get_arstechnica_feed

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states content ('Tech news from Ars Technica') but does not indicate that the tool performs a read-only operation, returns a feed, or any other behavioral traits. The description is a noun phrase, not a statement of behavior.

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?

The description is extremely brief and front-loaded, using only four words. It contains no fluff and is easily scannable. However, its brevity borders on under-specification, though it does convey more than a tautology.

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?

The tool has no annotations, no output schema, and zero parameters, so the description is the sole source of context. It fails to explicitly state what the tool does (e.g., 'Fetches the latest Ars Technica news feed'), leaving the agent to infer from the name. Given the sibling tools, the description is insufficient for complete understanding.

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?

The input schema has zero parameters, and the baseline for 0 params is 4. The description need not add parameter semantics since there are none; the schema fully covers the empty parameter set.

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 'Tech news from Ars Technica' provides a resource (Ars Technica) and content type (tech news), but lacks a clear verb specifying the action. It is not a tautology because it adds context, but it fails to explicitly state that the tool fetches or returns a feed, making it ambiguous compared to sibling tools like fetch_rss or get_tech_feed.

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 description offers no guidance on when to use this tool versus alternatives. With sibling tools such as get_tech_feed and get_news_feed, there is no distinction or conditional advice, leaving the agent without context for selection.

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