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

With no annotations, the description discloses non-obvious traits: curation ('curated') and freshness ('refreshed every weekday morning'). It does not detail data range (e.g., historical availability) or authentication needs, but provides reasonable transparency for a simple news retrieval tool.

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 a single, front-loaded sentence efficiently conveying source, content, and update frequency with no redundancy.

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 tool with one optional parameter and no output schema, the description covers source and refresh schedule. It could mention that it returns only the most recent items (implied by 'latest') but is otherwise 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 coverage is 100% for the single 'limit' parameter, which has a clear description including default and max. The tool description does not add extra meaning beyond the schema, so baseline 3 is appropriate.

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 clearly specifies the verb ('get'), resource ('latest curated GenAI news items'), source ('AI-Portal'), and refresh frequency ('every weekday morning'), distinguishing it from siblings like list_regulations and list_releases.

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 implies the tool is for obtaining current news due to the 'latest' and 'refreshed every weekday morning' wording. However, it does not explicitly state when not to use it or mention alternatives like search_glossary, but sibling names provide enough context for differentiation.

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