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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'retrieve' which implies a read-only operation, but doesn't cover critical aspects like authentication needs, rate limits, error handling, or what the output format looks like (e.g., summary vs. detailed data). This leaves significant gaps for safe and effective use.

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, efficient sentence with no wasted words, making it easy to parse. However, it's overly brief and could benefit from more detail to improve clarity without sacrificing conciseness, as it currently under-specifies the tool's scope.

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?

Given the lack of annotations and output schema, the description is incomplete for a tool that likely returns complex statistics data. It doesn't explain what 'basic statistics' entails, how results are structured, or any behavioral constraints, making it inadequate for reliable agent operation without additional context.

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 input schema has 100% description coverage, with the 'group' parameter documented as 'Get statistics for specific box group'. The description adds no additional parameter information beyond this, so it doesn't compensate but also doesn't detract, meeting the baseline for high schema coverage.

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 'Retrieve basic statistics overview' clearly states the action (retrieve) and resource (statistics overview), making the purpose understandable. However, it lacks specificity about what 'basic statistics' includes and doesn't differentiate from sibling tools like 'get_statistics_by_box' or 'get_statistics_by_region', leaving ambiguity about scope.

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 guidance is provided on when to use this tool versus alternatives such as 'get_statistics_by_box' or 'get_statistics_by_region'. The description implies a general overview but doesn't specify use cases, prerequisites, or exclusions, leaving the agent to guess based on tool names alone.

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