remove_from_watchlist

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

No annotations are provided, so the description carries the burden. It discloses the requirement for PLEX_ENABLE_MUTATIVE_OPS, which is a behavioral constraint, but does not mention side effects (e.g., idempotency, potential errors if item not found) or authentication needs. Minimal but not misleading.

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 sentence that is front-loaded with the action and includes the critical prerequisite. No wasted words.

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 mutative tool with one parameter and no output schema, the description is mostly complete. It covers what the tool does and the mutative requirement. Minor gaps exist (e.g., behavior on non-existent items), but overall it is adequate.

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 coverage is 100% for the single parameter ratingKey, and its description already explains what it is. The tool description adds no extra meaning beyond the schema, so the baseline score of 3 applies.

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 the specific action ('Remove') and target ('media item from watchlist'), clearly distinguishing it from sibling tools like add_to_watchlist and get_watchlist. The verb and resource are explicit and unambiguous.

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 notes a prerequisite (PLEX_ENABLE_MUTATIVE_OPS=true), which provides important usage context. It doesn't explicitly mention when not to use it or alternatives, but the purpose is clear enough that an agent would know when to invoke it.

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