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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and reach are covered. The description adds only the domain pin, and says nothing about ordering, whether the list is pinned/featured, or any pagination behavior beyond what the schema states. With annotations doing the heavy lifting, this is a thin addition.

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 short sentence with no filler, front-loaded with the resource. It is efficient, though the parenthetical URL feels slightly like internal bookkeeping rather than agent-facing guidance.

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 no explanation, and the two parameters are documented. However, for a listing tool with a natural sibling (psastore_collection_products), the absence of any navigation or scope guidance leaves a meaningful gap.

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 100% for both page and limit, including default and max values, so the schema fully documents the parameters. The description adds no parameter meaning, which matches the baseline of 3 when structured data carries the load.

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?

Names the specific resource (storefront collections) and scopes it to the PSA Team Store site pinned at https://store.psacard.com, which distinguishes it from the news/media tools in the broader toolset. It lacks an explicit verb (list/retrieve) and does not explicitly contrast with the nearby psastore_collection_products sibling, so it is clear but not fully differentiated.

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 gives no when-to-use guidance, no prerequisites, and never mentions the obvious alternative psastore_collection_products for fetching the products inside a collection. The agent must infer the relationship from the tool name alone.

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