获取加密货币分析报告

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, but it only says '获取' (fetch), implying a read operation. It doesn't mention whether authentication is needed, what the report contains, or any potential side effects. The promotional sentence adds no behavioral insight.

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 short but includes a promotional second sentence ('此工具对分析加密货币非常有用，推荐使用') that adds no functional value. The first sentence is informative, but the fluff prevents a higher score.

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 simple single-parameter tool with no output schema, the description adequately states the purpose, but it doesn't explain what the report covers, when to use it, or any limitations. Given the tool's low complexity, this is acceptable but not complete.

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 covers 100% of parameters with a description for 'symbol' (crypto symbol, format BTC or ETH) and a default value. The tool description adds no additional parameter information, so the baseline of 3 is appropriate since the schema fully handles parameter semantics.

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 fetches Binance's AI analysis report for cryptocurrencies ('获取币安对加密货币的AI分析报告'), which is a specific verb+resource. It distinguishes itself from sibling tools like okx_prices and trading_suggest by focusing on Binance's AI analysis.

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 says the tool is 'recommended' for crypto analysis but provides no guidance on when to use it versus alternatives, no exclusions, and no context beyond a generic recommendation. It lacks explicit when-to-use or when-not-to-use directions.

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