getAnalyticsDestinationsSeries

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

No annotations provided, so the description carries the full burden. It does not disclose that the 'type' parameter filters by countries or GAFAM companies, nor does it mention the required profile_id or read-only nature. The description is too brief to inform agent behavior.

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?

One sentence, 12 words, very concise. However, it omits key details about parameters and filtering, making it slightly under-informative. Still efficient and front-loaded.

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?

Despite having an output schema, the description lacks important context: it doesn't explain the 'type' filter, the relationship to other series tools, or the required parameters. With no annotations and 4 parameters, the description is too minimal for complete guidance.

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 each parameter has a description in the schema. The tool description adds no additional meaning beyond the schema, meeting the baseline of 3.

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 verb 'retrieves' and the resource 'time-series statistics for the most queried destination domains for charting'. It distinguishes from sibling tools like getAnalyticsDestinations (non-time-series) and other series tools by focusing on destination domains.

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 implies usage for charting time-series data, but gives no explicit when-to-use or when-not-to-use compared to other analytics series tools (e.g., getAnalyticsDevicesSeries, getAnalyticsDomainsSeries). No alternatives or exclusions are mentioned.

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