get_config_group_device_variables

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

With no annotations, the description carries the full behavioral burden. 'Get' implies a read, but the description says nothing about whether values reflect inherited or overridden variables, whether resolution requires the device to be attached to the group, or what the response contains. For a no-annotation tool this is a meaningful gap.

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?

A single sentence with the scope qualifier front-loaded in parentheses; no filler, no repetition of the tool name or title.

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?

The tool is simple (2 params, 1 required), but with no annotations and no output schema, the description should say more about what the returned variable set looks like and how inheritance or overrides are represented. It is minimally sufficient to call correctly but not to interpret results confidently.

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?

Schema coverage is 100%, so both parameters are already documented in detail, including the accepted device identifier formats. The description adds one piece of meaning the schema omits — that omitting device returns values for all devices — but contributes nothing further about the config_group identifier or value semantics.

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 ('Get device-specific variable values of a configuration group') and scopes it with '(all devices, or one device).' It clearly distinguishes variable values from plain group metadata, though it never names the near siblings get_config_group or preview_config_group_device_config to clarify the boundary.

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 parenthetical '(all devices, or one device)' implies when to supply the device argument versus omitting it, which is useful. However, there is no explicit guidance on when to use this tool rather than get_config_group or preview_config_group_device_config, and no prerequisites are stated.

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