mixer_set_send_level

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

There are no annotations, so the description must carry the full behavioral burden. It discloses the operation and the 0..1 range, but it does not state whether the tool creates the send connection or merely adjusts an existing one, how invalid track indices are handled, or whether out-of-range values are clamped. This ambiguity matters for a mutating tool.

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?

A single sentence contains the action, subject, source, destination, and value range with no redundant or filler words. The most decision-relevant information is front-loaded.

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 three required parameters and no output schema, the description covers the core call semantics. However, it omits usage prerequisites and the relationship to mixer_route, which an agent likely needs to know to invoke it correctly in a mixing workflow.

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 adds critical meaning: 'from one mixer track to another' maps src_track and dst_track, and '(0..1)' defines level's valid range. However, it does not explain track indexing conventions, whether the tracks are zero-based, or how non-numeric or out-of-range level values are treated.

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 a specific verb and resource: set the send level, and it clarifies the directional relationship ('from one mixer track to another') plus the valid range (0..1). It is distinct from sibling tools like mixer_route or mixer_set_volume because 'send level' is a different parameter, though it does not explicitly name those alternatives.

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 given about when to use this tool versus mixer_route, mixer_set_volume, or other mixer controls. The description does not mention prerequisites such as an existing send/routing, whether the send must first be created, or what happens when the source and destination tracks are invalid or the same.

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