user_invitations_create_instance

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

With no annotations supplied, the description carries the full burden of behavioral disclosure yet says nothing beyond the HTTP method. It omits whether an email/invitation is actually sent, what permissions are required, side effects, or idempotency behavior.

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?

It is short but wastes its single sentence on a redundant parenthetical repetition of the same path '(POST /v1/userInvitations)' and never front-loads an actual purpose statement.

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 mutation tool with no annotations, no output schema, and an opaque nested body, the description is far too thin. An agent cannot determine the effect of the call, required auth, or response from this definition.

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?

There is one parameter with 100% schema description coverage, so the schema baseline of 3 applies. The description merely echoes the schema pointer (components.schemas.UserInvitationCreateRequest) without adding any syntax, required-field, or envelope detail beyond what the schema already states.

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 only restates the HTTP endpoint (POST /v1/userInvitations) and does not state in plain language that it creates a user invitation or what one is. It is essentially a tautological restatement of the tool name rather than an explanation of the operation.

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 guidance on when to use this tool versus alternatives such as beta_tester_invitations_create_instance or the various other create_instance siblings. No prerequisites, context, or exclusions are provided.

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