Behavior2/5

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

No annotations exist, so how the description carries the full disclosure burden. It only states that a channel is created, which implies mutation, but never discloses the effect of a voice — such as requiring server manage permissions, live creation of this channel, default override semantics, or consequences of duplicate names. Genuine behavioral context is absent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The sentence is short and front-loaded, but the tool is a mutating operation with 8 parameters; a one-line restatement of the name is notiically under-specified rather than concise. The single sentence does not earn its place beyond repeating what the name already says.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Although an output schema exists, the description provides none of the context needed to call the tool correctly: whichappings are required vs optional, how 'guil_id' selects the target server, how 'category_id' positions the new channel, or how this slot among more than fifty Discord sibling tools should be chosen. Essential targeting information is completely missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% for 8 parameters, so the description must compensate — and it mentions no parameters at all. An agent invoking the tool gets no semantic-bound information about the required 'name' parameter, 'guild_id' targeting, or optional 'bitrate' and 'user_limit' behaviors.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create a voice channel' is a pure restatement of the tool name — same verb, same resource — and adds zero information beyond it. The intent is clear, but it fails to distinguish the tool from its create_* siblings and qualifies as a tautology.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus discord_create_text_channel, discord_create_category, discord_create_forum, or discord_edit_channel. It lacks prerequisites (such as needing a valid guilguid) and provides no exclusion criteria for the agent.

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