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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description does not need to repeat those. It adds valuable behavioral context with the warning that 'Mixed-asset totalAmountReceived is not fiat revenue,' which helps the agent interpret results correctly. This goes beyond structured annotations.

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 two short sentences with no filler. The primary purpose is front-loaded, and the caveat is placed second where it can prevent misinterpretation without obscuring the main function.

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 zero-parameter read-only tool with an output schema and safety annotations, the description is sufficiently complete. The purpose is clear, and the caveat about totalAmountReceived addresses the most likely point of confusion in the returned statistics.

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 zero parametersaint, so there is no parameter semantics burden for the description to carry. The baseline of 4 applies because no parameter documentation is needed at all.

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?

Description states a clear verb-resource pair: 'Read dashboard request counts and statistics.' This is specific enough to separate the tool from general payment or account tools, though it does not explicitly contrast it with similar reporting siblings like auraspay_payments_report or auraspay_payments_analyze.

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 guidance on when to use this tool versus alternatives such as payments_report, payments_analyze, or ecosystem_overview. The read-only nature is implied by 'Read,' but no explicit context, exclusions, or alternative routing is provided.

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