fashionphile_sitemaps

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

With no annotations, the description carries the burden and it does add useful context: it identifies the upstream source (/sitemap.xml), the output nature (child sitemap URLs), and the fact that the storefront URL is fixed server-side. However, it does not disclose output format, pagination, rate limits, or any caching/error behavior, leaving some behavioral ambiguity.

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 two sentences with no filler. It front-loads the primary purpose, then gives the operational detail about the source URL and the fixed storefront, making it easy for an agent to parse quickly.

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 zero-parameter, low-complexity listing tool, the description is mostly complete: it names the source index, the output content, and the fixed configuration. The main gap is the lack of a defined output shape or any relationship/contrast with the similarly named fashionphile_sitemap_urls sibling, but this is not critical for a basic 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?

The tool has zero parameters, which is the baseline-4 case. The description goes slightly beyond the empty schema by explaining that the storefront URL is fixed server-side, which justifies why no input is required. It does not explicitly say 'no parameters needed', but the implication is clear.

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 clearly states the action ('List Fashionphile sitemaps') and the specific resource, and it explains that the tool returns child sitemap URLs from Fashionphile's /sitemap.xml index. It does not explicitly contrast itself with the similarly named sibling fashionphile_sitemap_urls, so it stops short of full sibling differentiation.

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 provides no when-to-use guidance, no exclusions, and no mention of alternatives. An agent cannot tell from this description when to choose fashionphile_sitemaps over the very similar-looking fashionphile_sitemap_urls or other sitemap-related tools.

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