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

With no annotations, the description carries the full burden; it does add genuinely useful behavioral detail that prices are in øre (DKK) and that results are paginated via cursor/limit. However, it says nothing about whether query is optional, what a default or maximum limit is, whether results are ranked, or what the response contains.

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?

Two compact sentences, front-loaded with the verb and resource, followed by a dense structural sketch and a units note. Nothing is padded; the brace notation efficiently conveys the nested payload shape.

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 nested-object tool with no annotations and no output schema, the description covers the input shape and currency units but leaves return semantics, result ranking, and pagination limits unexplained. It is adequate to attempt a call but not to predict its behavior.

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 50% and the catalog parameter is declared as a bare object with no properties, so the description does real work by enumerating query, filters.categories, filters.price.min/max, and pagination.cursor/limit. It stops short of explaining types, defaults, or whether nested fields are optional.

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 states a specific verb and resource ("Søg i Flowerings katalog") and ties it to the underlying operation (UCP catalog.search). It is clear enough to distinguish from a single-product fetch, though it does not explicitly name lookup_catalog or get_product as the narrower alternatives.

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?

There is no when-to-use or when-not-to-use guidance, and no mention of the sibling tools lookup_catalog or get_product that an agent could easily confuse with a catalog search. The only hint is the presence of query/filter fields, which implies usage but never states conditions.

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