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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It states 'Retrieves', implying a read-only operation, but does not explicitly confirm idempotency, rate limits, or whether the operation has side effects. No details about pagination, data limits, or error conditions are given.

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 sentence, which is concise, but it is overly terse and lacks front-loaded structure that conveys key information efficiently. It could benefit from additional context without becoming verbose.

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 presence of an output schema, the description does not need to explain return values. However, it fails to clarify what 'query statistics' entails, how data is grouped by device, or any constraints. The description is too minimal to provide adequate context for the agent to reliably use 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 description coverage is 100%, so the input schema already describes all three parameters. The description adds no additional meaning or context about the parameters beyond what the schema provides. Thus, it meets the baseline but does not exceed it.

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 uses a specific verb 'Retrieves' and resource 'query statistics by device', which clearly indicates the tool's function. It avoids tautology by adding 'query statistics' beyond the tool name. However, it does not explicitly differentiate from the sibling tool 'getAnalyticsDevicesSeries', which likely returns time-series data, leaving ambiguity about whether this returns aggregated data.

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?

The description provides no guidance on when to use this tool versus alternatives like 'getAnalyticsDestinations' or 'getAnalyticsDevicesSeries'. There is no mention of prerequisites, context, or exclusion conditions, leaving the agent to guess based solely on the tool name.

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