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

No annotations are provided, so the description carries the full burden. It discloses the composite nature, the guarantee about identical `query` across sections, and warns users never to construct `https://tradedashboard.eu/...` URLs but to use the provided `links`. It also states the response shape. It does not discuss auth, rate limits, or error conditions, but for a read-only aggregation tool with this level of detail, it is quite transparent.

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 longer than a one-liner but every sentence carries meaningful information: the composite purpose, the consistency guarantee, the defaults rationale, override guidance, and return format. It is well-structured with a clear flow from purpose to usage to output. Although it could be tightened slightly, it remains efficient for the complexity it covers.

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?

Given the tool's complexity (nested `query` object, 2 top-level params, many subfields) and the presence of an output schema, the description is complete. It tells the agent when to invoke this composite tool, what the response structure looks like, and critical caveats (link construction, shared query). The output schema presumably details individual section contents, so the description doesn't need to repeat that. It fully supports correct selection and invocation.

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 baseline is 3. The description adds value by explaining that `query` is the same request body used across all endpoints, that its defaults are sensible for a first-cut report, and that only `product` is required. It also clarifies that all five sections share the identical `query` slice, which is not obvious from the schema alone. This exceeds baseline without duplicating field-level details already in 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 opens with a specific verb+resource: "Fetch every report section ... for one shared `query` in a single call" and immediately distinguishes itself from sibling tools by naming them (`get_product_profile` / `get_market_summary` / ...) and explaining the alternative. This clearly tells an agent what the tool does and how it differs from closely related endpoints.

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?

It explicitly states when to use this tool: "instead of calling ... separately yourself" and provides a strong reason (guarantee of consistent slice, avoiding re-typing differences or forgetting a section). It also explains when to override default query parameters (for a different slice) and notes that defaults are sensible for a first-cut report. This is excellent guidance with explicit alternatives.

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