list_hubs_continue_watching

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

The description is compatible with the annotations (read-only, non-destructive), but it adds no behavioral nuance beyond the GET endpoint. It doesn't mention authentication expectations, empty results, or why this hub differs from related functions, so it only minimally complements the annotation coverage.

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, uses the action-first structure with the GET endpoint provided. There is essentially no waste, though the endpoint line is arguably redundant given the description statement. It is front-loaded and readable.

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 tool's simplicity, the zero parameters, and the output schema, the description provides the basic expected information. However, the ambiguous relationship to sibling list_hubs_continue_watching_items is not addressed, so the agent may be unsure what differentiates this tool from that one.

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 tool has zero parameters, so the description does not need to explain parameter behavior. The schema already reflects this fully, and there is nothing to compensate for. This follows the baseline for a tool without 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 states a clear verb and object: 'Get the continue watching hub.' This is specific enough to identify the resource, though it doesn't explicitly differentiate from the sibling list_hubs_continue_watching_items. The endpoint line provides extra specificity.

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?

There is no guidance about when to use this tool over list_hubs_continue_watching_items, list_hubs, or other hub tools. The agent is left to infer the distinction from the name and endpoint, and the description gives no explicit usage context.

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