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

Goes well beyond the annotations: states preconditions and that it reports what is missing, discloses the 30-day private download link, explains that each call regenerates at current values while a repeat within minutes returns the same report (matching idempotentHint=true), and draws explicit scope boundaries (not a loan decision/pre-approval, does not move, convert, or reserve crypto). This is the kind of operational and safety context annotations cannot carry.

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?

Front-loads what the report is, then prerequisites, then return behavior, then limits — a sensible information hierarchy. The prose is dense with no filler sentences, though it is on the longer side for a no-parameter call.

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?

An output schema exists and the description still covers preconditions, regeneration/idempotency nuance, link lifetime, and explicit non-goals. Nothing an agent needs to decide whether and how to call this tool is missing.

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 takes zero parameters, so per the rubric the baseline is 4. The description adds no parameter discussion, which is appropriate since there is nothing to document and the schema is empty.

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?

States a specific verb and resource ('Creates the user's RealScore Report') and then defines precisely what the artifact is and contains (identity, verified wallets, holdings, balance history, conversion adjustment). An agent can tell what it produces without opening the schema. It never names the closest sibling, generate_proof_of_funds, so explicit sibling differentiation is missing.

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?

Gives clear triggering context ('the asset verification document a buyer gives a mortgage lender when the down payment or reserves come from crypto') plus hard prerequisites (verified identity, at least one verified wallet). What is absent is any when-to-use-this-vs-that guidance relative to generate_proof_of_funds or the other wallet/verification tools.

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