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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description goes beyond that by naming the concrete data returned (download status, errors/warnings, submission vs. index counts), which is valuable given there is no output schema.

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 that delivers purpose and return content with zero filler. Nothing to trim.

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?

With no output schema, the description usefully summarizes the return payload, but it leaves the siteUrl parameter's role unexplained and gives no pagination or error-handling context. Adequate but with a clear parameter gap.

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 only 50%: feedpath is documented in the schema, but siteUrl has no description anywhere. The description mentions no parameters at all, so it does not compensate for the undocumented optional siteUrl (e.g., when it is required vs. defaulted).

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 (get) and resource (sitemap) plus the scope 'one specific sitemap,' which distinguishes it from the sibling list_sitemaps. It also enumerates exactly what status is returned: last downloaded, errors/warnings, URLs submitted vs. indexed.

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 'one specific sitemap' implies this is the single-sitemap counterpart to list_sitemaps, but no explicit when-to-use guidance or named alternative is given. Usage is only inferable.

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