contacts_create_group

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It only states the action without mentioning permissions, idempotency, duplicate handling, side effects, or any other behavioral traits that would help the agent anticipate the consequences of invoking the 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 a single, direct sentence with no unnecessary words. It is front-loaded with the verb and object, making it immediately readable. For a simple one-parameter creation tool, this conciseness is ideal.

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?

Although an output schema exists, the description lacks essential contextual information: no usage guidelines, no behavioral details, and no constraints or prerequisites. For a tool with zero annotations, the description is insufficient to give the agent a complete understanding of when and how to use it safely and correctly.

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 input schema has 0% description coverage for the 'name' parameter, and the description does not mention or explain the parameter at all. While the parameter name is relatively self-explanatory in the context of creating a group, the description adds no semantic meaning or usage hints beyond the schema field itself.

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 ('Create') and resource ('contact group'), clearly stating the tool's function. It distinguishes from sibling tools like contacts_create (likely for contacts) and contacts_list_groups, making the 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 provides no guidance on when to use this tool versus alternatives, lacks exclusions, and does not mention prerequisites or typical use cases. The usage is left entirely to inference from the tool name and description, which is minimal.

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