kroger_get_delivery_slots

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

With no annotations provided, the description carries the full burden. It indicates a read-only operation via 'Get', but does not disclose any prerequisites (e.g., items in cart, active session) or side effects. It adds minimal behavioral context beyond the obvious action.

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 front-loaded sentence with no fluff. Every word contributes: 'Get', 'delivery time slots', 'current cart and store' are all essential. It is appropriately sized for a simple getter tool.

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?

No output schema exists, so the description should clarify return expectations. It does not explain what happens when no date is provided, the range of slots returned, or the response structure. For a simple tool it is minimally adequate but lacks these details.

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 description coverage is 100%, so the schema fully documents the optional 'date' parameter. The description does not add extra meaning about the parameter, just restates the cart/store context. Baseline of 3 is appropriate.

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 the verb 'Get' and the resource 'available delivery time slots' for the current cart and store. It explicitly specifies 'delivery', distinguishing it from the sibling tool 'kroger_get_pickup_slots'.

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 usage context (for the current cart and store) but does not explicitly state when to use delivery slots vs pickup slots or mention alternatives. It gives no exclusions or conditions, so guidance is implied rather than explicit.

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