getAnalyticsIPsSeries

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

No annotations are provided, so the description carries the burden. It states the tool retrieves data, implying a read-only operation, but does not explicitly disclose non-destructive behavior, rate limits, or other traits. With an output schema present, the baseline is acceptable but adds no extra transparency.

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 of 10 words that directly states the tool's purpose. It is front-loaded and contains no filler. Every word is earned.

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. It adequately covers the purpose and context (charting). However, it could add more detail about time-series granularity or constraints, but it is sufficient for a tool with many similar siblings.

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%, meaning all parameters (profile_id, from, to) are already described in the input schema. The description does not add any additional parameter-level meaning beyond what the schema provides, so the baseline of 3 applies.

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 it retrieves time-series statistics about client IP addresses for charting. The verb 'Retrieves' and the resource 'client IP addresses' are specific, and it is distinct from other getAnalytics*Series siblings that focus on different metrics (e.g., destinations, devices).

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 does not provide explicit guidance on when to use this tool versus alternatives like getAnalyticsIPs or other series tools. Usage is implied by the tool name and description, but no when-not-to-use or alternative suggestions are given.

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