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

No annotations are provided, so the description carries the full behavioral burden and largely fails: it does not state that this is a read-only lookup, what data source or coverage it searches, latency/cost characteristics, or how the ranking is derived. It only names the shape of the result.

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 tight sentence with the key output information front-loaded and no filler. It loses a point only because the fragmentary structure omits an action verb, making it read as a return-value caption rather than a tool description.

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 annotations, no output schema, and no parameter descriptions, the description is expected to do more. It never explains usage conditions, input constraints, or behavioral properties, so an agent has enough to recognize the tool's domain but not enough to invoke it confidently.

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%, so the description must compensate. It implicitly covers only 'invention_description' by naming it, and says nothing about the jurisdiction parameter (US/EP/WO enum) or the 20-4000 character input bound, leaving roughly half the parameters undocumented.

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 phrase names the resource (patents) and the two outputs (ranked closeness list plus claim-overlap summary) so an agent knows what the call produces. However it is a noun phrase with no verb and does not differentiate itself from siblings like compare_claims or landscape_summary, which also operate on patent text.

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?

There is no when-to-use guidance at all, no indication of when to prefer compare_claims or landscape_summary, and no stated prerequisites or limits. The agent must infer context purely from the name.

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