create_player_playback_mute

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

The description only restates the mute action and the endpoint; it adds no behavioral context beyond the annotations. It does not contradict the annotations, but it also does not disclose the effect on current playback or the relationship to unmuting.

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 very short and contains no filler; the endpoint line is a useful concrete reference. It is concise, though the label-like phrasing prevents a perfect score.

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?

This is a simple zero-parameter action with an output schema and annotations, so the description does not need to be lengthy. However, a more explicit statement of what muting does and a pointer to the unmute counterpart would make it complete for an agent deciding whether to call it.

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 has zero parameters and schema coverage is 100%, so there is no parameter detail for the description to add. The baseline of 4 for a parameterless tool applies.

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 mostly a label—'Player Mute.'—that restates the tool name, with the HTTP endpoint as additional context. It identifies the resource (player playback) and the action (mute), and can be differentiated from create_player_playback_unmute by direction, but it lacks an explicit sentence stating what the operation does.

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 on when to use this tool versus alternatives such as create_player_playback_unmute or create_player_playback_set_parameters. No conditions, prerequisites, or explicit references to sibling tools are provided.

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