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 that pricing is 'public' and lists returned facets, which is useful context, but it says nothing about rate limits, auth, or whether non-public listings are excluded.

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 front-loaded sentence with no filler; the resource is named first and the returned fields follow. It is slightly list-like but every element 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 not be spelled out, and annotations cover safety. What remains missing is the usage context (how to get a URL, relationship to firstdibs_search), leaving the definition adequate but incomplete for a detail-fetch tool.

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 0% and the description never mentions the single url parameter, so it adds no syntax or format detail. However, with only one obvious required parameter, the gap is minor rather than crippling.

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 resource (1stDibs product detail) and enumerates the fields it returns (pricing, availability, brand, category, description, images). It is distinguishable from the sibling search/categories/designers tools by being the detail endpoint, though it never names those alternatives explicitly.

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 firstdibs_search, nor on how a product URL is obtained. An agent must infer that a detail call follows a search, and nothing indicates prerequisites or the expected input form.

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