Create Project Distribution Group

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

The description adds that it returns the created object and mentions HTTP 201, which is consistent with annotations (readOnlyHint false). However, it does not elaborate on potential side effects given openWorldHint true, nor does it disclose permissions or error cases.

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 mostly concise and front-loaded, but it contains some repetition ('new Directory records' used twice). It efficiently includes API endpoint and response status.

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 core purpose, required params, and returns, but lacks details on prerequisites, permissions, and the return structure (output schema missing). For a 5-parameter tool, more completeness would be beneficial.

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 already covers all parameters (100% coverage). The description reiterates required parameters but adds no additional semantic value beyond what the schema provides.

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 the tool creates a new Distribution Group associated with a given Project, specifying required parameters and the API endpoint. It is distinct from siblings like delete or show distribution group tools.

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 context to use the tool for creating a distribution group but lacks explicit when-not or alternative tool guidance. Given the large number of sibling tools, clearer usage boundaries would help.

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