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

No annotations are provided, so the description carries the burden. It describes the tool as 'live feed' but does not mention authentication, rate limits, or whether results are cached or streaming. Adequate but not detailed.

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?

Two sentences, no filler. The first sentence states purpose and return fields. The second adds optional filtering and use case. Every sentence is informative and earns its place.

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?

Given 4 parameters, no output schema, and no annotations, the description provides a solid overview and key parameter hints. It lacks details on pagination, ordering, or limitations, but is fairly complete for a simple real-time feed tool.

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 50% (topic and namespace have descriptions). The description adds meaning for 'topic' by specifying it does substring match against title and edit comment. It also mentions 'exclude_bots' but does not elaborate beyond the schema default. Overall, it adds value beyond 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?

The description clearly states the tool provides a 'live feed of recent edits to English Wikipedia' and lists the return fields (title, editor, timestamp, comment, size delta). This uniquely distinguishes it from sibling tools like wikidata_search, wiki_page_summary, and wiki_trending.

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?

It explicitly states usefulness for 'trend-monitoring or news-monitoring agents' and mentions that breaking news events appear in edits quickly. It does not explicitly exclude alternatives, but the use case is clear.

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