get_product_catalog_item

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

No annotations are provided, so the description carries the full burden. It only says 'Get details' and adds no context about return format, error behavior, permissions, or rate limits. Unlike a tool with annotations that at least establish read-only safety, this minimalist description provides no behavioral disclosures beyond the action itself.

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 clear sentence of eight words, front-loaded with the action and resource. No unnecessary words or repetition.

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?

There is no output schema, so the description should clarify what 'details' are returned, but it does not. Also, the three required parameters (publisher_id, catalog_id, identifier) are not explained in terms of their relationship or why all are needed. This is insufficient for a tool in a complex domain with many related entities.

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% with each parameter having a basic description ('Catalog ID', 'Unique identifier for the catalog item', 'Publisher ID'). The tool description adds no additional meaning beyond what the schema already provides, so the baseline of 3 applies.

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 'Get details of a specific product catalog item' uses a specific verb ('Get') and resource ('product catalog item') with a clear scope ('specific'), distinguishing it from sibling tools like 'list_product_catalogs' and 'search_product_catalog_items'.

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 explicit guidance on when to use this tool versus alternatives such as 'get_product_catalog' or 'search_product_catalog_items'. The usage is implied (when you have the identifier for a single item), but no exclusions or alternative conditions are provided.

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