Set Channel Send to Bus

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

Annotations already indicate idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds context that this controls the amount of channel signal sent to the bus, which is essentially what the tool does. It does not disclose additional behavioral traits such as overwrite semantics or effects on existing settings, but given the strong annotations, this 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 two sentences, front-loaded with the main action, and every word contributes. It is concise and structured effectively.

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 simple setter with full schema coverage and informative annotations, the description is complete enough. It clearly defines what a send level is, which is helpful context. No output schema is needed, and the tool's behavior is straightforward. Slight deduction for not mentioning that values overwrite existing sends, but this is implied by 'Set'.

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%, with each parameter having a clear description and the unit enum including defaults. The description repeats the linear/dB ranges already in the schema, adding no new meaning beyond what the structured schema provides. Baseline 3 is appropriate.

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 states the verb 'Set', the resource 'send level from a channel to a mix bus', and the purpose 'controls how much of the channel signal is sent to the bus'. This distinguishes it from sibling tools like 'bus_set_volume' or 'channel_set_volume'.

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 implies use when adjusting send levels to a bus, but does not explicitly state when to use this tool versus alternatives or when not to use it. The context is clear but lacks explicit exclusions or alternative tool references.

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