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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds no behavioral context beyond that — no mention of which identifier form resolves, whether both id and url are alternatives, or what the awards payload covers. It does not contradict the annotations, but it contributes nothing.

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 three-word fragment is not padded, but this is under-specification rather than conciseness. Nothing is front-loaded because nothing substantive is present.

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 described, but for a tool with two undocumented, optional identifier parameters and no usage context, the definition leaves an agent unable to decide which parameter to supply. It is not adequate for correct invocation.

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% for both parameters (id, url), so the description must carry the burden of explaining them, and it explains neither. In particular it never clarifies whether 'id' is an IMDb tt-id, whether 'url' is an alternative lookup path, or which one takes precedence.

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 'IMDb title awards' merely restates the tool name in expanded form; it names the resource (awards) but supplies no verb, no scope, and no differentiation from the sibling imdb_name_awards or the many other imdb_title_* tools. An agent cannot tell from this text whether it returns award wins, nominations, or a list of ceremonies.

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 when-to-use guidance at all. With 0 required parameters and a sibling imdb_name_awards, the description should at minimum say whether this takes a title id versus a URL and when to prefer it over the generic imdb_title tool; it says nothing.

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