hs4.devices.list

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only mentions filtering capabilities but fails to state that this is a read-only operation, describe pagination behavior (despite limit/offset parameters in schema), or indicate whether results are comprehensive. The description is insufficient for an agent to understand side effects or safety.

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, well-structured sentence that front-loads the verb and resource, then specifies the key filters. It is concise with no wasted words. However, it could benefit from a brief mention of pagination parameters to improve structure without losing 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 9 parameters, no output schema, and no annotations, the description is far from complete. It omits return value details, pagination mechanics, and parameter constraints (e.g., limit defaults, maxDevices range). An agent would lack essential context to fully utilize the 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?

Schema description coverage is 0%, so the description must compensate. It adds meaning for three parameters (location1/location2, interfaceName, capability) but ignores six others: limit, offset, includeRaw, maxDevices, includeControls. Without these semantics, an agent cannot correctly use parameters like pagination or raw data inclusion. The coverage is partial and leaves critical gaps.

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 clearly states the action ('List'), the resource ('HS4 devices'), and specifies three filter dimensions (location, interface, capability). This provides a clear purpose and distinguishes it from general listing. However, it could be more explicit about how it differs from sibling tools like hs4.devices.get or hs4.resolve.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?

No guidance on when to use this tool versus alternatives such as hs4.devices.get (likely fetching a single device) or hs4.resolve.devices. The description does not list any prerequisites or exclusions, leaving the agent to infer appropriate usage.

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