set_send_volume

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

Beyond the destructiveHint=false annotation, the description adds no behavioral context. It doesn't mention whether the send must already exist, whether the change is reversible/undoable, or what happens when volume_db is out of range. There is no contradiction with the annotation, but the mutation behavior is under-disclosed.

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 compact and front-loaded with the core action, followed by a clean parameter list. Every sentence serves a purpose with no filler, though the parameter list is incomplete.

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?

With no output schema and only a destructiveHint annotation, the description carries the burden of explaining how to call the tool. It fails to document send_index, a required parameter, and gives no behavioral context, so an agent cannot fully determine correct usage from the description alone.

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?

The Args section adds useful semantics for two of three required parameters: track_index is 0-based and volume_db is in dB. However, send_index is required by the schema and is completely undocumented, which is a meaningful gap given the schema itself provides no descriptions (0% coverage).

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 opening sentence names a specific verb and resource ('Set the volume of a track send'), which distinguishes it from sibling send-related tools like set_send_dest_channels and set_send_source_channels. The resource is precise enough that an agent can identify the intent immediately.

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 when-to-use or alternative-selection guidance is provided. The description states what the tool does but never mentions when it should be preferred over other send-editing tools or any prerequisites such as the send needing to already exist.

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