getAnalyticsProtocolsSeries

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. However, it only says 'retrieves time-series statistics' with no mention of rate limits, required permissions, data retention, pagination, or output format. The output schema exists but the description adds no context about what the data contains or how it is structured.

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 clear sentence with 11 words. It is front-loaded with the key information (retrieves time-series statistics) and the purpose (for charting). No unnecessary words or repetition.

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 tool's complexity (3 parameters, full schema coverage, output schema exists), the description is adequate but minimal. It lacks differentiation from many sibling series tools and does not clarify the required vs optional parameters. The output schema is present, so the description does not need to explain return values, but it could provide more context on the use case.

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% coverage with parameter descriptions. The tool description does not add any meaning beyond what the schema already provides. For example, it does not explain that 'to' defaults to now if omitted, or how 'from' and 'to' interact. Baseline 3 is appropriate given 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 clearly states the tool retrieves time-series statistics about DNS protocol usage for charting. It specifies the verb (retrieves), the resource (time-series statistics about DNS protocol usage), and the purpose (for charting). This distinguishes it from the sibling non-series tool getAnalyticsProtocols and other series tools like getAnalyticsDestinationsSeries.

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 minimal usage guidance. It implies the tool is for charting time-series data, but does not explicitly state when to use this tool versus alternatives like getAnalyticsProtocols (aggregated) or other series tools. No when-to-use, when-not-to-use, or alternative tool mentions.

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