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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the tool autocompletes names (returning suggestions), which is useful, but says nothing about how the field/value inputs behave or what the suggestions look like beyond the output schema.

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 no waste, stating verb and scope immediately. It is efficient, though its brevity leaves the param semantics under-explained.

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?

The tool is a simple 2-param autocomplete with an output schema, so return values need not be described. However, with zero schema description coverage, the ambiguity of the field/value parameters is a meaningful gap the description does not close.

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 0% for both required params, so the description carries the burden. It names the two domain concepts ('inventor or assignee'), which likely maps to the 'field' parameter's expected values, but it never explains the field/value pair structure or that value is a partial name prefix.

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 (autocomplete) and resource (inventor or assignee name) scoped to Google Patents, which distinguishes it from the sibling googlepatents_search. It doesn't explicitly name that sibling, but the autocomplete framing is clear enough to differentiate.

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 phrase 'for Google Patents search' implies this is a pre-search helper for resolving names, but there is no explicit when-to-use, no when-not-to-use, and no named alternative (e.g. googlepatents_search). Usage must be inferred.

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