skylight_list_devices

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

The readOnlyHint annotation already establishes this as a safe read operation, and the description does not contradict it. It adds the scoping detail that devices are attached to a Skylight frame, but it does not disclose behavior when frameId is omitted, pagination, ordering, or access requirements.

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 front-loaded sentence with no filler, wasted words, or redundancy. It delivers the core operation and resource efficiently.

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?

With one optional parameter and 0% schema coverage, the description should explain whether frameId is required and what happens without it, but it does not. There is also no hint of the returned data shape, leaving meaningful gaps for reliable invocation.

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%, and the description never mentions frameId or its optionality/effect on results. The phrase 'attached to a Skylight frame' weakly aligns with frameId but adds no concrete parameter semantics beyond what the property name already implies.

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 uses a specific verb ('List') and a clear resource ('physical devices attached to a Skylight frame'), making the tool's purpose immediately distinguishable from sibling list tools such as skylight_list_frames and skylight_list_frame_members. It describes scope rather than merely restating the name.

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?

There is no when-to-use guidance, no mention of prerequisites, and no explicit alternative or exclusion relative to sibling tools. The only implied usage is 'when you want to list devices,' which is not enough to choose between this and related frame/device tools.

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