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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description's only behavioral claim ('revalidate publication') is ambiguous and adds no concrete context such as whether validation gates the response, what triggers failure, or auth requirements.

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?

It is a single short sentence with no wasted words, so it is concise. However, the sentence is front-loaded with an obscure 'revalidate' clause rather than the resource/action, weakening structure.

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?

Although an output schema exists (so return values needn't be described), the tool has a required id plus a nested filter object and explorer_id, and the description leaves all of that and the usage context unexplained. It is far too thin for a nested-parameter, multi-sibling catalogue tool.

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%, and the description provides no meaning for any of the four parameters (id, filters, language, explorer_id) or the many nested FilmFilters fields. With low coverage the description is expected to compensate, and it does nothing here.

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 gestures at 'public editorial film details' but never states a clear verb+resource operation; 'Revalidate publication before displaying' is an odd framing that doesn't map to a recognizable action like 'fetch one film's details by id'. It does not differentiate itself from siblings such as catalogue_search, catalogue_related, get_documentary, or open_catalogue.

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?

There is no statement of when to use this tool versus the many sibling catalogue/search tools, no prerequisites, and no exclusions. The phrase 'before displaying' hints at a pre-display step but gives no actionable condition for selecting this tool.

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