get-movie-details

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Get details', which implies a read operation, but it does not mention safety (e.g., read-only, no side effects), required authentication, rate limits, or error conditions. This is insufficient for a tool without 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 sentence with no fluff. It is front-loaded with the core action. However, it could be slightly longer to improve completeness without sacrificing conciseness.

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 tool with no output schema, the description is minimal. It does not explain what 'details' include (e.g., cast, ratings, plot) or the structure of the response. Given the singular purpose and sibling tools, more context on the type of returned data would improve completeness.

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?

The schema covers 50% of parameters with descriptions (movieId has one, language does not). The description does not add any additional meaning to the parameters, such as explaining the movieId format or language defaults. Given low schema coverage, the description should compensate, but it does not.

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 it retrieves details for a specific movie using the TMDB API. The verb 'Get' and resource 'details for a specific movie' are present. It distinguishes from sibling list tools (search, trending, recommendations, discover) by emphasizing 'specific movie', though it could explicitly name the alternatives.

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 implies use when you need details for one specific movie, contrasting with siblings that return lists. However, it does not explicitly state when not to use this tool or name the alternatives. The context of sibling tools is provided separately, but the description itself lacks guidance.

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