create_channel

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

No annotations are provided, so the description must disclose behavioral traits. It highlights a key requirement ('requires app installation') but omits other important details such as expected response, side effects, permissions, or failure modes. It adds minimal transparency beyond the basic action.

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 a single, front-loaded sentence that clearly states the purpose and a key requirement. Every word earns its place; there is no redundancy or unnecessary detail, making it highly concise and well-structured.

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 simple create operation with three documented parameters, the description is minimally adequate. It lacks explicit usage guidance and return value information, but since there is no output schema, a brief description may be acceptable. However, given the absence of behavioral detail and alternatives, it is not fully contextualized for an agent.

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?

The input schema provides descriptions for all three parameters, giving 100% coverage. The tool description does not add any extra parameter meaning beyond what the schema already offers. Baseline of 3 is appropriate since the schema fully documents the parameters.

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 the action ('Create') and the resource ('a new sales channel'). It also adds a prerequisite ('requires app installation') which helps distinguish it from related tools like get_channel or update_channel. Although it doesn't explicitly name sibling tools, the verb and resource make the purpose unambiguous.

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: one would call this to create a sales channel. It does not explicitly mention alternatives or when not to use it. The prerequisite hints at a condition but does not explain when a user should choose this over other channel-related operations, so guidance is basic but not misleading.

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