microsoftstore_category

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

With no annotations, the description carries the full behavioral burden. It discloses pagination (cursor-paginated), defaults (media_type defaults to apps), constraints (all not accepted), and that it is credential-free public data read directly from the store's API. It does not describe error handling or response shape, but for a read-only listing tool these are minor gaps.

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?

The description is a single dense paragraph that front-loads the purpose ('Browse a Microsoft Store category without a keyword') and then efficiently covers pagination, the contrast with search, parameter constraints, and credential-free access. Each sentence adds value, though the long first sentence is a bit run-on. Overall it is appropriately sized.

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 description explains pagination and parameter defaults but does not describe the response structure or error cases. Since there is no output schema, an agent might need to know what a 'page' contains (e.g., product IDs, titles, prices) to use the result effectively. It also references another doc for category lists, creating a dependency. For a simple read-only listing tool, it is adequate but not fully complete.

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% (all params have descriptions), so baseline is 3. The description adds meaningful semantic context beyond the schema: category is required, accepted categories depend on media_type, media_type defaults to apps, and 'all' is not accepted. This helps an agent understand dependencies and valid inputs beyond the raw schema fields.

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 clearly states a specific verb-resource pair: browse a Microsoft Store category without a keyword. It distinguishes itself from the sibling search tool by noting that search requires a non-empty query and returns nothing for an empty one, making the purpose unambiguous. It also specifies it returns a cursor-paginated page of a department+category listing.

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 explicitly contrasts with /microsoftstore/search by explaining that search requires a non-empty query and returns nothing for an empty one, implying this tool is for browsing an entire category without a keyword. It also notes media_type 'all' is not accepted and references the search doc for accepted category lists, giving clear context on when to use this tool. However, it does not exhaustively enumerate all alternatives or edge cases.

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