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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful context beyond the annotations: the data source (CourtListener), cryptographic attestation with a verification URL, and the $0.10 per-call cost.

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 core purpose is front-loaded in the first sentence, and the commercial/trust details (source, attestation, price) are packed efficiently. Slightly padded by the verification URL and pricing, but these earn their place as operationally relevant facts.

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 does a reasonable job describing the return content (citation counts, citing courts, authority signal). However, it omits how parameters should be supplied and what happens when none are provided, leaving a notable gap for a two-parameter, zero-required tool.

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 carries the full burden of explaining the two parameters, 'citation' and 'case_name'. It never mentions either field or how they relate (e.g., alternatives vs. both required), so an agent cannot tell which parameter to populate or whether a zero-parameter call is valid.

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 description names a specific resource (citation authority of a case) and the concrete outputs: citation counts, citing courts, and authority signal. It is clear about what the tool computes, though it does not explicitly differentiate itself from legal siblings like get_federal_case_law or get_case_law_synthesis.

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 description implies the tool is for citation authority analysis but gives no guidance on when to choose it over the many legal siblings in the list (e.g., get_federal_case_law, get_judge_analytics, get_docket_intelligence). There are no exclusions, prerequisites, or alternative routings.

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