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

The annotations already establish read-only, non-destructive, closed-world behavior. The description adds that it returns 'current text' and requires the page to be in the sitemap index, but it does not discuss auth, rate limits, caching, or other operational behavior.

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?

Three front-loaded sentences with no wasted wording. The purpose is stated first, followed by the prerequisite and then concrete use cases.

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 one-parameter read tool with full schema coverage and clear annotations, the description is nearly complete: it covers the domain, prerequisite, and content scope. It could still clarify return length or error behavior, but no output schema exists and the essential calling information is present.

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 coverage is 100%, and the schema already documents the url parameter in detail, including the get_site_map origin and site-relative path support. The description adds no further parameter semantics beyond the sitemap-index prerequisite, so the baseline 3 is appropriate.

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 resource ('current text of a PoolProFlorida.com page'), with a clear domain scope. It also gives the sitemap-index prerequisite, though it does not explicitly name get_site_map as the sibling that supplies valid URLs.

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?

Provides clear usage context: current published services, pricing, service areas, hours, policies, and page-specific business information. The prerequisite that the page must be in the current sitemap index is useful, but no explicit when-not-to-use guidance or named alternative is given in the description.

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