Check Trade Intent Against Policy

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

With no annotations provided, the description carries the burden of behavioral disclosure. It does explain the tool evaluates policy caps and is a pre-execution gate rather than the actual trading action. However, it does not disclose what happens when a cap is exceeded, whether the call has side effects, or what the returned result signifies.

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 long, front-loads the core purpose, and immediately gives the critical usage instruction. Every sentence adds value, and there is no redundant or vague phrasing.

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?

The input side is well covered by the schema and all three parameters are required. However, there is no output schema and the description does not explain what kind of result this tool returns or how an agent should interpret it when deciding whether to proceed with the trade.

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?

Schema description coverage is 100%, so the parameters are already fully documented in the schema. The description adds no parameter-specific detail beyond indicating the trade context, which matches the baseline expectation 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 states the tool's specific action — evaluating a proposed Binance trade against per-transaction and daily cumulative spend caps — and distinguishes it from executing the trade itself. The verb "Evaluates" plus the targeting of a specific resource makes the purpose unambiguous.

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 gives an explicit when-to-use instruction: "Call this BEFORE calling any Binance MCP trading tool." It does not directly mention alternatives or exclusions, but the placement guidance is strong and leaves little doubt about the intended call order.

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