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

With no annotations provided, the description carries the burden of behavioral disclosure. It explicitly states "all" (implying no scoping or filters) and "with lawyer counts" (revealing a key aspect of the return content). However, it does not discuss whether the operation is read-only, potential error cases, or any rate limits. The verb "List" suggests a safe read-only operation, but this is not stated explicitly.

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 description is a single, concise sentence that immediately states the action and expected output. There is no extraneous information or repetition. It is well-structured and front-loaded, making it easy for an agent to quickly grasp the tool's function.

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?

Given the tool's simplicity (no parameters, no output schema, no annotations), the description provides sufficient information about what the tool returns (practice areas with lawyer counts). It does not elaborate on the exact return format (e.g., array vs. objects), but for a basic list operation this is acceptable. Sibling tools offer enough context to infer that this is a general list endpoint, and the description covers the core purpose without requiring additional detail.

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?

The input schema is empty with zero parameters, so the schema coverage is effectively 100%. According to the rubric, 0 parameters earns a baseline of 4, and the description does not need to explain parameter semantics. The description adds value by clarifying that the result includes lawyer counts, which is helpful context for the return value.

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 clearly states the tool's purpose with a specific verb ("List") and resource ("practice areas"), and adds scope ("all") and content detail ("with lawyer counts"). This distinguishes it from siblings like get_lawyer_profile and search_lawyers, which focus on individual lawyers or searches.

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 provides no guidance on when to use this tool versus alternatives. It does not mention when one would prefer this over get_jurisdictions or other siblings, nor any exclusions or prerequisites. The only implied context is that it returns practice areas, but there is no explicit usage direction.

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