Get playlist reposters

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

Annotations already declare the tool as readOnly, idempotent, and non-destructive. The description adds no additional behavioral context beyond the basic list operation, such as pagination behavior, ordering, authentication needs, or result shape. It does not contradict the annotations but contributes little beyond them.

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?

The description is a single, front-loaded, and unambiguous sentence with zero filler. Every word contributes to communicating the action and resource.

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?

The tool is invokable because the schema documents the required parameters and annotations establish safety. However, the description lacks usage context such as pagination continuation, result ordering, or when to prefer this over listing a playlist's tracks, leaving the definition at a minimum-viable level.

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%: 'playlist' documents accepted formats and 'limit' documents range and default. The description adds no parameter-level meaning, so the baseline of 3 is appropriate because the schema already does the heavy lifting.

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 states a specific action ('List') and a precise target resource ('users who reposted a playlist'). This clearly differentiates it from sibling tools like soundcloud_get_playlist or soundcloud_get_playlist_tracks, with no ambiguity about the operation.

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 about when to use this tool versus alternatives, no mention of prerequisites, and no reference to related tools such as soundcloud_set_repost or soundcloud_get_playlist_tracks. The agent must infer the intended use case entirely from the tool name.

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