AddChannelCatalog

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

With no annotations, the description must disclose behavioral traits. It does not mention whether the operation is destructive, requires authentication, or has side effects. The single sentence provides no behavioral context beyond the bare 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 very short (one sentence), which is concise but lacks any structure or additional details that would help the agent. It is not wasteful but is underspecified.

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 large set of sibling tools and the absence of an output schema or annotations, the description is incomplete. It does not explain what a channel catalog is, what parameters are needed in the body, or what the expected result is.

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 one parameter 'body' with a vague description 'Request body'. The tool description does not add any meaning to this parameter, such as what fields are expected or the structure of the body. Schema coverage is 100% but the param description is unhelpful, and the tool fails to compensate.

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 'Add' and the resource 'channel catalog', matching the tool name. It distinguishes from siblings like DeleteChannelCatalog or ConfigureChannelCatalog by indicating creation. However, it is minimal and could be more explicit.

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 on when to use this tool vs alternatives like ConfigureChannelCatalog or EnableChannelCatalog. The description provides no context about prerequisites or typical usage scenarios.

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