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

Annotations already cover the safety profile (readOnlyHint, destructiveHint=false, openWorldHint=false), yet the description still adds ordering behavior and a concrete inventory of returned fields versus the omitted body. Only 'Read only.' merely restates the annotations.

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?

One dense, front-loaded sentence carries scope, ordering, filter and return shape; the trailing 'Read only.' is redundant with readOnlyHint and is the only wasted clause.

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?

With no output schema, the description compensates by enumerating the row fields and flagging that the body is excluded. It leaves unaddressed what happens when more than limit (max 50) articles exist, since there is no offset/cursor parameter.

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%, so the three parameters are already documented. The description reinforces that domain_id scopes to a single domain and repeats the status enum values, but adds no new syntax or limits (e.g. that limit is capped at 50) beyond the schema.

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?

States a specific verb and resource (list articles), scopes it to one domain, declares ordering (newest first), and names the optional status filter. It is clearly distinguishable from get-article (single, full body) and the other list-* siblings.

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 status filter values and 'newest first' ordering make the intended browsing use case clear, and the note that rows exclude the body implicitly routes the agent to get-article when full content is needed. It stops short of explicitly naming that alternative or stating exclusions.

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