get_v2ex_hot_topics

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It states 'Get hot topics' but does not reveal whether the operation is read-only, if caching is applied (though use_cache parameter hints), or any rate limits, auth requirements, or side effects. Minimal transparency beyond the basic 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?

Two sentences, no wasted words. The first sentence states the core purpose, and the second adds context. Highly concise and front-loaded.

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?

No output schema is provided, and the description does not mention what fields are returned (e.g., title, link, score). It also lacks details on pagination, rate limits, or authentication. Given the tool returns a list of topics, the description is incomplete for an agent to understand the full response.

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 coverage is 100%, with descriptions for both parameters: limit and use_cache. The tool description adds no additional meaning or constraints beyond the schema. For example, it does not explain the default values or trade-offs of using cache. Baseline of 3 is appropriate as schema does the heavy lifting.

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 action ('Get') and resource ('hot topics from V2EX Chinese community'). It distinguishes from sibling tools by specifying the unique community (V2EX) and topic scope (tech and creative). However, it could be more precise about what defines 'hot' (e.g., sorted by popularity or recent activity).

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?

No explicit guidance on when to use this tool versus alternatives. The description implies usage for retrieving V2EX hot topics but does not compare with similar siblings like get_hackernews_stories or get_echojs_latest. There are no prerequisites or exclusions mentioned.

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