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

Annotations already establish this as a safe read-only operation, so the bar is lower. The description adds the useful fact that the payload covers tokens, improvements, and plan limits, but says nothing about scope (org vs customer), refresh cadence, or what happens when the optional customerId is supplied.

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?

A single efficient sentence with the resource front-loaded and no filler. It could be tightened only marginally.

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?

For a one-parameter read with annotations carrying the safety profile, the definition is serviceable. However, with no output schema the reader has only a three-item hint about the return payload, and nothing explains the superadmin/on-behalf-of flow beyond the schema text.

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% and the single customerId parameter is fully documented in the schema, including the superadmin restriction. The description adds no parameter-level meaning, so the baseline 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 gives a specific verb ('Get') and resource ('current usage statistics') and enumerates the content categories (tokens, improvements, plan limits). It is distinguishable from most siblings, though it never names its nearest neighbors (get_account, get_settings, get_converra_roi).

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?

There is no when-to-use guidance, no exclusions, and no routing to alternatives among the many get_* siblings. 'Current' hints at real-time scope but leaves the agent to infer the rest.

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