kroger_cart_auth_status

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that the tool checks token existence but does not explicitly note read-only behavior, potential error conditions, or prerequisites like an active session, leaving the agent to infer safety and side effects.

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 redundant or verbose language. Every word contributes to understanding, making it appropriately concise for a simple status-check 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?

Given the tool's low complexity (zero parameters, output schema present), the description covers the core functionality adequately. However, it lacks contextual placement within the broader cart authentication workflow, such as when to call this status check relative to sibling tools like start_kroger_cart_auth or complete_kroger_cart_auth, leaving an incomplete picture for an agent navigating the process.

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 has zero parameters, so the baseline is 4. The description adds meaningful context by introducing the concept of a 'local user cart token,' which is absent from the empty schema, though no parameter-specific details are needed.

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 ('Check') and resource ('local user cart token'), clearly distinguishing this status-check tool from sibling auth flow tools like start_kroger_cart_auth and complete_kroger_cart_auth. It directly answers what the tool does.

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 provided on when to use this tool versus alternatives. It does not mention placement in the auth workflow (e.g., before starting or after completing auth) or any conditions that would trigger its use.

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