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

Annotations already declare readOnlyHint, idempotentHint, non-open-world and non-destructive, so the safety profile is fully covered structurally. The description adds useful behavioral context by naming the return payload (citation URLs, stable article IDs), but says nothing about pagination, rate limits, or result 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?

A single front-loaded sentence with zero filler that states both the resource searched and the return shape. Nothing is padded or redundant.

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?

No output schema exists, and the description partially compensates by naming return fields. However, with zero schema description coverage on three parameters and no pagination guidance for limit/offset, an agent still lacks enough to call the tool precisely.

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% and the description provides no meaning for query, limit, or offset beyond the word 'search'. The bounds and defaults exist only in the schema, so the description fails to compensate for the complete absence of parameter documentation.

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+resource (search published Vultax crypto/prediction-market studies) and what it returns (citation URLs and stable article IDs). It is distinguishable from get_research_article by being a search rather than a fetch-by-ID, though it does not name that 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 only implied: the fact that it returns 'stable article IDs' hints that search is the discovery step before get_research_article, but there is no explicit when-to-use, when-not, or alternative routing guidance. An agent can infer the workflow but must do the work itself.

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