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

Annotations cover read-only and open-world behavior, so the baseline is lower. However, the description is silent on what data is returned (e.g., runtime, sound mix, aspect ratio, color), what 'technical specs' means in this context, or any rate/authentication considerations. It adds no behavioral context beyond the title.

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 brief and front-loaded, but it is under-specified rather than concise. It does not waste words, but it also does not provide useful information.

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?

An output schema exists, so return values need not be explained, but the description is incomplete for a title-specs tool in a large family of IMDb tools. It doesn't clarify whether it takes a title ID or URL, what such specs include, or how it relates to similar tools.

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 neither parameter is described. The description does not explain what the 'id' or 'url' parameters should contain, what format they take, or whether they are mutually exclusive. With 0 parameters required, a baseline of 4 might apply, but the total absence of any guidance on these two optional identifiers is a significant gap.

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 states a resource ('IMDb title technical specs') but provides no verb and no differentiation from the many sibling tools (imdb_title, imdb_title_box_office, etc.). An agent knows the topic but not the action or 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 indication of when this tool should be used versus alternatives, nor what a 'technical specs' query entails. No prerequisites, no exclusions, no routing guidance.

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