Create Workspace Invitation

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

The annotations already indicate destructiveHint=true and openWorldHint=true, so the agent knows this is not a read-only operation. However, the description itself adds no behavioral context beyond 'send', such as what consequences sending an invitation has, whether it is reversible, or what side effects occur. It does not contradict the annotations.

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 extremely short and front-loaded, with no wasted words. While it is arguably too terse to be fully useful, as a concise statement of the core action it is well-structured and immediately scannable.

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 tool with a nested request body, a required email, an optional role enum, and no output schema, this description is incomplete. It does not mention required fields, role semantics, what happens after sending, or any distinction from related invitation tools, leaving the agent to infer critical context.

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 description coverage is only 50%, and the only property description, 'The JSON request body', is generic and unhelpful. The tool description does not explain workspaceSlug, email, role, or how they relate, so it adds no meaning beyond the raw schema fields.

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 ('Send') and resource ('workspace invitation'), making the tool's function clear and distinguishing it from workspace-creation and invitation-management siblings like createWorkspace, revokeWorkspaceInvitation, and acceptInvitation. It is not a tautology and adds a slight action-oriented nuance beyond the tool name.

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 about when to use this tool versus alternatives such as revokeWorkspaceInvitation, listWorkspaceInvitations, acceptInvitation, or declineInvitation. The usage is only implied by the tool name and one-line description, with no mention of prerequisites, context, or exclusions.

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