create_service_group

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

With no annotations provided, the description carries full burden for behavioral disclosure. It describes a creation operation and return format, but fails to mention error handling (e.g., duplicate group name), required permissions, or whether the group can be updated later. Missing typical concerns for a mutation tool.

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 well-structured: one-line summary, bullet-style Args, Returns, and an example. It is front-loaded with the core purpose, and every sentence is informative. No redundancy or fluff.

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?

The description covers purpose, parameters, return format with keys, and a concrete example. It is fairly complete for a simple create tool, but lacks mention of prerequisites (e.g., whether member services must exist) and conflict behavior. Still, it provides a solid functional contract.

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%, so the description must compensate. It adds meaning by defining each parameter (e.g., 'members: List of service names to include') and clarifying the optional comment. The example further illustrates usage. This exceeds baseline, though param descriptions are brief.

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 'Create a service group' with a specific verb and resource. It distinguishes from sibling tools like create_service_icmp and create_service_tcp_udp by focusing on grouping existing services, making its purpose unambiguous.

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 description does not explicitly state when to use this tool versus alternatives like create_service_icmp or list_service_groups. While the function signature implies grouping, there is no guidance on selection criteria or when not to use it (e.g., for single-service creation).

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