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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive, so 'Public read-only' largely restates structured data. The one piece of genuine added value is the pagination instruction ('Paginate with cursor'), which tells the agent the result set is paged, but it stops short of stating page size, default limit, or ordering.

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?

Three short, front-loaded sentences with no filler. 'Public read-only' is mildly redundant against the annotations, but the overall signal-to-length ratio is good.

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 public read tool with no output schema and annotations covering safety, the essentials are nearly covered, but the description never indicates what an article record contains or how results are ordered, and limit remains unspecified. Just adequate rather than complete.

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%, so the description carries the burden for two parameters. It explains cursor's role ('Paginate with cursor') but says nothing about limit — no default, maximum, or behavior when omitted — leaving half the parameters undocumented.

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 (List) and resource (published Farm Times / community_news articles), which is enough for an agent to identify the operation. It does not differentiate from close siblings like list_farm_times_headlines or get_farm_times_article, so the boundary between 'articles' and 'headlines' is left to inference.

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 explicit when-to-use guidance and no mention of alternatives, despite at least two closely related siblings (list_farm_times_headlines, get_farm_times_article). 'Public read-only' hints at context but is a property, not usage direction.

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