set_shuffle

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

With no annotations, the description bears the burden of explaining behavior. It correctly states the primary action (enabling or disabling shuffle) but does not mention any side effects (e.g., whether playback restarts, whether the setting persists, or how it interacts with the current queue). This is partially transparent but not fully detailed.

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, efficient sentence that communicates the tool's purpose without any redundant or extraneous information. It is well-structured and directly to the point.

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?

Given the tool's simplicity and the presence of an output schema (presumably a void or confirmation response), the description is adequate for understanding the core action. However, it omits any mention of errors, edge cases (e.g., invalid player), or the exact nature of the 'current play queue', which prevents it from being fully complete in broader contexts.

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?

The input schema lists two required parameters ('player' and 'enabled') with no descriptions, and the tool description adds no explanation of their meaning or expected formats. For instance, it does not clarify whether 'player' is an ID, name, or resource identifier, nor what values 'enabled' accepts beyond boolean. This leaves the agent to guess parameter semantics.

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 clearly states that the tool toggles shuffle on or off for the current play queue, using the explicit verb 'turn' and identifying the resource. It is unambiguous and concise, leaving little room for misinterpretation.

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?

The description does not provide any guidance on when to use this tool versus alternatives among the sibling tools (e.g., play, pause, skip). It only states what the tool does, without contextual cues or conditions for selection.

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