justwatch_genre_titles

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

No annotations provided. Description confirms it returns data (read operation) but does not disclose any behavioral traits like rate limits, auth, or side effects. 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?

Two sentences that are clear and front-loaded. Every word adds value with no unnecessary details.

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?

With 5 parameters, 1 required, and no output schema, the description covers the core functionality. It lacks details on pagination or result format, but for a simple query tool, 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% (all 5 parameters described). Description adds a concrete example for the 'genre' parameter and clarifies the 'type' parameter's valid values, which enhances understanding beyond the schema.

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 tool's purpose: getting popular titles for a JustWatch genre short name. It provides an example ('act') and distinguishes from sibling tools like justwatch_genres.

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?

No explicit guidance on when to use this tool versus other JustWatch tools (e.g., justwatch_popular or justwatch_discover). Usage is implied but not contrasted with alternatives.

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