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

With no annotations provided, the description carries the burden of behavioral disclosure. It specifies that None leaves parameters unchanged, gives valid ranges for gain and subdivision, and explains the mapping for beat_subdivision. This exceeds what the schema alone provides, though it does not discuss side effects or scope.

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-line summary followed by a bulleted list of parameters with clear explanations. Every sentence adds value, and there is no filler.

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?

Given that an output schema exists (though not shown) and this is a straightforward setter, the description provides sufficient context: what the tool does, parameter meanings, and defaults. It does not mention global vs. project scope or potential side effects, but these are not critical for this tool's typical use.

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?

The input schema only provides types and null defaults, while the description adds essential semantics: gain range 0.0-1.0, default values, subdivision meanings, and the behavior of None for each parameter. This fully compensates for the 0% schema description coverage.

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 uses a specific verb 'Configure' with a clear resource 'metronome settings', and the parameter details reinforce what the tool does. It is distinct from sibling tools like set_bpm or set_time_signature because it specifically targets metronome click settings.

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 does not explicitly state when to use this tool versus alternatives or mention exclusions. The usage is implicitly clear from the purpose, but there is no explicit guidance on context or alternative tool selection, so it falls short of the higher bar.

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