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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and world-scope are covered by structured data. The description adds the useful fact that only public articles are returned and that the payload includes body paragraphs, but says nothing about auth, rate limits, or what happens for non-existent/paywalled URLs.

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 with no filler, and the resource identity is front-loaded. It errs on the side of under-specification rather than verbosity.

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 values need not be enumerated, and the tool is a simple single-parameter fetch. However, with 0% parameter coverage and no usage routing, the definition is only minimally complete for an agent deciding whether to call it.

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% for the single required 'url' parameter, so the schema offers nothing. The description implies an article must be identified but never mentions the url parameter, its expected format, or that it must point at rawstory.com, leaving the one parameter undocumented in both places.

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 a specific resource (a Raw Story article) and states what is returned: metadata plus body paragraphs. It distinguishes itself from rawstory_headlines and rawstory_news by scoping to a single article, though it never names those siblings explicitly.

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 guidance, no instruction that a URL is required as the identifier, and no pointer to rawstory_headlines/rawstory_news as the alternative for discovering articles. The agent must infer the calling context from the name alone.

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