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

Annotations already declare this as a read-only, idempotent, non-destructive, closed-world lookup, so the safety profile is covered. The description adds useful context by listing the covered rule topics and stating that results are not legal advice, but it does not disclose other behavioral traits such as rate limits, freshness, or citation behavior.

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 compact sentence followed by a short disclaimer, with the rule categories front-loaded. Every phrase contributes to scope or caveat, and there is no wasted text.

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 read-only lookup with an output schema and annotations covering safety, the description is largely complete: it states the domain, enumerates covered topics, and includes the legal disclaimer. It is only missing explicit parameter usage guidance and any note on result interpretation, which are minor here.

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 description does not mention the state, practice, or lang parameters at all. Schema coverage is only 67%, and while the two required parameters have schema descriptions, the description itself adds no meaning beyond what the schema already provides.

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 title and description together make clear that this tool returns lawyer advertising rules for a given state and practice, and the parenthetical enumerates the rule categories covered. It is not a generic verb-first statement, but the resource and scope are specific enough to distinguish it from the market-analysis siblings.

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 offers no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. The only usage-related note is the disclaimer that results are not legal advice, which is a caveat rather than selection guidance.

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