create_channel

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

With no annotations, the description carries the full burden. It discloses the WRITE nature and the DISCORD_MCP_ENABLE_WRITE gate, which is useful, but it omits details about required permissions, failure behavior, or side effects beyond creation.

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 that packs the essential gate, verb, resource, and type flexibility without any fluff. Every word adds value.

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?

The tool has moderate complexity with 5 parameters and no output schema description, but the existence of an output schema covers return values. The description lacks guidance on optional parameters and permission requirements, making it only minimally 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?

The schema has 5 parameters with 0% description coverage. The description partially explains `type` (any Discord-valid int) and implies `guild_id` via 'in a guild', but it does not clarify `name`, `topic`, or `parent_id`, leaving most parameters unexplained.

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 tool creates a channel, a specific resource, and specifies the supported types (text/voice/category) via any Discord-valid `type` int. This distinguishes it from sibling tools like list_channels, edit_channel, and delete_channel.

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?

The description clearly indicates the tool is for creating channels, and the write gate provides a prerequisite context. However, it does not explicitly mention when not to use it or reference alternatives like edit_channel for modifications.

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