and especially 'l' (language) and 'cc' (country code) are left entirely undecoded, so an agent cannot know what values are valid or what region/locale defaults apply.

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?

States a specific verb (Search) and resource (PlayStation Store) and clarifies scope as concepts and products, which distinguishes it from detail tools like playstation_concept and playstation_product. However, it does not distinguish itself from close siblings such as playstation_browse, playstation_category, or playstation_suggest, so it stops short of a 5.

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 or mention of alternatives. With siblings like playstation_browse, playstation_latest, and playstation_suggest, an agent gets no help deciding when search is the right entry point versus those. Usage is only implied by the word 'Search'.

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