create_invite

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

No annotations are provided, so the description carries the full burden. It hints at expiration and usage limits (which are really parameter semantics) but says nothing about required permissions (e.g. Manage Channels), whether the invite is bot- or user-authored, or what the operation returns. For an unannotated creation tool this is a notable gap.

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 efficient sentence with the core action front-loaded. Nothing is wasted, though it is arguably too terse to carry the disclosure burden it must.

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?

Parameters are fully covered by the schema, but with no annotations and no output schema the description should compensate by stating permission requirements and the nature of the returned invite code/URL. It omits these, so it is only minimally adequate for a mutation tool.

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 100% and all six parameters are well documented in the schema itself. The description only echoes expiration and usage limits, adding no format or behavioral detail beyond what the schema already provides; baseline 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?

States a specific verb (Create) and resource (invite link for a channel) and notes it supports expiration and usage limits. It is clear what the tool does, but it does not differentiate itself from invite-related siblings like generate_bot_invite_url, list_invites, or get_invite_details.

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 the other invite tools in the sibling list. No prerequisites or contextual conditions are given, leaving the agent to infer usage entirely from the name.

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