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

No annotations are provided, so the description must carry the full burden. It states 'Returns success or error' and describes the action, but does not disclose potential side effects (e.g., overwriting previous label, impact on mixer states). Behavior is not hidden but also not fully transparent.

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 (4 lines), front-loaded with the main purpose, and each sentence contributes without redundancy. It efficiently covers the action, parameters, and return behavior.

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 tool, the description covers the essentials: what it does, parameters, and return type. It could mention prerequisites (e.g., bus must exist) but overall is complete given the tool's simplicity. There is an output schema, but the description's mention of 'success or error' suffices.

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?

With 0% schema description coverage, the description adds significant meaning: it specifies the origin of 'bus_index' (from create_audio_bus) and gives examples for 'label'. This compensates for the lack of schema descriptions.

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 the tool sets the label of an audio bus, using a specific verb ('Set') and resource ('label of audio bus'). It distinguishes from siblings like 'set_bus_color' or 'set_bus_enabled' by focusing on the naming aspect.

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 when to use it (to rename a bus) but does not explicitly provide when-not-to-use or alternatives. It assumes the agent knows bus indices from a preceding call to 'create_audio_bus', which is helpful but not exhaustive.

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