create_channel

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

With no annotations provided, the description must disclose behavioral traits. It details the channel_type integer mapping, but omits side effects (e.g., success behavior, return value), permission requirements, or handling of duplicate names. It lacks depth for a creation tool.

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 two sentences, front-loaded with the primary action, and the second sentence efficiently lists channel_type enumerations. No redundant information.

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?

Given the tool's complexity (6 params) and lack of annotations, the description covers only the channel_type facet. It does not mention required permissions (e.g., MANAGE_CHANNELS), the relationship between parent_id and channel_type, or default behavior for guild_id. The output schema exists, covering return structure, so that gap is mitigated, but overall completeness is moderate.

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%, but the description partially compensates by explaining channel_type values, which is highly valuable. Other parameters like name, topic, reason, guild_id, and parent_id are not explained beyond their self-explanatory names, leaving semantic gaps (e.g., guild_id default meaning).

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 'Create a new channel in the server' with a specific verb and resource, distinguishing it from sibling tools like edit_channel or delete_channel. The explicit channel_type enumeration adds specificity, clarifying the tool's scope.

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 implies usage (to create a channel) but offers no explicit guidance on when to use this tool versus alternatives, prerequisites like permissions, or cases to avoid. The channel_type mapping provides some context but not comparative usage details.

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