mdl_watchlist_fetch_page

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the meaningful auth requirement, but omits pagination behavior, page limits, and whether the result set is bounded.

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?

Two short, front-loaded sentences with no filler. Its brevity is efficient, though it tips toward under-specification rather than being tight-but-complete.

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 an authenticated, paginated fetch tool with no output schema and undocumented parameters, the description should cover paging behavior and what the status filter scopes. It leaves those entirely to inference.

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% and there are two parameters. The description does not explain the required 'status' enum (watching, plantowatch, etc.) or what page numbering/max means, so it fails to compensate for the schema's lack of parameter documentation.

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 verb (fetch) and a resource (watchlist page), so the basic action is legible. But it does not differentiate from siblings like mdl_watchlist_fetch or mdl_users_get_user_watchlist, and 'page' is only clarified by the schema's page parameter rather than the prose.

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 only guidance is the authentication prerequisite ('Requires host-configured MyDramaList authentication'), which is useful but not usage guidance. There is no statement of when to use this tool versus mdl_watchlist_fetch or the other watchlist/status siblings.

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