discord_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 does disclose the required permission, which is the single most important pre-flight check for a write tool. It omits other behavioral facts an agent would want — whether names must be unique, what happens on collision, and whether the created channel is returned with an ID.

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?

One sentence, front-loaded with the action and immediately qualified by the permission requirement. No filler and no redundancy with the schema.

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 mutation tool with no annotations and no output schema, the definition covers the essential precondition but not the outcome: whether the new channel object/ID is returned, or how failures (duplicate name, invalid parent_id) surface. Adequate to invoke, thin for interpreting results.

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 100%, including the numeric type enum values and defaults, so the schema already does the heavy lifting. The description adds nothing beyond 'in a server', which maps loosely to guild_id but no syntax or default detail.

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 and resource ('Create a new channel in a server'), which cleanly separates it from the modify/delete/list channel siblings. It doesn't name an alternative explicitly, but the create verb makes the routing obvious.

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 parenthetical gives a real prerequisite (MANAGE_CHANNELS permission), which is more than most definitions offer. However, it gives no guidance on when to pick this over discord_create_dm or when a channel type/category should be chosen, leaving usage implied.

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