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

No annotations are provided, so the description carries the full behavioral burden. 'Отримати' implies a read, but the description says nothing about failure behavior for an unknown code, permissions, or what is returned.

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 short sentence with the resource and lookup key front-loaded and no wasted words. It is efficient, though minimalism here partly reflects missing content rather than tight editing.

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 simple one-parameter lookup with no output schema, the description is minimally adequate, but it omits return shape, not-found behavior, and any code-format expectation that would let an agent call it reliably.

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 0%, so the description must compensate; it does add that the single parameter is a КАТОТТГ code (a Ukrainian territorial-classification identifier), which is more than the bare 'Code' in the schema. However it gives no format, validation, or example details.

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 (Отримати) and resource (територію) plus the lookup key (кодом КАТОТТГ), so the agent knows it is a by-code lookup. It does not distinguish itself from siblings list_territories or search_territories, which also return territories.

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 guidance on when to use this versus list_territories, get_hierarchy, or search_territories, nor any stated preconditions. Usage must be inferred entirely from the name.

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