create_channel

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

The annotations already indicate that this is not read-only and not destructive, and the description aligns with that by stating it creates a channel. However, it adds little beyond that: no mention of required permissions, rate limits, server limits, or side effects. The description 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 a single front-loaded sentence with no filler. It leads with the action and resource, then gives the most important payload contents, making it easy for an agent to parse quickly.

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 two-parameter tool, the description is minimally viable: it identifies the resource, the target guild via guild_id, and hints at the payload shape. However, it omits cross-references to update_channel/delete_channel, expected return value, and permission requirements, leaving notable gaps for an agent unfamiliar with Discord's API.

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 schema has 0% description coverage and data is an unconstrained object, so the description must compensate. It does add useful meaning by listing 'name' and 'optional type or permission_overwrites', but it leaves gaps around the required fields inside data, the format of type, and the meaning of guild_id beyond its name.

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 states the exact action and resource: 'Create a server channel', which clearly distinguishes it from sibling tools like update_channel, delete_channel, and create_thread. It also names the primary data fields, giving an agent a concrete idea of what the tool produces.

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 given about when to use this tool versus alternatives such as update_channel, create_thread, or delete_channel. There is no mention of permission prerequisites, Discord server context, or situations where channel creation would be appropriate.

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