get_usage_stats

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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses nothing: no auth requirements, no pagination, no rate limits, no return shape. A read of "stats" is implied only by the name.

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 text is brief, but brevity here is under-specification rather than conciseness — there is no front-loaded scope, qualifier, or actionable detail in the single fragment.

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 an opaque nested body object, no annotations, and no output schema, the description should define scope, required payload, and response expectations. None of that is present, so an agent has no basis for correct invocation.

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?

There is one parameter, an empty-bodied 'body' object with additionalProperties=true and 0% schema description coverage. The description provides no field names, formats, or filtering semantics to compensate, leaving the agent with nothing to construct a call from.

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?

"Get usage stats" merely restates the tool name; it names no specific resource scope, metric type, or time window. With siblings like get_language_stats and get_agent_stats in the same family, an agent cannot tell what dimension of usage this tool covers. It is effectively a tautology.

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, when-not-to-use, or alternative routing is provided. The agent gets no signal to distinguish this from get_language_stats, get_agent_stats, or any of the history tools.

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