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

No annotations are provided, so the description carries the full burden. It usefully discloses the return payload (complete record with full synopsis, versus the presumably thinner search results), but says nothing about invalid-id behavior, permissions, or error handling for a lookup that can fail.

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?

A single, front-loaded sentence with no filler — the resource, the payload scope, and the id source all in one clause. Nothing needs trimming.

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 one-parameter read tool with no output schema, the description covers what is fetched, from which id, and where that id originates. Only failure/error behavior is absent, which is a minor gap for a getter.

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 0% and the schema only types film_id as an integer, so the description must compensate. It does add provenance ('le film_id de search_films'), which tells the agent where to obtain the value, but gives no format, range, or validity details beyond that.

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?

States a specific verb+resource ('Retourne la fiche complète d'un film') and scopes the payload ('synopsis intégral'), which clearly separates it from the search tool. It does not explicitly name what it is not, but the sibling reference to search_films supplies the contrast.

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?

Saying the film_id comes from search_films implies the intended workflow (search first, then retrieve full record), but there is no explicit when-to-use/when-not or statement of prerequisites. The guidance is inferred rather than stated.

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