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

No annotations exist, so the description carries the burden, and it does disclose the return payload in useful detail (codes, finish groups, opening directions, size ranges, reference price for 800x2000, product-card links, 3D files). However, it says nothing about read-only nature being explicit, pagination, or how large the list is, leaving meaningful behavioral gaps for a no-annotation tool.

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 sentence with no filler, and the core purpose is front-loaded before the enumeration of returned fields. The content list is long but each item earns its place by telling the agent what comes back.

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 must describe the return shape, and it does so with a concrete field list including the reference price basis (800x2000). Combined with the zero-parameter schema, an agent has enough to call and interpret the tool, though usage context is thin.

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?

The schema has zero parameters, so there is nothing to disambiguate; the baseline for a parameterless tool is 4. The description correctly implies no filtering input is accepted (an unfiltered full list).

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 clear verb+resource ("Список моделей скрытых дверей") and scopes it to the Invisible Doors aluminum-frame line, so an agent knows exactly what entity is listed. It also previews the returned fields. It does not explicitly name a sibling it differs from, so it stops short of a 5.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives such as find_partitions, get_codes, or quote_door. The agent must infer that this is the catalog-lookup entry point versus the quoting tools from the name alone.

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