set_mixer_channel_name

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only gives the action and parameter hints ('0=Master'), but does not mention whether the channel must already exist, whether the change is reversible, how errors are handled, or what side effects may occur.

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 extremely concise, front-loaded with the action, and uses a clear argument list. Every line serves a purpose, and there is no filler or repetition of schema details.

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 two-parameter setter with an output schema, so the description is minimally viable. However, it lacks important context such as whether the channel must exist, what happens for invalid channel numbers, and whether renaming affects other references. These gaps are notable for a mutation without annotations.

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 0%, so the description must compensate. It adds meaningful semantics for both parameters: channel_num is clarified as 0=Master, and name is described as 'New channel name'. This goes beyond the bare schema, though the explanation of 'name' is somewhat tautological.

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 states a specific verb ('Rename') and resource ('mixer channel'), which clearly conveys the tool's function. It does not explicitly differentiate from sibling tools like set_mixer_channel_volume, but the action and target are distinct enough for an agent to understand the core purpose.

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 add_mixer_channel or get_mixer_channels. It implies usage when renaming is desired, but there is no explicit context, prerequisite, or exclusion.

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