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

With no annotations provided, the description carries the full burden, yet it says nothing about read-only behavior, permissions, pagination, result size, or what the browse operation returns. "Browse" weakly implies a non-mutating traversal, which is the only behavioral clue offered.

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 a single short, front-loaded phrase with no filler, but it is under-specified rather than efficient — brevity here costs the agent essential information about the required path argument.

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 tool with a mandatory, undocumented parameter, no annotations, and no output schema, the description should explain the path format and roughly what a listing returns. Neither is present, so an agent cannot reliably invoke this tool.

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% and the single required parameter `path` is completely unexplained in both schema and description. The words "categories and tables" hint that path is a hierarchical category path, but the agent gets no format, root value, or example to construct a valid call.

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?

"Browse Finnish statistics categories and tables" names a resource domain, but "browse" is vague about the actual operation and the phrase conflates categories with tables, leaving it unclear whether the tool returns categories, tables, or both. It gives no explicit differentiation from the siblings get_table_data and get_table_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_table_data or get_table_metadata, no prerequisites, and no exclusions. The only implicit signal is that listing presumably precedes fetching metadata or data.

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