set_lighting

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 disclosing behavior. It only indicates that properties are set and lists examples; it omits whether the operation requires an open place, whether changes are permanent, what happens on invalid property names, or what the return value looks like.

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 wasted words. The trailing ellipsis is slightly unhelpful, but otherwise the structure is efficient.

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?

For a mutation tool with a nested object parameter, no annotations, and no output schema, the description is too thin. An agent would still lack essential context such as required permissions, the shape of the 'properties' object, and how to handle unknown property names.

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 coverage is 0% and the only parameter ('properties') is an undocumented nested object. The description partially compensates by listing example property names (ClockTime, Brightness, Ambient, etc.), but it does not explain the expected map structure or value formats.

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 states a specific verb ('Set') and resource ('Lighting properties'), and gives concrete examples of the properties involved. It distinguishes itself from 'get_lighting' by the verb, but does not explain how it differs from siblings like 'set_property' or 'set_properties'.

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 explicit guidance on when to use this tool versus alternatives such as 'set_property' or 'set_properties'. The reader must infer usage from the name and description alone, with no conditions or exclusions provided.

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