Get watchlist

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

The readOnlyHint and openWorldHint annotations already establish the safety profile. The description adds that the watchlist belongs to the authenticated user, implying authentication and personal data scope, but it does not describe pagination behavior, default ordering, or error cases.

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 a single front-loaded sentence with no filler or repetition. Every word contributes directly to identifying the tool's resource and scope.

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 annotations cover the read-only nature, and the schema documents several pagination and filtering parameters. However, with no output schema and three parameters lacking schema descriptions, the description is still minimal for a tool with nine optional parameters and does not explain the returned item structure.

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 moderate at 67%, and the description adds no parameter meaning at all. Parameters such as sort, order, and mediatype have only enums and no descriptions, so the description does not compensate for those gaps.

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 specific verb and resource: get the authenticated user's watchlist items. It is clear what the tool retrieves, though it does not explicitly differentiate itself from sibling tools such as get_list_items or get_user_lists.

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 gives no explicit guidance on when to use this tool versus alternatives. It does not mention add_watchlist_items, remove_watchlist_items, or custom-list alternatives such as get_list_items.

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