hs4.devices.controls.get

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

With no annotations, the description carries full burden for behavioral disclosure. It states 'Retrieve' implying a read-only, idempotent operation, but does not confirm no side effects, mention authentication needs, rate limits, or other behavioral traits.

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 concise sentence that conveys the core purpose. It is front-loaded and non-redundant, but could benefit from slightly more detail while remaining concise.

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 lack of annotations, output schema, and minimal description, the contextual completeness is low. An agent may not understand what 'control pair metadata' entails, or how to interpret the results.

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 description clarifies that the 'refs' parameter refers to device references and that the tool returns metadata. However, with 0% schema description coverage, it does not explain the format or constraints of the refs array beyond the schema, leaving ambiguity about what constitutes a valid ref.

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 identifies the action as retrieving control pair metadata for device refs. It distinguishes from sibling tools like hs4.devices.get and hs4.devices.status.get by specifying 'control pair metadata', making the purpose clear.

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 is provided on when to use this tool versus alternatives such as hs4.devices.get or hs4.devices.status.get. The description lacks any mention of context, prerequisites, or exclusions.

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