set_random_play

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

Annotations declare readOnlyHint=false, consistent with a mutation operation. The description adds the behavioral trait of toggling (start/stop), but does not disclose details like what happens when already enabled, impact on current playback, or whether it overrides other play modes.

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 sentence with no redundant phrases. It is concise but could be expanded slightly for clarity without losing efficiency.

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 has two required parameters and no output schema, the description misses important context: it does not explain the meaning of the 'mode' enum, the effect of 'enabled', or what happens to current playback. It also does not differentiate from many similar play-control siblings.

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 coverage is 100% with brief descriptions for both parameters. The description does not add any semantic information beyond what the schema already provides, such as explaining how 'mode' affects the mix or the effect of 'enabled'.

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 uses specific verbs 'start' or 'stop' and identifies the resource as 'random play mix', clearly indicating the tool's function. It is distinguishable from sibling tools like 'play_track' or 'play_favorite' by focusing on random mixing, though it does not explicitly differentiate.

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 provides no guidance on when to use this tool versus alternatives such as 'play_track' or 'play_favorite'. No context about prerequisites or preferred scenarios is given.

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