kroger_get_product_details

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

There are no annotations, so the description must carry full weight. It states what data is returned, but does not disclose whether authentication is required, whether the call is read-only, or what happens for invalid/unknown product IDs. This leaves the agent without a clear safety or error-handling profile.

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 filler. It concisely answers what the tool does and what info it returns, earning every word.

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 single-parameter getter with no annotations and no output schema, the description covers the core purpose and return content. However, it lacks guidance on prerequisites (e.g., login) and any behavioral caveats (e.g., availability of nutrition data varies by product), leaving some gaps for full contextual completeness.

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 schema has 100% coverage for the single parameter, describing 'productId' as 'Kroger product ID'. The description adds no additional parameter context beyond implying it refers to a specific product, so it neither improves nor degrades the semantic clarity offered by the schema.

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 ('Get') and identifies a clear resource ('detailed information about a specific product'). It lists concrete fields (nutrition facts, ingredients, availability) and implicitly distinguishes itself from sibling tools like search_products, which returns a list rather than details for a single product.

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 this tool is used when a specific product is already known, contrasting with search_products. However, it does not explicitly state that the productId comes from a preceding search, nor when not to use it. There is no explicit mention of alternatives or prerequisites.

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