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 API-key requirement (file generation), the output artifact (ZIP with a link), and the fact that the cart must match the one used for calc_nmck_cart. It does not cover failure modes, cost, or latency, but the safety/auth/output profile is well above the annotation-less baseline.

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?

A single dense paragraph with the deliverable list front-loaded and the sibling routing after it; nearly every clause carries new information. It is somewhat run-on but no sentence is wasted.

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?

With no output schema, the description compensates by enumerating the generated files and the ZIP-with-link return. Combined with the auth requirement and the calc_nmck_cart sequencing, an agent has everything needed to call it correctly.

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 cart/name/phone are already documented. The description adds only marginal semantics (articles come via find_product, cart is arbitrary and must match the NMCK cart), which is the expected baseline when the schema does the heavy lifting.

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 (собрать) and resource (полный тендерпакет 44/223-ФЗ) plus exact deliverables (КП, ТЗ, обоснование НМЦК, спецификация xlsx, проект контракта, опись → ZIP). The parenthetical 'не только раздевалки' carves out its scope against the sibling make_tender_package, so an agent can distinguish them without opening schemas.

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?

Explicitly prescribes the workflow: pair with calc_nmck_cart — compute NMCK first, then assemble the package for the same cart. Also routes article lookup to find_product. Both the prerequisite ordering and the sibling dependencies are spelled out rather than implied.

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