discord_create_channel

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false. The description adds the permission requirement and confirms a mutation with a return value, but doesn't disclose non-idempotency or destruction scope. With annotations covering the safety profile, the added value is modest.

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?

Very concise and front-loaded: the core action is stated first, then the permission requirement, then the return value. Two sentences with no waste, though the return-value line is a bit redundant given an output schema exists.

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 7-parameter mutation tool with no annotations covering permissions, the description could say more about required Discord permissions, the effect of each type value, or how the channel placement works. With an output schema present, the return description is unnecessary. Adequate but not complete.

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 coverage is 86% – the schema already documents all 7 parameters, including the enum for 'type' and descriptions for name, topic, reason, guild_id, parent_id. The description adds no parameter-level details beyond what the schema provides, so baseline 3 is appropriate.

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+resource: 'Create a channel or category in a server.' This clearly distinguishes it from siblings like discord_edit_channel or discord_delete_channel, which are non-create operations on the same resource.

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?

Names the required permission (Manage Channels) but offers no when/when-not guidance or references to alternatives. For instance, it doesn't say to use discord_create_thread instead for forum-like threads, nor when to create a category vs. a channel. Implied usage only.

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