create_group

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

No annotations are provided, so the description must carry the behavioral transparency burden. It only states that a new group is created and describes arguments; it does not disclose side effects, whether the operation is destructive, permission requirements, or behavior on name conflicts. For a mutation tool, this is a meaningful gap.

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 compact, front-loaded with the core action, and uses a clean Args block. Every sentence adds value with no fluff or repetition.

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 simple create tool with only two parameters, the description covers the essential purpose and argument semantics completely. An output schema is present, so return value details are not the description's responsibility. Minor gaps are the lack of usage alternatives and behavioral caveats, but the tool is still callable correctly from the given information.

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 is the only source of parameter meaning. It clearly explains 'name' as the display name and 'light_ids' as an optional initial list with a concrete example (["1", "3", "5"]), fully compensating for the bare schema.

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 opens with a specific verb and resource: 'Create a new light group.' This unambiguously distinguishes it from sibling tools like modify_group, delete_group, and list_groups, and leaves no doubt about the operation performed.

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?

The usage is implied by the verb 'Create' and the resource 'light group,' but the description does not explicitly state when to choose this tool over alternatives such as modify_group or set_group_action. There is no mention of prerequisites, limitations, or what to do if a group already exists.

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