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 states what the tool returns ('网络日志数据') but doesn't describe format, structure, or content of the logs. It also doesn't mention whether this requires specific permissions, has rate limits, or depends on other tools being called first (like enabling network monitoring).

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 appropriately concise with a clear purpose statement followed by structured Args and Returns sections. Every sentence serves a purpose: the title explains what the tool does, and the parameter/return documentation provides essential information without unnecessary elaboration.

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?

Given that there's an output schema (which handles return value documentation), the description doesn't need to explain return values in detail. However, for a tool that fetches network logs with no annotations, the description should ideally mention dependencies (like needing network monitoring enabled) or format expectations. It's minimally adequate but has clear gaps.

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 description explicitly documents the single parameter 'limit' and explains its purpose ('返回日志的最大数量'), which adds meaningful context beyond what the schema provides (schema description coverage is 0%). Since there's only one parameter and it's fully explained in the description, this earns a high score despite the schema's lack of descriptions.

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 purpose as '获取网络请求日志' (get network request logs), which is a specific verb+resource combination. However, it doesn't differentiate this tool from potential sibling tools like 'enable_network_monitoring' or 'run_cdp_command' that might also interact with network data, so it doesn't reach the highest score.

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 provides no guidance on when to use this tool versus alternatives. There are no explicit instructions about prerequisites (like needing network monitoring enabled first), timing considerations, or comparisons to sibling tools such as 'enable_network_monitoring' or 'run_cdp_command' that might handle network data differently.

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