channel_set_pan

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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It states the mutation ('Set channel pan') but does not mention clamping behavior, persistence, side effects, whether the channel must be selected, or what happens on invalid input. This is a significant gap for a write operation with no annotation support.

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 terse sentence that front-loads the verb and resource without any fluff. The range is included efficiently, though the overall terseness contributes to the information gaps penalized in other dimensions.

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 two-parameter mutation tool with no annotations and no output schema, this description is too minimal. It does not define the index parameter semantics or clarify how this interacts with related concepts like mixer panning, leaving an agent to guess critical invocation details.

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 for parameters. It adds meaning to 'pan' by giving the range (-1.0..1.0), but it leaves 'index' completely unexplained, including whether it is zero-based and which channel namespace it refers to.

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 a specific verb and resource ('Set channel pan') and even includes the valid range (-1.0..1.0), making the core purpose clear. It does not explicitly distinguish itself from sibling tools like mixer_set_pan or channel_set_volume, but the resource and operation are unambiguous enough.

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?

No guidance is provided on when to use this tool versus alternatives such as mixer_set_pan or automation_record_channel_pan. The intended use is only implied by the name and description, with no exclusions or conditions stated.

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