kroger_view_cart

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

No annotations are provided, so the description carries the burden. The word 'view' correctly implies a read-only operation with no side effects. However, it does not disclose whether authentication is required, whether the cart must be initialized, or what exact data the response contains (beyond items, prices, totals). It is minimally transparent but not deeply informative.

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, well-structured sentence that immediately conveys the tool's purpose. Every word earns its place, with no filler or redundant 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 simple, no-parameter view tool, the description adequately covers the core function. It mentions the key outputs (items, prices, totals). It doesn't specify the exact response format or potential prerequisites (like login), but given the low complexity and no output schema, the description is reasonably 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?

The tool has zero parameters, which makes parameter documentation unnecessary. Per the baseline for 0-param tools, a score of 4 is appropriate. The description adds nothing about parameters because there are none to describe.

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 uses a specific verb ('View') and clearly identifies the resource ('current items in the Kroger shopping cart') and the key details shown (prices and totals). It is immediately distinct from sibling tools like kroger_add_to_cart or kroger_checkout, which have different actions.

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 implies the tool is for reading the cart contents (inspect before checkout), and the verb 'view' clearly signals a non-modifying operation. It does not explicitly name alternatives or exclusions, but the context of sibling tools makes the usage obvious.

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