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

No annotations are provided, so the description must carry the behavioral burden. It does convey useful context (currency basis 'from SEK', 2026 pricing year, read-only price retrieval), but it says nothing about what is returned (e.g. a model list with prices) or whether results are paginated or exhaustive.

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 tight sentences with the core purpose front-loaded and the optional filtering stated second. Every word earns its place; no filler.

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 two-parameter, zero-required read-only lookup with no output schema, the definition covers what the tool retrieves and how it can be narrowed. The only real gap is that it never hints at the shape of the returned price data, which is minor for this complexity level.

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 description coverage is 100%, so the schema already documents both parameters and their enum/units. The description restates the filters and adds only the currency context ('from SEK'), matching the baseline 3 for schema-covered parameters.

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 a specific verb and resource ('Get Husverket's 2026 turnkey prices') plus the two product categories it covers, so an agent can distinguish it from list_categories or get_company_info. It does not explicitly distinguish itself from search_husverket, which is the closest sibling.

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 sentence 'Optionally filter by category or max price' implies the tool is a lookup that can be narrowed, but there is no explicit when-to-use guidance and no mention of when search_husverket would be the better choice. Usage is only implied.

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