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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds one useful behavioral fact beyond that — the article must be *public*, implying no authentication or paywall bypass. It says nothing about rate limits, failure behavior for non-Axios URLs, or whether content is truncated.

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?

A single tight sentence that front-loads both the resource and the payload. There is no waste, though it is a noun phrase rather than a directive sentence, which slightly weakens the framing.

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?

An output schema exists, so return-value detail is not required. However, for a tool whose only input is a URL with 0% schema coverage and no sibling guidance, the description leaves the essential question — what kind of URL is valid — unanswered.

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 0%, and the single `url` parameter has no documented format anywhere. The description implies the URL should point at an Axios article, which is marginally useful, but it does not state whether arbitrary URLs are accepted or rejected, or whether the URL must be absolute.

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 names the specific resource (a public Axios article) and states exactly what is returned: metadata plus full body paragraphs. That content scope cleanly separates it from siblings like axios_headlines and axios_categories. It lacks an explicit verb ("fetch"/"get"), but the resource and payload are unambiguous.

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 when-to-use statement and no reference to any sibling. An agent is not told to use axios_headlines first to discover article URLs before calling this tool, nor when this tool is preferable to axios_categories. Usage must be inferred entirely from the name.

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