get_mixer

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

With no annotations, the description carries the full burden. It discloses that each value is reported in three formats (raw 0..1, dB, and Live's display string), which is useful behavioral context. It also notes that track_index is ignored for 'master', showing edge-case behavior. It does not mention error handling or side-effect safety, but the getter nature is clear from the name and description.

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 concise and well-structured: a one-sentence purpose, a one-sentence return-format explanation, and a clear parameter list. No filler or redundancy; every sentence adds value.

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?

The tool has no output schema, so the description should explain return values. It explains each value is reported three ways, but does not specify the exact JSON structure (e.g., object shape or key names), potential error cases, or how many sends are included. Despite these gaps, the description provides enough for a simple getter with two optional params, so it's slightly above adequate.

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. It does so thoroughly: track_type is explained with its allowed values and default, and track_index is described with its behavior (ignored for master). This gives the agent full understanding of parameter meanings and special cases beyond the raw schema.

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 'Get the mixer state (volume, panning and sends) for a track' – a specific verb and resource. It distinguishes itself from sibling tools like set_track_volume or set_track_panning by being the read/get variant, and from get_track_info by focusing on mixer state.

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 usage as a read-only getter for mixer values, but does not explicitly state when to use this tool vs alternatives, nor does it mention exclusions (e.g., 'not for setting values'). The parameter explanations give practical context, but no direct comparison to sibling getters/setters is provided.

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