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 genuinely useful context beyond that: the source is a credential-free endpoint (no auth needed) and results are 'normalized', telling the agent the data shape is standardized rather than raw.

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 tight sentence that front-loads the operation and ends with the concrete data source. No filler, though it is terse enough that nothing about usage or edge cases is stated.

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-value explanation is unnecessary, and annotations cover the read-only profile. The one-sentence description plus schema gives an agent enough to call this correctly; only usage routing to everlane_pages is missing.

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%, so the single 'handle' parameter and its slug semantics are already documented in the schema. The description reinforces that handle maps to a URL path segment ({handle}.json), which adds marginal value but not syntax or format detail beyond the schema.

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 ('Returns'), resource ('static page detail'), and scope (the /pages/{handle}.json endpoint), which implicitly separates it from the sibling everlane_pages list tool. Clear enough for an agent to distinguish single-page detail retrieval from a pages listing without opening the schema.

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?

No when-to-use guidance, no prerequisites, and no explicit routing to alternatives such as everlane_pages. The agent must infer from the name and 'detail' wording that this is the per-handle lookup path rather than the list path.

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