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

Annotations already declare readOnly, idempotent, openWorld=false and non-destructive, so the safety profile is covered. The description adds the return surface (name, profile URL, category, optional metadata) which matters because there is no output schema, and it signals that metadata fields are inconsistent/optional ("any available"). It says nothing about pagination or total counts, which keeps it off a 5.

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?

Two sentences, zero padding, and the scoping constraint is front-loaded before the return-value sentence. Every clause carries information.

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 one-parameter read tool with no output schema, the description does the important work of describing the returned fields. It is only slightly incomplete in not indicating whether results are truncated or how the default cap of 50 interacts with a broader collection.

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?

With a single parameter at 100% schema description coverage, the schema already documents limit and its default of 50. The description adds no meaning beyond that, so the baseline 3 applies.

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 and resource ("List solo service-provider profiles") and then pins down the scope with a defining constraint — businesses without a fixed physical location — plus concrete examples. This lets an agent distinguish it from the place-oriented siblings (search_places, get_place) without opening any schema.

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 qualifying definition of the resource implicitly tells the agent what belongs in this list, which is a real selection signal. However, it never states when to reach for this versus a sibling like search_places or list_categories, and imposes no explicit exclusions or prerequisites.

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