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

readOnlyHint already establishes this is a safe read, and the description adds useful return-shape detail (titles, authors, summaries, links) that annotations cannot convey. However it says nothing about result caps, relevance ordering, or what happens when a query matches nothing.

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, zero filler, with the search scope front-loaded before the return-shape sentence. Nothing here could be cut without losing information.

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 helpfully enumerates the returned fields, so an agent knows what it will get back. The remaining gap is the undocumented limit/paging behavior, which matters for an agent deciding how many results to request.

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 only 50%: query is documented, but limit (default 8, max 20) has no schema description and no mention in the description. 'By topic or keyword' mildly reinforces query semantics but the description does not compensate for the undocumented limit parameter.

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 (Search) and resource (published World Innovation research abstracts and white papers) with the discovery axis (topic or keyword). It implicitly contrasts with get_paper/cite_paper/verify_paper by framing this as discovery rather than retrieval, but never names a sibling explicitly.

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?

Usage is implied: use this to find papers, then presumably use get_paper to read one. No explicit when-to-use/when-not-to-use or pointer to the sibling tools that would complete the workflow.

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