kroger_reorder

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

With no annotations, the description carries the full burden of behavioral disclosure, but it merely states an action without revealing consequences. It is unclear whether reorder adds items to the current cart, replaces the cart, or immediately creates a new order, and no mention is made of the effect on the existing cart or confirmation steps.

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 concise sentence with no wasted words, effectively communicating the core action. While it is terse, it is appropriately sized for a simple tool and does not contain unnecessary filler.

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 mutation tool with no annotations and no output schema, the description is incomplete. It fails to explain the outcome (add to cart vs. direct order), prerequisites such as login, or its relationship to sibling tools like checkout or cart management, leaving significant gaps for an agent to navigate.

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 already fully describes the only parameter (orderId) as 'Previous order ID to reorder' with 100% coverage. The description adds no further meaning, such as where to find the order ID or any expected format.

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 names the action (Reorder) and the target resource (items from a previous order), making its purpose immediately understandable. It distinguishes itself from sibling tools like kroger_get_order_history (viewing orders) and kroger_checkout (processing current cart).

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 usage guidance is provided. The description does not mention prerequisites (e.g., being logged in), where to obtain the orderId (e.g., from kroger_get_order_history), or when to use this tool versus alternatives like adding items manually or going directly to checkout.

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