send

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

With no annotations, the description carries the full burden, and it does clarify that track_index is the source (-1 master) and dest_index is the destination track. However, it is silent on return values, side effects, and action-specific behavior such as which parameters are required for delete versus update.

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-loads the action variants and the two key index parameters. The opening 'Track sends' is somewhat ambiguous, but the structure wastes little space and is easy to scan.

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 7-parameter tool with no annotations and no output schema, this description is incomplete. An agent lacks essential context about action-specific parameter requirements, what send_index refers to, and what result is returned by list/add/delete/update.

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, but it only explains track_index and dest_index. Critical parameters like send_index, pan, mute, and volume_db are left to name inference, and send_index is especially important for identifying which send to delete or update.

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 identifies the resource (sends) and enumerates the supported operations via the action field, so an agent can see this tool manages sends on tracks. It does not use an explicit verb+object phrasing like 'manage audio sends,' but the action enum resolves most ambiguity. It does not explicitly differentiate from sibling tools, but the resource is distinct 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 when-to-use guidance or alternative tool comparisons are provided. The description implies the tool is for send routing, but it does not state when to prefer this over track, fx, or other siblings, nor does it explain prerequisites for add/update/delete.

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