Create an invite link

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

Annotations only include openWorldHint, with no readOnly or destructive hints, so the description must disclose side effects. It only says 'generate' without mentioning permissions, irreversibility, rate limits, or what happens to existing links. This is similar to the TDQS 2.9 example where mutation tools require more transparency.

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?

A single, front-loaded sentence precisely conveys the tool's core function and options without redundancy. Every word contributes, making it highly concise and well-structured.

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?

With 6 parameters, no output schema, and minimal annotations, this description is notably incomplete. It does not mention the return value (the invite link), prerequisites for the `peer` parameter, or how the options interact. It also provides no context about when to create versus revoke links, leaving the agent with significant gaps.

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 33% (expireDate and requestNeeded have descriptions). The description adds meaning for expireDate, usageLimit, and requestNeeded via 'expiry, usage cap, and join-request gate', but it omits the required `peer` param and optional `title`/`accountId`. For expireDate and requestNeeded, it mostly repeats the schema descriptions, so the added value is minimal.

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 action ('Generate a new invite link') and distinct resource, making its purpose unmistakable. It also mentions key customization options (expiry, usage cap, join-request gate) that differentiate it from sibling tools like list_invite_links and revoke_invite_link.

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 explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. While the name implies creation, the description lacks context such as 'use this instead of list_invite_links when you need a new link' or notes about required peer type.

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