get--v3-domain-aggregates-devices

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

No annotations are provided, so the description carries full burden. It implies a read operation ('aggregate counts') but doesn't disclose behavioral traits like whether it's safe, what permissions are needed, rate limits, or response format. The description adds minimal context beyond the basic 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 a single, efficient sentence with no wasted words. It's appropriately sized and front-loaded, making it easy to parse quickly.

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 1 parameter with 0% schema coverage, no annotations, no output schema, and many sibling tools, the description is incomplete. It doesn't explain the tool's scope, parameter usage, or behavioral context, leaving significant gaps for a tool that aggregates data.

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 description coverage is 0% with 1 parameter ('domain'), and the description provides no information about this parameter. It doesn't explain what 'domain' means, its format, or how it affects aggregation. The description fails to compensate for the lack of schema documentation.

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 'Aggregate counts by devices triggering events' states the purpose (aggregating counts) and resource (devices/events), but is vague about what 'events' refers to and doesn't distinguish from sibling tools like 'get--v3-domains-domain-tag-devices' which appears similar. It provides basic verb+resource but lacks specificity.

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?

No guidance on when to use this tool versus alternatives is provided. The description doesn't mention prerequisites, context, or exclusions. With many sibling tools in the same domain, this omission leaves the agent without direction on tool selection.

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