get--v3-domains-domain-tag-devices

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The phrase 'List of supported devices' suggests a read-only operation, but it doesn't clarify whether this is a safe query, what permissions might be required, whether results are paginated, what format the output takes, or any error conditions. For a tool with no annotation coverage, this description provides essentially zero behavioral context beyond the minimal implication of a read operation.

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 extremely concise at just three words, which could be appropriate if it were more informative. However, this brevity comes at the cost of being under-specified rather than efficiently informative. While it's not verbose or poorly structured, it fails to provide the necessary context that would justify such extreme conciseness.

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?

Given the tool's apparent complexity (involving domains, tags, and devices), the complete lack of annotations, 0% schema description coverage, no output schema, and the presence of many similar sibling tools, this description is completely inadequate. It provides almost no useful information about what the tool does, how to use it, what to expect, or when to choose it over alternatives. The agent would be operating almost entirely in the dark.

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 input schema has one required parameter 'domain' with 0% description coverage in the schema itself. The tool description provides no information about this parameter - what it represents, what format it expects, what values are valid, or how it affects the results. The description doesn't even mention that a domain parameter is required. With low schema coverage and no parameter information in the description, this creates significant ambiguity about how to use the tool correctly.

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 'List of supported devices' is a tautology that essentially restates the tool name 'get--v3-domains-domain-tag-devices'. It doesn't specify what action is performed (list? retrieve? filter?), what resource is being accessed (devices for a domain? devices with a tag?), or how it differs from sibling tools like 'get--v3-domain-aggregates-devices'. The description provides minimal value beyond the name itself.

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 absolutely no guidance about when to use this tool versus alternatives. There are multiple sibling tools that appear related to domains, tags, and devices (e.g., 'get--v3-domain-aggregates-devices', 'get--v3-domains-domain-tag-countries'), but the description offers no context about how this tool differs from them or what specific use case it addresses. The agent would have no basis for choosing this tool over similar-looking alternatives.

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