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

No annotations are supplied, so the description carries the full burden. The phrase 'your paper loan account' implies a personal, likely read-only snapshot, but the description does not explicitly confirm read-only behavior, authentication requirements, or any side effects. It adds some behavioral context by listing the returned categories.

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 compact sentence leads with the account concept and then lists the returned data. It is efficient overall, though the parenthetical is slightly awkward and the sentence lacks a clear verb.

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 tool with no output schema, the description outlines the returned categories but does not specify exact fields, response shape, or behavior on missing or invalid tokens. It is adequate but leaves clear gaps for an agent preparing to call it.

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?

There is one parameter with zero schema description coverage. The description's '(wallet token)' clarifies that the token is a wallet authentication credential, which adds meaning beyond the schema. However, it does not state whether the parameter is required, optional, or how the token is obtained.

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 identifies the resource as the caller's paper loan account and enumerates its contents: paper balance, loans as lender and borrower, and repaid/defaulted history. This distinguishes it from marketplace-oriented siblings like loan_board and loan_offer. It lacks an explicit action verb such as 'view' or 'get', but the purpose is still clear.

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 loan_board, loan_offer, loan_take, loan_repay, or loan_cancel. The agent must infer from the name and sibling list that this is a personal account snapshot. It also does not state whether the wallet token is required for access.

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