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

No annotations are provided, so the description carries the full burden. It discloses that the call is a read/lookup returning rich structured detail including a ready-to-call hasdataLink, and it describes what the response contains. It doesn't mention rate limits, auth, or pagination, but for a read lookup this is largely sufficient.

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?

Front-loads the purpose, then details identifier provenance and return contents in two dense sentences. Every sentence earns its place, though the return-contents sentence is long and could be trimmed.

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 compensates by enumerating what is returned (title, parties, court, dates, citations, cited cases). No annotations exist, yet the read-only nature and return shape are conveyed, leaving only minor gaps like error handling.

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 100%, so the schema already documents both parameters, giving a baseline of 3. The description adds value by explaining where caseId comes from and what a valid caseId looks like, going beyond the schema's terse definition.

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 (get/lookup) and resource (Scholar Case Law opinion) and names the exact identifier (caseId). It also clarifies the retrieval context relative to how caseId is obtained, distinguishing it from sibling search and citation tools.

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?

Explains how to obtain the caseId and mentions intended use cases (legal-research workflows, walking a citation graph). It doesn't explicitly name the sibling tools as alternatives, but the context is clear enough to route the agent correctly.

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