get_movies_by_id_aliases

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false. The description adds no behavioral detail beyond the endpoint path and parameter; it does not mention response behavior, pagination, or access requirements. It does not contradict the annotations, but it also does not enrich them.

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?

Extremely concise and front-loaded. The purpose appears in the first sentence, and the endpoint plus Args section add necessary call details without waste.

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 single-parameter, read-only endpoint with an output schema and safety annotations, the description is nearly complete. It gives the endpoint, the parameter semantics, and the purpose. It lacks only usage context and a concrete example, which are minor for this 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%, so the description must compensate. It minimally clarifies that 'id' accepts either an ID or slug, which the bare schema does not convey. However, 'the resource' is vague, and there is no example or format detail.

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 and resource: 'Get all movie aliases.' It clearly identifies the operation and the target (a movie by ID/slug), and is distinguishable from the sibling get_shows_by_id_aliases by the explicit 'movie' scope.

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 guidance is provided about when to use this tool versus alternatives such as get_shows_by_id_aliases or other alias-related endpoints. There are no prerequisites, exclusions, or context cues beyond the name itself.

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