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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful content context by naming what the settings contain (DR range, page types), but says nothing about scope, required access, or what happens when no discovery has been configured.

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?

A single front-loaded sentence with no filler or repetition. It is efficient, though the terseness comes partly from omitting information that would be useful.

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?

There is no output schema, so the description must carry return-value explanation; it partially does by naming the two settings returned. However, with two undocumented required parameters and no routing to siblings, it is only minimally adequate for a scoped getter.

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?

Both required parameters (projectId, siteId) have 0% schema description coverage, and the description never mentions them. It also does not clarify the relationship between project and site scoping, so an agent must guess how the two identifiers interact.

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 a concrete resource, going so far as to name the returned fields (Domain Rating range, page types). It distinguishes itself from the write sibling update_prospect_discovery_settings implicitly through "Read," but never names that sibling or get_prospect_discovery, so differentiation is left to inference.

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?

No when-to-use guidance and no alternatives named. With sibling tools like update_prospect_discovery_settings, get_prospect_discovery, and start_prospect_discovery in the same family, the description should route the agent but instead provides none of that context.

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