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

Annotations already declare readOnlyHint, idempotentHint, safe reads. The description adds genuinely new behavioral context: that provider-authored content is reported as data, separated from reviewer findings — useful for interpretation. But it doesn't disclose output shape, pagination, or what 'public evidence' entails beyond that.

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 tight sentence pair with no filler; the scope and the provider-vs-reviewer distinction are front-loaded and immediately actionable.

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 read-only inspection tool with a single param, the description covers what is returned at a high level and flags the authorship distinction. It still leaves the caller unsure about output format, size, and where serviceId comes from, which matters since there is no output schema.

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 0% and the single param serviceId has only a uuid format with no description. The description doesn't clarify serviceId's origin or meaning, only implying it identifies 'one currently available service'. With one parameter, baseline behavior is modest but an explanation of where serviceId comes from would have helped.

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 (read) and resource (evidence, review findings, limitations for a service), and adds a distinguishing detail that provider-authored context is separated from reviewer findings. Doesn't explicitly contrast with siblings check_availability and search_available_services, but the purpose is concrete and distinct.

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 phrase 'for one currently available service' implies a precondition (the service must be available), which hints at usage after search/availability checks. However, it never explicitly says when to use this versus the sibling tools or states prerequisites like needing a previously obtained serviceId.

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