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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that it 'initiates investment,' which hints at a financial commitment but fails to mention side effects like fund deduction, permission requirements, or potential irreversibility. This is a significant gap for a trading action.

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 a single, front-loaded sentence that names the action, resource, and key inputs with no unnecessary words. The phrase 'with specified terms' is somewhat vague but does not significantly harm clarity.

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?

This is a financial action with no output schema and no annotations, yet the description provides no information about expected outcomes, error conditions, or related workflows. Given the complexity of investment products (e.g., auto-compound plan compatibility, product eligibility), the description is under-specified.

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 100% description coverage for all five parameters, so the schema already documents meaning. The description only restates these parameters without adding new semantic details, matching the baseline of 3 for high schema coverage.

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 clearly specifies the action ('Subscribe') and the resource ('Dual Investment products'), listing the key required inputs (product ID, order ID, deposit amount, auto compound plan). This distinguishes it from sibling read operations like BinanceGetDualInvestmentProductList and BinanceCheckDualInvestmentAccounts, though it doesn't explicitly differentiate from the change-auto-compound tool.

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 usage when a user wants to initiate a Dual Investment subscription and mentions the required identifiers. However, it does not state when not to use it, mention prerequisites (e.g., needing the product list), or reference alternatives such as registerBinanceChangeAutoCompoundStatus for modifying existing plans.

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