My sets

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 nothing beyond that: no statement about ordering, pagination limits, or what a returned set contains, and there is no output schema to fill the gap.

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?

It is short and front-loaded with zero waste, but that brevity is under-specification rather than economy. There is only one fragment, so there is no structure to assess beyond noting it reads like a label rather than a description.

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?

With no output schema and only read-only/open-world hints, the description carries most of the burden for a listing tool with pagination and a filter parameter—yet it explains neither the shape of results nor pagination behavior. An agent can guess its purpose from the name but not confirm it from the description.

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 page, count, and exclude_track_id are fully documented in the schema itself. The description contributes nothing about them, which is acceptable under the baseline but leaves no added value—particularly for exclude_track_id, whose filtering intent is already clear from 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?

The description is a noun phrase ('Sets (playlists) of the account.') that essentially restates the name 'list_my_sets' and title 'My sets' without a verb or scope statement. The one genuinely additive element is glossing 'sets' as playlists, but it does not distinguish this tool from siblings like get_set or add_to_set.

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 at all: nothing says when to call this versus get_set, list_groups, or the other listing tools. The agent must infer that this enumerates all of the authenticated account's sets, which the description never states outright.

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