set_chain_device_parameter

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

Adds that values clamp to the parameter's native range, providing behavioral insight beyond annotations. However, does not disclose other behaviors like permission requirements or undo 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?

Two sentences, no redundancy. First sentence states action and context, second adds clamping behavior. Front-loaded and efficient.

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?

References get_rack_chains for indices and mentions clamping, but lacks information on error handling, prerequisites, or how to obtain the indices. Output schema exists but description could be more complete for a 6-parameter tool.

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?

Does not explain any parameters beyond the generic context. with 0% schema description coverage, the description should provide details on parameter formats, valid ranges, or how to specify the parameter, but it does not.

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 clearly states it sets a parameter on a device inside a rack chain, specifying the source of indices (get_rack_chains). This distinguishes it from sibling tools like set_device_parameter which operate on non-chain devices.

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?

Implies usage context by referencing get_rack_chains for indices, but does not explicitly state when to use this tool versus alternatives or when not to use it.

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