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

Annotations declare readOnly=false and destructive=false, and the description aligns by describing control operations with immediate effects (e.g., 'set_volume', 'mute'). It adds the return format and examples, going beyond annotations. It doesn't detail side effects of operations like 'handover' or 'select_stream', but given the annotations and operation names, the transparency is adequate.

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 well-structured and front-loaded with the main purpose, followed by the rationale, return format, and examples. Every section earns its place—the rationale explains the consolidation, the return format is essential given no output schema, and the examples are practical. It is concise without unnecessary fluff.

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 tool with 7 operations, 6 parameters, and no output schema, the description provides the return format and examples, covering essential invocation details. However, operation-specific behaviors (e.g., what 'handover' does) are not explicitly described beyond the enum and parameter names. Still, the schema covers parameter meanings, and the examples illuminate common operations, making it reasonably complete.

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%, so the baseline is 3. The description adds value by providing examples that map specific parameters to operations (e.g., operation='list_streams' with media_key; operation='set_volume' with client_id and volume). These examples help the agent understand parameter-operation relationships beyond the schema's field descriptions.

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 identifies the tool as audio management operations for Plex Media Server, mentioning 'audio-focused control operations' and 'real-time playback adjustments.' It differentiates reasonably from siblings like plex_streaming or plex_quality through its focus on control operations, though it doesn't explicitly name those alternatives.

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 portmanteau rationale explicitly states the consolidation for minimizing latency during real-time playback adjustments and stream switching, giving a clear usage context. It does not explicitly state when not to use it or name alternative tools, but the 'real-time' context strongly implies its targeted use case.

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