user_invitations_create

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

With no annotations, the description must carry the burden of transparency. It discloses that the created invitation 'expires in ~3 days' and that it returns 'Created user invitation information'. However, it does not mention permissions, prerequisites, or side effects like email delivery, so transparency is partial.

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 with Args and Returns sections. It is concise overall, though the '[Users/Invitations]' prefix is redundant and adds minor clutter. Each line in the Args section provides useful information, so it earns a slightly above-average score.

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 tool has 3 parameters, one of which is a nested object, and an output schema exists. The description provides some return context ('expires in ~3 days') but does not explain the structure of invitation_data, which is critical for correct invocation. Given the lack of annotations and schema descriptions, the description is incomplete for complex usage.

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 schema has no property descriptions (0% coverage), so the description must compensate. It adds meaning by identifying invitation_data as a dictionary, include as an optional list of related resources, and visible_apps_limit with a 1-50 range. However, 'Dictionary containing the invitation details' is vague and does not specify required keys, leaving gaps in parameter understanding.

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 new user invitation' with a specific verb and resource. This distinguishes it from sibling tools like user_invitations_list, user_invitations_get, and user_invitations_delete, leaving no ambiguity about its function.

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 statement about when to use this tool versus alternatives, but the purpose implies its use for creating invitations. No exclusions or alternative references are provided, so guidance is limited to what is inferred from the name and description.

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