get_movie_by_movie_id_ratings

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

Annotations already declare readOnlyHint=true and idempotentHint=true, covering safety. The description adds the HTTP GET method and path structure, which is mild additional context but not substantial behavioral disclosure beyond 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 extremely concise, with the key information (method, path, parameter) front-loaded. No wasted words or repetitive content.

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 tool is a simple read operation with a single parameter and output schema exists, the description is mostly complete. However, it could clarify the ID type (TMDB vs internal) and note the difference from combined ratings. Since output schema exists, return format is covered.

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. It only restates that movie_id is a path parameter, adding minimal semantic meaning. It doesn't explain that movie_id typically refers to a TMDB ID or provide format or type details 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 retrieves movie ratings, using a specific verb and resource. It distinguishes from siblings like get_movie_by_movie_id and get_movie_by_movie_id_ratingscombined by specifying this is for ratings only.

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 the HTTP method and path, implying usage context but no explicit when-to-use guidance or alternatives. It doesn't mention that get_movie_by_movie_id_ratingscombined might be a more comprehensive alternative for combined ratings.

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