get_stats

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

No annotations exist, so the description carries the full burden; 'Get' implies a read-only, zero-side-effect operation and the mention of 'dataset version' hints at data vintage. However, it says nothing about whether figures are cached or live, how often they refresh, or the cost/latency of the call.

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 sentence that front-loads the verb and resource and then enumerates returns with a colon list. No filler or redundancy.

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 usefully enumerates the returned statistics (domain count, category breakdown, version), which is what an agent most needs. The only gap is behavioral context around freshness and whether the summary is cached.

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 tool takes no parameters and the schema is an empty object, so baseline 4 applies. The description correctly adds no parameter discussion, since there is nothing to parameterize.

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 concrete verb ('Get') and resource ('summary statistics') and enumerates the three returned fields, so an agent knows exactly what comes back. It does not explicitly distinguish itself from get_categories, which is the closest sibling and could plausibly be confused with the 'per-category breakdown' portion.

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 call this versus alternatives such as get_categories or search_domains, and no prerequisites or exclusions are given. Usage is only inferable from the fact that it returns an overview.

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