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. It discloses the source offices and searchable fields, but does not describe result limits, pagination, return format, or authentication/rate-limit behavior for this search tool.

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?

The scope is front-loaded and the exclusion guidance is useful, but the second sentence largely restates the first sentence's list of offices and fields. Some redundancy could be removed without losing meaning.

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?

For a one-parameter search tool with no output schema or annotations, the description covers sources, searchable fields, and sibling exclusions well enough to select and invoke it. Return-shape and pagination details are absent but less critical given the simple invocation model.

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 100%, so the single parameter is already well documented in the schema. The description adds domain context about what can be searched but does not add syntax or format guidance beyond the 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?

States a specific verb and resource (search patent grants/applications) and enumerates the patent offices and data fields covered. It clearly distinguishes itself from sibling tools for trademarks and legal precedents.

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?

Explicitly says when to use it and when not to use it, naming the alternative sibling tools lookupTrademarkAvailability and searchLegalPrecedents for adjacent domains. The routing conditions are unambiguous.

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