Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether changes are immediate and permanent, what permissions are needed, or what happens to settings not explicitly provided (e.g., if only name is given, do topic and category reset?). The tool mutates state but no warnings are given.

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

Conciseness4/5

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

The description is a single sentence of 12 words, concise and front-loaded. However, it omits crucial details that could be added without making it verbose, so it's not maximally efficient.

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

Completeness2/5

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

Given 5 parameters (100% schema coverage, no output schema), the description is too brief. It does not explain the 'server' parameter's optionality or the special behavior of the 'category' parameter. For a tool that modifies a channel, more context is needed to ensure correct invocation.

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

Parameters3/5

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

Schema coverage is 100%, so baseline is 3. The description adds meaning by linking parameters to actions (name→rename, topic→change topic, category→move), but it does not clarify the 'server' parameter or that an empty category removes from category. Marginal improvement over schema.

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

Purpose4/5

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

The description clearly states the tool edits a channel by renaming, changing topic, or moving it into/out of a category. It distinguishes from sibling tools like create_channel or delete_channel, but could be more explicit about it being for existing channels only.

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?

No guidance on when to use this tool vs alternatives (e.g., edit_server for guild-level changes). No prerequisites or conditions mentioned, such as required permissions or that the server must be specified when the bot is in multiple servers.

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