voicebox_create_channel

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

With no annotations and only two words in the description, there is zero disclosure of behavioral traits such as whether the operation is destructive, requires authentication, or triggers side effects. The agent has no insight into what happens when the tool is invoked.

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 extremely concise (one sentence, six words), but it sacrifices informational value. It is front-loaded, yet fails to earn its brevity by missing critical context. Adequate for a simple tool, but could be more informative in the same space.

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?

Given the complexity of the Voicebox ecosystem with over 80 sibling tools, this description is incomplete. It does not explain the role of a channel, how it relates to profiles or stories, or what the output schema returns. The agent is left without sufficient context to use the tool effectively.

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 has 100% coverage with clear descriptions for both parameters (name and is_default). The tool description adds no additional meaning beyond the schema, so it meets the baseline expectation but does not exceed it.

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 'Create a new channel' explicitly states the action and resource, but it's essentially a tautology of the tool name. It lacks context about what a channel is within Voicebox, making it adequately clear but not distinctive enough to earn a higher score.

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?

No guidance is provided on when to create a channel versus using other tools (e.g., voicebox_update_channel). There are no prerequisites, exclusions, or alternatives mentioned, leaving the agent without direction on proper use.

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