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

No annotations are present, so the description carries the full burden of behavioral disclosure. It discloses nothing: no side effects, no network behavior, no authentication requirements, no output format, and no edge cases. The description is completely uninformative about how the tool behaves.

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 extremely short, but this is under-specification rather than effective conciseness. There is no front-loaded actionable information, only a redundant restatement of the name.

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, no annotations, and a meaningless description, an agent has essentially no information needed to call this tool correctly or interpret its result. This is completely inadequate for a tool that presumably takes URLs and a base and produces a sitemap.

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 100%, so the baseline is 3 even though the tool description adds no parameter information. However, the schema descriptions ('Base to process', 'Urls to process') are themselves very vague and do not clarify formats, constraints, or how the two parameters relate.

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 'Sitemap Gen: Sitemap Gen' is a pure tautology that restates the tool name without any verb, resource, or action. An agent cannot determine what this tool actually does, what input it expects in practice, or what output it produces.

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?

There is no guidance on when to use this tool versus alternatives. The sibling list includes x402-sitemap-parse and many other tools, but the description gives no context for when sitemap generation is appropriate or how it differs from related operations.

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