Create Discord channel

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

Annotations already disclose that this is a non-read-only, non-idempotent, open-world operation. The description adds only the channel type list and does not explain the confirm parameter, permission requirements, side effects, or what happens if a channel with the same name exists.

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 appropriately sized but minimal, leaving substantial gaps that are not addressed elsewhere in the description.

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 12-parameter creation tool with no schema descriptions and no annotation-level permission detail, the description is far too thin. An output schema exists, but input-side semantics and behavioral requirements are largely missing.

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 0% across 12 parameters, yet the description only restates the type enum values already present in the schema. It provides no meaning for guildId, name, parentId, nsfw, topic, reason, bitrate, userLimit, rateLimitPerUser, or confirm.

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 a specific verb and resource ('Create ... channel') and enumerates the supported channel types. It is clearly distinguishable from sibling mutation tools like discord_update_channel and discord_delete_channel, though it does not explicitly name alternatives.

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 related tools, no mention of required permissions, and no explanation of prerequisites such as parentId requirements for voice/forum/stage channels. Usage is only implied by the verb 'Create'.

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