mcp_opendaw_set_bus_label

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

No annotations exist, so the description carries full burden. It discloses the effect (set label) and return ('Returns success or error') but does not mention failure modes, overwriting behavior, or whether an invalid bus index produces an error. For a simple setter this is minimal but acceptable.

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?

Extremely concise: purpose statement first, then per-parameter clarifications, then return value. No unnecessary words or filler. Every sentence holds the needed information.

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 low-complexity setter with an output schema available, the description covers operation, parameter semantics, and return status. It doesn't discuss boundary conditions like invalid bus index, but the simplicity of the tool makes the description sufficiently complete.

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 has 0% description coverage, so the description compensates by explaining 'bus_index: Bus index from create_audio_bus' and 'label: New name for the bus' with concrete examples ('Reverb Bus', 'Drum Bus'). This adds useful meaning beyond the bare types in the 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?

Description opens with 'Set the label (name) of an audio bus' – a specific verb+resource+object. It clearly distinguishes from sibling tools like set_bus_color by targeting exactly the label/name operation.

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 explicit when-to-use/when-not-to-use or alternatives, but 'Bus index from create_audio_bus' implies a prerequisite, providing some usage context. The operation is self-evident for renaming a bus, but the tool doesn't state exclusions or compare with other bus-related setters.

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