kroger_get_coupons

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

No annotations are provided, so the description carries the full behavioral burden. It states that coupons 'can be clipped' but does not disclose whether login is required, whether the operation is read-only or modifies state, or what 'available' means. It also omits output format and potential pagination or personalization behavior.

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 containing only the essential purpose. It has no filler, redundancy, or unnecessary detail.

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 getter with no output schema and no annotations, the description covers the core action but leaves gaps around authentication requirements, return shape, and the relationship between 'clipped' coupons and the Plus card. Schema coverage helps parameter understanding, but the description alone is not fully 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 input schema describes both parameters with 100% coverage, so the baseline is 3. The description does not add any meaning beyond the schema, such as how category filtering or personalizedOnly affects results.

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 a verb and resource: 'Get available digital coupons' and adds a meaningful qualifier 'that can be clipped to the Kroger Plus card,' which distinguishes it from sibling tools like kroger_clip_coupon. The purpose is unambiguous.

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 a read/browse usage before clipping but does not explicitly state when to use this tool versus alternatives such as kroger_clip_coupon. No when/when-not conditions or exclusions are provided, leaving usage guidance implicit.

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