imdb_title_public_facts_analysis

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

No annotations provided, so description carries full burden. Discloses that it returns 'summary metrics' and adds a disclaimer ('not viewing advice'). Also contradicts schema (both params optional) by requiring exactly one parameter, which is helpful. However, no details on output format, auth needs, or rate limits.

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?

Two sentences with no wasted words. First sentence front-loads the core purpose and scope. Second sentence adds critical usage constraint and a necessary disclaimer. Every sentence earns its place.

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?

Given no output schema and no annotations, the description omits details on what 'summary metrics' means (e.g., counts, averages, categories). For an analysis tool, more specificity would help an agent set expectations. However, sibling tools exist and the description covers the essential inputs and purpose.

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 100% with descriptions for id and url. Description adds meaningful constraint ('pass exactly one of id or url') and clarifies url format ('absolute https://...'), improving usability beyond the schema alone.

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?

Describes a specific verb ('returns') and resource ('derived public-page summary metrics') for IMDb title facts. Distinguishes from sibling tools (e.g., imdb_title_trivia, imdb_title_goofs) which return raw or individual category data, making clear this is an aggregate analysis endpoint.

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?

Provides clear parameter usage ('pass exactly one of id or url') but does not explicitly state when to use this tool versus sibling tools for individual fact categories. Usage context is implied as an aggregate, but no exclusions or alternatives are named.

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