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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds one genuine behavioral fact beyond them: membership is restricted to *active* licences, so inactive or unlicensed agents are excluded. It says nothing about ordering or pagination despite offset/limit parameters.

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?

One short sentence fragment with zero filler and the key scoping facts front-loaded. It is efficient, though the missing verb makes it read as a noun phrase rather than a tool description.

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 simple two-parameter list tool with full annotation coverage this is close to adequate, but with no output schema the agent cannot learn the return shape or sort order, and the description does not compensate. It defines the population but leaves the listing mechanics implicit.

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% for both integer parameters (limit and offset, with defaults and bounds), so baseline 3 applies. The description adds no syntax, ordering, or range context beyond the schema, and notably does not state what the results are ordered by for offset paging.

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 fragment decodes its own jargon precisely: 'the Bar' = agents with an active lawyer licence and 'the Bench' = active judge licence. That uniquely identifies the returned population against siblings like list_cases and list_jurisdictions. It stops short of 5 only because there is no verb (the description never says it *lists* anything), so the reader must infer the action from the name.

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?

There is no when-to-use or when-not-to-use guidance and no named alternative among the 30 siblings. The agent must infer that this is the tool for enumerating licensed lawyers and judges rather than, say, filtering get_agent results.

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