set_chain_device_parameter

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

With no annotations provided, the description carries the full burden. It discloses two important behaviors: parameter name resolution is scoped to the device, and the value is clamped to the parameter's range. These go beyond the basic mutation implication, providing useful operational context.

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: an opening sentence stating purpose, a short note on scoping, and a bullet-like parameter list. Every sentence earns its place with no redundancy or fluff.

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 setter tool with six parameters, no output schema, and no annotations, the description covers the essential behavioral and parameter details. It explains the scoping constraint and clamping, but could be slightly more complete by mentioning index base (e.g., 0-based) or error behavior if the device/parameter is not found.

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 lists and explains all six parameters, clarifying what each index refers to (e.g., 'index of the rack on the track', 'index of the chain inside the rack'). Since schema description coverage is 0%, this textual explanation is essential and mostly complete, though it does not specify zero-based vs one-based indexing.

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's purpose: 'Set a parameter on a device nested inside a rack chain' and gives a specific example ('a drum pad's decay'). This distinguishes it from sibling tools like set_device_parameter or set_master_device_parameter, which target different locations.

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 clarifies when to use this tool by specifying the target: a device nested inside a rack chain. It also warns that parameter name resolution is scoped to that one device, preventing accidental matches elsewhere. However, it doesn't explicitly name alternatives like set_device_parameter for non-rack devices, so it stops short of full exclusion guidance.

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