get_echojs_top

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

No annotations are provided, so the description carries full disclosure burden. It only mentions 'most upvoted' but does not disclose caching behavior (use_cache parameter), rate limits, authentication requirements, or what happens on empty results. The description is minimal.

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 a single concise sentence with no extraneous words. It could be slightly improved by front-loading the source 'Echo JS' more prominently, but it is efficient.

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 fetch tool with two fully described parameters and no output schema, the description provides sufficient high-level context. However, it does not describe the return format or how to interpret results, which would be helpful.

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?

Both parameters (limit, use_cache) have schema descriptions with defaults and constraints. The tool description adds no additional meaning beyond the schema, so baseline 3 is appropriate.

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 retrieves top/trending/popular JavaScript news from Echo JS, specifying content type (most upvoted JavaScript and front-end). It distinguishes from sibling get_echojs_latest by focusing on top rather than latest.

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 implies usage for trending JavaScript news but lacks explicit guidance on when to use this tool versus alternatives like get_echojs_latest or other content sources. No when-not-to-use or comparative context is provided.

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