remove_from_watchlist

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

Annotations already provide key behavioral hints (destructive, idempotent, read-only is false). The description adds value by clarifying the operation is scoped to the authenticated user and explicitly notes that removal is verified, which is not present in the annotations.

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 tightly written sentence with no filler. The core action is front-loaded, and 'and verify it' adds meaningful post-condition information without unnecessary verbosity.

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 destructive mutation, the description and annotations cover the essential operation. However, it leaves title_id semantics undocumented, does not explain what verification entails, and provides no output or error context despite there being no output schema.

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 description must compensate, but it never explains title_id, its format, how to obtain it, or its relationship to the 'title' being removed. The only hint is the parameter name itself, which is not enough.

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 uses a specific verb ('Remove') with a clear resource ('a title from the authenticated user's IMDb Watchlist') and adds a verification post-condition. This clearly distinguishes it from sibling tools like add_to_watchlist and list_my_watchlist.

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 does not state when to use this tool versus alternatives such as add_to_watchlist or list_my_watchlist, and it provides no prerequisites or exclusions. The intended use is implied by the name, but there is no explicit routing guidance.

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