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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It usefully reveals that tokens are single-use, expiring, limited to 1-10, and consent-based, but it does not discuss authentication requirements, side effects of creating tokens, or what the caller should expect in return.

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, tightly written sentence with no filler. The main verb, resource, constraints, and purpose are all front-loaded, and every word contributes to comprehension.

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 four simple parameters and no required fields, the description provides enough to attempt a default invocation. However, with no output schema, it does not describe the return shape or how the created tokens are meant to be used, leaving a meaningful gap for an agent planning a multi-step workflow.

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 low (25%), so the description must compensate. It reinforces the count range ('1-10') and adds 'expiring' semantics tied to token validity, but it does not explain the note parameter or explicitly map expiration behavior to ttl_hours. The intended_recipient field is already described in the schema.

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 names the action ('Create'), the resource ('invitation tokens'), and the key constraints ('1-10', 'single-use', 'expiring'). It also adds the 'consent-based agent-to-agent delivery' context, which clearly distinguishes it from the debate-focused sibling tools like join, propose, and vote.

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 phrase 'for consent-based agent-to-agent delivery' gives clear context for when this tool is appropriate. It does not explicitly compare with alternatives or state when not to use it, but no sibling appears to perform the same function, so the context is sufficient.

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