get_echojs_latest

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

No annotations are provided, so the description must carry the behavioral burden. It does not mention caching behavior, rate limits, authentication, or what the return data looks like beyond being news.

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 two sentences, immediately stating the tool's purpose and then listing typical use cases. No redundant or irrelevant information.

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 news-fetching tool with no output schema, the description is mostly adequate. However, it does not describe the structure of the returned data (e.g., titles, links), 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?

Schema description coverage is 100% for the two parameters. The description adds context about the tool's domain but does not add meaning beyond what the schema already provides for parameter formats or syntax.

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 it fetches the latest JavaScript/front-end news from Echo JS, specifying the resource and type of content. It distinguishes from 'get_echojs_top' by using 'latest', but does not explicitly contrast with that sibling.

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?

It provides a list of topics (React, Vue, etc.) indicating appropriate use cases, but does not mention when not to use it or alternatives like 'get_echojs_top'.

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