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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered, but the description adds nothing beyond that. It does not say whether the listing is paginated, how versions are ordered, whether it includes deleted/restored versions, or what identifiers a version has (which matters because restore_article_version presumably consumes one).

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?

It is a single short sentence with no filler, so it is not bloated, but its brevity comes from under-specification rather than efficiency. There is no front-loaded scope statement beyond the obvious.

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 list-type tool with no output schema, the description carries the burden of explaining result shape, ordering, and pagination, and it does none of these. The minimum an agent needs to call this correctly and interpret the response is absent.

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% for the single articleId parameter, so the schema already carries the parameter documentation; baseline 3 applies. The description's phrase 'of an article' only loosely reinforces that the ID identifies the parent article and adds no format or sourcing detail.

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 sentence gives a clear verb and resource (list versions of an article) but is essentially a restatement of the tool name and title, adding no distinguishing information. An agent can tell it apart from list_articles or get_article only by relying on the name, not on anything the description contributes.

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 guidance on when to use this instead of get_article, list_articles, or restore_article_version, and no prerequisites or exclusions are stated. The agent must infer the appropriate context entirely from the tool name.

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