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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered by structured data. The description adds no behavioral context beyond that — no auth requirements, pagination, or freshness guarantees. The second sentence is contact metadata about the responsible lawyer, not behavior of the tool, so it does not raise this score.

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 first sentence is well front-loaded and compact. The second sentence is a full postal address for the responsible attorney, which is unlikely to help an agent select or invoke this tool and dilutes the description's signal.

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 zero-parameter, read-only catalog tool with no output schema, the description should at least characterize the return shape (a list of services with price and jurisdiction fields). It gestures at this via 'at what fixed price, under which laws,' but never states the structure of the response, leaving a modest gap.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description's 'at what fixed price, under which laws' hints at what the returned entries contain, which is a modest bonus but not parameter semantics.

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 states the resource clearly — the firm's service catalog with fixed prices and governing laws — and the title supplies the 'list' verb. It is distinguishable from sibling tools like get_engagement_terms or get_payment_link, which retrieve a single item rather than the whole offering. It lacks a crisp first-person verb (e.g., 'Lists all services...'), which keeps it out of 5 territory.

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 statement of when to call this versus the sibling getters, nor any prerequisite or exclusion. An agent must infer that this is a first-stop catalog lookup. No guidance is provided about whether it should precede open_matter or request_consultation.

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