CatalogItems20201201_searchCatalogItems

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

With no annotations, the description carries the full disclosure burden, but it only reveals an execution-environment trait ('Runs in your Kuudo deployment, not here') whose meaning is undefined. It does not state whether the operation is read-only, whether authentication is required, whether results are paginated, or any rate-limit or side-effect considerations.

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 at three sentences, but the opening 'Catalog entry' is a tautological label that restates the tool's domain without adding information. The deployment note is placed awkwardly before the functional clause, and the structure does not clearly lead with the most decision-relevant information.

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 search tool with no output schema, no annotations, and an empty input schema, the description leaves too much unspecified: the meaning of 'associated information', how to construct a valid search request, pagination behavior, and what distinguishes this 20201201 version from its siblings. The agent cannot reliably select or invoke this tool based on the provided context alone.

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 schema documents zero parameters, so the described baseline for 0 params is 4. The description adds only the notion that this is a search operation returning a list of items, implying query/filter inputs exist, but it names none of them, leaving the agent without guidance on what to pass given the schema's empty properties and additionalProperties: true.

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 main clause states a specific verb and resource: 'Search for and return a list of Amazon catalog items and associated information.' This is clear and actionable. However, it does not differentiate from the sibling CatalogItems_searchCatalogItems or the newer 20201201 get variant, so the version-specific purpose remains ambiguous.

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 guidance is given on when to use this tool versus alternatives such as CatalogItems_searchCatalogItems or CatalogItems20201201_getCatalogItem. The cryptic note 'Runs in your Kuudo deployment, not here' hints at an environment constraint but does not explain the selection criteria for this tool, leaving the agent to guess among several near-identical catalog siblings.

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