stock_js_weibo_nlp_time

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

Annotations declare readOnlyHint true, destructiveHint false, and idempotentHint true, but the description adds no behavioral context beyond that. It does not mention data source behavior, rate limits, side effects, or any operational traits, despite the URL hinting at a data center endpoint.

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 extremely short but under-specified. It contains only a URL and a return-type line, which do not earn their place as a meaningful description. The brevity is not purposeful conciseness but a lack of substantive content.

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 the cryptic name and lack of output schema, the description is completely inadequate. It fails to explain what the tool does, what data it retrieves, or what 'specific time representation' means, leaving the agent unable to use it correctly.

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 tool has zero parameters, so the baseline is 4 per the rubric. The description does not need to explain parameter semantics since there are none to document; the empty schema already fully covers this.

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 provides only a URL and a return type ('dictionary representing a specific time'), with no verb or resource indicating what the tool actually does. The name 'stock_js_weibo_nlp_time' is cryptic, and the description does not clarify its function or distinguish it from any of the many sibling tools.

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 alternatives. The description contains no context about scenarios, prerequisites, or exclusions, leaving the agent completely without direction for selection.

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