CatalogItems_getCatalogItem

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

There are no annotations, so the description must carry the full behavioral burden. 'Retrieves' implies a read-only operation, but the description does not disclose required authentication, input requirements, side effects, or what 'Runs in your Kuudo deployment, not here' actually means for execution. The ambiguous 'Catalog entry.' sentence adds confusion rather than transparency.

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 short and mostly front-loaded, but the first sentence 'Catalog entry.' is a redundant fragment that adds no value. The environment sentence may be useful but is vaguely worded. The definition would be stronger if it removed the fragment and clarified the deployment distinction.

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?

For a get-by-identifier operation, the description does not explain how the item is specified, what identifiers are accepted, or what details are returned. This is especially important because the input schema is empty and there is no output schema or annotations to fill the gaps. The deployment note is useful but 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?

The input schema declares zero properties, so there are no parameter semantics for the description to supplement. With 0 parameters, the baseline is 4. The description does not clarify how the target catalog item is identified, but the schema itself provides no parameter definitions either, so this is not a failure of the description to complement the schema.

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 action and resource: 'Retrieves details for an item in the Amazon catalog.' This is more specific than the tool name alone and helps distinguish it from search-like siblings. However, the opening phrase 'Catalog entry.' is vague and the environment note detracts slightly from an otherwise clear purpose.

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?

No explicit guidance is provided about when to use this tool versus alternatives such as CatalogItems_searchCatalogItems or CatalogItems20201201_getCatalogItem. The phrase 'Runs in your Kuudo deployment, not here' hints at an environment constraint but does not explain the conditions under which this tool should be selected.

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