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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful framing (normalized records, fixed public storefront, pagination model) but discloses nothing about auth needs, result ordering, or rate limits, matching the calibrated 'adds some value but not rich behavioral context' level.

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?

Two sentences, zero filler, with the purpose front-loaded and the sibling routing confined to a second sentence. Every clause earns its place.

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?

An output schema exists, so return values need no explanation, and annotations carry the safety profile. Combined with full parameter coverage and the alternative-tool routing, the definition is complete for correct invocation, with only marginal behavioral detail (ordering, edge pagination) left unstated.

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 both parameters are already fully documented in the schema. The description only references `page` and `limit` as a pagination pair without adding format, default, or boundary detail beyond what the schema provides, so the baseline 3 applies.

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 states a specific verb (List) and resource (normalized static-page records) drawn from a named source (Everlane's fixed public storefront). An agent can distinguish this browse-all tool from the single-record everlane_page, though the differentiation is delivered in the second sentence rather than baked into the purpose statement itself.

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?

It explicitly names two sibling alternatives and the condition that selects each (everlane_page for one page, everlane_sitemaps to discover sitemap URLs), which is clear routing context. It stops short of stating affirmatively when this list tool is the right choice versus those, so it is strong but not a complete when/when-not statement.

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