invite_create

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

Since no annotations are provided, the description must disclose behavioral traits. It states the action but does not mention side effects (e.g., sending an email), required permissions, irreversibility, or the return value, leaving the agent without critical behavioral context.

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, front-loaded sentence with no wasted words. It is concise and to the point, though it sacrifices detail for brevity, which is why it does not receive a perfect 5.

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 an invite creation tool, the description is sparse. It does not explain the invite lifecycle (e.g., that invite_accept exists), whether it returns an invite object, or any side effects, making it incomplete for an agent to fully understand the context despite complete parameter documentation.

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 provides descriptions for all three parameters, achieving 100% coverage. The description's mention of 'admin or user' mirrors the group enum but adds no additional semantic value beyond what the schema already documents, so the baseline score of 3 applies.

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's purpose with a specific verb ('Invite') and resource ('a user to join your domain'), and distinguishes it from sibling tools like invite_accept and invite_delete by mentioning the admin/user role option. The action is 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?

No guidance is provided on when to use this tool versus alternatives such as invite_accept or member_update, nor are prerequisites or conditions mentioned. The usage is only implied by the verb, making it insufficient for differentiating usage scenarios.

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