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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description's 'Read' verb is consistent with those. The added clarification that provider capability is not completed KYC or issued cards provides useful domain context beyond the annotations, though it is slightly ambiguously worded.

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 sentences, front-loaded with the core read action and the data categories. The second sentence adds a valuable semantic caveat about provider capability, earning its place despite minor awkwardness.

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?

With no parameters, an output schema present, and annotations covering safety/idempotency, the description is nearly complete for an overview read tool. It names all major data areas and clarifies one ambiguous concept; the output schema can handle any remaining return-value detail.

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 tool has zero parameters, so the description carries no parameter documentation burden. The empty schema is fully covered, and the baseline for zero-parameter tools is 4; nothing is missing here.

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 uses a specific verb ('Read') and names concrete resources: receiving addresses, ownership proof status, wallet balances, and provider availability. It is clear about what the tool returns, though it does not explicitly distinguish itself from siblings like auraspay_account_balance or auraspay_dashboard_stats.

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 this is the broad overview/read tool by listing multiple ecosystem-level data points, but it gives no explicit when-to-use guidance or alternatives. For a zero-parameter overview tool, the implied usage is somewhat evident, but there are no exclusions or comparisons to sibling tools.

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