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 the useful scope constraint that results relate to handbag listings, but says nothing about pagination, result volume, or whether the output is exhaustive; with annotations carrying the safety burden this sits at a minimum-viable 3.

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 or repetition. It is tight and readable, though the brevity edges toward under-specification rather than true economy.

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 described, but the remaining gaps are substantial: no usage guidance and an unexplained parameter at 0% coverage. For a discovery tool in a cluster of sibling designer tools, the description does not supply enough to route or invoke it confidently.

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?

There is a single 'category' parameter with 0% schema description coverage, so the description carries the full burden of explaining it. Instead it only loosely gestures at 'handbag listings' and never clarifies what values the category accepts or how it narrows the designer list.

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 (designers) and scope (handbag listings) on 1stDibs, so the agent knows this is designer discovery rather than a product or category lookup. It does not explicitly distinguish itself from the sibling firstdibs_search or firstdibs_categories, so sibling differentiation is left to inference.

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 when-to-use guidance, no mention of alternatives (e.g., firstdibs_search or firstdibs_categories), and no prerequisites. The only hint is the 'handbag listings' scope, which implies a domain but not a routing decision.

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