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. It implies a read returning a URL, but says nothing about permission requirements, what happens for an unknown or non-territorial code, or whether the address is stable/cached.

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 return type front-loaded; nothing is wasted. It is terse to the point of under-specification, but structure itself is sound.

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 one-parameter lookup with no output schema, the description does convey the return value (an HTTPS address). However, with zero annotation coverage and an undocumented required parameter, it leaves the agent guessing about input format and error behavior.

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 0% for the single required parameter 'code', so the description must compensate — and it does not. It never explains that 'code' is a territorial identifier, its expected format, or where to obtain it (e.g., from list_territories).

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 gives a specific verb+resource in Ukrainian: retrieve the HTTPS address of a territorial MCP. An agent knows exactly what is returned, but nothing distinguishes it from siblings like get_territory or get_catalog_info, which also fetch territorial metadata.

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 statement of when to use this tool versus get_territory, get_hierarchy, or search_territories, and no prerequisites (e.g., that a territory code must already be known). 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.
