get_device_parameters

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

The annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered without description help. The description adds only the shape of the returned data (name, value, min, max), which is largely redundant since an output schema exists; no mention of ordering, rate limits, or what happens when the device or track index is invalid.

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 lead sentence is front-loaded with purpose and return fields, and the bulleted parameter list is compact and scannable. The only waste is restating the parameter names, which is justified here by the empty schema descriptions.

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?

Safety and return shape are covered by annotations and the output schema respectively, and parameters are documented, so an agent could call this correctly. The missing piece is sibling disambiguation against get_device_params and the set_* variants, which is the most likely source of misfires for this 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?

With 0% schema description coverage, the description carries the full documentation burden and does so for all three parameters: it explains track_index as the track owning the device, device_index as a position in the device chain, and user_prompt as the originating prompt for telemetry. It could go further on index bounds or zero-vs-one-based indexing, but the essential meaning is conveyed.

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 states a specific verb and resource ('Read all parameters for a device on a track') and even names the returned fields (name, value, min, max), so an agent knows exactly what operation this performs. It does not, however, differentiate itself from near-identical siblings such as get_device_params, set_device_param, or expose_plugin_params, which an agent must disambiguate by name alone.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no mention of alternatives. Given that get_device_params sits right next to it in the sibling list, the absence of any routing statement is a meaningful gap; usage is only implied by the word 'Read'.

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