get_drum_pads

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

No annotations are present, so the description carries the full burden. It specifies the returned fields (pad index, name, MIDI note, mute/solo state) but does not explicitly state that the operation is read-only, define 'visible', or describe error behavior.

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 compact and well-structured, with a one-line summary, a return clause, and a clean Args section. Every sentence adds value and there is no redundancy.

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 two-parameter getter with an output schema, the description covers the core usage: what it returns and how to target the device. It lacks failure-mode details and a precise definition of 'visible', but these are not critical for basic invocation.

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 description gives explicit semantic meaning to both parameters: 'Zero-based index of the track' and 'Zero-based index of the drum rack device'. This goes well beyond the schema's integer types and titles, making the invocation unambiguous.

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 action ('Get all visible drum pads') and the target resource ('a drum rack device'). This distinguishes it from sibling tools like set_drum_pad_mute/solo, which mutate pads, and get_drum_chains, which retrieves chains.

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 provides clear context: the tool is for retrieving visible drum pads from a drum rack device. It does not explicitly name alternative tools or list when-not-to-use scenarios, so it falls short of a 5.

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