List product sets

reddit_ads_list_product_sets
Read-only

List product sets for a Reddit Ads catalog to inspect or manage catalog groupings. Provide the catalog ID to retrieve product set details, with optional pagination.

Instructions

List product sets of a catalog.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

C2.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds nothing beyond that — no note on pagination behavior (which defaults to one page via max_pages), result volume, or whether an empty catalog returns an empty set.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single short sentence, front-loaded with the verb and resource. Nothing is wasted, though it is arguably under-specified rather than deliberately concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only list tool with no output schema, the definition is minimally adequate but omits how results relate to pagination and to sibling product-set tools. An agent can call it correctly given the schema, but gains no operational context from the description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 75% and the pagination parameters (max_pages, page_size, page_token) are well documented in the schema itself. The description adds no meaning to catalog_id, but the baseline of 3 applies since the schema carries most of the parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (List) and resource (product sets) scoped to a catalog, so the agent knows what it retrieves. It does not distinguish itself from the sibling list_product_set_products or get_product_set, which could cause confusion about which list tool to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no indication of when to use this versus get_product_set, list_product_set_products, or list_catalogs. The agent must infer usage purely from the name and required catalog_id.

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