justwatch_monetization_titles

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

With no annotations provided, the description carries the full burden. It states the return is 'popular titles for one monetization type' but does not disclose read-only nature, output format, or any limitations beyond parameter validation.

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 extremely concise with two short sentences that cover purpose and key parameter constraints. No unnecessary 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?

Given the lack of annotations and output schema, the description is adequate but leaves gaps: it does not describe the structure of the returned titles, potential errors, or prerequisites. It covers the bare minimum.

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?

Even though schema coverage is 100%, the description adds value by explicitly listing the allowed values for monetization_type and type, which are not enforced via enums in the schema. This provides clearer guidance beyond the schema descriptions.

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 verb (Get), resource (JustWatch monetization titles), and scope (for one monetization type). It focuses on a specific functionality distinct from sibling tools like justwatch_popular or justwatch_search.

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 provides parameter constraints but does not explicitly state when to use this tool versus alternatives such as justwatch_popular or justwatch_provider_titles. Usage context is implied but not explicitly outlined.

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