update_actions_remove_from_continue_watching

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

Annotations already indicate this is a write, idempotent, non-destructive operation. The description adds only the HTTP method and path, with no extra behavioral context such as side effects, auth requirements, or what happens when the key is absent.

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 short and front-loaded, with the endpoint and parameter listed cleanly. However, the opening sentence mostly repeats the tool name, leaving room for more substantive content 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?

For a simple one-parameter action with annotations and an output schema, the description provides the minimum viable information. It lacks usage context, alternative differentiation, and clarification of nullable key behavior, but the endpoint and parameter meaning are sufficient for a straightforward call.

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 'Args' line carries the burden. It does add that 'key' is 'The metadata key of the item', which is useful, but it doesn't clarify optionality, format, or the effect of a null key—especially important since the parameter is not required.

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 ('Remove From Continue Watching') and provides the exact HTTP endpoint. The target resource ('Continue Watching') distinguishes it from sibling watchlist tools, though it doesn't explicitly call out that distinction.

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 given about when to use this tool versus alternatives like create_actions_remove_from_watchlist, nor are prerequisites or context mentioned. The agent must infer usage entirely from the name and endpoint.

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