create_channel

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 indicates a mutating action by saying 'Create a channel,' but it does not disclose side effects, permission requirements, relationship to the parent team, or what response the agent should expect. For a creation tool with no annotations, this is a significant gap.

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 very short and front-loads the core action. The second sentence about membership_type is useful and earns its place. It could be slightly more structured by also clarifying required parameters, but as written it has no wasted words.

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?

With four parameters, no annotations, and no output schema, this description is too minimal to be fully actionable. It omits that team_id and display_name are required, that membership_type defaults to standard, and what the tool returns after creation. More context is needed for an agent to invoke this tool confidently.

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%, so the description must compensate. It does add value by documenting membership_type allowed values ('standard' or 'private'), which is the most ambiguous parameter. The other parameters (team_id, display_name, description) are reasonably self-explanatory from their names and titles, though no additional semantic detail is provided for them.

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 states a clear verb and resource: 'Create a channel.' This distinguishes it from other tools in the sibling list, none of which create a channel. However, it does not explicitly mention that this is a Teams channel or that the channel belongs to a team, leaving some context to be inferred from the schema and sibling tool names.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites such as an existing team or required permissions. It simply states the operation and a parameter value, leaving usage decisions entirely to the agent.

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