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 context about what the profile includes, including the latest analysis job, but does not discuss freshness, permissions, errors, or response shape. With annotations carrying the main behavioral disclosure, this is adequate but not rich.

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 front-loaded sentence with no wasted words. It quickly establishes the read operation and the profile contents without burying the key 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 simple read operation, the description names the returned profile contents and annotations cover safety, which is helpful. However, it does not explain the required siteId/projectId parameters, and there is no output schema to fill that gap, leaving the definition only minimally complete for invocation.

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 description coverage is 0%, and the description does not explain the two required parameters, siteId and projectId. The phrase 'about a website' only vaguely hints at siteId and does not clarify projectId or the relationship between the two identifiers.

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 uses a specific verb ('Read') and resource ('site profile') and enumerates the profile contents: positioning, audience, products, competitors, and latest analysis job. This distinguishes it from sibling tools like list_sites, get_seo_health, or get_brand_mentions_overview by making clear it returns an integrated site profile rather than a list or a separate analysis.

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 states what the tool reads but gives no guidance on when to use it instead of alternatives such as list_sites, get_seo_health, or get_seo_diagnosis. There is no explicit when-to-use, when-not-to-use, or sibling routing guidance.

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