create_channel

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

Annotations already indicate this is a mutation (readOnlyHint false) and not destructive. The description adds that it returns the new channel ID, which is useful. However, it does not mention any side effects, permissions, or error behavior. The description does not contradict annotations.

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 with additional parameter hints, all front-loaded. It has no unnecessary words and efficiently conveys the core purpose and key parameter guidance.

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 has 4 parameters, an output schema, and a clear purpose. The description covers the main function and return value, and gives guidance for two parameters. However, it omits guidance for hub_profile_id, which is required. It also doesn't mention how to obtain hub_profile_id, though sibling tools like list_hub_profiles exist. This makes it slightly incomplete for a new 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?

Schema description coverage is 0%, so the description must explain parameters. It explains workspace_id (with a pointer to list_workspaces) and privacy (with allowed values), but it does not explain name (self-explanatory) or hub_profile_id, which is a required parameter with no guidance. This is a significant gap.

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 'Create a new channel in a hub profile' with a specific verb and resource, clearly distinguishing it from sibling tools like update_channel or delete_channel. It also notes the return value, which adds clarity.

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 does not explicitly state when to use this tool versus alternatives, but the context of creating a new channel is clear from the name and purpose. It does not mention exclusions or alternative tools, but the pointer to list_workspaces() provides some usage guidance. Overall, it's implied usage, not explicit.

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