create_player_playback_unmute

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

Annotations already indicate readOnlyHint=false, idempotentHint=true, and destructiveHint=false, but the description adds no behavioral context beyond the name. It doesn't mention that this unmutes playback, what state changes occur, or any side effects. No contradiction exists, but nothing is disclosed beyond what the name already implies.

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 does not waste words on fluff. However, 'Player Unmute.' is entirely redundant with the tool name)Skip and the endpoint line, while useful, is the only substantive piece. It is concise to the point of under-specification, but not overly verbose.

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?

For a zero-parameter tool with an output schema and safety annotations, the description is technically minimally viable – an agent can infer it unmutes player playback. However, it lacks any context about when to use it, how it relates to other playback commands, or what 'player' refers to. In a large sibling set, this is a gap.

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 tool has 0 parameters and the schema coverage is 100% trivially, so there is nothing to add. The description is not required to compensate for missing parameter docs, and the baseline of 4 for zero-parameter tools 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 'Player Unmute.' which simply restates the tool's name in human-readable form. It lacks a verb and doesn't explain what action is performed or on what resource beyond the name. The HTTP endpoint is provided but adds no semantic meaning. It does not distinguish this tool from the many other playback control siblings.

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 gives no guidance on when to use this tool versus alternatives such as create_player_playback_mute or create_player_playback_set_state. There are no prerequisites, context, or exclusions provided. An agent gets no help deciding between this and sibling tools.

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