rename_channel

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

The description adds meaningful behavioral context beyond the annotations: the new_name is sanitized to lowercase with hyphens and no spaces, and the tool returns True/False to indicate success. This gives the agent a clear expectation of input transformation and result reporting.

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 compact and well-structured with clear Args and Returns sections. Every line adds necessary information, and the primary purpose appears first.

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 is simple, annotations already convey destructiveness and mutability, and the description covers parameters, sanitization, and return behavior. It is missing only minimal context such as permission requirements or side effects of renaming, but nothing essential is absent for invoking it correctly.

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%, and the description fully compensates by explaining both parameters: channel_id is the target channel ID with format C..., and new_name is the new name with sanitization rules. This is essential information that the schema completely lacks.

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 opens with a specific verb and resource: 'Rename a Slack channel.' This is unambiguous and tells an agent exactly what the tool does. It does not explicitly distinguish from sibling tools like create_channel, but the verb 'rename' is specific enough to avoid confusion.

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?

There is no guidance on when to use this tool versus alternatives, and no mention of prerequisites or exclusions. The agent must infer usage from the name and description alone, which is insufficient for choosing between rename_channel and related channel tools.

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