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

Adds context beyond readOnlyHint/openWorldHint: no authentication required, prices depend on the configured store, and sections are inconsistently present ("Not every product has every section"). The untrusted-content warning about Bilka-supplied names and offer texts is a valuable instruction-injection guard. Only the failure behavior for an unknown or malformed id is left unstated.

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?

Three sentences, front-loaded with the returned payload, then the id source, then the safety note. Every sentence carries distinct information; nothing is repeated from the title or schema.

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?

There is no output schema, and the description compensates by enumerating the returned fields and flagging that ingredient/allergen and nutrition sections are conditional. For a single-parameter read tool this covers everything an agent needs to call it and interpret the result.

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 coverage is 100%: the single product_id parameter already carries its pattern and an example ("19753"). The description only reinforces the provenance ("from search_products"), which is useful but adds no syntax beyond the schema, so baseline 3 applies.

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?

States precisely what is retrieved for a single product (size, DKK prices at the configured store, unit price, category, labels, page sections) and names the sibling that supplies the id. An agent can tell it apart from search_products or list_categories without inspecting any schema.

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?

"Take product ids from search_products" gives an explicit upstream dependency and the correct alternative for discovery, and "Needs no login" removes a common prerequisite doubt. It does not state a when-not-to-use case (e.g. bulk retrieval), so it stops short of a 5.

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